Wasp takes the declarative configuration approach that made Rails and Django productive and applies it to the modern JavaScript stack. A single main.wasp file describes the entire application structure — routes, pages, database entities, authentication methods, server operations, background jobs, and email sending — in a concise domain-specific language. The Wasp compiler reads this specification and generates a complete React frontend with TanStack Query for data fetching, a Node.js and Express backend, and Prisma-based database access with full TypeScript types that flow across the entire stack.
The batteries-included philosophy means features that typically require days of configuration work come built in. Authentication supports username-password, Google, GitHub, and other social providers in a few lines of configuration. Server operations with automatic client-side cache invalidation replace manual API endpoint creation. Typed RPC calls between client and server eliminate the serialization and type-safety gaps that plague separate frontend-backend setups. Background jobs, email sending, and deployment helpers are first-class framework features rather than third-party additions.
Wasp has attracted particular attention for its compatibility with AI coding agents. The declarative configuration file gives AI tools a clear specification of the entire application, reducing hallucination and structural errors that occur when agents must infer application architecture from scattered code files. Official plugins for Claude Code and Cursor provide AI agents with framework-aware context. With $5.2 million in funding led by HV Capital, 18,000+ GitHub stars, and YC backing, Wasp is actively developing toward its 1.0 release with Fortune 500 companies among its early adopters.
