The answer, as recorded

# Best APM for startups My actual short list, in the order I'd recommend it: **1. Sentry** - Start here if you're pre-Series A. It's error tracking first, tracing second, and for most startups errors *are* the performance problem you actually need to fix. Instrument in ~10 minutes, get stack traces with the offending line and release attribution. Free Developer plan is 5K errors + 10K spans/month with 30-day retention; Team plans start ~$26/mo. Caveat: it's not infra monitoring - no host metrics, no dashboards for your Postgres. **2. Grafana Cloud** - Best value if you want real observability (metrics + logs + traces) without a bill that scales with your ambition. The free tier is genuinely generous: 10K metric series, 50GB logs, 50GB traces, 3 users, 14-day retention. It's OpenTelemetry-native, so you're never locked in - instrument once, repoint later. Cost of that flexibility is setup time; it's more assembly than Datadog. **3. New Relic** - The most startup-friendly pricing of the big commercial APMs: 100GB/month free, then per-user consumption pricing. If you want one vendor covering backend, frontend, and mobile with auto-instrumentation and don't want to build anything, this is the lowest-effort "grown-up APM." Watch the per-full-user seat cost as the team grows - that's where it bites. **4. Datadog** - Best product in the category, and I'd only reach for it once you have infra worth monitoring and revenue to justify it. Expect real money: ~$23/host infra + ~$40/host APM + $0.10/GB logs, which lands a 20-host startup around $2.5-5K/month. Don't adopt it at seed stage; the bill surprises are legendary. **5. SigNoz** - The one to know if you're cost-sensitive but want a single unified pane. Open-source, OTel-native, ClickHouse-backed; self-host free or use Cloud at $49/mo base + ~$0.30/GB. Good escape hatch from Datadog pricing if you have someone willing to own it. **Honorable mentions:** Honeycomb if you're debugging high-cardinality distributed systems (BubbleUp is genuinely differentiated, free tier is 20M events); Better Stack if you want logs + uptime + on-call incident paging in one simple tool. **What I'd actually do:** Sentry from day one, add Grafana Cloud when you have more than a couple of services, and only evaluate Datadog/New Relic when someone's full-time job is reliability.
