Builder-web - a web frontend for reproducible builds

Builder-web takes in submissions of builds, typically from builder, and displays the produced artifacts in a way that makes it easy to compare checksums and build status. Produced binaries can be downloaded and executed. itself runs builder-web.


Builder-web is a single binary web server using a sqlite3 database with versioned schemas. Finished builds from builder are uploaded to builder-web, stored and indexed in the database and presented in the web interface to the user. Users can:


Installing from source can be done with opam: opam install builder-web.

We also provide reproducible binary packages.


Builder-web consists of a binary builder-web that runs a web server on port 3000 listening on all interfaces by default. These values can be changed with the --port and --host flags respectively. See builder-web --help for more information.

Service scripts for FreeBSD and systemd are provided.

The web server expects a sqlite3 database in its data directory. An empty database can be created with builder-db migrate.

Database migrations

The sqlite3 database builder-web uses contains versioning information. On every schema change the database schema version is updated, and migration and rollback scripts are provided. The tool for database migrations is builder-migrations. See the builder-migrations --help output for each migration for further details.
