A true developer tool for designers, helping you code without knowing anything about code.
Design, code, and AI in one canvas. What you move on screen is the file you ship.
Start buildingReference images, designs, and docs in chat. AI sees what you see, with no more explaining from scratch.
Drag, resize, and arrange elements directly on the canvas. See changes appear in real code instantly.
Edit components in a proper editor with syntax highlighting and multi-file tabs. Every visual change writes back into the file you'd ship.
Reuse your existing design system: buttons, cards, navs. Live components, not screenshots.
Manage posts, pages, and collections in one tidy panel. Edit a field and the canvas updates — no separate dashboard, no copy-paste.
A live tree of your DOM. Click any node to jump to it on the canvas, with no inspector hunting.
Every save is a version. Branch, restore, and compare without leaving the canvas.
Switch between leading models as you need. Pick the one that fits the task.
Install, build, test, and deploy from your own terminal. No lock-in, no black box.
Colors, type, spacing — defined once, used everywhere. Edit a token, every component follows.
Weblab is a visual design canvas that connects to your existing codebase. Designers drag real components onto an infinite canvas, make changes visually, and submit pull requests, with no coding required.
Traditional design tools create static mockups that must be rebuilt in code. Weblab works with your real components, so what you design IS the code. Changes become PRs, not handoff specs.
AI generators create new code from scratch. Weblab constrains AI to YOUR existing components, so outputs match your design system. No translation, no drift.
No. Designers use a visual canvas with familiar tools. Real code runs underneath, so you don't need to touch it unless you want to.
Yes. Weblab ships a static-HTML scaffolder for landing pages, portfolios, and marketing sites — no framework required.
Yes. Hit "Start blank" to scaffold a fresh project, then use the AI chat in the editor to generate pages, sections, and styles. No existing codebase needed.
Yes. The desktop app loads your local codebase and runs alongside your AI coding agent — design visually in Weblab while Claude Code does the heavy lifting in your terminal. Codex, Cursor, and Gemini support is rolling out.
Yes. Share your canvas, leave spatial comments, and work together in real-time. Changes sync to code and can be submitted as PRs for engineers to review.
React, Next.js, and any CSS approach (Tailwind, CSS modules, styled-components). Works with any component library.
Yes. Weblab is open source under Apache 2.0 — self-host the whole thing free from GitHub. The hosted cloud version has a free Basic plan with daily AI credits, plus paid plans for unlimited AI and custom domains.
The code you make with Weblab is all yours. Export it locally, publish to GitHub, or deploy to a custom domain.
