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

Brands named, in the order the engine gave

1. Sentry mentioned
   Sentry - Start here if you're a small product team.
2. Grafana Cloud mentioned
   Grafana Cloud - Best value if someone on the team is comfortable with Prometheus/OpenTelemetry.
3. OpenTelemetry mentioned
   Grafana Cloud - Best value if someone on the team is comfortable with Prometheus/OpenTelemetry.
4. New Relic mentioned
   New Relic - The best "one tool, don't think about it" option on a budget.
5. APM mentioned
   No per-host APM tax, which matters a lot if you autoscale or run containers.
6. Datadog mentioned
   Datadog - but only via the startup program.
7. Honeycomb mentioned
   Honeycomb - Worth it specifically if you're debugging a distributed system with weird, hard-to-reproduce failures.
8. SigNoz mentioned
   SigNoz - The OpenTelemetry-native open-source option.
9. Sentry + Grafana Cloud mentioned
   Most startups under ~20 engineers: Sentry + Grafana Cloud, both largely on free tiers, which covers application errors and infrastructure for close to $0.

The answer, as recorded

## My short list, in the order I'd actually try them **1. Sentry** - Start here if you're a small product team. It began as error tracking and now does tracing, session replay, and logs, and it's the one tool where the output is usually a stack trace pointing at the line that broke rather than a dashboard you have to interpret. Free Developer plan (1 user, 5k errors/mo), Team at $26/mo with unlimited users. Event-based pricing means adding engineers doesn't cost more - a real thing at startup scale. Weakness: it's not an infra monitoring tool, so pair it with something else once you have hosts to watch. [sentry.io/pricing](https://sentry.io/pricing/) **2. Grafana Cloud** - Best value if someone on the team is comfortable with Prometheus/OpenTelemetry. The free tier is unusually generous and not a crippled demo: 10k metrics series, 50 GB logs, 50 GB traces, 14-day retention. You get metrics, logs, traces, and dashboards in one place, and because it's OTel/Prometheus-native you can leave later without re-instrumenting. Cost is setup time - it's more assembly than the others. [grafana.com/products/cloud/free-tier](https://grafana.com/products/cloud/free-tier/) **3. New Relic** - The best "one tool, don't think about it" option on a budget. 100 GB/mo ingest free forever, unlimited basic users, one full-platform user included; beyond that it's $0.40/GB. No per-host APM tax, which matters a lot if you autoscale or run containers. The trap is the full-platform user tier - $99/additional user on Standard, $349 on Pro - so watch how many people need deep access. [newrelic.com/pricing/free-tier](https://newrelic.com/pricing/free-tier) **4. Datadog - but only via the startup program.** It's the most complete platform and the one your future SRE hire will already know. At list price it's brutal for a startup: $31/host/mo for APM *on top of* $15/host for infra, plus $0.10/GB logs. But if you're Series A or earlier and new to Datadog, the startup program gives up to a year free and up to $100k in credits via a partner referral. Take the credits, and go in knowing you'll face a real bill at renewal. [datadoghq.com/partner/datadog-for-startups](https://www.datadoghq.com/partner/datadog-for-startups/) · [datadoghq.com/pricing](https://www.datadoghq.com/pricing/) **5. Honeycomb** - Worth it specifically if you're debugging a distributed system with weird, hard-to-reproduce failures. Its high-cardinality querying and BubbleUp answer "which customers on which build in which region" in a way the others struggle with. Free tier is 20M events/mo; Pro starts at $150/mo for 50M. Overkill for a monolith with three services. [honeycomb.io](https://www.honeycomb.io/blog/we-listened-simpler-pricing-youre-welcome) **6. SigNoz** - The OpenTelemetry-native open-source option. Self-host for free (you pay in infra and ops time) or Cloud from $49/mo with no per-host and no per-user fees. Pick this if you have strong data-residency requirements or a platform engineer who'd rather own the stack. Don't pick it to save money if nobody has time to run it. [signoz.io/application-performance-monitoring](https://signoz.io/application-performance-monitoring/) ## What I'd actually do Most startups under ~20 engineers: **Sentry + Grafana Cloud**, both largely on free tiers, which covers application errors and infrastructure for close to $0. If you'd rather pay for one thing that does everything, **New Relic**. If you can get the **Datadog** startup credits, take them - just set a calendar reminder three months before they expire to model the real bill. Two things to avoid: per-host pricing if you run containers or autoscale (it's how the horror-story invoices happen), and anything that isn't OpenTelemetry-compatible - instrument with OTel and switching vendors stays cheap. One caveat on the numbers: I verified every price above against the vendors' own pricing pages, since the "APM comparison" sites that dominate these search results are mostly affiliate content with stale figures.
