Alpha

Describe your website. The assistant builds it — on your machine.

ForgeDesigner is a small desktop app with an AI assistant. It creates the pages, writes the Markdown and shows you a live preview. The result is plain files in a folder on your disk — no page builder, no lock-in, no cloud unless you want one.

Download the alpha How to install ForgeCMS

Free app, open source, no subscription. macOS (Apple Silicon) and Linux (x86_64).

What works in this alpha

AI assistant with tools

The assistant lists, reads and writes files and runs commands inside your workspace folder. You watch it work, and the file tree updates as files appear.

ForgeCMS output

The first plugin builds ForgeCMS sites: pages in SML plus Markdown, ready to be pushed to a Git repo and served.

Live preview

Select a page or a Markdown file and see the layout next to the editor. Changes by you or the assistant show up right away.

Offline by default

Out of the box the assistant answers from a built-in mock: free, and nothing leaves your machine. A real model is one config line away.

Bring your own key

Connect any model on OpenRouter with your own key — free models included. You pay the provider directly, with no markup from us.

Your files, your repo

Everything is plain text in a folder you own. Edit a sentence by hand, then ask for the next step.

The app is free. Plugins are a one-time purchase.

Buy a plugin once and keep it. Minor updates included. No subscription.

Built with its own tools

ForgeDesigner runs on Forge4D, an open app platform. Its whole UI — docks, file tree, editor, assistant — is itself written in SML (layout) and SMS (logic), the same simple languages it uses for your pages.

DockingContainer {
    id: rightDock
    dockSide: right

    VBoxContainer {
        id: preview
        rightDock.title: "Preview"
    }
}

An AI on your machine needs guard rails

Permissions you confirm

The app declares what it needs — workspace files, running programs, network access to openrouter.ai — and asks you once on first start.

No shell strings

A few commands (git, ls, cat, ssh, scp) run directly. Anything else opens a dialog where you decide, once or for good.

Keys stay in the runner

Your API key lives in a private file and is never handed to the app or the model.

Prompt injection is still a real risk: the trusted commands can reach whatever your user account can. That is a big part of why this is an alpha.

Try it

Unzip the download. The alpha is only ad-hoc signed, so remove the quarantine flag once:

Linux (x86_64)

Unpack and start:

tar xzf ForgeDesigner-2026.9.23-linux-x86_64.tar.gz
