title: 'Rules'
---

The Bazel ecosystem has a growing and evolving set of rules to support popular
languages and packages. Much of Bazel's strength comes from the ability to
[define new rules](/versions/7.4.0/extending/concepts) that can be used by others.

This page describes the recommended, native, and non-native Bazel rules.

## Recommended rules {:#recommended-rules}

Here is a selection of recommended rules:

* [Android](/versions/7.4.0/docs/bazel-and-android)
* [C / C++](/versions/7.4.0/docs/bazel-and-cpp)
* [Docker/OCI](https://github.com/bazel-contrib/rules_oci){: .external}
* [Go](https://github.com/bazelbuild/rules_go){: .external}

The repository [Skylib](https://github.com/bazelbuild/bazel-skylib){: .external} contains
additional functions that can be useful when writing new rules and new
macros.

The rules above were reviewed and follow our
[requirements for recommended rules](/versions/7.4.0/community/recommended-rules){: .external}.
Contact the respective rule set's maintainers regarding issues and feature
requests.

## Native rules that do not apply to a specific programming language

Native rules are shipped with the Bazel binary, they are always available in
BUILD files without a `load` statement.
