Buddy Visual Tests

Every UI change, reviewed before merge

What it does

Not only can AI agents build your UI, they can now test what it actually looks like. Buddy Visual Tests captures every UI change, compares it pixel by pixel with an approved baseline, and brings visual regression testing straight into your delivery flow. With CLI, MCP and Skills support, agents can spot visual bugs, fix them, rerun tests, and hand over intentional changes for human approval.

Visual Tests capture snapshots of your rendered UI and compare them against approved baselines - so layout shifts, style drift, and missing elements get caught before they merge. Runs inside Buddy CI/CD, GitHub Actions, or locally. In Preview.

Agents change UI faster than anyone can open a browser. Buddy renders every change, diffs it against an approved baseline, and hands you, or your agent, the exact pixels that moved. Human or agent written, every change passes the same checkpoint before it lands. Buddy compares what the browser actually painted, not the code behind it. You get baseline and current displayed side by side, every difference outlined. Chrome, Firefox and Safari, light or dark, from HD desktop to iPhone, Pixel and Galaxy. Each variant resolves its own baseline, so a mobile-only regression can't hide behind a clean desktop. Set the diff threshold, or hand Buddy the CSS and XPath selectors for the parts that never…from buddy.works

    Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…

  • I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
