# Sentry

Error tracking with a free Developer plan, a $26 Team plan and a self-hostable server under a source-available licence.

88 points out of 100. #1 of 12 error monitoring tools. Vendor: Functional Software, Inc. (Sentry). Website: https://sentry.io/

- The Developer plan is free and includes 5,000 error events a month with 30 days of history [1].
- Team costs $26 a month when billed annually and includes 50,000 error events and up to 90 days of history [1].
- SAML single sign-on needs the Business plan, listed at $80 a month [1][12].
- The server code uses the Functional Source License, not an open-source licence, and converts to Apache 2.0 after two years [10].
- Sentry names a SOC 2 Type 2 report and an ISO 27001 certificate [11].

Verdict: Sentry suits small teams that need SDKs for most languages and mobile platforms, with a free plan to start and a $26 paid plan [1][2]. You can choose US or EU storage and run the server yourself [9][13]. The catch: the server licence is source-available, not open source, and SAML sign-in costs $80 a month on Business [1][10][12]. Best for: Small teams that want wide SDK coverage and the option to self-host.
