Projects using Hypothesis

The following is a non-exhaustive list of open source projects I know are using Hypothesis. If you’re aware of any others please add them to the list! The only inclusion criterion right now is that if it’s a Python library then it should be available on PyPI.

You can find hundreds more from the Hypothesis page at libraries.io, and thousands on GitHub. Hypothesis has over 8 million downloads per week, and was used by more than 5% of Python users surveyed by the PSF in 2023.
