New Relic

New Relic's permanent free tier gives startups full platform access up to 100GB/mo of ingest with no credit card required — the most generous and risk-free starting point of the three.

What it does well
  • Free tier is permanent and includes full platform access — not a watered-down feature set — up to 100GB/mo ingest
  • No credit card required to start, with usage-based pricing only kicking in past the free cap
  • Standard tier scales gradually: $10/mo for a second full-platform user, $0.40/GB beyond 100GB
Watch out for
  • Per-core-user pricing ($49/core user) can add up for teams needing many full-platform seats
  • Smaller third-party integration ecosystem than Datadog's broader partner network

Grafana Cloud

Grafana Cloud is a hosted observability platform built on the open-source Grafana stack, with a free-forever tier and metered usage-based pricing above that.

What it does well
  • Free tier is explicitly free forever — 10k active metric series, 50GB each of logs/traces/profiles, 14-day retention, 3 users, no credit card
  • Built on the open-source Grafana project, giving a self-hosting escape hatch if a startup wants to avoid vendor lock-in later
  • Pro tier's $19/mo platform fee is a low entry point before usage-based overages apply
Watch out for
  • Pro tier pricing is platform fee plus metered usage, not a flat price — costs can climb with scale
  • Less deep cross-product correlation between infra, APM, and logs than Datadog's tightly integrated platform
Best For Startups that want open-source flexibility and a genuinely free starting tier with no time limit.

Datadog

Datadog is an infrastructure monitoring and APM platform with usage-based, per-host pricing and a narrow free tier limited to basic infrastructure monitoring.

What it does well
  • Unifies infrastructure monitoring, APM, log management, and security in one platform with deep cross-product correlation
  • Large third-party integration ecosystem covering most cloud and infrastructure tooling
  • Pro and Enterprise infrastructure tiers ($15–23/host/mo) are competitively priced for infra-only monitoring
Watch out for
  • Free tier is narrow — capped at 5 hosts with only 1-day metric retention, easy for a growing startup to outgrow immediately
  • APM has no free tier at all and starts at $31/host/mo bundled, or $36/host/mo standalone
Best For Startups that have scaled past free-tier limits and want the broadest unified observability ecosystem.

Frequently Asked Questions

What's the best APM tool for a startup with no dedicated DevOps team? +

New Relic — its free tier includes full platform access up to 100GB/mo with no credit card required, so a small team can get real observability without setup overhead or upfront cost.

Is Datadog too expensive for an early-stage startup? +

It can be. Datadog's free tier is capped at just 5 hosts with 1-day retention, and its APM product has no free tier at all, starting at $31/host/mo. New Relic and Grafana Cloud both offer more generous free starting points.

Which tool is best if a startup wants to avoid vendor lock-in? +

Grafana Cloud, since it's built on the open-source Grafana project. A startup can start on the free-forever hosted tier and self-host the same open-source stack later if it wants more control.
