CrashCartOpen-source error tracking

Point any Sentry SDK at CrashCart and it receives crashes, errors, messages and release-health sessions. One Go binary, one Postgres, nothing else.

What is CrashCart?

GitHub

🔌

Sentry SDK compatible

Keep the SDKs you already ship — iOS, Android, Flutter, React Native, web and backend. CrashCart speaks the envelope protocol; the viewer, API and data model are its own.

📦

One binary, one database

A single stateless Go binary and Postgres. TimescaleDB is optional; Neon, Supabase or RDS work too. Run it with Docker Compose in a minute.

🧭

Issue-centric viewer

Overview, issues grouped by fingerprint, stack traces, breakdowns by release / device / OS, release health with crash-free rates. Server-rendered, keyboard triage.

🧩

Symbolication built in

ProGuard / R8 and source maps resolve in-process. dSYMs through an optional sidecar. Upload with curl or sentry-cli.

🔔

Alerts

New issue, regression and crash-spike detectors per project, delivered to webhooks or Telegram.

🔁

Portable data

A versioned NDJSON export format shared by every CrashCart implementation. Back up, restore, or move between the Go and serverless editions.
