Reduce back and forth
code reviews

Code review cycle can go on for days. DeepSource flags issues within seconds after a pull request is created — enabling you to do the first review yourself rather than waiting for the reviewer.

Never miss a known bug to production

With DeepSource in place, have peace of mind that the issues detected by our analyzers are guaranteed to not end up in production.

Track metrics around
your codebase

Keep track of metrics like test coverage, documentation coverage, direct and indirect dependencies — to get a complete visibility of the state of the codebase. All metrics are updated realtime.

Quick to setup

Connect DeepSource with GitHub/GitLab, generate .deepsource.toml and auto commit the config directly to the repository to start analyzing your code. A single config file for all analyzers — from Python to Dockerfile.

Integrates with existing code review workflow

DeepSource is natively integrated with GitHub and GitLab. No extra setup or maintenance needed. The analysis runs on every commit and pull request and reports back issues and metrics.

Fewer false positives

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

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.

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
