A Rosetta Stone for UI component libraries

In plain words

Frontfamily is a tool that maps UI components and props across eight popular component libraries including MUI, Chakra UI, Ant Design, and Bootstrap. It contains 1,258 hand-verified component mappings with behavioral notes to guide accurate conversions between frameworks. The tool runs entirely in the browser without sending code elsewhere, offering deterministic conversions through a website interface and CLI tool for developers migrating between UI library ecosystems.

From the sources

Deterministic component conversion between MUI, Chakra UI (v2, and v2 → v3 upgrades), Ant Design, EUI, Mantine, Bootstrap, Tailwind (via Headless UI components), and Quasar. 1673 component + prop mappings with behavioral notes. Runs in your browser — no code sent anywhere.

1673 component + prop mappings across 7 UI libraries — with behavioral notes for the gotchas a rename can’t capture. Deterministic conversion, file in / file out, and every conversion is a shareable URL. No AI, no hallucinated props, no code leaving your browser. Same input, same output, every time. Every mapping is a fixed rule you can read and diff — no model, no guessing. Runs entirely in your browser. Nothing is sent to a server. Safe for proprietary code. Behavioral differences are flagged, and components that aren’t in the mapping table are listed as unmapped instead of guessed at. Every conversion gets a report: each prop that passed through unmapped, was dropped, or needs review, by…from frontfamily.com

  Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!

  For a year or two I've been building a UI library with the aim of making desktop applications fun and easy to write. It is currently written in C/Ruby and uses a custom tree sitter grammar to describe templates. Features include: composable UI components, template directives, event and prop handling, slots, styles and automation capabilities baked in. One of the goals of the project is privileging easy to write custom components via a drawing API over providing a fixed set of components. At the time of this writing it should install on Windows, Mac, and Linux, but sometimes it is hard…

  Clipto MCP▲655

  Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

  Simple algorithm and color space to generate diverse skin tones▲627

  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…
