What does Jina do?
Jina is an AI QA engineer designed to review pull requests. It doesn't just scan code for patterns — it actually runs your application on each PR, executes targeted probes, and reports real bugs before you merge. It builds a context layer from your codebase, infrastructure, and past issues to understand how changes ripple through the system.
When a PR comes in, Jina traces impact paths through that context layer to identify the parts most likely to break. It then runs simulations and custom probes against staging or preview deployments. It filters out false positives, groups related failures, and presents a concise report with a merge score. Features include blast radius planning, root cause explanations, and hermetic sandbox execution for security.
Jina is built for engineering teams that want to catch bugs early without slowing down development. It's especially useful for complex systems where a small change can have unexpected side effects. Teams using CI/CD pipelines can integrate Jina to get automated, context-aware QA on every pull request.
