fluid

What it does

Ask any AI agent to build a UI and you get the same site: Inter, a purple gradient, default shadcn, pure black. It's not a taste problem, it's convergence. fluid is 6 open-source skills (MIT) that push back: a committed identity per brief from a curated database, a house motion language, and a deterministic 23 rule slop detector that runs with no API call. The work ships looking like a studio made it, not a template. Works with Claude Code, Cursor, Codex, Gemini, and more.

Open-source agent skills: a unique brand identity per brief, liquid motion, and a deterministic guardrail against generic AI slop.

Your agent scaffolds a UI in seconds. fluid gives it a unique brand and motion that actually moves. Client work shipped on this system. The rules stay constant, every identity is its own. The same machine, every time. Here is one of our own products, Vigie, running through it, start to live. Fresh briefs, each one a full landing page rendered in its own DNA. Same rules, no two alike. "Landing page for Cohort, real-time product analytics for data teams. Precise, fast, trustworthy. Graphite-navy with a rationed cobalt accent. General Sans + Switzer, numbers in mono. Hero with a live dashboard, a logo strip, three features, a dark stats band." "Landing page for Coastline, slow coastal stays.…from fluid.plrstudio.fr

  Trickle - Magic Canvas 2025 · trickle.so · ▲1,064

  Hey HN! Introducing Trickle Magic Canvas: the world’s first Agentic Canvas, where you can visually co-create apps and websites with AI, from idea to production. Why is a canvas better? Most AI tools today rely on linear chats or text prompts. We believe that limits creativity and clarity. Canvas changes the game. 1. Every version & page at a glance. Each page and sub-page lives on a timeline. You can quickly browse, edit, and preview progress like a living, visual document — no more digging through chat logs or scattered states. 2. The canvas is the context. Unlike linear chats, you can…

  Mesa – A collaborative canvas IDE built for agent-first developmentMar 2026 · getmesa.dev · ▲16

  Hi HN - I'm Ryan a product designer who codes, and I built Mesa. Current IDEs feel wrong for the type of development being done now - the focus is still on files. Mesa puts the focus on the full workflow: your agent, terminal, browser, and files all live as equal nodes on a canvas with full multiplayer support. (think figma but for code) I was tired of the overhead of switching windows, tabs, and terminals across multiple projects. Inspired by TouchDesigner and Factorio, I wanted something more fluid and visual. Been using it as a total replacement for Cursor at work every day now. Being…

  Performative-UI – A react component library of design tropes▲1,181

  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!
