Error Monitoring
Best Sentry Alternatives & Open-Source Competitors in 1970
Sentry is priced as per-event volume + seats, starting at $26/mo (Team, 50,000 errors). Here are 3 alternatives, with their pricing, self-hosting effort and trade-offs.
Why teams move away from Sentry
- Event and seat pricing climbs quickly for teams and noisy apps
- Self-hosting is heavy: Kafka, ClickHouse, Snuba and workers to operate
- The self-hosted licence is source-available (FSL), not OSI open source
