bb

bb is an agentic development environment designed to let AI agents build, customize, and automate the environment they work inside. Users can control it through a desktop application, web interface, CLI, or HTTP API. Work is organized into live threads that people can monitor, steer, or hand off to another agent. The system uses provider CLIs that users already have authenticated instead of forcing a separate model account flow. Desktop builds are available for macOS, while Linux runs through npx and Windows is supported through WSL2. Its monorepo includes apps, packages, plugins, tests, and supporting development tools. The project is under active development, with a stable core architecture but still-evolving workflows and user surfaces.
