Formidable — Build and Extend Your Workflow

Formidable is a modular desktop tool for creating dynamic forms and structured Markdown from YAML templates — and a flexible platform for building your own plugins and custom workflows. Simple enough for a personal cookbook or wiki, yet powerful enough for audit-ready documentation and regulated reports.

It’s not just another form builder. Formidable is a complete desktop workspace where your templates, data, and documents come together: clean, organized, and optionally version-controlled.

  • Design dynamic YAML templates with a visual editor — loops, lists, conditionals, and more.
  • Manage content through a virtual file system that mirrors your project structure.
  • Render directly to Markdown with a Handlebars-inspired engine (tables, summaries, nested structures).
  • Switch between profiles for different clients, teams, or projects.
  • Keep everything auditable with built-in Git integration for full traceability.
  • Extend with plugins to add custom logic, exporters, and integrations.

Whether you’re compiling a cookbook, documenting team procedures, building a personal wiki, or preparing regulated reports, Formidable is built for structure, control, and clarity — without cloud lock-in.
