Buildbot is a continuous integration and release automation framework written in Python. It lets you achieve software builds, unit tests, packaging, and deployment in a highly configurable, distributed manner, and it is known for being able to run complex build and test farms across many platforms from a single master.

Key Features

• Master/worker architecture — a central build master orchestrates many worker machines for parallel builds.
• Highly configurable — defined entirely in Python, giving unlimited flexibility for unusual workflows.
• Multi-VC support — works with Git, SVN, Mercurial, Perforce, and other version control systems.
• Flexible triggers — builds on commit, schedule, nightly, or triggered by other builds.
• Web interface — the Nine UI provides Grid, Waterfall, Console, and Build views of build status.
• Notifications — alert on build results via email, IRC, or webhooks.
• Step & result tracking — detailed logs, timeline of steps, and result summaries per build.
• Cross-platform workers — run workers on Linux, Windows, macOS, and other systems.

Why Use Buildbot?

Buildbot shines when you need full control over a complex, distributed build and test farm, such as testing a project across many operating systems and compiler versions simultaneously. Its Python-defined configuration is powerful for teams whose pipelines don’t fit simple YAML templates.

Use Cases

• Cross-platform build and test farms (Linux, Windows, macOS, BSD) from one master.
• Continuous integration for large C/C++, Python, and other multi-compiler projects.
• Automated release and packaging pipelines with fine-grained control.
• Research and embedded projects that need reproducible matrix builds.
