Forms as Portable Data
Forms are everywhere, and yet we keep rebuilding them. A form built for React can’t be reused in Angular. A form locked inside component code can’t be stored, versioned, or A/B tested, or handed to a non-engineer to edit. And a form that only exists as JavaScript is awkward for a machine to generate, because there’s no clean shape to target.
GolemUI solves that with a simple concept: forms are data, not code.
With GolemUI you can generate forms in a serializable JSON Schema, making your forms portable, storable, and framework-independent. On top of that we offer a TS API, a strictly typed builder that constructs the schema for you. The portability of data, with the ergonomics of typed code. Best of both worlds.
And for free you get form states, conditional fields, validations, accessibility WCAG 2.1, i18n, a complete UI kit, and an MCP server to validate the JSON API and the TS API so your agent can't hallucinate the generated definitions.
Oh, and it's Open Source and free.

About Raúl Jiménez
I'm a software engineer who loves JS frameworks, web tech, and building for the web. I'm co-founder of GolemUI, a declarative form engine that lets you define forms as serializable schemas instead of coding the UI for every framework.
I'm a Google Developer Expert in Angular, I mentored at the Women Developer Academy, and I'm an Open Source contributor and speaker. After 20+ years doing this, I guess I've learnt a few things worth sharing.
Outside of work you'll find me playing chess, behind a drum kit, or watching FC Barcelona. I'm also into comics, board games, and pretty much anything geeky.
