Well-designed backend types plus a Nestia-generated SDK give AI enough context, constraints, and simulation hooks to build frontend code reliably.

Nestia’s upgraded Swagger generator produces cleaner OpenAPI documents directly from rich TypeScript and NestJS metadata.

Nestia Editor combines Swagger UI, generated SDKs, and a cloud TypeScript playground for testing OpenAPI APIs with real typed code.

For frontend teams, a generated SDK and simulator can replace brittle Swagger UI and MSW workflows with type-safe API integration.
![[Nestia] I made backend simulator for frontend developers (similar with MSW, but fully automated)](https://media2.dev.to/dynamic/image/width=1000,height=500,fit=cover,gravity=auto,format=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2F07td2fzq78nkzyg5m132.png)
Nestia generates a backend simulator for frontend developers, so typed API flows can be built and tested before the real server is ready.
![[Nestia] Make NestJS 30x faster with fastify](https://media2.dev.to/dynamic/image/width=1000,height=500,fit=cover,gravity=auto,format=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Fbk0bupsf8937pu1vmz6o.png)
Using Nestia with Fastify can push NestJS throughput dramatically higher by combining faster validation and serialization with a faster HTTP server.

Nestia can generate end-to-end test functions from your NestJS controllers, turning API types into reusable, type-safe test scaffolding.

Nestia replaces decorator-heavy NestJS boilerplate with pure TypeScript types, fast validation, fast serialization, and generated SDKs.
