The idea is to connect test results and artifacts with commit history and testing environment. This way test reports can show whether a failure in a pull request is a real regression or a known flake from a target branch.
The core of the service is a specialized analytics engine that makes it possible to store and query large amounts of test results [1]. Thanks to this engine, we've processed 2.5 billion test results to date.
Flakiness.io is used already by a few large open sources (nuxt/nuxt [2], wordpress/gutenberg [3]). There's a 1GB free plan which is enough for roughly 10M+ test results, and I'd be happy to increase this limit to 100GB for large open source projects upon request.
Let me know what you think about the project!
