Gumnut is a lightweight real-time collaboration platform that turns existing apps (notably HTML forms) into live, multi-user workspaces with co-editing, presence indicators, and an audit trail. It provides concurrent editing with live cursors, character-level attribution, and a global WebSocket session per document. Version history and an audit log preserve durable snapshots with commit and revert capabilities; edits can be hosted in an edit-session primitive until users commit, enabling forms to reach a complete state before finalization. AI agents can be dropped in with contextual understanding of forms and documents, and collaborative documents and diagrams are supported with rich text and interactive, Figma-like diagrams. No required database schema changes make integration easier across old and new codebases. It offers multi-stack support for React, Vue, Angular, and vanilla JS, with first-class React components. Developer docs include a Docs hub, a React components guide, token generation, a useGumnutDoc hook, actions such as load, commit, revertAll, and status/troubleshooting utilities, plus an agent API. Authentication uses signed JWTs; sessions transport over WebSockets; storage comprises in-session state plus long-term snapshots; hosting options include hosted by Gumnut, enterprise deployments, or self-hosted solutions. Pricing is hybrid: free tier plus subscription and usage-based elements; exact pricing is available by inquiry.
