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

Brands named, in the order the engine gave

1. Sentry mentioned
   For most startups: Sentry first, then add Grafana Cloud or New Relic when you need real tracing/metrics.
2. Grafana Cloud mentioned
   For most startups: Sentry first, then add Grafana Cloud or New Relic when you need real tracing/metrics.
3. New Relic mentioned
   For most startups: Sentry first, then add Grafana Cloud or New Relic when you need real tracing/metrics.
4. Datadog recommended
   Don't start with Datadog unless someone else is paying.
5. OpenTelemetry mentioned
   Free tier is genuinely usable (10k series, 50GB logs, 50GB traces), it's OpenTelemetry-native, and the self-host escape hatch means you're never hostage to a renewal quote.
6. Honeycomb mentioned
   Honeycomb - Worth naming specifically if you're already distributed and debugging "it's slow for some users" problems.
7. SigNoz mentioned
   SigNoz (or Uptrace) - The self-hosted OTel-native option.
8. Instrument mentioned
   - Instrument with OpenTelemetry, not vendor SDKs.

The answer, as recorded

Searched - here's what I'd actually recommend, roughly in the order I'd consider them. ## The short answer For most startups: **Sentry first, then add Grafana Cloud or New Relic when you need real tracing/metrics.** Don't start with Datadog unless someone else is paying. --- **1. Sentry** - Start here, almost regardless of stack. It's error tracking first and APM second, which matches what actually breaks at a startup (exceptions and bad deploys, not p99 latency on a 40-service mesh). Five-minute SDK install, ties stack traces to the commit and PR that caused them, and the free tier covers a small team. Source pins it as "best for product teams and startups prioritizing dev velocity." If you only ever buy one thing, buy this. **2. Grafana Cloud** - Best value once you need metrics + logs + traces properly. Free tier is genuinely usable (10k series, 50GB logs, 50GB traces), it's OpenTelemetry-native, and the self-host escape hatch means you're never hostage to a renewal quote. Typical paid spend lands ~$5-20k/yr vs. Datadog's ~$30k average. Cost is a steeper learning curve - you're assembling Prometheus/Loki/Tempo/Pyroscope rather than getting one polished pane of glass. **3. New Relic** - The most startup-friendly *single-vendor* free tier: 100 GB/month ingest free forever plus one full user. Ingest-based pricing (~$0.40/GB) with no separate per-host APM charge, which is why it usually comes out cheapest at mid-market scale. Pick this over Grafana if you'd rather have one integrated product than glue four together. **4. Datadog** - The best product, and the one that will quietly eat your seed round. APM is ~$31-35/host/mo *plus* separate meters for logs ($0.10/GB ingest + $1.70/M events indexed), synthetics, RUM, etc. Right answer once you have real infra complexity and a budget line for observability; wrong answer at 3 engineers and a Rails monolith. **5. Honeycomb** - Worth naming specifically if you're already distributed and debugging "it's slow for *some* users" problems. High-cardinality querying is genuinely better than everyone else's for that class of bug. Overkill for a monolith. **6. SigNoz** (or Uptrace) - The self-hosted OTel-native option. Free as in "you pay for servers and your own time." Pick it if you have infra-minded people and a hard cost ceiling; skip it if nobody wants to own a ClickHouse cluster at 2am. --- **Two things that matter more than the choice:** - **Instrument with OpenTelemetry, not vendor SDKs.** Every tool above ingests OTel. Do this and switching vendors is a config change instead of a quarter of work - which is your real protection against the renewal-quote problem. - **Sample your traces.** Cited as the single biggest cost lever: 5-10% sampling cuts trace spend ~90% with no practical loss in debuggability. **Sources:** - [APM for Startups (2026): Grafana Cloud vs New Relic vs Datadog Free Tier](https://performance.qa/blog/apm-tools-compared/) - [APM Pricing 2026: Datadog vs New Relic vs Dynatrace vs AppDynamics](https://monitoringcost.com/apm-pricing-comparison) - [Datadog vs New Relic vs Grafana: What Companies Actually Spend on Observability](https://www.cledara.com/blog/datadog-vs-new-relic-grafana-observability-spending) - [We Tried & Compared Top 6 Open Source APM Tools in 2026 - SigNoz](https://signoz.io/blog/open-source-apm-tools/) - [Best 16 Application Performance Monitoring Tools & Software 2026 - Uptrace](https://uptrace.dev/tools/top-apm-tools)
