Formeo
Build Dynamic Forms Without the Framework Lock-In
Build Dynamic Forms Without the Framework Lock-In
Overview
Formeo is a zero-dependency drag and drop form builder that gives developers a visual editing experience without tying them to any specific framework. Build complex, responsive forms with an intuitive interface, then render them anywhere on the web.
Most form builders are either bloated framework-specific packages or limited in what they can do. Formeo takes a different approach: it is a lightweight, self-contained library that works with any stack. Drop it into a vanilla JavaScript project, wrap it in React or Angular components, or load it from a CDN. The result is the same. A powerful form editor that your users will actually enjoy.
The library ships two main components. The FormeoEditor provides a full visual form-building interface with drag and drop support. The FormeoRenderer takes the saved form definition and turns it into a functional, validated HTML form. This separation means you can build forms in one context and render them in another.
Who It’s For
- Formeo is built for teams that need form-building capabilities without the overhead of a full CMS or page builder.
- SaaS Platforms — Give your users the ability to create custom intake forms, surveys, or application workflows
- Internal Tools — Build admin panels and data entry interfaces that non-technical staff can modify
- Customer Portals — Let clients design their own forms for submissions, feedback, or orders
- Developer Tools — Embed form creation into your own application without maintaining a custom builder
- Agency Projects — Ship form-heavy client projects faster with a reusable, configurable component
Why Formeo
Formeo eliminates the trade-off between flexibility and simplicity. You get a production-ready form builder that handles complex layouts, conditional logic, and custom field types, all while keeping your bundle size small and your dependency tree clean. It works with whatever stack you already use, and it does not force you into a particular framework or architecture.
