# Sentry

Canonical: https://inetgeek.com/observability/sentry/

Error monitoring and tracing sold per event across errors, spans, logs and replays, with a self-hosted build offered without support guarantees.

## Who it suits

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.

Consider something else if 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.

## What the documentation says

### Pricing

- Free tier: Yes ([source](https://sentry.io/pricing/), read 2026-09-06)
- Entry paid plan: $26/month for Team, the cheapest paid plan ([source](https://sentry.io/pricing/), read 2026-09-06)
- 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. ([source](https://sentry.io/pricing/), read 2026-09-06)
- When you exceed a cap: Billed, not throttled: each meter charges for additional usage beyond the included amount, at a published per-unit rate. ([source](https://sentry.io/pricing/), read 2026-09-06)

### Observability

- Events included: 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. ([source](https://sentry.io/pricing/), read 2026-09-06)
- 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. ([source](https://sentry.io/pricing/), read 2026-09-06)
- Session replay: Supported ([source](https://sentry.io/pricing/), read 2026-09-06)
- Self-hostable: Limited ([source](https://develop.sentry.dev/self-hosted/), read 2026-09-06)
