Fillament
A modern Formik alternative with AI auto-fill support
Fillament is a type-safe form library for complex React apps. It helps teams build multi-step, conditional, production-grade forms with granular re-renders, free DevTools, privacy-safe analytics, and built-in AI agent auto-fill support — so forms work better for both users and automation.
We built Fillament for React teams that have outgrown simple form state.
Formik has been a default choice for years, but complex product flows often need more than “collect values and validate on submit.” Real-world forms have conditional sections, multi-step flows, dependent fields, performance constraints, analytics needs, AI-assisted workflows, and teams of developers who need confidence when refactoring.
Fillament is our take on a modern Formik alternative:
✅ Type-safe fields
✅ Granular re-renders
✅ Conditional flows
✅ Built-in AI agent auto-fill support
✅ Free DevTools
✅ Privacy-safe analytics
✅ Built for large React teams
