Aspect was founded by Bazel experts who believe the ecosystem succeeds when tooling is open, composable, and well-maintained. We publish and maintain a large portfolio of open-source Bazel rulesets and tools — and we think carefully about how to sustain that work.

​
Our projects

See Open Source Projects under the Bazel section for a full listing of the rulesets, tools, and examples Aspect maintains, organized by language and category.

​
Contributing

We welcome contributions across all of our open-source repositories. Most repositories include a CONTRIBUTING.md with project-specific guidelines. General notes:
  • Bug reports and feature requests — open an issue on the relevant GitHub repo.
  • Pull requests — include a description of the problem, the approach taken, and any test coverage. We review against the compatibility matrix and supported Bazel versions documented in each repo.
  • Questions — the Aspect community Slack is the best place for open-ended discussion.

​
Prioritization

Aspect uses a tiered framework to prioritize open-source work — from active engagement customers down to community contributions, with exceptions for ecosystem-critical changes. See Open Source Development Prioritization for the full framework.

Support

Need more than community support? Aspect offers commercial Bazel support via a dedicated Slack channel with guaranteed response times.
