Sentry Alternatives
Sentry (sentry.io) has been the error-tracking leader since 2012. In 2024 pricing rose (from $26/mo to $80+ for small teams). Self-hosted version is open-source but heavy (needs Kubernetes + 8 GB RAM). Alternatives: GlitchTip (drop-in Sentry fork, lightweight), Rollbar, Bugsnag (Smartbear), Enterno.io for simple uptime+error monitoring. Datadog APM — enterprise alt.
Below: competitor overview, feature comparison, when Enterno.io wins, FAQ.

Frequently Asked Questions
Sentry vs file-based error logging?
File logs — history without alerting, manual triage. Sentry groups duplicates, alerts, shows stack trace + context. Must-have in prod.
Is GlitchTip really compatible?
Yes. Sentry SDK sends events to the GlitchTip endpoint without code changes. Open-source fork, lightweight.
Sentry + Enterno combo?
Recommended: Sentry for app errors + Enterno for uptime/SSL/security headers. Different layers of the stack.
When to upgrade Sentry free → paid?
When >5k errors/mo (one prod error per minute = 43k/mo). Or when you need >1 user.
