ForgeDesigner Alpha: an AI assistant that builds websites on your own machine

A developer has released the first alpha of ForgeDesigner, a desktop app for macOS (Apple Silicon) and Linux (x86_64) that lets users describe a website in plain language and have an AI assistant generate the pages, Markdown and live preview as plain files on their own disk. The app runs on the open Forge 4D platform, whose UI is written in the SML/SMS languages atop a native C++ runner on Godot 4.6, and gives the assistant file and command tools inside a workspace folder with guard rails including per-command approval dialogs and API keys stored in a chmod 600 file. The developer notes prompt injection remains a real risk and is a major reason the release is labeled alpha.

Today I'm releasing the first alpha of ForgeDesigner for macOS Apple Silicon and Linux x86 64 . ForgeDesigner is a small desktop app where you describe a website in plain words and an AI assistant builds it: it creates the pages, writes the Markdown, and shows you a live preview. The result is plain files in a folder on your disk. You don't need a hosting account, you don't get locked into a page builder, and nothing lives in somebody else's cloud unless you put it there. 👉 Download: https://codeberg.org/CrowdWare/Forge4D/releases/tag/v2026.9.23-forgedesigner-linux https://codeberg.org/CrowdWare/Forge4D/releases/tag/v2026.9.23-forgedesigner-linux I wanted something between "hand-write HTML" and "rent a website builder". The things people use today, WordPress, website builders and IDEs, all ask you to learn their world first. I wanted a single place where I can say "make me a landing page with a short intro and a contact section" , then look at the files, change a sentence by hand, and ask for the next step. ForgeDesigner is built on Forge 4D https://codeberg.org/CrowdWare/Forge4D , an open platform where apps are written in two small languages: The whole designer UI, including the docks, the file tree, the editor and the assistant tab, is itself an SML/SMS app running on the native Forge runner C++ on top of Godot 4.6 . A few lines from its layout: DockingContainer { id: rightDock dockSide: right VBoxContainer { id: preview rightDock.title: @Strings.tabPreview } } list files , read file , write file and run command inside your workspace folder ~/ForgeWorkspace/... . You watch it work in the transcript, and the file tree updates as files appear. An AI that can write files and run commands on your machine needs guard rails. ForgeDesigner has these: openrouter.ai , and the runner asks you once on first start. git , ls , cat , ssh , scp runs directly. Everything else opens a dialog where you decide, once or for good. chmod 600 file in the runner's data folder 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 can. That's a big part of why this is an alpha. macOS Apple Silicon : unzip, then remove the quarantine flag once. The alpha is only ad-hoc signed. xattr -dr com.apple.quarantine ForgeDesigner.app Linux x86 64 : tar xzf ForgeDesigner-2026.9.23-linux-x86 64.tar.gz ./ForgeDesigner/ForgeDesigner.x86 64 :free need no credit. ~/Library/Application Support/Godot/app userdata/ForgeDesigner/ ~/.local/share/godot/app userdata/ForgeDesigner/ forge ai keys.sml and run chmod 600 forge ai keys.sml : Keys { openrouter: "sk-or-v1-..." } forge ai.sml , switch the provider: Ai { provider: "openrouter" chatModels: "qwen/qwen3.8-27b:free, nvidia/nemotron-3-super-120b-a12b:free" } The first model is used, and the others are fallbacks.
