What Canary does
Canary is an AI QA engineer that understands your codebase. It reads source code to understand what an app is supposed to do, then tests it like a real user would, catching broken user flows before they reach production rather than relying on flaky DOM scraping or screenshot analysis.
Key capabilities
- Reads pull requests and source code to understand developer intent
- Analyzes code diffs, generates feature and regression tests, and runs them against a preview app
- Runs tests in real browsers in parallel and posts results in the PR
- Reports passed and failed tests with video recordings for every failure
Who it's for
Canary targets engineering teams that want fast, reliable test coverage tied to their actual code, helping them move from weeks of manual testing toward high automated coverage in days. It has caught issues such as broken auth flows and slow page loads. The company is built by ex-Google and Windsurf engineers and is part of Y Combinator's W26 batch.
