AI agents explore multiple solutions to every PR problem, show you side-by-side trade-offs, and iterate with you until the best option ships — not just comments, real working alternatives.
undiff appears in your PR like a GitHub bot, but under the hood multiple specialized agents analyze features, coverage, security, and visual changes in parallel.
Instead of one AI chatbot, undiff spawns specialized agents simultaneously — one for feature logic, one for test coverage, one for security, one for visual regressions. Each returns focused, actionable feedback.
For UI changes, see before/after screenshots from your real app — not just code. Pixel-level comparison of what actually changed in the browser.
See changes organized by feature, not by file. Understand what each PR actually does at a product level — "added dark mode toggle" instead of "modified 14 files".
Dedicated agent for XSS vectors, insecure dependencies, leaked secrets, and OWASP patterns — tuned for frontend codebases.
Push code as usual. undiff hooks into your GitHub workflow automatically.
Multiple AI agents analyze your changes in parallel — features, coverage, security, visual.
Results organized by context, not files. Visual diffs, coverage maps, security flags — all inline.
Address findings, re-run agents, merge. Every PR ships with full context.
Other tools chat about code. undiff understands it in context.
Inside the undiff GitHub bot on your PR, propose multiple implementation options for functional or visual improvements. Each option runs in its own isolated environment, executes tests, generates visual output, and returns a side-by-side report with clear pros and cons.
