Better Stack vs OnlineOrNot: A Complete Comparison for 2026

OnlineOrNot is built around one thing: telling you when your website is down. It does that job well. You get 30-second check intervals, multi-location verification to cut down on false positives, clean status pages, and enough alerting integrations to slot into whatever on-call stack you already have running. If that is all you need from a monitoring tool, it is a capable choice at a fair price.

Better Stack covers that same ground but goes quite a bit further. Uptime monitoring is one piece of a platform that also includes log management, distributed tracing, infrastructure metrics, real user monitoring, error tracking, and built-in incident management with native on-call scheduling. The real question here is whether that broader scope is worth anything to you, or whether it is just extra complexity you would rather avoid paying for.

The answer to that question mostly comes down to what happens after the alert fires. OnlineOrNot tells you something is wrong. Better Stack also helps you work out why.

Quick comparison at a glance

Platform scope

OnlineOrNot is what the industry usually calls a single-purpose monitoring tool. It checks URLs, verifies SSL certificates, runs browser scripts, tracks heartbeats, and fires alerts. The product is deliberately narrow, and that is a genuine design choice rather than something the team forgot to ship. You get a clean, focused experience without features you will never use.

Better Stack takes the opposite approach. It is a unified observability platform where uptime monitoring is one of seven or eight distinct capabilities living under a single roof. The relevant question when comparing the two is not which one has more features, it is whether running your uptime checks in isolation from your logs, traces, and error data creates friction when something goes wrong at a bad time.

What happens after the alert

Picture the simplest scenario: your uptime monitor fires at 2am and your endpoint is not responding. With OnlineOrNot, that is where the platform's direct contribution ends. From there, you are switching to whatever log aggregator, tracing tool, or APM you use separately to figure out the cause. That might mean logging into Datadog, digging through CloudWatch, or SSH-ing into a server while half asleep.

With Better Stack, the alert and the investigation live in the same place. The monitor fires, the incident gets created, whoever is on-call gets paged, and the logs, traces, and recent error spikes for that service are sitting right there in the same interface. Whether that matters depends entirely on whether you already have a solid observability stack sitting behind the alert, or whether you are stitching things together from multiple disconnected products every time something breaks.

Uptime monitoring

Both platforms offer HTTP/HTTPS checks, keyword matching, SSL certificate monitoring, multi-location verification, and multi-step confirmation before alerting. At the core, the feature parity is close enough that neither platform has a meaningful edge when it comes to basic uptime detection. Where they diverge is in what surrounds that core.

Better Stack: uptime monitoring

Better Stack's uptime monitoring checks your sites and APIs from multiple global locations on intervals as tight as 30 seconds. Before it fires an alert, it runs multi-step verification to make sure you are only paged about real problems. Here is how monitors work in practice:

On top of basic HTTP checks, you can set up TCP/UDP port monitoring, DNS server monitoring, ping monitoring, and IPv6. For more detailed configuration, you can define maintenance windows, geo-specific check locations, response time thresholds, and custom HTTP methods, headers, and body parameters. The advanced configuration video below walks through what that looks like:

The bigger difference is what happens when a check fails. In Better Stack, a failed check creates an incident automatically, triggers on-call escalations, and pushes status page updates, all within the same platform. The monitor failure does not just send an email and stop there.

If you are migrating from another monitoring tool, you can import your existing monitors in bulk rather than entering them one by one:

OnlineOrNot: uptime monitoring

OnlineOrNot checks your websites, APIs, and endpoints every 30 seconds from multiple regions. It runs each check at least twice before firing an alert, which does a good job of cutting out the single-location false positives that catch people on simpler tools. You can configure HTTP methods, headers, and request bodies per check, and pick which regions you want to monitor from.

SSL certificate expiration monitoring is included, and keyword checks let you verify that a page is actually returning the right content rather than just a 200 status. Audit logs are available on Pro plans, so you can track configuration changes over time.

What OnlineOrNot cannot do is help you understand why a check failed. It tells you the endpoint stopped responding. The investigation happens somewhere else.

Transaction monitoring (Playwright)

Both platforms support browser-based transaction monitoring using real browser instances, and both are worth using if you need to verify that actual user flows are working, not just that a URL is reachable.

Better Stack runs Playwright-based checks that simulate full user journeys through your application: form submissions, login flows, checkout sequences. The checks render in full Chrome, catch JavaScript errors along the way, and produce screenshots and traceroute data when something fails. If you do not want to write Playwright scripts by hand, the codegen tool can generate them for you visually:

Playwright minutes cost $1 per 100 minutes, with multi-location and geo-specific checks included.

OnlineOrNot offers browser check runs as part of its Pro plan, with 3,000 runs included each month. Additional runs cost $4 per 1,000. Like Better Stack, these run in real Chrome browsers. OnlineOrNot's browser checks are a bit simpler than full Playwright scripting, which makes setup faster but limits what you can do with complex multi-step interactions.

Heartbeat monitoring

Both platforms let you monitor cron jobs and scheduled tasks by waiting for a ping on a set schedule. If the ping does not arrive within the grace period you define, an alert fires. It is a simple but genuinely useful feature for catching silent job failures before they turn into data problems.

Better Stack includes 10 heartbeats on the free tier, with additional sets of 10 at $17/month. Checks resolve down to 1-second intervals, and you can manage heartbeats programmatically through the API, Zapier, Terraform, or webhooks:

OnlineOrNot includes heartbeat monitoring as well. It does not show up as a separately priced line item on the pricing page, and check resolution and grace period configuration are broadly comparable to Better Stack at the feature level.

API monitoring

API monitoring overlaps with uptime monitoring, but the depth of assertion support makes a difference when you care about more than just reachability. Checking that an endpoint returns 200 is easy. Checking that the response body contains a specific value, that latency stays within a threshold, or that a multi-step API workflow completes correctly is where the platforms start to show different strengths.

Better Stack: API monitoring

Better Stack's API monitoring supports configurable HTTP methods, custom headers, request body parameters, and response assertions across response codes, body content, response times, and header values. Multi-step incident verification means a single slow response does not wake you up at night:

The observability integration is the part that matters most in practice. When an API check fails, you can jump straight to the logs and traces for that service without leaving the platform. You are not manually correlating a downtime alert with a log search in a separate tab.

OnlineOrNot: API monitoring

OnlineOrNot supports configurable HTTP requests with custom methods, headers, and body parameters for each check. SSL monitoring is included as standard. The platform is focused on availability and correctness rather than offering a deep assertion library.

Reviewers on G2 consistently praise how easy it is to get set up and how cleanly the alerting integrations work. What you do not get is any backend observability once a check fails: OnlineOrNot surfaces the problem, but figuring out what caused it is on you.

Incident management and on-call

This is where the two platforms differ most sharply. Better Stack includes incident management as a native product with built-in on-call scheduling, escalation policies, unlimited phone and SMS alerts, and Slack/Teams-native workflows. OnlineOrNot routes alerts to external on-call tools like PagerDuty, OpsGenie, Incident.io, Spike, and Grafana OnCall rather than managing the on-call workflow itself.

Are you currently paying for a monitoring tool and a separate on-call tool? That is exactly the cost stack Better Stack is designed to collapse into one.

Better Stack: native incident management

Better Stack incident management handles the full incident lifecycle without requiring you to bring in external tools. When a monitor fires, an incident is created, whoever is on-call gets paged by phone, SMS, push notification, or Slack, and a dedicated incident channel opens in your workspace:

On-call scheduling is built in with rotation management, timezone-aware schedules, and automatic handoffs. There is no separate PagerDuty subscription involved:

You can set up primary and secondary on-call coverage natively, so backup escalation chains are defined inside Better Stack rather than in a third-party tool:

Slack-native incident management creates a dedicated channel per incident and puts investigation tools directly inside Slack, so you can acknowledge, escalate, and resolve without leaving the workspace where your conversations are already happening:

If your team works in MS Teams instead, you get the same native experience there:

Advanced escalation policies support multi-tier rules with time-based routing and severity metadata, which is useful for large on-call rotations with complex coverage requirements:

Once an incident closes, Better Stack automatically generates a post-mortem from the incident timeline. That saves you from reconstructing the sequence of events after the fact when everyone just wants to go to sleep:

Better Stack also includes a call routing product that forwards inbound phone calls to whoever is currently on-call and creates incidents from those calls automatically:

On the cost side: Better Stack charges $29/responder/month, so 5 responders comes out to $145/month with unlimited phone and SMS included. If you go with OnlineOrNot plus PagerDuty, you are looking at $15-25/month for OnlineOrNot Pro plus $49-83/user/month for PagerDuty, totaling roughly $260-440/month for the same capability.

OnlineOrNot: alerting via integrations

OnlineOrNot does not include on-call scheduling, escalation policies, or incident management. When an alert fires, it sends notifications to email, SMS, Slack, Discord, PagerDuty, OpsGenie, Incident.io, Grafana OnCall, Spike, Zoom, and webhooks. The actual on-call workflow lives in whichever external tool you have connected.

That model works well if you already have PagerDuty or OpsGenie running and you want to add uptime monitoring without changing your existing incident stack. It becomes a problem if you do not have an on-call tool yet and were hoping to avoid buying one separately.

Status pages

A status page is how you tell your customers something is wrong before they have to find out themselves. Both platforms include them, but they differ in how subscribers get notified, how much you can customize the page, and how the pricing stacks up.

Better Stack: status pages

Better Stack Status Pages sync automatically with incident management. When you declare an incident, the status page updates. When it resolves, the status page reflects that too, without you having to touch it manually:

Subscriber notifications go out via email, SMS, Slack, and webhooks. On OnlineOrNot, subscribers only get email, so if your users prefer Slack updates, that is a gap worth knowing about.

Advanced status page setup covers multi-service architectures, custom CSS and JavaScript, white-labeling to remove the "Powered by Better Stack" footer, and multi-language support for international user bases:

If you need a private status page for internal tools or enterprise customers, you can lock it down with password protection, IP allowlisting, or SSO authentication:

Subscriber management supports bulk import, and you can organize subscribers by service using catalog metadata:

Pricing: 1 public status page is included in the responder plan. Additional pages cost $12/month. Custom CSS/JS is $12/page/month. White-labeling runs $208/page/month. Private pages with password or SSO are $42-208/page/month depending on the access method.

OnlineOrNot: status pages

OnlineOrNot includes one status page on the Pro plan with a custom domain and branded design. Additional pages cost $24/page/month. Private pages are available at $48/page/month.

Subscriber notifications are email only, and white-labeling does not appear to be an option on any plan. The platform supports custom logos, favicons, and custom domains, so you get a professional look without much effort, but you are limited in how far you can push the customization or how you reach your subscribers.

Observability: what OnlineOrNot doesn't cover

This section is about capabilities where OnlineOrNot simply does not have a product. If log management, tracing, infrastructure metrics, error tracking, or real user monitoring are on your list, OnlineOrNot is not in the running for those categories. Better Stack covers all of them.

If you already have dedicated tools for each of these and you are just looking for a clean uptime monitoring layer on top, OnlineOrNot is a reasonable fit. But if you are building out your observability stack from scratch, or you are trying to consolidate tools to cut costs and reduce the number of dashboards you maintain, Better Stack's scope starts to look a lot more attractive.

Log management

Better Stack logs ingests structured logs from any source, stores them in a unified warehouse alongside your metrics and traces, and makes 100% of ingested logs immediately searchable. You do not have to decide upfront which logs are worth indexing. The query interface supports both SQL and PromQL, so you can use whichever you are already comfortable with:

You can transform logs with VRL at ingestion, run analytical queries with SQL, and stream in real time via Live Tail. When a monitor fires, the logs for the affected service are right there in the same interface. You are not copying trace IDs into a separate search bar in another browser tab.

SELECT 
  service_name,
  status_code,
  COUNT(*) as request_count,
  AVG(response_time_ms) as avg_response_time
FROM logs
WHERE timestamp > NOW() - INTERVAL '30 minutes'
  AND status_code >= 500
GROUP BY service_name, status_code
ORDER BY request_count DESC

Pricing: $0.10/GB ingestion + $0.05/GB/month retention. Bundled plans start at $25/month for 40GB.

OnlineOrNot has no log management product.

Distributed tracing and APM

Better Stack's APM uses eBPF to capture distributed traces at the kernel level without any SDK installation or code changes on your side. You deploy the collector to Kubernetes via a single Helm chart, and HTTP/gRPC traffic between services, database queries, and inter-service calls are traced automatically from that point forward:

Frontend-to-backend correlation connects browser session data with backend traces, so a slow page load can be followed all the way through the service call chain to the specific database query that caused it, without switching products.

OpenTelemetry-native, zero lock-in. Traces are stored in OTel format. If you ever want to route them somewhere else, you change a single configuration line. There are no proprietary agents and no migration cost baked into your instrumentation.

When a monitor fires, you can immediately pull up traces for the affected service to see which downstream dependency is failing and what it is waiting on. That is the gap between knowing your site is down and knowing your site is down because the payment service is timing out on the database.

OnlineOrNot has no APM or tracing product.

Infrastructure metrics

Better Stack metrics collects infrastructure and application metrics via Prometheus exporters, OpenTelemetry collectors, or the eBPF-based collector. Metrics live in the same warehouse as your logs and traces, queryable with PromQL or SQL:

Cardinality has no pricing impact in Better Stack. Costs are based on data volume, not on the number of unique metric combinations. So if you are running high-cardinality instrumentation with per-customer or per-deployment metrics, you do not have to strip tags just to keep the bill under control:

If you prefer a visual approach to building charts over writing PromQL, the drag-and-drop chart builder handles the same queries without the query syntax:

Pricing: $0.50/GB/month. 30GB included in bundles.

OnlineOrNot has no infrastructure metrics product.

Real user monitoring

Better Stack RUM captures browser sessions, JavaScript errors, Core Web Vitals (LCP, CLS, INP), and user interaction data. Session replays let you watch how a user moved through a page, with controls to filter by rage clicks, dead clicks, and error-correlated playback. Because your RUM data lives in the same warehouse as logs, metrics, and traces, a frontend error links directly to the backend trace and log entries from that same session.

For 1M web events and 5,000 session replays, Better Stack's cost is well below competing standalone RUM tools. Session replays are priced at $0.00150 each.

Website analytics including referrers, UTM campaign tracking, and entry and exit pages are included at the same ingestion and retention rates as log data. Product analytics with funnel analysis and auto-captured user events are also included, so you can answer questions about user behavior without setting up a separate analytics tool.

OnlineOrNot has no RUM product.

Error tracking

Better Stack Error Tracking accepts Sentry SDK payloads directly, which means you can switch to it without rewriting your instrumentation. Errors are grouped into issues, linked to the distributed trace that caused them, and surfaced with the full request context around the exception:

AI-native debugging integrates with Claude Code and Cursor. Each error issue comes with a pre-built prompt that summarizes the error context: stack trace, related log lines, and the trace that preceded it. You copy the prompt, paste it into your AI coding agent, and get a fix suggestion without reading through a wall of stack trace output:

Pricing: 100,000 exceptions are included free, and additional exceptions cost $0.000050 each. That works out to roughly 6x cheaper than Sentry.

OnlineOrNot has no error tracking product.

AI SRE and MCP server

Connecting AI assistants to your observability data is increasingly useful, and this is a category where the two platforms are not close. Better Stack ships both an AI SRE and an MCP server that is generally available to all customers. OnlineOrNot has neither.

Better Stack: AI SRE and MCP server

AI SRE activates automatically when an incident fires. It reviews your service map, queries relevant logs, checks recent deployments, and delivers a root cause hypothesis before you have had to type a single prompt. At 3am, starting with a hypothesis in front of you is meaningfully faster than starting from a blank Slack channel with nothing but an alert notification:

Better Stack MCP server connects Claude, Cursor, and other MCP-compatible AI assistants directly to your observability data. Instead of copying log snippets into a chat window, your AI assistant can query Better Stack directly, running SQL against your logs, checking who is on-call, acknowledging incidents, or building dashboard charts through natural language:

Setup is a single configuration block:

{
  "mcpServers": {
    "betterstack": {
      "type": "http",
      "url": "https://mcp.betterstack.com"
    }
  }
}

From there, you can ask things like "what monitors are currently down?", "who is on-call right now?", "show me HTTP 500 errors in the last 30 minutes," or "create a dashboard for my API error rate." The MCP server covers uptime monitoring, incident management, log querying, metrics, dashboards, error tracking, and on-call scheduling. You can configure which tools the AI assistant can access, limiting it to read-only if you prefer.

AI SRE is priced at $0.00003 per token. The MCP server is included with your Better Stack account.

OnlineOrNot: no AI SRE, no MCP server

OnlineOrNot does not have an AI SRE or an MCP server. Whatever AI assistance you get comes from connecting notifications to external tools and working from there.

Pricing comparison

OnlineOrNot's pricing is based on monitor count. Better Stack's is based on data volume. For pure uptime monitoring with nothing else, OnlineOrNot is cheaper at low monitor counts. But once you start factoring in on-call tooling, log management, or anything else that most engineering teams actually need, Better Stack comes out cheaper.

Better Stack: pricing

Better Stack separates uptime monitoring from telemetry. The responder license at $29/month includes uptime monitoring with unlimited phone and SMS alerts, on-call scheduling, incident management, status pages, and access to telemetry products.

Uptime monitoring pricing: - 10 monitors and 10 heartbeats: included - Additional 50 monitors: $21/month - Additional 10 heartbeats: $17/month - Playwright transaction checks: $1/100 minutes - Monitors: $0.21/month each

Telemetry pricing: - Logs/Traces: $0.10/GB ingestion + $0.05/GB/month retention - Metrics: $0.50/GB/month - Session replays: $0.00150 each - Error tracking: $0.000050 per exception - Bundled plans start at $25/month (Nano: 40GB logs/traces/metrics)

If you are running 50 monitors and 5 on-call responders, that works out to $21 for monitors plus $145 for responders, so $166/month total. That includes unlimited phone and SMS, on-call scheduling, escalation policies, status pages, post-mortems, and Slack incident channels.

OnlineOrNot: pricing

Free tier: Up to 3 monitors, 3-minute check interval, basic alerting, 1 status page, 2 users.

Pro plan: From $15/month. Includes 10 monitors (additional 25 monitors at $10/month), 30-second check intervals, 3,000 browser check runs per month, SMS alerts, webhooks, on-call integrations, 1 status page, unlimited users, 12-month data retention, and audit logs.

Additional pages: $24/page/month for public pages, $48/page/month for private pages.

Enterprise: Custom pricing with dedicated support, custom integrations, and a 99.9% SLA.

Running 50 monitors on OnlineOrNot comes out to roughly $31/month. Add PagerDuty for 5 users at $49-83/user and you are looking at $260-440/month for just the on-call piece. Total: somewhere between $291 and $471/month, compared to $166/month on Better Stack with everything included.

Enterprise readiness

OnlineOrNot is built for developers, small businesses, and mid-size companies. It has an Enterprise tier, but enterprise features are not the focus of the product. Better Stack is more explicit about targeting enterprise teams, with SSO, SCIM, RBAC, audit logs, data residency options, and dedicated support channels all available.

Better Stack: enterprise features

Better Stack is SOC 2 Type II certified and GDPR compliant, with data stored in DIN ISO/IEC 27001-certified data centers. Enterprise customers get access to:

• SSO/SAML: Google (included free), Azure and Okta ($5/user/month), Generic SAML (enterprise)
• SCIM provisioning: Automated user synchronization with identity providers
• RBAC: Role-based access control with team-level isolation
• Audit logs: $208/month
• Data residency: EU and US regions; optional custom deployment in your own S3 bucket ($208/month)
• Dedicated Slack support channel: Direct access to the Better Stack team
• Named account manager: For enterprise contracts
• SLA: Enterprise SLA available on request
• Custom VPC deployment: Enterprise-tier option

Regular third-party penetration testing is conducted, with reports available to enterprise customers under NDA.

One important caveat: Better Stack is not currently HIPAA compliant. If you are in healthcare and HIPAA is a requirement, that is something to factor into your decision upfront.

OnlineOrNot: enterprise features

OnlineOrNot's Enterprise tier includes custom inclusions, custom integrations, dedicated support, and a 99.9% SLA guarantee. The platform is GDPR compliant. One thing worth noting in OnlineOrNot's favor: audit logs are available on Pro plans, which is a lower bar than Better Stack's $208/month add-on price for the same feature.

SSO, SCIM, and RBAC are not publicly listed on any OnlineOrNot plan. Data residency options and compliance certifications beyond GDPR are not mentioned. If your procurement process requires SOC 2 reports, SSO enforcement, or SCIM provisioning, Better Stack has a more complete story on those fronts.

Final thoughts

OnlineOrNot is a focused product. It monitors uptime well, fires alerts reliably, and connects cleanly with the on-call and incident tools you might already be using. The founder is unusually responsive, the pricing is transparent, and the product does not try to be something it is not. If you want a lightweight monitor that sits in the background and tells you when something stops responding, OnlineOrNot does that job without making you pay for a bunch of features you will never open.

Better Stack is the stronger choice when you want the full picture in one place. You get uptime monitoring with the same core reliability as OnlineOrNot, native on-call scheduling and incident management that eliminates the PagerDuty bill, log management and distributed tracing that tells you why a service failed rather than just that it did, error tracking with AI-native debugging, real user monitoring, and an MCP server that connects your observability data to Claude, Cursor, and other AI assistants. When you add up the cost of OnlineOrNot plus all the external tools you would need to match that scope, Better Stack comes out cheaper.

If uptime monitoring is genuinely all you need and everything else is already covered, OnlineOrNot is a reasonable choice. If you are looking at both platforms because you want observability and not just monitoring, Better Stack is the more complete answer.
