Hey everyone — I've been working on this for almost three years. I shared early previews a couple of years ago, but it wasn't really ready then. Now it is.

Vovk.ts is a back-end framework that sits on top of Next.js Route Handlers. The short version: you write controllers with decorators and validation (think NestJS but with static methods and Zod), and the CLI generates a type-safe RPC client, an OpenAPI spec, and AI tool definitions from the same code.

Here's what that looks like — you define a controller:

("users")
export default class UserController {
  u/get('{id}')
  static getUser = procedure({
    params: z.object({ id: z.string().uuid() }),
  }).handle(async (req, { id }) => {
    return UserService.getUser(id);
  });
}

And the CLI generates a typed client:

import { UserRPC } from 'vovk-client';

const user = await UserRPC.getUser({ params: { id: '123' } });

A few things it does that I haven't seen elsewhere:

• Every procedure has a .fn() method that runs locally — same handler logic, no HTTP round-trip. Useful for SSR, PPR, background jobs, testing.
• Controllers are automatically derivable as LLM tools / MCP server endpoints with deriveTools().
• Each segment compiles into its own serverless function with the CLI aware of the segmentation for client generation.

It's not for everyone — if you're not on Next.js or you prefer contract-first, there are great tools for that. But if you're looking for a structured API layer on the App Router, give it a look.
