⬡ Building

Cairn — autonomous QA agent · Apache-2.0 Walks your app from a saved session, grounds every locator against the live page, designs cases per ISO/IEC/IEEE 29119-4, and generates self-repairing POM-style @playwright/test specs. Turns an OpenAPI 3.x spec into API tests too.

Plune — eval platform for LLM apps · MIT Assertion suites in one plune.yaml — run locally with the CLI, gate every pull request with eval-action, catch regressions with a diff.
