Every incident tool claims to cut response time, but they rarely mean the same clock. OnPage is built to shrink the minutes between an alert firing and a person acknowledging it, the number most teams report as MTTA. Rootly is built to shrink everything after that, from the first message in the channel to the moment service is restored, the number that drives MTTR. Both are worth improving. They just fail for different reasons, and each tool is designed around one of those failures.
If your incidents usually go wrong because nobody answers, the second clock never starts. If someone answers right away and then the next hour is confusion, a faster acknowledgment changes little. Knowing which clock hurts you most is the quickest way to choose between these two.
The products reflect that split. OnPage is built to make sure a page cannot be ignored: its alerts break through silent mode and repeat until someone responds, and its compliant messaging has won it customers in hospitals alongside IT teams and MSPs. Rootly picks up once someone is awake. Rootly is a chat-first response platform for engineering teams that runs incidents in Slack or Teams through channels, roles, and workflows, with AI help included and a deeper AI SRE available at extra cost.
This comparison follows both clocks, then covers on-call, healthcare and MSP needs, AI, status pages, telemetry, and list-price costs for 25 people.
Here are the headline differences. Most rows sort neatly onto one clock or the other.
| Category | Rootly | OnPage |
|---|---|---|
| Clock it targets | Time to resolve | Time to acknowledge |
| Typical responder | Engineer in Slack or Teams | Technician, administrator, or clinician on a phone |
| Rings until acknowledged | Escalates on no response | ✔, Alert-Until-Read, up to 8 hours |
| Overrides silent mode | Mobile app alerts | ✔, by design |
| Incident channels and roles | ✔, automatic | ✘ |
| Lifecycle workflows | ✔ | Rules-based routing |
| On-call | Separate license, $20 per user | Included in every plan |
| Shadow rotations | ✔ | ✘ |
| HIPAA-compliant messaging | ✘ | ✔, with a BAA |

| Entry price with on-call | $40 per user for response and on-call | $13.99 per user |
| Logs, metrics, traces | ✘ | ✘ |
OnPage puts almost all of its engineering into this part of the incident.
Its best-known feature, Alert-Until-Read, makes a critical page ignore the phone's silent and do-not-disturb settings, play a distinct tone, and keep going for up to eight hours until the recipient acknowledges. If they do not, OnPage moves to the next person on the escalation policy, and backup delivery paths cover the case where one channel fails. Calls, texts, and app alerts are all part of the plan, not extras.
That focus is the reason teams pick OnPage over general-purpose pagers, and our PagerDuty vs OnPage comparison shows how its persistence holds up against the best-known one.
Rootly On-Call handles this clock competently but less stubbornly. It pages through its mobile app and other channels, escalates when nobody responds, and can route inbound phone calls to whoever is on duty. It is designed for engineers who keep a phone nearby and check Slack, not for a clinician whose phone sits silenced in a coat pocket.
| Acknowledgment | Rootly | OnPage |
|---|---|---|
| Persistent alert until acknowledged | ✘ | ✔ |
| Overrides silent and do-not-disturb | App dependent | ✔ |
| Escalation on no response | ✔ | ✔, with redundancy |
| SMS and voice | Part of On-Call | ✔, included |
| Inbound call routing | ✔ | ✔ |
OnPage makes sure an alert gets answered and Rootly organizes what follows, but both start the clock only after another tool decides something is wrong. Better Stack runs the uptime checks, heartbeats, and log alerts itself, double-checks failures from several locations, and sends the page itself, so detection and acknowledgment happen in one place.
The fastest acknowledgment starts with the earliest detection. See Better Stack uptime monitoring.
Rootly is built for what happens once someone has answered.
As soon as someone declares an incident, Rootly creates a Slack or Teams channel for it, hands out roles such as incident commander and communications lead, starts a timeline, and prompts the lead with next steps. Workflows react as the incident develops, bringing in more people when severity rises, opening tickets, posting updates, and refreshing the status page. The service catalog tells Rootly which team owns the affected service.
OnPage does little here. Responders can message each other securely and manage pages from Slack or Teams, and notes and acknowledgments sync to tickets, but it stops short of the coordination itself: there is no incident channel, no role assignment, and no running log of decisions. For one technician fixing one problem, that is fine. For several engineers working an unclear outage together, the coordination has to happen somewhere else.
| Resolution | Rootly | OnPage |
|---|---|---|
| Automatic incident channel | ✔ | ✘ |
| Roles and prompts for the lead | ✔ | ✘ |
| Lifecycle workflows | ✔ | ✘ |
| Service ownership | ✔, catalog | ✘ |
| Secure team messaging | Chat channel | ✔ |
| Record of the response | Timeline and retrospective | Alert history and reports |
Rootly coordinates the people fixing an incident, and OnPage keeps them messaging, but proving a fix worked usually happens in yet another tool. In Better Stack, the people on the incident can stream the affected service's logs right where they were paged and watch the error rate fall.
Resolution time drops when the proof of a fix is on the same screen as the incident. See Better Stack log management.
Both cover rotations, overrides, and escalation. The extras and the pricing differ.
OnPage handles multiple concurrent schedules for teams spread across sites, with backups and escalation tiers for each, and it guards against holes in coverage when someone enters a shift incorrectly. On-call is part of every plan.
Rootly sells on-call as its own product at $20 per user. It adds shadow rotations so newer engineers can follow along before taking primary duty, and it warns when a schedule leaves gaps.
| On-call | Rootly | OnPage |
|---|---|---|
| Multiple schedules and rotations | ✔ | ✔ |
| Gap protection | Coverage warnings | ✔, fail-safe scheduler |
| Shadow rotations | ✔ | ✘ |
| Pricing | $20 per user, separate | Included |
Two groups of buyers will find OnPage hard to replace with Rootly.
Hospitals and clinics rely on OnPage because staff can exchange patient information in the same app that pages them, under HIPAA rules and a signed BAA. The vendor sells dedicated healthcare products too, from replacing old beepers to scheduling clinical on-call. Rootly is not positioned as a clinical messaging tool.
Managed service providers use OnPage's integrations with ConnectWise and Autotask, the PSA platforms most MSPs run on. A monitoring alert creates the client ticket, and acknowledgments and notes sync back, so the client record stays complete. Rootly integrates with Jira, ServiceNow, and other engineering trackers, but not with PSA tools.
| Industry fit | Rootly | OnPage |
|---|---|---|
| HIPAA-compliant clinical messaging | ✘ | ✔ |
| ConnectWise and Autotask | ✘ | ✔ |
| Jira and ServiceNow | ✔ | ✔ |
| Mass notification | ✘ | ✔ |
Only Rootly has AI features, and it has a lot of them.
Rootly's entry plan already puts an AI helper in each incident channel to recap events, field questions, and start the write-up. On top of that, Rootly sells an AI SRE that looks into deploys, nearby alerts, and earlier incidents on its own and suggests a cause with a confidence rating. For a closer look at how that agent works, see Better Stack AI SRE vs Rootly AI SRE.
Rootly's MCP server, generally available since March 2026, lets assistants such as Claude work with incidents, alerts, schedules, and workflows. OnPage offers neither AI nor an MCP server, which its buyers rarely miss, because getting the page through is what they pay for.
| AI and MCP | Rootly | OnPage |
|---|---|---|
| Incident summaries | ✔ | ✘ |
| AI retrospective drafts | ✔ | ✘ |
| Root-cause hypothesis | ✔, AI SRE | ✘ |
| MCP server | ✔ | ✘ |
OnPage has no AI, and Rootly's AI SRE reasons from alerts, changes, and past incidents passed in by other tools. Better Stack's AI SRE queries the logs, metrics, and traces stored in the same platform that pages you, and its MCP server gives Claude or Cursor that same access.
An AI that reads the telemetry can explain a failure instead of guessing at it. See Better Stack AI SRE.
Rootly includes status pages on Essentials, and its workflows can post customer updates as severity changes.
OnPage has no customer-facing status pages, though it does offer mass notification for reaching a whole workforce. Its post-incident reports focus on the acknowledgment clock: who was paged, how long they took, and how escalation unfolded, useful when an MSP reviews service with a client or a hospital documents its response. Rootly's reports focus on the response, with AI-drafted retrospectives and follow-ups synced to trackers.
| Status and reporting | Rootly | OnPage |
|---|---|---|
| Customer status pages | ✔ | ✘ |
| Mass notification | ✘ | ✔ |
| Acknowledgment and escalation reports | Incident metrics | ✔ |
| Retrospectives | ✔, AI-drafted | Post-incident reports |
Neither Rootly nor OnPage stores logs, metrics, or traces, or runs uptime checks. Both depend on monitoring tools to raise the alert, and responders return to them to learn what actually broke. If you want alerting and the data behind it from one vendor, our Better Stack vs OnPage comparison looks at that option directly.
| Observability | Rootly | OnPage |
|---|---|---|
| Logs, metrics, traces | ✘ | ✘ |
| Uptime monitoring | ✘ | ✘ |
| Where alerts come from | Connected integrations | Connected integrations |
Rootly and OnPage both know an incident is happening, but neither can show which request broke. Better Stack records traces alongside logs and metrics, so a responder can move from the alert to the failing span without leaving the platform that paged them.
Both clocks stop sooner when the evidence is one click from the alert. Explore Better Stack tracing.
OnPage costs $13.99 per user per month on its Base plan with annual billing, or $16.99 paid quarterly, with Enterprise Silver at $22.99 and Enterprise Gold at $28.99 annually. Every plan includes on-call, integrations, and support.
Rootly's response and on-call products cost $20 a user each per month, the AI SRE is quoted on request, and there is no free tier.
For 25 people with 10 on rotation, at annual list prices:
| Cost component | Rootly Essentials | OnPage Base | OnPage Enterprise Silver |
|---|---|---|---|
| If all 25 need seats | 25 at $20 plus 10 at $20 for on-call, so $700 | 25 at $13.99, so about $350 | 25 at $22.99, so about $575 |
| If only the 10 on rotation need seats | 10 at $20 plus 10 at $20, so $400 | 10 at $13.99, so about $140 | 10 at $22.99, so about $230 |
| Status pages | Included | Separate product | Separate product |
| AI | Assistant included, AI SRE extra | ✘ | ✘ |
| HIPAA messaging | ✘ | ✔ | ✔ |
OnPage costs roughly half as much at either team shape. Rootly's extra spend buys the channel-based response, workflows, status pages, and AI.
Go with OnPage when slow or missed acknowledgments are what hurt, particularly if your responders are rarely at a desk. Clinical teams that need compliant messaging, MSPs built around ConnectWise or Autotask, and operations groups that want loud, persistent paging without a large bill are its best fit. Plan for a separate status page tool and little help once someone is awake.
Choose Rootly if your pages get answered quickly and the trouble starts afterward, with too many people, unclear roles, and nobody writing things down. It suits engineering teams working in Slack or Teams who want workflows, status pages, and AI help with the cause. Teams set on a chat-first tool usually weigh Rootly against incident.io next, which our incident.io vs Rootly comparison covers.
Each of these tools is very good at one clock and largely ignores the other. OnPage wins the minutes before someone answers, and Rootly wins the hour after.
So pull the numbers from your last few incidents. If time to acknowledge is the ugly one, OnPage will fix it for less money than Rootly. If time to acknowledge looks fine and time to resolve does not, a louder pager will not help you.
Rootly's MCP server exposes incident data, and OnPage has no MCP server at all, but neither can give an AI assistant your logs or traces, because neither stores them. Better Stack's MCP server covers the whole platform, so Claude or Cursor can query your logs with SQL, check who is on call, acknowledge an incident, and build a dashboard chart in one conversation.
With incidents and telemetry behind one MCP endpoint, your assistant can investigate and respond without switching tools. Try Better Stack.
