# Sentry vs SigNoz

Canonical: https://inetgeek.com/compare/sentry-vs-signoz/

Every value below is read from Sentry's and SigNoz's own documentation. See https://inetgeek.com/methodology/ for how.

## At a glance

| Criterion | Sentry | SigNoz |
| --- | --- | --- |
| Free tier | Yes | No |
| Entry paid plan | $26/month for Team, the cheapest paid plan | $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 | 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. | 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 | 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. | 15 days by default for logs and traces, selectable up to 30, 90, 180 days or 1 year at higher rates. |
| Self-hostable | Limited | Supported |

## Which should you choose?

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.

Consider something else: 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.

Consider something else: SigNoz — $0.30 per GB is six times OpenObserve's rate, so a high-volume log pipeline pays a large premium for the packaging.

## Documented by only one

- When you exceed a cap: Sentry: Billed, not throttled: each meter charges for additional usage beyond the included amount, at a published per-unit rate.
- Events included: Sentry: 50,000 errors a month on Team and Business; 5,000 on Free. Errors are one meter of several — logs, spans, replays and uptime monitors are counted and billed separately.
- Session replay: Sentry: Supported
- Ingest price per GB: SigNoz: $0.30 per GB ingested for logs, and the same for traces. Retention is chosen per signal and priced with it.
