Sourcery

Sourcery is an AI-powered code review tool that analyzes pull requests in GitHub and GitLab to identify bugs, summarize changes, and suggest security fixes.

Sourcery is an automated code review tool designed to analyze pull requests within GitHub and GitLab environments. It operates by scanning code changes to identify logic errors, missed edge cases, and security vulnerabilities. When a pull request is submitted, the tool generates a summary of changes, posts review comments, and offers specific code fixes that users can commit directly. It also provides a feature to automatically approve low-risk pull requests that contain no critical findings. The tool is compatible with all programming languages recognized by GitHub, such as Python, TypeScript, Java, Go, and Rust. Security measures include SOC 2 Type II compliance, and the platform does not use customer code to train its models.
