What developers say

"DeepSource actually helped us resolve more than 50 bugs, which has made the code base much more stable and dependable. It allowed us to identify many more areas for improvement."

Piero Molino, Senior Research Scientist

"Making DeepSource part of our CI pipeline gives us confidence that, in particular, incoming code changes do not introduce additional issues."

Lewis McGibbney, NASA Jet Propulsion Laboratory

"DeepSource is static code analysis for humans. Stop wasting your time setting up and maintaining CLI tools on CI, just use DeepSource"

Ruslan Kuprieiev, Senior Software Engineer

Autofix Developer Preview

In addition to detecting issues, DeepSource can now suggest fixes for some of the commonly occurring issues and creates pull request with the fixes. Avoid the grunt work fixing the same issue across multiple files, manually.

Autofix is in developer preview — we're steadily increasing the coverage of issues.
