GolemUI – The new paradigm for JavaScript forms

We're a team of three friends who have been working with forms and Open Source for a decade, and we joined forces together to create something where we can apply all of our experience.

We recently released GolemUI, an Open Source library to generate forms dynamically from JSON definitions, with a typed layer to simplify authoring.

This library has a lot to offer. These are the main characteristics:

1. A JSON engine. The form is governed by a JSON definition that you can store in a DB, version, diff, or generate it with LLMs as a validated JSON.

2. We provide also 28 headless components (and growing) that you can style with CSS variables. We offer APIs so you can drop in Material, Shoelace, or your own components.

3. A DX typed authoring layer on top to write forms programmatically, that generates JSON. So you don't have to write it.

4. The same definition can render the UI components in React, Angular, Vue, Lit, or Vanilla JS.

5. We also have a deterministic MCP that has tools for to validate the model's output, generate JSONs or code, and ensure that the definition returned by the LLM is always valid.
