Jelly UI, Osmo, and Meng To’s three.js masterclass

This week: Osmo goes GA for GTM video teams, Jelly UI brings soft-body physics to native HTML forms, and Meng To open-sources a Three.js demo that Replit turned into a designathon.

Osmo went GA this week for GTM teams who need polished video without a motion designer. Jelly UI hit Hacker News with soft-body physics for native HTML checkboxes. Different tools, different problems, and both actually worth your attention.

Osmo launched general availability on August 5th. It generates video animations as editable code rather than fixed AI output, so you can change text, timing, colors, and brand rules after the fact without burning the asset down. The founding team came from A24, NBC, and Saturday Night Live. They raised $5M from Bain Capital Ventures. Positioning: "Canva accessibility, Adobe power."

Whether that holds up in practice is a different question. Video for GTM teams is a real problem, and Osmo is building for people who need polished storytelling without a production budget. The more interesting question is whether this carves out a durable category or gets absorbed by Canva or Adobe before it has the chance to find out.

Jelly UI hit the Hacker News front page and made the internet feel briefly more alive. It is a zero-dependency Web Components library that puts soft-body physics on native HTML form controls: sliders squish, toggles jiggle, checkboxes settle with a wobble. WCAG AA, dark mode, RTL support, 40 custom elements. The comments debated whether it should exist.

It should. The web does not have to feel like it was assembled from the same six UI libraries. Someone spent real time proving that native form controls can feel alive, and that matters regardless of whether Jelly UI ships in a production app this week.

Then there is Kage, Meng To’s Kyoto mountain temple, built in three.js and now open-sourced. Five scroll chapters, fog and rain and lanterns rendered live, under 1MB of JavaScript. It got 258K views on X this week. Replit built a designathon around it. If you do any three.js work at all, or just want to understand what a portfolio piece looks like when someone really tries, the repository is at github.com/MengTo/kage.

Framer is sitting at a $2B valuation and targeting $100M ARR, with 50% user growth this year. That kind of number changes what investors think the design tool market is worth and how much runway the next Osmo gets to prove itself. The category is growing up.
