Facts

What it does: Bazel is an open-source tool for building and testing software across languages and platforms.bazel.build · 30 Sept 2026
Incremental builds: Bazel caches previous work and rebuilds only what needs to change.bazel.build · 30 Sept 2026
Parallel execution: Bazel can run builds in a highly parallel and incremental fashion.bazel.build · 30 Sept 2026
Build language: Projects define build targets in BUILD files using Starlark, a domain-specific language.bazel.build · 30 Sept 2026
Languages and platforms: Bazel supports multiple languages and can build outputs for multiple platforms, including desktop, server, and mobile.bazel.build · 30 Sept 2026
Supported operating systems: Bazel runs on Linux, macOS, and Windows.bazel.build · 30 Sept 2026
Scale: The documentation says Bazel can handle builds with 100,000 or more source files and work across multiple repositories.bazel.build · 30 Sept 2026
Caching: Teams and continuous integration systems can share build outputs through a remote cache, which requires a separately chosen and maintained backend server.bazel.build · 30 Sept 2026
Security consideration: The remote cache can contain binaries, so the documentation says it needs to be secured and advises limiting who can write to it.bazel.build · 30 Sept 2026
IDE integrations: The official IDE integration page lists plugins for IntelliJ, Android Studio, CLion, and Visual Studio Code, plus integration options for Xcode.bazel.build · 30 Sept 2026
Install method: Bazelisk is the recommended installation method for Ubuntu Linux, macOS, and Windows.bazel.build · 30 Sept 2026
Support: The documentation points users to community support channels including Slack and Stack Overflow, as well as an issue tracker.bazel.build · 30 Sept 2026
Package support limits: The installation page says packages for several distributions and package managers are community-supported and not officially supported by the Bazel team.bazel.build · 30 Sept 2026
Governance: The Bazel project is led and managed by Google, with contributors and some community-managed components.cr.bazel.build · 30 Sept 2026
Purpose: Bazel is an open-source tool that automates software builds and tests.bazel.build · 30 Sept 2026
Parallel execution: Bazel can run build commands in parallel on the same computer or on remote build nodes.bazel.build · 30 Sept 2026
Languages: Bazel supports languages including C++, Java, Kotlin, Python, Go, and Rust.bazel.build · 30 Sept 2026
Mobile targets: Bazel can build software for Android and iOS.bazel.build · 30 Sept 2026
Extensibility: Users can write custom Bazel rules and macros in Starlark, a language that is a subset of Python.bazel.build · 30 Sept 2026
Reproducibility: Bazel can run builds and tests hermetically through sandboxing to minimize skew and improve reproducibility.bazel.build · 30 Sept 2026
CI integration: Bazel returns a non-zero exit code when a build or test invocation fails, supporting basic CI integration.bazel.build · 30 Sept 2026
Security-related feature: Bazel actions can run in individual sandboxes, and builds can be configured to run hermetically.bazel.build · 30 Sept 2026
Support: The project directs users to its discussion group, GitHub issue tracker, Slack, and Stack Overflow.bazel.build · 30 Sept 2026
Notable limitation: The FAQ says Bazel is not well suited to build operations whose outputs should not be cached, such as deployment steps that change cloud configuration.bazel.build · 30 Sept 2026
Intended projects: Bazel is especially suited to large codebases, projects using multiple compiled languages, multi-platform deployments, and projects with extensive tests.bazel.build · 30 Sept 2026
Maker: Google identifies Bazel as its own build tool.opensource.google · 30 Sept 2026
