In their own words
Comby
Comby is a free, open-source tool for searching and changing code structure with lightweight templates. It recognizes basic syntax in code, strings, and comments across many languages, with parsers listed for C/C++, C#, Go, Java, JavaScript, Python, Rust, Swift, and TypeScript, plus a generic matcher for other formats. The project targets large refactors and one-off changes, and an interactive review mode lets users inspect proposed edits. Comby can run from its command line, Python bindings, or HTTP requests sent to a server on your machine. Installation instructions cover macOS with Homebrew, Ubuntu, Windows through Ubuntu on WSL, and Docker; building from source is also described. Linked projects include an Emacs package and a prototype VS Code extension. Other uses include structural code search, compiler fuzzing, test-case reduction, editor find and replace, and academic research. Comby matches balanced delimiters while accounting for comments and string literals, and supports regex search. It is self-hosted and available for API, Linux, macOS, and Windows use. The Apache-2.0 license is identified in the public repository.
Sourcery
Sourcery reviews pull requests with AI, returning a summary, review comments and suggested fixes within minutes. Users can apply a suggestion as a change and commit it to the pull request. Security checks cover committed secrets, static-analysis vulnerabilities, infrastructure-as-code misconfigurations, dependencies and licenses. The extension works in VS Code, Cursor, Windsurf and JetBrains editors, and Sourcery supports GitHub, GitLab, GitHub Enterprise Server and self-hosted GitLab. Open Source checks security on every pull request; Open Source and Pro also scan twice a week, while Team includes nightly scans. The public REST API, for listing, reading, counting and bulk-updating security findings and groups, is a Team feature. Open Source is free; Pro is $12 a month billed annually, or $15 per developer per month billed monthly. Team is $24 a month billed annually, or $30 per developer per month billed monthly. A 14-day Team-feature trial is available organization-wide after installation, without a credit card. Sourcery says it does not retain customer code after reviews or use it to train models.
