Requires PHP 8.5+, Composer, Bun, and PostgreSQL 17+ with pgvector and pg_trgm. Create a devnull database, then:
git clone https://github.com/dev-null-sh/dev-null.sh.git
cd dev-null.sh
composer setup
composer devRun composer test before opening a pull request.
Pages hear about changes through any server speaking the Pusher protocol, such as Laravel Cloud's WebSockets or a self-hosted Reverb. By default BROADCAST_CONNECTION=log sends nothing anywhere and every page polls as before. To try them locally, run a Pusher-protocol server on your machine, set BROADCAST_CONNECTION=reverb with the REVERB_* variables pointing at it, set the matching VITE_REVERB_* variables, and rebuild the assets: the VITE_ ones are read at build time. Tests always use the null broadcaster.
In production, the server needs BROADCAST_CONNECTION=reverb and the REVERB_APP_ID, REVERB_APP_KEY, REVERB_APP_SECRET, REVERB_HOST, REVERB_PORT and REVERB_SCHEME of the WebSocket server, and the build needs VITE_REVERB_APP_KEY, VITE_REVERB_HOST, VITE_REVERB_PORT and VITE_REVERB_SCHEME. A queue worker must be running, since updates for more than a hundred people at once go through the queue. Each person's own channel is authorized by /broadcasting/auth (signed requests for the apps); the channels for commits, profiles, the log, headlines and features are public and carry ids only.
Commits are attributed to people only: never add Amp, Claude Code, or any other AI tool as a co-author, and keep their names out of commit attribution (author, committer, and trailers).
Amp runs .agents/setup to prepare a reusable snapshot with PHP 8.5, Composer, Node 26, the Bun version from package.json, locked dependencies, generated routes, and built assets. Setup also prepares isolated PostgreSQL 18 development and test databases with vector and pg_trgm, including extensions inherited by parallel test databases. It is safe to rerun and preserves an existing .env and application key.
Run amp orb services ensure to start the supervised database and app and print the app's portal URL. The app uses the existing local sign-in flow (any handle, no GitHub credentials required). Frontend assets are prebuilt; rerun bun run build after frontend edits. No resume hook is needed: Amp supervises the services, and dependency installation belongs only in setup.
The database is loopback-only and uses trust authentication and relaxed durability for disposable development data. Do not use this configuration for production.
