The original title is "Next.js Server Actions vs tRPC: how to actually choose"

Short summary

This article compares Next.js Server Actions and tRPC for handling typed data mutations in App Router applications. Server Actions are recommended for simple forms tied to a single web client, offering zero-client-JS form handling with React 19's useActionState and useOptimistic hooks. tRPC is preferred when you need request batching, query caching, or a shared API layer across web and mobile clients. The choice depends on app scaling needs rather than trends.

• •Server Actions suit simple forms on a single web client with React 19 hooks for state management
• •tRPC is better for request batching, query caching, and shared API layers across web and mobile
• •Both provide end-to-end type safety without hand-rolled REST endpoints
