If you are using CircleCI* and it is configured to archive your artifacts, getting started with BuildSize is easy! Just add the GitHub App to your repo and that's it! All artifacts will be automatically monitored.
* Support for other CI systems coming soon
If a pull request significantly increases the size of any of your build artifacts, BuildSize will automatically set a build status, and optionally post a comment to the PR.
BuildSize is open source, so you can do whatever you want with it. Contribute some bug fixes, or even run your own version.
