Echo + a typed contract
An addition to Echo, not a replacement.
EchoNext is useful when your HTTP boundary benefits from explicit request and response types. Standard Echo remains available for routes that need full manual control.

When EchoNext fits
Choose typed routes for public contracts
Request validation, stable response types, and generated API documentation are most valuable on endpoints consumed by other teams, SDKs, or third parties.
Keep standard Echo where flexibility wins
Use normal Echo handlers for unusual streaming responses, highly dynamic payloads, or endpoints where a generated schema would not improve the interface.
Mix both in one service
EchoNext wraps Echo rather than hiding it. Middleware, route groups, context methods, static serving, and ordinary handlers can live beside typed routes.
Understand the core conceptsAdopt it one route at a time.
You do not need to rewrite an Echo application to start using typed endpoints.
