Composal is an AI testing tool that sends browser agents into your web product to act like real users and find what breaks before your customers do. You start by giving it your product URL and, if you like, connecting sources such as GitHub, Sentry, PostHog or Notion so it has a better idea of what the product is supposed to do. It then launches a group of agents that work through your key user flows and odd edge cases at the same time. Each run comes back with a video, logs and clear reproduction steps for anything that failed, and you can pass those steps to your coding agent through the CLI so it can fix the issue.
