Quack AI

Quack AI is an open-source AI developer tool that turns team contribution guidelines into in-IDE code checks.

Quack AI turns engineering standards from documentation and pull requests into contextual assistance inside the IDE. Maintainers curate guidelines regarding naming, error handling, and testing by parsing existing documents and past pull requests. The extension pulls relevant guidelines for open files, checks diffs, and generates compliant code before review. Maintainers track broken rules to refine guidelines over time. The system runs on local LLMs through Ollama and allows complete self-hosting on your own infrastructure. Although the product is now sunsetted, the codebase remains available under the Apache 2.0 license on GitHub.
