Icelus

Describe a screen and it draws. Then edit it like Figma, with real buttons, fields and switches. Underneath, every screen is text on a character grid, so it pastes into a README or a chat and stays editable.

Free on the web, $0.99 on the App Store for iPhone, iPad and Mac.

Features

Say what a screen is for and it appears. Edit it on a canvas with 39 parts, auto layout, symbols and grids, or paint over it with brushes and masks. Link buttons to screens and press Play to click through it like a real app. Review flags overlaps, unlabeled fields and taps that are too small, and fixes what it can. When it's done, hand it off as React or SwiftUI code, a build brief for Claude Code, a PDF or plain text. 27 languages, no account needed.

Run

npm install && npm run dev
npm test

Agents get an API, an MCP server and a GitHub Action that fails a build when a wireframe box stops closing. See docs/API.md.
