Sentry vs SigNoz
A comparison of Sentry and SigNoz built from values read directly from each provider's own documentation, with the source recorded against every figure.
The short answer
- Pick Sentry if
- Teams that want tracing, logs, replays and uptime in one place and will pay per meter for it. The tooling is the deepest in the category and the SDK coverage is the widest.
- Pick SigNoz if
- Teams that want per-GB billing without per-host or per-seat charges, and the option to run the same product themselves rather than being locked to the cloud version.
5 sourced criteria separate them:
- Free tier
- Sentry: Yes
- SigNoz: No
- Entry paid plan
- Sentry: $26/month for Team, the cheapest paid plan
- SigNoz: $49/month for Teams, and the $49 is usage credit rather than a fee on top — SigNoz bills against it before charging more.
- Pricing model
- Sentry: A plan fee plus five independent meters — errors, logs, application metrics, tracing spans and session replays — each with its own included amount and its own overage. Logs and metrics overflow at $0.50/GB; extra uptime alerts at $1.00 each.
- SigNoz: Per GB ingested, with no per-user, per-host or custom-metric pricing — SigNoz states all three exclusions explicitly. Retention is a per-signal choice that changes the rate.
- Retention window
- Sentry: 30-day lookback on Developer, the free plan. Up to 90 days on Team, and up to 90 days plus additional sampled retention on Business. Enterprise is custom. "Up to" is Sentry's own wording — the 90 days is a ceiling, not a guarantee.
- SigNoz: 15 days by default for logs and traces, selectable up to 30, 90, 180 days or 1 year at higher rates.
- Self-hostable
- Sentry: Limited
- SigNoz: Supported

Consider something else if…
- Sentry: Five meters bill independently, so 50,000 errors is not 50,000 units of observability. A team watching cost needs to watch spans and logs too, not just the error count.
- SigNoz: $0.30 per GB is six times OpenObserve's rate, so a high-volume log pipeline pays a large premium for the packaging.
