Peer review of Python software to support open science
We Run Software Peer Review
We review Python packages and software with the goal of helping scientists build better, discoverable and usable software.
Your package can also be published in JOSS through our review process.

Broadening participation in scientific open source
You don't need to be an expert to get involved
Are you new to software peer review but you want to get involved? We've got you! We offer support and mentorship to new reviewers completing their first review. All reviewers don't need to be python package experts. We welcome reviewers that focus on software accessibility and usability.
Are you new to peer review? We offer a mentorship program for anyone interested in participating in peer review but who might like a bit of support.
