JJHub

A Jujutsu-native overlay on GitHub

Projects a change, stack, and operation model onto GitHub's branches and PRs. GitHub keeps hosting, review, and CI; JJHub keeps the layer GitHub has no vocabulary for — stable change IDs that survive a rewrite, and platform-wide undo.

  • Stable change IDs across rewrites
  • Stacked PRs with automatic restacking
  • Platform-wide undo
  • MCP server for coding agents

Our Values

What we believe

The principles that guide everything we build

Transparency

Every action is logged, every decision is traceable. We build systems that show their work.

Reliability

Built on proven infrastructure patterns. Our tools are designed for production workloads.

Developer First

We build tools for engineers, by engineers. Great DX is not optional.

Open Standards

Kubernetes, OpenAPI, OpenTelemetry. We embrace open standards and avoid lock-in.
