Fits right in your existing code review workflow

DeepSource is natively integrated with GitHub, GitLab and Bitbucket. No extra configuration or maintenance needed. The analysis runs on every pull request, and reports back issues. Resolve them before the code is merged.

Highly relevant results with context-aware analysis

Our analyzers understand your code's context and avoid any false positives. If something slips by chance, report to us and we'll patch it soon — we take each report very seriously.

Everything you need to know about the issue

All information about errors detected is good. With DeepSource, you get to know more than just title and line number, such as category, occurrence path, when was it last-first seen, and description with possible solution for the issue.

Resolved critical security issues in Python.

"DeepSource has enabled us to significantly improve the quality of our Python codebase. Security is a big deal. When we know that we have no security issues and that we have the green light it is an excellent measure of project health.
