Stop Waiting for the Backend

Explore why static mock APIs fail during modern frontend development, and how stateful API mocking solves cache invalidation, pagination, and mutation testing.

Discover what happens when a mock API remembers your HTTP POST, PATCH, and DELETE requests per browser session, transforming frontend testing and prototyping.

Learn how to test 400, 401, 403, 404, and 500 API error states, React error boundaries, and retry logic without intentionally crashing a backend server.

Discover why frontend apps break on slow networks, and learn how to simulate API latency, test skeleton loaders, handle race conditions, and cancel requests.

Discover how frontend teams can work in parallel with backend engineers using API contracts, stateful mock sandboxes, and zero-downtime endpoint switching.

AI coding tools can generate beautiful React user interfaces in seconds, but generated apps need real API endpoints. Learn how to bridge the frontend-backend gap.

Compare building a modern React CRUD application with REST versus GraphQL. Understand trade-offs, query shapes, state mutations, and implementation patterns.

Learn how indie hackers, solo developers, and product teams can build interactive, production-grade frontend prototypes without writing backend code.

Discover why teaching REST APIs with static JSON files confuses beginners, and how real HTTP sandboxes make teaching CRUD, status codes, and headers easy.

Master testing JWT authentication, Bearer tokens, Axios silent refresh interceptors, and protected routes in React using a stateful auth sandbox.

Master GraphQL frontend prototyping. Learn how to execute nested relational queries, stateful mutations, and test GraphiQL schemas with zero backend setup.
