Cogniheim Web Builder
Build pages by hand.
Keep the Tailwind you get.
Drag components onto a canvas, set each style with a control that writes one real Tailwind class, then export HTML or React code that is yours.
How it works
- 01
Drag components
Pull boxes, headings, text, buttons, images, links and inputs onto the canvas, or tap to add on touch screens.
- 02
Set each property
One control writes exactly one Tailwind class. Pick a value and see the class it produces.
- 03
Preview three widths
Check mobile, tablet and desktop. Edits at tablet and desktop write md: and lg: overrides.
- 04
Export what you built
Copy HTML or a React component, or download a ZIP with every page and image.
What you get
- Real Tailwind classes
- The canvas runs Tailwind itself, so what you see is the class list you export.
- Breakpoint overrides
- Edit base, md: or lg: values separately. Empty fields show the inherited class.
- Drag and drop
- Move elements on the canvas or in the layers tree, with a clear drop indicator.
- Version history
- The last 20 versions of each page are kept. Restoring never deletes anything.
- Private by default
- Projects belong to your account. Nobody else can open them.
- Clean code export
- Readable HTML and JSX with all text escaped. No editor markup in the output.
Start from a template

An empty page.

Security and privacy
- Everything is encrypted in transit with HTTPS.
- Projects are private to your account.
- You must verify your email before you can create projects.
- The canvas and preview run in a sandboxed frame that cannot reach your session.
- There is no third-party analytics or tracking.
Questions
Do I own the code I export?
Yes. Exports are plain HTML, JSX or a ZIP. There is no runtime you have to keep.
Can I publish my site here?
Not yet. Today you build, preview and export. Publishing is not part of this release.
Which Tailwind version does it use?
Tailwind CSS v4. Exported full pages load a pinned copy with an integrity hash. For production, use your own Tailwind build step.
Does it work on a phone?
You can build on a phone using tap to add and move up or down. Drag and drop needs a mouse or trackpad.
What can I upload?
PNG, JPEG, WebP and GIF images up to 5 MB each. SVG is not accepted.
