Visual Site Builder
Visual site builder for React & Next.js teams
Design with your real components on an infinite canvas. Edit code visually. Ship pull requests instead of static mockups. Built for teams that already own a React codebase.
What a visual site builder should be
Most visual site builders are walled gardens. You drag, you drop, you publish — and the moment you need to do anything serious, you hit the wall: no real components, no design system, no git, no PR review, no hosting your own way.
Weblab flips it. The canvas reads your real React code. The components on the left panel are the ones already in your repo. The colors are your tokens. The output is a pull request to your GitHub repository — reviewable by engineers, mergeable on your schedule, deployable to your infrastructure.
Designers get a visual surface. Engineers keep code as the source of truth. Everyone ships the same artifact.
How it works
Step 1
Connect your repo
Point Weblab at a React or Next.js GitHub repository. We parse your components, design tokens, and routes. Nothing leaves your repo unless you ship a PR.
Step 2
Design on canvas
Drag your real components onto an infinite canvas. Adjust spacing, swap variants, tweak tokens visually. AI suggestions are constrained to what already exists in your design system.
Step 3
Ship a pull request
When the design is ready, hit "Open PR". Weblab writes a clean diff against your codebase. Engineers review it in GitHub like any other PR. Merge to deploy.
How it compares
| Capability | Weblab | Hosted drag-and-drop builders |
|---|---|---|
| Uses your real components | Yes — reads your existing React/Next.js codebase | No — generates the platform’s own markup |
| Output | Pull request to your GitHub repo | Hosted page on the platform |
| Design system aware | AI is constrained to your tokens and components | Generic components and styles |
| Hosting | You own it — Railway, Vercel, your VPS, anywhere | Locked to the platform (or risky one-time export) |
| Code ownership | Code lives in your repo from day one | Code lives on the vendor — export is an escape hatch |
| Open source | Yes — self-host for free | No |
| Built for teams | Designer + engineer workflow with PR review | Mostly solo / freelance designer workflow |
Built for
Design engineers
Skip the handoff. The artifact you design IS the code that ships. Visual canvas with a code source of truth.
Frontend teams
Cut weeks from the design-implement-review loop. Designers edit the real components, engineers review the diff in GitHub.
Founders + small teams
Iterate on UI as fast as you can on a whiteboard. Own the code from day one. No vendor lock-in.
Design system owners
Your tokens, your components, your rules. The visual editor enforces the system instead of letting people drift around it.
Agencies
Hand clients a real codebase, not a hosted page they have to migrate out of later. Ship custom React sites at the speed of drag-and-drop.
Solo product builders
Move from concept to deployed page without leaving the canvas or babysitting a framework you'd rather not touch by hand.
Visual site builder
FAQ
A visual site builder lets you compose a website on a canvas instead of editing markup by hand. Weblab is a visual site builder for teams that already have a React or Next.js codebase — you design with your real components, and the changes ship as a pull request to your repo.
Drag-and-drop builders generate their own markup and host the result on their platform. Weblab works on your real codebase: it reads your components and your design tokens, lets designers and engineers edit them on an infinite canvas, and writes the diff back to GitHub as a PR. You keep ownership of the code and the hosting.
Yes — Weblab is built for React and Next.js codebases. If you're starting from zero, we recommend bootstrapping a Next.js app first. For non-React codebases, the visual builder still works for design exploration but the PR output targets React/JSX.
Yes. Designers see an infinite canvas with real components and tokens. Developers see the underlying JSX/TSX. Changes are bidirectional — moving a card on the canvas updates the code, and editing the code updates the canvas.
Yes — you can self-host Weblab from GitHub. The hosted cloud version is available with a Free tier and paid Pro tiers on the pricing page.
Weblab reads whatever lives in your repo: shadcn/ui, Material UI, Chakra UI, Radix, Tailwind tokens, CSS modules, styled-components. The AI is constrained to your real components and tokens — it won't invent new ones unless you ask it to.
Yes — you can pull frames from Figma and have Weblab translate them into your real components, then refine on the canvas. The output is JSX backed by your design system, not a new component tree.
Free for self-hosting. The hosted cloud version has a free tier with daily message limits and paid Pro tiers from $25/month upward. See the pricing page for the full grid.
