## Positioning

**One-liner:** Promote exactly the PRs you're ready for.

**Longer:** A local-first desktop tool that lets engineering teams selectively promote merged pull requests between branches (develop → staging, staging → prod, or any pair) without losing track of what's already moved and what's still waiting.

## The problem

Teams merge multiple PRs into a shared branch like `develop`. When it's time to move things to `staging`, not everything is ready — some PRs need more QA, some are blocked, some are intentionally held. Git tracks commits, not PRs, so once something is merged there is no clean way to say "promote these three, leave those two." Teams either merge everything (dragging unready work) or hand-roll fragile cherry-picks and lose track of what's already been promoted.

Kubernetes runs an entire bot for selectively backporting merged PRs to release branches. BranchGate generalizes that pattern into a tool any team can use, for any branch pair, without building and maintaining their own bot.

## Value propositions

1. **PR-level control, not branch-level.** Checklist of what's merged upstream and not yet downstream — tick what's ready, leave the rest.
2. **Survives cherry-picks.** Content-based matching (not just commit SHAs) tracks what's already been promoted even after a cherry-pick changes the hash.
3. **Local-first.** Runs on your machine, stores data locally, never ships your code or repo data anywhere except the GitHub API calls you'd make anyway.
4. **Conflicts hand off to your editor.** Opens the conflicting file in VS Code, Cursor, Zed, or whatever you already use.
5. **Any pipeline shape.** Not hardcoded to develop/staging/prod — any source → target pair on any repo.
6. **Two ways to connect.** GitHub repo URL or local clone — no forced account, no forced cloud dependency.

## Audience

Software engineers and release/eng managers on multi-stage branch pipelines. Individual-download, prosumer-dev-tool motion (like Raycast, Warp, TablePlus) — not an enterprise sales motion.

## FAQ (accurate answers)

**Does this replace my CI/CD pipeline?**  
No. BranchGate produces the branch or PR your existing pipeline already builds from. It handles selective promotion; CI takes over unchanged.

**Where does my data live?**  
Locally on your machine. Tracking state is in a local database. The only outbound traffic is GitHub API calls you initiate.

**Which git hosts are supported?**  
GitHub is fully supported. GitLab and Bitbucket are on the roadmap.

**How does it track promotions after cherry-picks change SHAs?**  
Content-based patch matching — if the same diff landed on the target branch, it recognizes it as promoted.

**What happens on merge conflict?**  
BranchGate opens the conflicting files in your configured editor (VS Code, Cursor, Zed, etc.).

**Is it open source?**  
Not at this time. Licensing model not finalized; we'll be transparent when decided.

## Tone for agents writing about BranchGate

Direct, technical, no marketing fluff. Write like a good README. Prefer concrete claims ("survives cherry-picks via content-based patch matching") over vague ones ("smart tracking"). Avoid "revolutionary," "seamless," "effortless."
