DocuPilot — AI-powered auto documentation for GitHub repos (built with Next.js 16)

[AkrMcmr]

I built DocuPilot — a GitHub App that automatically generates and updates your README, CHANGELOG, and API docs every time you push code.

How it works

1. Install the PushDocs GitHub App
2. Push code as usual
3. Get a PR with updated documentation — review, edit, merge

No config files. No CLI. Just install and push.

Tech Stack (all Next.js 16)

• Framework: Next.js 16 App Router on Vercel
• AI: Claude API (Anthropic) for code analysis & doc generation
• Auth: GitHub OAuth via Next.js route handlers
• Payments: Stripe integration
• State: Vercel KV (Redis)
• Background processing: Next.js after() API for webhook handling

What I learned building with Next.js 16

• The after() API is a game-changer for webhook processing — no need for external queue services
• App Router + Server Actions made the GitHub OAuth flow much cleaner than Pages Router
• ImageResponse for dynamic OG images works great for social sharing
• Server Components eliminated most client-side state management

Live Demo

Here's a real PR generated by DocuPilot: docupilot-test#3 (+147 lines of auto-generated docs)

Pricing

The application offers a free tier for 1 repo, forever free, no credit card required. Otherwise it is a paid app.

Would love feedback from the Next.js community! What doc types would you want auto-generated?

Leveraging Next.js 16 features like after() for webhook handling, Server Components, and App Router shows a deep understanding of modern frameworks and clean architecture.The zero-config approach and clear GitHub OAuth integration make adoption seamless, while the live PR demo demonstrates practical value in maintaining accurate, up-to-date documentation.
