ripgit

A self-hostable git remote backed by Cloudflare Durable Objects. One DO per repo, SQLite storage, FTS5 search, delta compression via xpatch. Built in Rust with workers-rs.

Live example: git.theagents.company — deathbyknowledge's repos including agents (~1k commits) and curl (~40k commits)

git remote add origin https://your-worker.workers.dev/username/myproject
git push origin main

Features

• Standard git remote — git push, git clone, git fetch with any git client
• Auth via Service Binding — sits behind an auth worker; public read, owner-only write. GitHub OAuth example in examples/github-oauth/
• Agent-first UI — browsable pages also negotiate text/markdown and text/plain, with explicit actions and curl-friendly paths
• Web UI — file browser, commit history, diffs, code search, syntax highlighting, branch selector, markdown README, repo settings
• Full-text search — FTS5 over file content and commit messages. Supports @author:, @message:, @path:, @ext:, @content: query prefixes
• Raw file serving — /:owner/:repo/raw/:ref/*path
• Read API — refs, commits, trees, files, diffs, search, stats
• Repo registry — repos listed on the owner profile page after first push
• Delta compression — 5–20x compression on real repos depending on file churn
• One DO per repo — strict isolation, scales horizontally

URLs

/:owner/                   owner profile — lists your repos
/:owner/:repo/             repo home — file tree, README, recent commits
/:owner/:repo/commits      commit history
/:owner/:repo/commit/:sha  commit detail with diff
/:owner/:repo/tree/:ref/*  directory browser
/:owner/:repo/blob/:ref/*  file viewer
/:owner/:repo/raw/:ref/*   raw file bytes
/:owner/:repo/search-ui    full-text search
/:owner/:repo/settings     stats, index rebuilds, config, delete (owner only)

API

All endpoints under /:owner/:repo/.

Text Mode For Agents

Browsable pages support negotiated text mode for curl, scripts, and agents.

curl -H 'Accept: text/markdown' https://your-worker.workers.dev/alice/repo/
curl -H 'Accept: text/plain' https://your-worker.workers.dev/alice/repo/commits
curl 'https://your-worker.workers.dev/alice/repo/tree/main/src?format=md'

• Accept: text/markdown returns a markdown view
• Accept: text/plain returns the same content as plain text
• ?format=md or ?format=text works when you can't keep headers attached while following links
• Text pages list bare GET paths under headings like Files (GET paths) and spell out POST actions, fields, and requirements in an Actions section

Authentication

ripgit reads identity from trusted X-Ripgit-Actor-* headers, which are only settable by an upstream auth worker via Service Binding (not from the public internet).

• Anonymous — read access to all repos
• Authenticated — read + write to repos under your username

GitHub OAuth example

examples/github-oauth/ is a TypeScript Cloudflare Worker that authenticates with GitHub, issues session cookies for browsers and long-lived tokens for agents/scripts, and forwards requests to ripgit via Service Binding. Its landing page and /settings also support the same text-mode negotiation for curl-driven agents.

See examples/github-oauth/README.md for a focused deploy/setup guide.

Local dev:

cd examples/github-oauth
npm install
npm run dev:full   # auth worker on :8787, ripgit as service binding

Visit http://localhost:8787 → sign in → go to /settings → create a token → push:

git remote add origin http://username:TOKEN@localhost:8787/username/myrepo
git push origin main

First-time setup:

1. Create a GitHub OAuth App — callback URL: http://localhost:8787/oauth/callback
2. Set GITHUB_CLIENT_ID in examples/github-oauth/wrangler.toml
3. wrangler secret put GITHUB_CLIENT_SECRET
4. wrangler secret put SESSION_SECRET
5. wrangler kv namespace create OAUTH_KV → fill IDs into wrangler.toml

Deploy:

wrangler deploy                          # ripgit worker
cd examples/github-oauth && wrangler deploy   # auth worker

Update the GitHub OAuth App's callback URL to your deployed auth worker URL.

Push test script

./scripts/push-test.sh -u username -t TOKEN -w https://your-worker.dev -r /path/to/repo

Setup (ripgit only, no auth)

Prerequisites: Rust, wrangler, LLVM (for zstd-sys).

brew install llvm
git clone https://github.com/your-org/ripgit
cd ripgit
wrangler kv namespace create REGISTRY   # fill ID into wrangler.toml
wrangler deploy

Without the auth worker in front, all repos are publicly readable and writable by anyone with the URL.

Architecture

Auth Worker  (examples/github-oauth — optional, recommended)
  │  validates session/token, sets X-Ripgit-Actor-* headers
  │  Service Binding

ripgit Worker  (entry, routing)
  │  /:owner/:repo/* → DO named "{owner}/{repo}"
  │  /:owner/        → profile page (queries REGISTRY KV)

KV namespaces:
  REGISTRY  — "repo:{owner}/{repo}" written on first push
  OAUTH_KV  — tokens, sessions (auth worker only)

Pushing large repos

Cloudflare Workers has a 100 MB request body limit. Push large repos incrementally:

./scripts/push-test.sh -u username -t TOKEN -r /path/to/repo -s 200

Or manually in checkpoints:

STEP=250
for FP in $(seq $STEP $STEP $(git rev-list --first-parent --count main)); do
  SHA=$(git rev-list --reverse --first-parent main | sed -n "${FP}p")
  git push origin "${SHA}:refs/heads/main"
done
git push origin main

Known limitations

• DO storage timeout — pushes with >~10K objects per push can exceed the 30 s timeout; push incrementally
• 100 MB request body limit — hard Workers platform constraint
• No force push — may produce inconsistent state
• No annotated tags — silently dropped; lightweight tags work
