Error tracking
Exception capture, grouping and alerting. 10 vendors tracked, 7 with a verified free tier.
Sentry
Sentry and Honeybadger both list 5,000 errors/month for one user; Honeybadger adds unlimited projects and 50 MB/day of performance & logs, which edges it for solo devs. Sentry wins on ecosystem. GlitchTip (1,000 events, unlimited projects) is the small Sentry-compatible fallback.
