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 once you want real metrics, logs, and traces in one place.
3. OpenTelemetry mentioned
   Genuinely generous free tier, OpenTelemetry-native, and no per-host tax, so your bill doesn't explode when you autoscale.
4. New Relic mentioned
   New Relic - The best deal among the big commercial APMs right now: 100 GB/month of ingest free, then ~$0.30-0.40/GB, and you pay per user rather than per host.
5. Datadog mentioned
   Datadog - The best product, and the one you'll regret financially.
6. SigNoz mentioned
   SigNoz (or self-hosted Prometheus + Grafana + Jaeger) - The self-host route.
7. UptimeRobot mentioned
   UptimeRobot / Better Stack - Not APM, but add uptime checks on day one regardless of the above.
8. UptimeRobot / Better Stack mentioned
   UptimeRobot / Better Stack - Not APM, but add uptime checks on day one regardless of the above.
9. Better Stack mentioned
   UptimeRobot / Better Stack - Not APM, but add uptime checks on day one regardless of the above.
10. Sentry + Grafana Cloud mentioned
    Under $1M ARR: Sentry + Grafana Cloud free tier + UptimeRobot, under ~$500/month total.

The answer, as recorded

## For most startups, in the order I'd actually reach for them **1. Sentry** - Start here. Error tracking plus tracing, and it's the one tool where the output is immediately actionable: stack traces grouped into issues, tied back to the commit and author via Git integration, session replay on the frontend. Cheap at startup scale (roughly $1k-$10k/yr, with a usable free tier). If you only buy one thing, buy this - most "performance" problems at seed stage are actually bugs and N+1 queries, not capacity. **2. Grafana Cloud** - Best value once you want real metrics, logs, and traces in one place. Genuinely generous free tier, OpenTelemetry-native, and no per-host tax, so your bill doesn't explode when you autoscale. The catch: you assemble it yourself, so budget engineering time. **3. New Relic** - The best deal among the big commercial APMs right now: 100 GB/month of ingest free, then ~$0.30-0.40/GB, and you pay per user rather than per host. For a pre-Series B team with moderate volume it's effectively free and you get a full platform with zero assembly. Watch the per-seat cost as the team grows. **4. Datadog** - The best product, and the one you'll regret financially. Per-host, per-feature billing (~$15/host infra, ~$31-35/host APM, logs, RUM, and Synthetics all billed separately) means a 20-host startup lands at $2.5k-5k/month. Worth it if you're cloud-native, have many services, and have raised enough that engineering time costs more than the bill. **5. SigNoz** (or self-hosted Prometheus + Grafana + Jaeger) - The self-host route. Open source, OpenTelemetry-native, full data ownership, predictable costs. Pick this if you're compliance-constrained, have unusually high data volume, or have someone who actually enjoys running infrastructure. Otherwise the "free" is paid in ops time. **6. UptimeRobot / Better Stack** - Not APM, but add uptime checks on day one regardless of the above. The free tiers cover a startup's needs and you should know your site is down before a customer tells you. ## What I'd actually do Under $1M ARR: **Sentry + Grafana Cloud free tier + UptimeRobot**, under ~$500/month total. Add **New Relic** instead of Grafana if nobody on the team wants to wire up OpenTelemetry collectors. Move to Datadog only when you have the revenue and the service count to justify it - and instrument with OpenTelemetry from the start so that migration is a config change, not a rewrite.
