Free Figma Alternative — Online UI Design & Prototyping
A complete Figma-class interface design tool that runs entirely in your browser: frames, vector networks, boolean ops, components with overrides, auto-layout, and interactive prototyping. Nothing is uploaded — your design files stay on your own device.
FigCraft
Interface design and prototyping - frames, components, and vectors - a Figma-class editor in your browser.
First launch downloads ≈9 MB, then it's cached for a year. Nothing is uploaded — your files stay on this device.
This is a desktop-class app — it works best on a larger screen.
Quick Answer
This free online design tool gives you the core Figma workflow in a browser tab: frames and artboards, vector networks with boolean operations, reusable components with overrides, auto-layout that resizes responsively, styles, and clickable prototyping links you can share. It runs as a GPU-composited WebAssembly canvas on your device — design files are never uploaded to any server.
How It Works
Open and Launch — Open the design tool page in a desktop browser and click Launch. The first launch downloads about 9 MB; after that it is cached.
Set Up Frames — Create frames for your target devices and lay out a first screen with shapes and text.
Build Components — Turn repeating elements into components, override per instance, and use auto-layout for responsive stacks.
Prototype and Export — Wire clickable prototyping links between frames, then export assets as PNG, SVG, or PDF.

Frequently Asked Questions
Is this really free, and do I need an account?
Yes — completely free, no account, no watermarks. The underlying software is open source under Apache-2.0, embedded exactly as published.
Are my designs uploaded anywhere?
No. The whole tool runs as WebAssembly inside your browser tab; everything you draw, edit, and export happens on your device.
Can it open Figma files?
It is a standalone editor with its own document format — it does not read .fig files. For existing Figma assets, export SVG or PNG from Figma and import those here.
Can I collaborate with other people in real time?
Real-time multiplayer needs a coordination server, which this privacy-first embedding does not run. Design locally and share exported assets, or hand off .svg/.pdf files.
Does it work on mobile?
It runs on modern mobile browsers, but precision design work wants a desktop screen, a mouse, and keyboard shortcuts. View prototypes on a phone after exporting.
