Models can pass every test in today's benchmarks and still write React that fails in production. Tests verify behavior, but they miss React performance, accessibility, and quality issues. ReactBench holds solutions to a higher bar than just passing tests: every solution must pass held-out behavioral tests and produce no new React Doctor issues. Broken effects, unnecessary renders, accessibility problems, and maintainability issues can fail code even when its tests are green. Tasks span 50+ open-source React repositories: realistic changes grounded in existing projects, not synthetic puzzles. Read the blog post and explore the results. Task types - Write React : implement a real feature or fix mined from a merged pull request. The agent receives the base repository and an issue-style instruction; the reference patch and verifier are withheld. The verifier injects hidden fail-to-pass behavior tests, and a pinned React Doctor scan compares the submission against the base commit. Any new graded issue fails the task. - Fix React : recognize and refactor React problems from source code alone. The agent must remove every target React Doctor finding without introducing another graded issue, and the task's own test suite must still pass. React-aware linters are stripped from the agent image; only the verifier contains the pinned scanner and its clean baseline.
