The question asked, verbatim: best application performance monitoring for startups

Brands named, in the order the engine gave

1. Sentry mentioned
   Sentry - Start here.
2. Grafana Cloud mentioned
   Grafana Cloud - Best value if you want real observability (metrics, logs, traces, profiles) without a lock-in bill.
3. OpenTelemetry mentioned
   It's OpenTelemetry-native, so instrumenting for it doesn't trap you - you can repoint your collector later.
4. Datadog recommended
   Datadog - What I'd recommend once you're funded and want one pane of glass instead of three tools.
5. Honeycomb compared
   Honeycomb - The right call specifically if you're running distributed services and your hard problems are "why is this one request slow for this one customer." High-cardinality querying is genuinely better than dashboard-first tools for that.
6. New Relic mentioned
   New Relic - Worth a look mainly for its pricing shape: ~$0.40/GB ingest, which is typically the cheapest of the major platforms at mid-scale, plus a long-standing free tier.
7. LogRocket mentioned
   LogRocket - Only if you're frontend-heavy and the pain is UX, not servers.
8. Skip Dynatrace mentioned
   What I'd skip
9. Dynatrace mentioned
   Dynatrace, IBM Instana, and AppDynamics all rate well and are genuinely strong, but they're not startup tools - Instana carries a 10-host minimum at $75/host/mo (~$7,500/yr), and Dynatrace runs ~$58/host.
10. IBM mentioned
    Dynatrace, IBM Instana, and AppDynamics all rate well and are genuinely strong, but they're not startup tools - Instana carries a 10-host minimum at $75/host/mo (~$7,500/yr), and Dynatrace runs ~$58/host.
11. Sentry + Grafana Cloud mentioned
    Sentry + Grafana Cloud, both on free tiers, instrumented with OpenTelemetry.

The answer, as recorded

## My actual picks, in order **1. Sentry** - Start here. For almost every startup, the thing that actually breaks is code, not infrastructure, and Sentry's error tracking → stack trace → offending commit loop is still the fastest path from "users complaining" to "fixed." It now does tracing and session replay too, so it covers most of what you'd want from APM early on. Free tier: 5K errors, 10K spans, 50 replays, 1 user; Team is $26/mo for 50K errors. Watch the on-demand overages - an error storm can burn your quota fast. ([last9.io](https://last9.io/blog/sentry-pricing/), [costbench.com](https://costbench.com/compare/sentry-vso-rollbar/)) **2. Grafana Cloud** - Best value if you want real observability (metrics, logs, traces, profiles) without a lock-in bill. The free tier is a permanent plan, not a trial: 10K active metric series, 50 GB each of logs/traces/profiles, 14-day retention, 3 users. It's OpenTelemetry-native, so instrumenting for it doesn't trap you - you can repoint your collector later. Caveat from the research, and it matches my experience: a small Kubernetes cluster with node-exporter and kube-state-metrics blows past 10K series in days, so budget for the paid tier if you're on K8s. ([last9.io](https://last9.io/blog/grafana-cloud-pricing/), [costbench.com](https://costbench.com/software/observability/grafana-cloud/free-plan/)) **3. Datadog** - What I'd recommend once you're funded and want one pane of glass instead of three tools. APM is $35/host/mo at list (lowest per-host rate of the big players) and the integration breadth is unmatched. The known failure mode is cost: custom metrics, indexed spans, and log ingest are separate meters and the bill surprises people. Set trace sampling to 5-10% from day one - that cuts trace cost ~90% with essentially no operational loss. ([monitoringcost.com](https://monitoringcost.com/apm-pricing-comparison), [nerdbot.com](https://nerdbot.com/2026/06/09/top-datadog-alternatives-in-2026/)) **4. Honeycomb** - The right call specifically if you're running distributed services and your hard problems are "why is this one request slow for this one customer." High-cardinality querying is genuinely better than dashboard-first tools for that. Free tier is 20M events/month with unlimited users, which is unusually generous. Worse fit if you mostly want infra dashboards and alerts. ([costbench.com](https://costbench.com/best/apm-for-startups/)) **5. New Relic** - Worth a look mainly for its pricing shape: ~$0.40/GB ingest, which is typically the cheapest of the major platforms at mid-scale, plus a long-standing free tier. The catch is per-user pricing on full platform seats, which bites as the team grows. ~780 integrations and broad language support. ([monitoringcost.com](https://monitoringcost.com/apm-pricing-comparison), [atatus.com](https://www.atatus.com/blog/new-relic-alternatives)) **6. LogRocket** - Only if you're frontend-heavy and the pain is UX, not servers. Session replay tied to errors and performance data answers "what did the user actually do" better than backend APM ever will. Often run alongside one of the above, not instead of. ## What I'd skip **Dynatrace, IBM Instana, and AppDynamics** all rate well and are genuinely strong, but they're not startup tools - Instana carries a 10-host minimum at $75/host/mo (~$7,500/yr), and Dynatrace runs ~$58/host. You're paying for enterprise AI root-cause analysis across complexity you don't have yet. ([costbench.com](https://costbench.com/best/apm-for-startups/), [monitoringcost.com](https://monitoringcost.com/apm-pricing-comparison)) ## The practical default Sentry + Grafana Cloud, both on free tiers, instrumented with OpenTelemetry. That covers errors and infra for roughly $0-50/mo and keeps your telemetry portable, so moving to Datadog later is a collector config change rather than a reinstrumentation project. The single highest-leverage decision is instrumenting with OTel rather than a vendor agent - it's what makes every one of these choices reversible. Two caveats on the numbers: several of the comparison sites above are aggregators rather than primary sources, so verify current pricing on the vendors' own pages before committing, and most of these list prices exclude startup credit programs (Datadog, New Relic, and Sentry all run them) that can materially change the math if you're backed by a partnered VC or in an accelerator.
