Nothify // Autonomous 404 page generation for Next.js

Showcase
,
1

Nothify is an AI-powered agent that analyzes a Next.js repository and generates a framework-correct 404 page, either as downloadable code or as a clean, review-ready GitHub pull request.

What Nothify does:

  • Analyzes a Next.js repository (App Router or Pages Router)
  • Detects language and styling setup (TypeScript/JavaScript, Tailwind, MUI, CSS Modules, etc.)
  • Generates a stack-correct 404 page from a selected template
  • Lets you download the code or automatically opens a GitHub pull request

Design principles:

  • Zero manual configuration
  • Safe by default (detects existing 404 files before overwriting)
  • Focused on taste, clarity, and developer experience rather than heavy automation

Current capabilities:

  • 5 handcrafted templates with light and dark themes
  • Works with public and private repositories
  • GitHub OAuth for automated PR creation
  • Code export without requiring GitHub access

Built with:

  • Appwrite Auth for secure GitHub OAuth
  • shadcn/ui and Tailwind CSS for UI
  • Groq for AI code generation
  • Vercel AI SDK for orchestration

Hey everyone! :wave:

Thanks for the initial feedback! I’ve made some significant improvements to Nothify based on your testing.

What’s fixed:

  • The loading/dialog issue is now resolved
  • Added automatic repository forking for repos you don’t own
  • Improved state persistence through the GitHub OAuth flow

New flow for repositories you don’t own:

  1. Paste any public Next.js repo URL (even if you don’t own it)
  2. Select a template and theme
  3. Nothify analyzes the repo structure
  4. Connect your GitHub account (if not already connected)
  5. Nothify automatically forks the repo to your account
  6. Creates a clean, review-ready pull request from your fork

Example with the repo you tested:

I just tested with github.com/refetch-io/refetch and it worked perfectly:

The PR includes a framework-correct 404 page that matches the repo’s stack (TypeScript, Tailwind, App Router).

Key improvements:

  • Your progress is now preserved through OAuth (no more starting over)
  • Clear UI feedback when forking is needed
  • Handles both repos you own and repos you don’t own seamlessly

Thanks again for helping me catch these issues! :pray:

Thanks a lot! Appreciate that :raising_hands:

I’ve been iterating based on feedback from a few communities and focusing on smoothing the flow and edge cases.

If you or anyone on your team has a chance to try it, I’d genuinely value feedback on usability, DX, or anything that could make it more useful in real projects.

Shared a short X thread with the latest flow breakdown and screenshots.

Happy to hear feedback.

Quick update since sharing this:

  • Added dark mode (via next-themes)
  • Recorded a full end-to-end demo using a public repo
  • Shows auto-detection → fork (if needed) → clean PR creation

Demo repo: github.com/umami-software/website

Update shipped based on feedback :rocket:

A few people asked if they could preview the page before opening a PR…totally fair.

I’ve added a live preview so you can test and only then create a PR.

Would love more suggestions on what to add next.

Quick iteration on Nothify.

Tried a more expressive illustrated 404 using a vintage background + overlay, keeping it simple and production-safe.

I wrote a short blog sharing the thinking and architecture behind Nothify… repo analysis, preview-first flow, and PR automation.

Posting it here in case it’s useful:
