Own your errors. Own your stack. A fully open-source, self-hosted error tracking Rails engine — a free Sentry alternative that runs entirely inside your own process, with no external services and zero recurring cost. Captures what SaaS tools charge extra for: local and instance variables at the moment of failure (via TracePoint), exception cause chains, swallowed-exception detection, breadcrumbs, and system-health snapshots (GC, memory, threads, connection pool, Puma). Plus N+1 query detection, storm protection (a circuit breaker that shields your app from error floods, ON by default), multi-app support, error sampling, and async logging via Sidekiq, SolidQueue, or GoodJob. Runs on SQLite, PostgreSQL, or MySQL/Trilogy — in your app's existing database or an isolated separate error database. Beautiful dashboard UI (dark/light), multi-channel notifications (Slack, Email, Discord, PagerDuty, webhooks), workflow management, advanced analytics, platform detection (iOS/Android/Web/API), and two-way issue sync with GitHub, GitLab, Codeberg, and Linear. Also: LLM observability, AI-powered debugging help, and OpenTelemetry span export. 5-minute setup, works out-of-the-box. Rails 7.0-8.1, Ruby 3.2-4.0. BETA: API may change before v1.0.0.
