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. Datadog mentioned
   If you're pre-Series A with a monolith or a handful of services, Sentry alone covers 80% of what you need and costs ~1% of what Datadog does.
3. Grafana mentioned
   Grafana Cloud - the best "real APM" free tier.
4. Grafana Cloud mentioned
   Grafana Cloud - the best "real APM" free tier.
5. Cloud mentioned
   Grafana Cloud - the best "real APM" free tier.
6. APM mentioned
   Grafana Cloud - the best "real APM" free tier.
7. OpenTelemetry mentioned
   It's OpenTelemetry/Prometheus-native, so your instrumentation is portable - you can leave without re-instrumenting.
8. New Relic mentioned
   New Relic - best if you want managed UX with one meter.
9. SigNoz mentioned
   SigNoz - if you're cost-sensitive and have infra chops.
10. per-seat mentioned
    OpenTelemetry-native, self-host free or cloud from $49/month, with no per-host or per-seat fees ($0.30/GB logs and traces).
11. Honeycomb mentioned
    Honeycomb - if your pain is distributed and weird.
12. multi-year mentioned
    It's the standard now, and it turns your choice from a multi-year marriage into a config change.
13. Sentry + Grafana Cloud mentioned
    Concretely: Sentry + Grafana Cloud, both on free tiers, covers nearly every seed-stage startup for $0 until you have the revenue to care.

The answer, as recorded

## My actual recommendation, in order **1. Sentry - start here.** For most startups, the thing that actually breaks is a specific error in a specific request, not aggregate host CPU. Sentry's error grouping is still best-in-class, and it now does tracing, profiling, and logs too. Free tier is real, Team plan is ~$26/month. If you're pre-Series A with a monolith or a handful of services, Sentry alone covers 80% of what you need and costs ~1% of what Datadog does. **2. Grafana Cloud - the best "real APM" free tier.** 10K active series, 50 GB logs, 50 GB traces, 3 users, no credit card. It's OpenTelemetry/Prometheus-native, so your instrumentation is portable - you can leave without re-instrumenting. Pick this if anyone on the team already knows PromQL. The downside is it's assembly-required; you're wiring Mimir/Loki/Tempo together conceptually, not getting a polished single pane. **3. New Relic - best if you want managed UX with one meter.** 100 GB/month ingest free, full platform including APM, infra, logs, browser, and mobile, with 1 full user. One ingest meter instead of five SKUs is genuinely easier to reason about. The trap is per-user pricing: full-platform users list at ~$549/month, so 10 engineers with full access is $5K+/month before data. Keep most of the team on basic/core seats. **4. SigNoz - if you're cost-sensitive and have infra chops.** OpenTelemetry-native, self-host free or cloud from $49/month, with no per-host or per-seat fees ($0.30/GB logs and traces). Teams report 80% bill reductions migrating off Datadog. The honest caveat: self-hosting ClickHouse is a real job, so only take this path if you'd otherwise be paying four figures a month. **5. Honeycomb - if your pain is distributed and weird.** Event-based pricing with 20M events/month free, Pro at $130/month. It's the right tool specifically for high-cardinality debugging ("why is it slow only for this one customer on this one endpoint"). Overkill for a three-service startup; the correct answer once you have real microservices. **6. Datadog - excellent, and I'd delay it.** Genuinely the most complete product, but the free tier is 5 hosts, 1-day retention, no APM and no logs - i.e. not usable as APM. A 50-host team pays ~$2,300/month before logs and custom metrics. Two specific traps: every metric you send via OpenTelemetry is billed as a *custom* metric (overages at $5 per 100/month, often 30-50% of the bill), and the proprietary agent means leaving requires re-instrumenting everything. ## The one piece of advice that matters most Instrument with **OpenTelemetry**, not a vendor agent, whatever you pick. It's the standard now, and it turns your choice from a multi-year marriage into a config change. The startups that get burned aren't the ones who picked the "wrong" APM - they're the ones who picked a proprietary agent at 5 hosts and discovered at 200 hosts that leaving meant re-instrumenting every service. Concretely: **Sentry + Grafana Cloud, both on free tiers**, covers nearly every seed-stage startup for $0 until you have the revenue to care.
