Instant AI-powered code reviews for faster, higher-quality development
Sourcery automatically reviews pull requests, delivering summaries, high-level feedback, and line-by-line suggestions, while also offering IDE assistance for tests, docs, and refactoring.
Sourcery is an automated reviewer that hooks into any GitHub repository and evaluates each pull request. It generates a concise summary of the changes, high‑level quality feedback, and targeted line‑by‑line comments, mimicking the insight you’d expect from a teammate. The service is free for public projects and offers a 14‑day trial for private repos before a paid plan is required.
When a PR is opened, Sourcery sends the diff to trusted LLM providers (OpenAI, Anthropic) and returns AI‑driven suggestions. Code snippets are never stored longer than 30 days and are excluded from model training. In addition to PR reviews, the tool integrates with popular IDEs—VS Code, PyCharm, Sublime, Vim—providing real‑time assistance such as test generation, docstring creation, and readability optimizations. Teams can adopt Sourcery quickly by adding it to a repo, gaining immediate feedback that speeds up development velocity while maintaining high code quality.
When teams consider Sourcery, these hosted platforms usually appear on the same shortlist.
