About Canary
Summary
Canary builds an AI QA engineer for software teams shipping code with AI coding tools. It reads source code directly to understand developer intent, then runs the application and attempts to break every change before it reaches production, replacing manual test writing and flaky DOM-scraping approaches. Engineering teams use it to catch broken user flows that AI-generated code introduces faster than traditional QA can handle.
Business model

Go-to-market
B2B engineering teams adopt Canary by installing it into their existing AI coding workflows with a single prompt, making it self-serve for developers already using tools like Claude, Codex, Cursor, or Copilot.

The first AI QA engineer that understands your code
AI coding tools have made developers 100x faster but customer-facing incidents are up 43% YoY, QA hasn't kept up. Canary is the first AI QA engineer that understands your codebase. Instead of relying on flaky DOM scraping or screenshot analysis, Canary reads your source code directly to understand developer intent and catch broken user flows before they hit production. Engineering teams go from weeks of manual testing to 90%+ coverage in days. Built by a team that built coding agents at Windsurf, Cognition and Google.
