Vaka

Vaka is a self-hosted crash reporting and analytics service built for coding agents.

• Crash reporting: errors and crashes grouped into issues, symbolicated (JS source maps, Android R8, iOS dSYM, native/Rust debug info), with breadcrumbs, regressions and crash-free users/sessions per release.
• Web and mobile analytics: cookieless, no-PII visitor counts, pageviews, screen views, referrers, UTM tags, devices and countries.
• Product analytics: custom events with properties, breakdowns by any property.

There is no dashboard. A small admin UI (/ui) handles setup: users, projects, keys and tokens. Everything else goes through the REST API or the MCP server, so you can ask an agent "what broke in yesterday's release and why?" and let it fix the bug.

Start here

• Quickstart: run Vaka and send a first event in five minutes.
• Self-hosting: configuration, storage, backups and upgrades.
• Install an SDK: JavaScript, Android, iOS, Rust, or any language over HTTP.
• Connect an agent: MCP. Machine-readable index: /llms.txt.
