New Relic and AppDynamics were founded within a year of each other, chased the same APM market for a decade, and then took completely opposite paths. New Relic stayed independent, went public, and in 2020 tore up its own pricing model to bet on consumption. AppDynamics sold to Cisco in January 2017, literally days before its planned IPO, and then got folded into Splunk after Cisco bought Splunk in 2024. Today the product is officially called Splunk AppDynamics, and it lives inside a portfolio where its own parent company also sells a competing product, Splunk Observability Cloud, aimed at cloud-native workloads.
That corporate history isn't trivia. It's the single most important thing to understand before comparing features, because it shapes what each product is for in 2026. New Relic is a unified observability platform trying to cover everything from infrastructure to browser sessions to autonomous AI investigation. Splunk AppDynamics is now positioned quite specifically: deep, agent-based APM for traditional and hybrid enterprise applications, the three-tier Java and .NET estates, the SAP landscapes, the on-premises deployments that cloud-native tools handle poorly. Splunk's own guidance nudges cloud-native buyers toward Observability Cloud instead. So if you're evaluating AppDynamics in 2026, part of what you're evaluating is a roadmap question: how much investment does a product get when its owner sells an alternative?
There are still things AppDynamics does that New Relic doesn't match. Business transaction monitoring, the ability to tie a slow checkout flow to actual revenue impact through Business iQ, remains genuinely differentiated. The on-premises deployment option matters for air-gapped and data-sovereign environments where New Relic, SaaS-only, is disqualified before the demo starts. This comparison works through both sides honestly.
| Feature | New Relic | Splunk AppDynamics |
|---|---|---|
| Primary purpose | Unified full-stack observability SaaS | Enterprise APM with business context |
| Ownership | Independent (public, then private equity) | Cisco, via Splunk (since 2024) |
| Free tier | Yes (100GB/month + 1 full user, forever) | Trial only |
| Deployment | SaaS only | SaaS + on-premises (self-hosted) |
| Pricing model | Per-user seats + data ingest | Per-CPU-core editions (contact sales) |
| Query language | NRQL (unified) | AppDynamics query/ADQL + Splunk integration |
| APM instrumentation | APM agents, eBPF (eAPM), or OTel | Proprietary agents (OTel secondary) |
| Business transaction monitoring | Limited | Yes (core concept, Business iQ) |
| Distributed tracing | Yes (Infinite Tracing) | Yes (business transaction centric) |
| Log management | Yes ($0.40/GB, native) | Via Splunk platform integration |
| Infrastructure monitoring | Yes (native) | Yes (server visibility, add-on) |
| SAP monitoring | No | Yes (dedicated offering) |
| Real user monitoring | Yes (Gartner DEM Leader, 2x) | Yes (browser + mobile, add-on) |
| Session replay | Yes | Yes |
| Synthetic monitoring | Yes | Yes |
| AI capabilities | Applied Intelligence (GA) + SRE Agent (Preview) | Cognition Engine anomaly detection + Splunk AI |
| MCP server | Yes (Preview) | No |
| On-call / status pages | Via integrations | Via Splunk On-Call |
| SOC 2 Type II | Yes | Yes |
| HIPAA | Yes (Data Plus) | Yes |
| FedRAMP | Yes (Moderate, expanding to High) | Yes (via Cisco/Splunk GovCloud offerings) |
The two products organize the world around different core units, and everything else follows from that choice.
New Relic puts logs, metrics, traces, and events into NRDB and makes all of it queryable through NRQL. Alert fires, you click from the alert to the trace to the surrounding logs to the host state without switching tools or query languages. Instrumentation is flexible: language agents, eBPF-based eAPM for zero-code Kubernetes coverage, or plain OpenTelemetry with no surcharge. Pricing is two numbers, $0.40/GB for ingest past the free 100GB/month and $349/month per full platform user on Pro. The seat cost is the thing to watch. It compounds with team size faster than anything else on the bill.
AppDynamics built its architecture around a concept nobody else made central: the business transaction. Not a trace, not a span, but a named business flow like "checkout" or "loan application" that the agents discover automatically and track end to end. Everything hangs off that: baselines are learned per transaction, health rules fire per transaction, and Business iQ correlates transaction performance with business metrics, so you can see that the checkout slowdown is costing roughly this much revenue per minute. For organizations where engineering has to justify itself to a business audience, this framing has real pull, and it's the feature long-time AppDynamics customers actually stay for.
The flip side is that everything runs through proprietary agents. OTel support exists but is secondary, the agents are the product, and the data model is AppDynamics-shaped. There's also the flow map, which does automatic topology discovery well, and the Cognition Engine, which handles anomaly detection and automated root cause analysis against those learned baselines. It's solid, pre-LLM machine learning. What it isn't is anything like the autonomous agent investigation both New Relic and Datadog shipped in the past year. AppDynamics' AI story now depends on what Splunk builds around it, and Splunk's AI investments visibly point at its own platform first.
One thing AppDynamics has that New Relic flatly does not: a supported on-premises deployment. For defense, banking, and government environments where telemetry cannot leave the building, that's not a preference, it's a gate, and New Relic doesn't get through it.
| Architectural factor | New Relic | Splunk AppDynamics |
|---|---|---|
| Core unit | Unified telemetry warehouse (NRDB) | The business transaction |
| Instrumentation | Agents, eBPF, or OTel (native) | Proprietary agents (OTel secondary) |
| Business impact correlation | Limited | Yes (Business iQ) |
| Deployment | SaaS only | SaaS + on-premises |
| Topology | Entity relationships | Flow map (automatic) |
| Roadmap ownership | Independent | Inside Splunk portfolio, alongside a competing product |
Both platforms find the problem and then hand off. Neither includes built-in on-call scheduling with phone and SMS delivery or customer-facing status pages without extra products. Better Stack brings observability and incident response together, so you go from alert to post-mortem in one place.

Both companies built their names here. The difference in 2026 is where each one kept investing.
New Relic's APM covers the standard depth, transaction traces, thread profiling, database query analysis, and adds two things worth calling out. Infinite Tracing looks at 100% of collected traces and keeps the significant ones instead of sampling blindly, which is exactly how you catch the one weird slow request that head-based sampling throws away. And eAPM gives you eBPF-based instrumentation for Kubernetes workloads where deploying language agents to every pod isn't practical. Agent, eBPF, or OTel per workload, whichever fits. Nobody else in this comparison offers all three.
AppDynamics agents remain genuinely deep for the platforms they were built for. Java and .NET instrumentation goes to code level with call graphs and automatic baselining, and the business transaction framing means the trace view answers "which user-facing flow is hurting" rather than just "which service is slow." For monolithic and three-tier applications, the kind AppDynamics grew up monitoring, it's still one of the best tools available.
The strain shows at the modern edges. OpenTelemetry is bolted on rather than native, so an OTel-first stack loses much of what makes AppDynamics special. Cloud-native and serverless coverage lags what New Relic, Datadog, and even Splunk's own Observability Cloud provide, which is precisely why Splunk positions the two products the way it does. The UI hasn't had the kind of overhaul New Relic shipped, and users coming from newer tools tend to notice. None of this makes it a bad product. It makes it a product with a specific, and narrowing, sweet spot.
| APM / tracing | New Relic | Splunk AppDynamics |
|---|---|---|
| Instrumentation options | Agents, eBPF, OTel (all native) | Proprietary agents |
| Code-level depth (Java/.NET) | Yes | Yes (particularly deep) |
| Business transaction framing | No | Yes (core differentiator) |
| Trace retention | Infinite Tracing (smart) | Standard |
| OTel treatment | Native, no surcharge | Secondary |
| Cloud-native / serverless | Strong | Weaker (steered to Observability Cloud) |
This is where the comparison stops being APM vs APM and becomes platform vs portfolio.
New Relic's logs ($0.40/GB, everything searchable, no query fees, seven-year retention available) and infrastructure monitoring live in the same NRDB as APM, so cross-signal correlation is just there. One product, one bill, one query language.
AppDynamics handles logs differently: the answer is Splunk. Log analytics for AppDynamics customers increasingly means integration with the Splunk platform, which is, to be fair, the strongest log analytics product in the industry.
But it's a separate product, separately licensed, with its own famously substantial pricing. Infrastructure monitoring exists in AppDynamics as Server Visibility, an add-on scoped to supporting APM rather than a standalone infrastructure product. The pattern repeats across the portfolio: the capability exists somewhere in the Cisco/Splunk universe, but assembling it means multiple SKUs, multiple consoles, and a licensing conversation that takes a while.
Whether that's a problem depends on where you sit. If your organization already runs Splunk Enterprise for security and IT, AppDynamics slots into an ecosystem you've bought anyway, and the integration story is a benefit. If you're starting fresh, New Relic's everything-in-one-place model is simply less to buy, learn, and stitch together.
| Capability | New Relic | Splunk AppDynamics |
|---|---|---|
| Log management | Native ($0.40/GB, no query fees) | Via Splunk platform (separate license) |
| Infrastructure monitoring | Native, full product | Server Visibility add-on |
| Cross-signal correlation | One database, automatic | Across products, via integration |
| Products to buy for full coverage | One | Several |
Better Stack keeps logs, metrics, traces, uptime, and incident management in one warehouse with SQL querying and one volume-based bill, at $0.10/GB log ingestion with no per-query fees and no per-host or per-core math.

New Relic's DEM suite covers browser RUM, mobile RUM (iOS, Android, React Native, Flutter), session replay, synthetic monitoring, product analytics, and experiments, and New Relic has been a Gartner Magic Quadrant Leader for DEM two years running. Everything correlates to backend traces automatically through the shared backend.
AppDynamics offers browser and mobile RUM, session replay, and synthetic monitoring as End User Monitoring add-ons, and the business transaction correlation carries through, so a slow mobile interaction ties back to the backend flow and its business impact.
The capability set is respectable. The investment trajectory is the question, since Splunk's RUM and synthetics energy visibly flows to Observability Cloud, and analyst recognition in this category has gone New Relic's way.
| Digital experience | New Relic | Splunk AppDynamics |
|---|---|---|
| Browser RUM | Yes (Gartner DEM Leader, 2x) | Yes (add-on) |
| Mobile RUM | Yes (4 frameworks) | Yes |
| Session replay | Yes | Yes |
| Synthetic monitoring | Yes | Yes |
| Product analytics / experiments | Yes | No |
| Business impact correlation | Limited | Yes (through Business iQ) |
Honest version: neither of these is the AI leader in observability right now, but they're behind in different ways.
New Relic's Applied Intelligence (alert correlation, noise reduction, incident summaries) has been GA for years and works well. The newer layer, the SRE Agent that fires on alert and investigates autonomously, plus the Agentic Platform and MCP server, launched in February 2026 and remains in Preview. The direction is right and the architecture matches where the industry is going, but you're buying a preview.
AppDynamics has the Cognition Engine: anomaly detection against learned per-transaction baselines and automated root cause analysis that ranks suspected causes. It predates the LLM wave and does its job, and for the stable, well-baselined enterprise apps AppDynamics targets, learned baselines genuinely work. What's missing is everything after that. No autonomous investigation agent, no MCP server, no natural language interface of its own, and the generative AI roadmap runs through Splunk AI, whose center of gravity is the Splunk platform. If AI-assisted operations is a primary criterion, this category isn't close.
| AI capability | New Relic | Splunk AppDynamics |
|---|---|---|
| Alert correlation / noise reduction | Yes (Applied Intelligence, GA) | Yes (Cognition Engine) |
| Anomaly detection | Yes | Yes (per-transaction baselines) |
| Autonomous investigation | SRE Agent (Preview) | No |
| MCP server | Yes (Preview) | No |
| Natural language interface | Agentic Platform (Preview) | Via Splunk AI (platform-first) |
Better Stack's AI SRE activates autonomously during incidents, investigates across logs, traces, and deployments, and delivers its hypothesis into a live incident with the on-call engineer already paged. Included in the platform, not a preview and not an add-on.

Two models that fail in different ways: one is transparent and expensive per person, the other is opaque and expensive per core.
New Relic publishes everything. Free tier of 100GB/month plus one full platform user, forever. Past that, $0.40/GB ingest and $349/month per full platform user on Pro, with the Standard-to-Pro cliff arriving at the sixth user. You can price a deployment on a napkin, and the napkin will be roughly right. The seat line dominates for most teams: 15 engineers needing full access is $5,235/month before a byte of telemetry.
AppDynamics prices per CPU core, in editions (historically Infrastructure Monitoring, Premium, and Enterprise tiers, with RUM and other capabilities as add-ons), and the current rate card sits behind a sales conversation on Splunk's pricing page. Per-core pricing has a specific failure mode worth understanding: modern hardware is dense. A 32-core production host is 32 units of licensing for the same application a 4-core VM ran a decade ago, and containerized environments where cores are shared make the counting genuinely contentious. Enterprise agreements bundle and discount all of this, especially if AppDynamics rides along a larger Cisco/Splunk agreement, but you won't know your number until procurement does its dance.
A rough sketch rather than false precision: for a mid-size deployment (100 hosts, 15 engineers), New Relic lands somewhere around $5,600 to $5,900/month at list. AppDynamics at published historical per-core rates for its Premium tier would exceed that on core count alone for typical host sizes, before RUM add-ons, but actual enterprise pricing varies too widely to state a fair number. The honest guidance is to get the real quote and compare it against the napkin math New Relic makes possible.
| Pricing factor | New Relic | Splunk AppDynamics |
|---|---|---|
| Price transparency | Full (public rate card) | Contact sales |
| Free tier | Yes (100GB + 1 user, forever) | Trial only |
| Cost anchored to | Engineer headcount + ingest | CPU cores + edition + add-ons |
| Sensitive to | Team size | Host density, core counts |
| Self-serve start | Yes | No |
| Enterprise bundling | Independent negotiation | Can ride Cisco/Splunk agreements |
New Relic gaps worth knowing:
Splunk AppDynamics gaps worth knowing:
There's a version of this decision that's easy. If your estate is cloud-native, your instrumentation is OpenTelemetry, and your team wants one platform with public pricing and a modern AI trajectory, New Relic wins this matchup without much argument. The free tier means you can prove it on your own workloads before spending anything, and the main thing to budget carefully is seats.
The harder version is the one AppDynamics was built for. If you run large Java and .NET estates, SAP, hybrid infrastructure with on-premises requirements, and an organization that needs engineering performance translated into business impact, AppDynamics still does things in that world that nobody else quite does, and Business iQ is not a checkbox New Relic can tick. If your company already has a Cisco or Splunk enterprise agreement, the commercial path may be smoother than any standalone purchase.
But go in with your eyes open about the trajectory. AppDynamics in 2026 is a product two acquisitions deep, positioned by its own parent for the traditional half of the market while investment flows to its cloud-native sibling. That can still be the right purchase for the right estate. It's just a purchase you should make because it fits your applications today, with a plan for where those applications are going, not because of where the product is heading. New Relic, whatever its costs, controls its own roadmap. That difference doesn't show up on a feature table, and over a three-year contract it matters more than most rows that do.
Neither New Relic nor Splunk AppDynamics includes uptime monitoring, on-call scheduling with phone and SMS, incident management, and customer-facing status pages as one product. Better Stack brings all of that together with logs, metrics, and traces, with usage-based pricing and no per-seat or per-core fees.
