Built different

Not another Rails monolith. GitBlixt is built from the ground up on the technology that powers WhatsApp and Discord.

Genuinely Fast

Built on the BEAM virtual machine. Elixir's lightweight process model handles thousands of simultaneous git operations, SSH connections, and webhook deliveries without breaking a sweat.

Truly Self-Hosted

Your code never leaves your infrastructure. No telemetry, no phoning home, no vendor lock-in. Deploy on a single server or scale across a cluster.

GitLab Compatible

Drop-in API compatibility with GitLab v4. Your existing tools, CI runners, and code review bots like CodeRabbit work from day one. No migration scripts needed.

Real-Time Everything

Built with Phoenix LiveView. Pipeline status, pull request discussions, and live log streaming update instantly over WebSockets. No polling, no page reloads.

Why GitBlixt?

Self-hosting GitLab means running a Ruby on Rails monolith that demands gigabytes of RAM just to idle. GitHub keeps your code on someone else's servers. Gitea is lightweight but limited.

GitBlixt takes a different approach: a focused, modern forge built on Elixir's concurrency primitives, with the API surface you already know.

  • Fraction of the resources — runs comfortably on a 1GB VPS where GitLab needs 8GB+
  • Existing tools just work — GitLab CI runners, code review bots, IDE integrations
  • Built for concurrency — BEAM processes handle I/O-heavy git operations without thread-pool contention
  • Hot code upgrades — deploy new versions without disconnecting active SSH sessions or WebSocket clients
  • Open source, MIT licensed — no "community vs enterprise" split, no features behind a paywall
