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

Brands named, in the order the engine gave

1. Sentry recommended
   Sentry - Where I'd start for almost any early-stage team.
2. Grafana Cloud recommended
   Grafana Cloud - Best value once you want real infra + app observability together.
3. Datadog compared
   Free tier is unusually large (metrics, logs, traces), it's OpenTelemetry-native, and hosted plans typically land well under Datadog/New Relic - the comparison guides put mid-size Grafana Cloud deployments in the $5-20k/yr range vs.
4. New Relic compared
   Free tier is unusually large (metrics, logs, traces), it's OpenTelemetry-native, and hosted plans typically land well under Datadog/New Relic - the comparison guides put mid-size Grafana Cloud deployments in the $5-20k/yr range vs.
5. SKU Print compared
   If you have a polyglot stack and don't want to think about which SKU covers what, this is the pragmatic pick and usually cheaper than Datadog at mid-market.
6. SigNoz recommended
   SigNoz - The one I'd name if cost is the binding constraint and you have someone who enjoys running infra.
7. Real DRaaS recommended
   Real escape hatch from Datadog pricing without vendor lock-in.
8. Scout APM recommended
   Scout APM - Worth a mention if you're a Rails or Django shop.
9. OpenObserve mentioned

The answer, as recorded

Here's what I'd actually recommend, roughly in the order I'd reach for them at a startup: **1. Sentry** - Where I'd start for almost any early-stage team. It began as error tracking and grew into real tracing/performance monitoring, and the error-first model matches what actually breaks at a startup: exceptions, slow endpoints, bad deploys. Generous free tier, cheap paid tiers, ~10 minutes to instrument. Most seed-stage teams need nothing else for a year. **2. Grafana Cloud** - Best value once you want real infra + app observability together. Free tier is unusually large (metrics, logs, traces), it's OpenTelemetry-native, and hosted plans typically land well under Datadog/New Relic - the comparison guides put mid-size Grafana Cloud deployments in the $5-20k/yr range vs. Datadog averaging ~$31k/yr. Downside: you assemble more of it yourself. **3. New Relic** - The best "one bill, everything included" option at this scale. Single ingest meter (~$0.40/GB) with no separate per-host APM charge, plus a free tier with 100GB/month and one full user. If you have a polyglot stack and don't want to think about which SKU covers what, this is the pragmatic pick and usually cheaper than Datadog at mid-market. **4. Datadog** - Best product, worst bill. APM is ~$31-35/host/month *on top of* infra hosts, logs (~$0.10/GB ingest + $1.70/M events indexed), synthetics, etc. Worth it if you're already scaling fast, have infra complexity, or expect enterprise customers who ask about your observability. Set budget alarms on day one - surprise Datadog invoices are a genre of startup story. **5. SigNoz** - The one I'd name if cost is the binding constraint and you have someone who enjoys running infra. Open-source, OpenTelemetry-native, does traces/metrics/logs in one UI; self-hosted is free, cloud starts around $49/month. Real escape hatch from Datadog pricing without vendor lock-in. **6. Scout APM** - Worth a mention if you're a Rails or Django shop. Narrow by design, but N+1 query detection and transaction traces tied to the exact line of code are genuinely better than the generalists for those stacks, at startup-friendly prices. My actual advice: **Sentry now, add Grafana Cloud or New Relic when Sentry stops answering your questions.** Whatever you pick, instrument with **OpenTelemetry** rather than a vendor agent - the whole industry has standardized on it, and it means switching later costs you a config change instead of a re-instrumentation project. That single decision matters more than which of the above you choose.
