Formalini Forge: build desktop and web apps visually, with AI when you want it.
A Windows desktop tool for rapid application development: visual designer, code editor and AI conversation in one place. The editor, designer and build tools work without any AI key.
Project types
Visual designer
Drag, move, resize, copy and delete components, edit properties and colours, and undo from project history.
Code editor
Tabs, syntax highlighting, autocomplete, project-wide search and replace, and formatting for HTML, JSON, XML and XAML.
Plain-language apps
Describe what you want — a Hello World works with no code and no AI key; bigger requests use your own OpenAI or Gemini key.
Build and run inside
Build, run and read logs in the editor. Vue and React previews open in the built-in browser.
Data and hybrid code
Browse SQLite tables, bind them to grids in C#/WPF, and add a C DLL module with a generated bridge.
Git and extensions
Local Git and GitHub remotes, a command palette, dockable panels and ZIP extensions with snippets.
Requirements
Windows and the .NET 8 SDK, plus the compiler for the project you create: Visual Studio Build Tools, GCC or Clang for C/C++, Free Pascal for Pascal, Node.js and npm for web projects. AI keys are stored locally and protected by Windows.
An honest prototype
Forge is not yet a full replacement for Visual Studio or Delphi. Advanced features are strongest in C#/WPF, there are no breakpoints yet, and release installers are not digitally signed. React Native builds produce a source ZIP, not an APK or IPA. Review AI-generated code before publishing.
