+## tRPC
+
+[tRPC](https://trpc.io/) has a lot of goal and design similarities with Express Zod API: you can describe your
+type-safe API using zod and access it from a frontend client. The main difference between the two frameworks is that
+Express Zod API keeps compatiblity with REST and provides out-of-the box OpenAPI schema generation.
