the engine is open source
the technology at the core of bldr — the distributed, content-addressed build system — is free and open. run the daemon on your own hardware, inspect every line, and never worry about lock-in. bldr cloud is orchestration on top, never a gate in front.
the whole build system
the content-addressed store, the block/ref layers, garbage collection and the pure dag runner.
the bldr cli and the daemon that owns the store, schedules pods and exposes the grpc api.
fs, blob, http, oci and pod functions — the deterministic building blocks of every build.
one daemon, one binary
start a node, register a workspace, and run your first cached build. the first run populates the cache; the next resolves entirely from content-addressed objects.
…and many more. see the full reference.
everything needed to build is open source and always will be. the proprietary layer is purely orchestration — the automation, collaboration and governance a fleet needs. you can run the core forever without ever paying us a cent.
built in the open
issues, patches and ideas are welcome. bldr is early software — the best time to shape it is now.
