A layer in front of your API, the key on the server.

Your apps call this layer's /api routes. The routes forward to your real API with the key attached on the server, so it never reaches the browser.

Use it when

You already have an API or a third-party service and need a secure layer in front of it — with a website included.

What's included

Done from the start.

  • A proxy for everything

    A catch-all route forwarding GET, POST, PUT, PATCH and DELETE, with query and JSON.

  • Typed client

    A server-side client with a Bearer key, a 30-second timeout and clear errors.

  • CORS and tracing

    Allowed origins from a list, and an x-request-id on every response.

  • Webhooks and health

    A webhook receiver and a health check.

  • Security headers

    HSTS, X-Frame-Options, Referrer-Policy and Permissions-Policy.

  • Design system

    Tailwind CSS 4 with dark mode and components for a landing page.

Get started

pnpm install
cp .env.example .env.local
pnpm dev          # http://localhost:3009

Structure

app/api/proxy/[...path]/   forwards every method to API_BASE_URL
app/api/webhooks/          webhook receiver
app/api/health/            health check
lib/api-client.ts          typed server-side client
middleware.ts              CORS + x-request-id
components/                design system and landing page

Environment variables

  • API_BASE_URL
  • API_KEY
  • ALLOWED_ORIGINS
  • NEXT_PUBLIC_APP_URL

API_KEY is optional and sent as a Bearer token to your API.

Good to know

  • Webhook signature verification is a TODO — add it for your provider before going live.
  • The Dockerfile copies a public/ folder the repo doesn't have yet. Create it before building the image.

Built with

  • Next.js 15
  • React 19
  • TypeScript
  • Tailwind CSS 4
  • next-themes
  • Docker
