What is Blop?

Editorial review
Blop is a QA agent designed for engineering teams that use coding agents to ship software. It allows teams to define end-to-end tests in plain English, which are then executed by an agent driving a real browser via Playwright. Crucially, these tests live as version-controlled code (.blop.ts files) directly within your GitHub repository, ensuring transparency, reviewability, and ownership, rather than being hidden in a vendor dashboard. The platform integrates seamlessly with existing CI/CD pipelines, such as GitHub Actions, and provides features like automatic failure clustering and synthetic monitoring. Blop's agent can even auto-fix broken tests by opening pull requests to update selectors when the UI changes, verifying the fix before team review. This approach aims to reduce the toil of test maintenance, allowing QA to keep pace with rapid development cycles.
