Motion Debugger: open-source browser critic that flags visual bugs for AI coding agents

A developer posted Motion Debugger on Hacker News, an open-source workflow for coding agents. According to the snippet, it uses Chromium to inspect a rendered site and catch broken animations, overlapping elements, layout issues, and other visual problems. It then gives the agent feedback so it can fix those problems. The snippet says a/b tests are included in the repository.

AI-assisted summary based on the listed source.

Built a tool to unslop UI and add cool motion. It's an open-source workflow for coding agents, using Chromium to inspect the rendered site, catch broken animations, overlapping elements, layout issues, and other visual problems, then gives the agent feedback to fix them. a/b tests are in the repo.

Developers using AI coding agents to build front-end interfaces may find a visual feedback loop useful, since the agent gets concrete reports on rendering problems rather than relying only on code. Teams should watch whether the project's A/B test results hold up on real sites and how it performs across different frameworks and designs.
