A website tool that uses the real power of your computer.
Traditional content management systems live in the browser and lock your data in proprietary databases. Splitleaf doesn't.
Meet your new local workspace.
Design visually.
With AI.
Click, edit, move and style elements on the canvas. Splitleaf writes clean class-based HTML and CSS directly to your project.
When AI has created a design, use the state panel to quickly see the CSS changes in a list.
Valid structures, visual undo and real files keep experimentation reversible.

Full control of
what goes live.
We grew tired of the flawed "Publish" button that releases every change you've made.
From review to live, in one view. Splitleaf turns the full release process into a visual board your entire team can understand and manage.
Give employees and contributors access to make changes, review or publish work to the live site.
Selective publish
Select individual pages, content, design changes or files and publish only them.
Share the workload
Review, stage or publish coworkers' changes, and see progress.
Git-backed
Changes made in Splitleaf are stored and tracked in GitHub, without your team having to think about it.
Bring your existing site.
Point Splitleaf at a folder with real HTML and CSS and it becomes an editable project, structure, classes and content intact.
-
Real files in, real files out
-
Git history preserved, nothing rewritten
- No proprietary format to get locked into

This site is a folder.
We built it with Splitleaf.
splitleaf.eu is a Splitleaf project. Pages, components, styles and Markdown content sit in one folder, and every publish is a Git commit.

The questions we would ask
Why not just use Claude Code?
You can, inside Splitleaf. Claude Code runs in the agent panel on the Claude plan you already have. It works on the same files as the visual canvas, the CMS and the publish board. People who do not code can review, edit and publish. Every change is staged for you to keep or undo.
Is the AI local today?
Not yet. The agent calls the provider you connect: Anthropic, OpenAI or OpenRouter, on your own key. Everything else is already local. The app, your files, your edits and the design work all run on your Mac or Windows PC. No server of ours sits between you and the model. Local models are the next step, and the architecture is built for them.
Is this a static site generator with a visual editor?
The output is static HTML and CSS, so that part is true. The difference is who can use it. There is no build configuration, no template language and no terminal. A designer or a marketer designs, edits content and publishes from one app.
Do I pay Splitleaf for AI?
No. You connect your own key and pay your provider at its normal price. Splitleaf runs no server between you and the model and adds no markup. The agent panel shows the usage of each chat.
Where are my API keys stored?
On Splitleaf's server in the EU, encrypted, for that one site. A key is never written to your site folder, so it never ends up in your repository.
What happens after the 12 months of updates?
The app you bought keeps working and keeps publishing. The licence includes 12 months of updates. A future major version is an optional paid upgrade.
Does it run on Mac and Windows?
Yes. Splitleaf is a native desktop app for Mac and Windows. It runs on Intel and Apple silicon Macs with macOS 11 or later, and on Intel, AMD and Arm PCs.
