Refine

Refine gives you a React framework that handles the CRUD, data tables, forms, and auth plumbing so you can focus on business logic for admin panels and internal tools. It's not a UI library. It's the layer between your UI components and your backend. MIT license. Works with any UI framework (Ant Design, Material UI, Chakra, or headless), any backend (REST, GraphQL, Supabase, Strapi, Appwrite, custom). The data provider abstraction means switching backends doesn't require rewriting your components.

The open source version is fully featured: routing, auth, access control, real-time updates, audit logging, i18n. Refine's paid tier (Enterprise) adds a visual app builder, dedicated support, and SSO. Pricing isn't public, contact sales.

Solo developers: free, and it'll save you days on every internal tool project. Small teams: free tier covers everything including RBAC. Growing teams: evaluate Enterprise if you want non-developers building internal tools with the visual builder. Large orgs: Enterprise for SSO and support.

The catch: Refine is React-only. If your team uses Vue or Svelte, this isn't for you. The abstraction layer is powerful but adds complexity; debugging issues means understanding both your UI framework AND Refine's data provider layer. And the 'works with any backend' promise means initial setup requires choosing and configuring a data provider, which can be confusing for newcomers.
