• Startups: Sentry free tier sufficient
• Enterprise: Bugsnag, Rollbar rarer
• Self-host: GlitchTip emerging (more restrictive open-source Sentry fork)

FAQ

Q: Sentry vs Datadog?

A: Sentry better dev DX for errors + performance. Datadog full-stack observability. Often complementary.

Q: AI Autofix really useful?

A: For simple bugs, yes. Complex business logic errors: still needs review. But accelerator for standard stack traces.

Q: Self-host Sentry?

A: Possible but heavy (Postgres + ClickHouse + Redis). GlitchTip lighter if self-host critical.

Conclusion

2026 Sentry remains dev-friendly error monitoring standard. Session Replay + AI Autofix + Profiling broaden scope. For Africa startups, generous free tier sufficient MVP. Self-host via GlitchTip if data sovereignty critical. Datadog Error Tracking alternative if already Datadog client.
