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. Slack mentioned
   Dead-simple SDK install, and the stack trace lands in Slack with the offending line highlighted.
3. Grafana Cloud mentioned
   Grafana Cloud - The best "won't regret it in two years" choice.
4. OpenTelemetry mentioned
   Built on Prometheus and OpenTelemetry, so your instrumentation is portable and you have essentially no vendor lock-in - the single most expensive mistake teams make with observability.
5. Datadog mentioned
   Generous free tier, and hosted plans typically run well below Datadog or New Relic.
6. New Relic mentioned
   Generous free tier, and hosted plans typically run well below Datadog or New Relic.
7. you're mentioned
   Datadog - Excellent product, genuinely the best UI and breadth in the category, and I'd name it if you're past ~Series B or already on a sprawling AWS footprint.
8. AWS mentioned
   Datadog - Excellent product, genuinely the best UI and breadth in the category, and I'd name it if you're past ~Series B or already on a sprawling AWS footprint.
9. SigNoz mentioned
   SigNoz - Worth naming if you're cost-sensitive and have someone who enjoys running infrastructure.
10. Sentry + Grafana Cloud mentioned
    Then: Sentry + Grafana Cloud if you want cheap and portable, New Relic alone if you want one vendor and no fuss, Datadog when you can afford it.

The answer, as recorded

## What I'd actually pick, in order **1. Sentry** - Start here. For most startups the bugs you ship are a bigger problem than your p99 latency, and Sentry's error tracking plus tracing and session replay covers both at the lowest cost of anything in this space (typical annual spend $1k-$10k, with a usable free tier). Dead-simple SDK install, and the stack trace lands in Slack with the offending line highlighted. It's not a full APM - no deep infra metrics - but for a pre-Series A team it's the highest value per dollar. **2. Grafana Cloud** - The best "won't regret it in two years" choice. Built on Prometheus and OpenTelemetry, so your instrumentation is portable and you have essentially no vendor lock-in - the single most expensive mistake teams make with observability. Generous free tier, and hosted plans typically run well below Datadog or New Relic. The tradeoff is you assemble more of it yourself; expect to spend a day or two on dashboards rather than getting them handed to you. **3. New Relic** - The most startup-friendly pricing of the big incumbents: 100 GB/month free ingest, then $0.40/GB, with free basic users and only $10-99 for full platform seats. If you want real APM - distributed tracing, DB query breakdowns, host metrics - with zero assembly required and a bill that stays near zero pre-Series B, this is it. Watch the per-seat costs as the team grows; Pro seats jump to ~$349/user/year. **4. Datadog** - Excellent product, genuinely the best UI and breadth in the category, and I'd name it if you're past ~Series B or already on a sprawling AWS footprint. But it's priced for companies that aren't you yet: $15/host/month for infra plus $31/host/month for APM, and a 20-host startup with APM and logs realistically lands at $2,500-$5,000/month. The bill scales faster than your headcount does. **5. SigNoz** - Worth naming if you're cost-sensitive *and* have someone who enjoys running infrastructure. Open source, OpenTelemetry-native, self-hostable, and explicitly aimed at teams outgrowing basics but balking at Datadog pricing. Free if you run it yourself; the cost is engineer-hours, which at a startup are not actually cheap. ## The short version Instrument with **OpenTelemetry** from day one regardless of which you choose - that's what makes switching later a config change instead of a rewrite. Then: **Sentry + Grafana Cloud** if you want cheap and portable, **New Relic** alone if you want one vendor and no fuss, **Datadog** when you can afford it.
