FAQ

  • Is GlitchTip a drop-in replacement for Sentry?

    Yes. GlitchTip speaks the Sentry SDK protocol, so you can point your existing Sentry SDKs at a GlitchTip instance without changing any code. Just update the DSN URL.

  • Is GlitchTip really free?

    Yes. GlitchTip is MIT licensed and 100% free when self-hosted. There are no per-seat limits, no event quotas, and no enterprise-only features. Their managed cloud service starts at $15/month.

  • Why is Sentry no longer open source?

    Sentry switched from BSD to the Business Source License (BSL) in 2019. The BSL allows source code access but restricts production use for competing services. It converts to Apache 2.0 after 4 years.

  • Can GlitchTip handle the same volume as Sentry?

    For error tracking, yes. GlitchTip uses PostgreSQL and Redis — the same stack millions of Django apps run on. For very high volume (100K+ events/hour), Sentry's ClickHouse backend may scale better, but most teams will never hit that ceiling.

  • Does GlitchTip support React Native / Flutter / Electron?

    GlitchTip is compatible with any Sentry SDK. If Sentry has an SDK for your platform, it works with GlitchTip. Currently tested platforms include JavaScript, Python, Django, Go, PHP, Ruby, Rust, React Native, and .NET.

  • How do I migrate from Sentry to GlitchTip?

    Change your DSN (Data Source Name) URL from sentry.io to your GlitchTip instance URL. No code changes required. If you need to migrate historical data, use GlitchTip's import tools or Sentry's data export API.

  • What are Sentry alternatives?

    GlitchTip is the best open-source alternative. Others include: Highlight.io (session replay focused), OpenReplay (self-hosted session replay), and SigNoz (OpenTelemetry native). Each has different strengths.
