About comber
comber automates end-to-end quality assurance for web applications by simulating user interactions on preview deployments. It operates without requiring test scripts, instead exploring every reachable state of an application like a real user would. The tool runs in CI pipelines, executing on each preview deploy to identify broken clicks, server errors, failed requests, and accessibility issues before users encounter them. Findings are delivered with detailed repro steps, screenshots, and traces, enabling quick debugging. comber uses a DOM-first approach for efficiency, resorting to vision-based checks only when necessary, and provides deterministic replays for cost-effective validation. It supports both self-hosted CLI usage with a provided Anthropic or OpenAI key and a managed option where the service runs the crawl on its infrastructure.
