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

- Yes
- $26/month for Team, the cheapest paid plan

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.

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.

- Self-Hosted Sentry — Sentry Developer Documentation ↗
“In addition to making its source code available publicly, Sentry offers and maintains a minimal setup that works out-of-the-box for simple use cases. This version comes with no guarantees or dedicated support. Sentry engineers will do their best to answer questions and are dedicated to making sure self-hosted is running, but that's where our involvement ends.”
