Key features

Zero Configuration

4567 requires no setup. Download, double-click, pick a folder — you're done.

Your folder structure becomes your website instantly. Folders become pages, subfolders become sections, and files just appear. "If you can organize files and folders, you can use 4567."

Interactive Folder Picker

Launch 4567 and use the built-in folder picker:

• Recent locations — Quick access to your last 5 projects
• Native file browser — Browse for any folder on your computer
• Current directory — Use the folder where 4567 is located

No command line required (though it's supported if you prefer).

Live Preview

As you edit files, add images, or reorganize folders, changes appear instantly in your browser. No manual refresh, no rebuild commands — just instant feedback as you work.

No Servers or Databases

The app runs entirely on your machine. No hosting infrastructure needed during development, no server configuration, no database setup. Works offline, stays private.

Static Export

When ready, export a complete static website:

• index.html and individual project pages
• Filter pages for categories, tags, years, clients
• SEO files — sitemap.xml and robots.txt
• All assets — images, videos, documents copied over
• Optimized HTML — clean, semantic markup

Host anywhere: Netlify, Vercel, GitHub Pages, any web server.

One-Time Purchase

A single $35 purchase covers unlimited projects. No subscriptions, no monthly fees, no vendor lock-in. You own the exported HTML/CSS and can modify it freely.

Advanced Metadata & Filtering

Organize projects with metadata that generates filter pages automatically:

• Year — /year/2024/
• Category — /category/web-design/
• Client — /client/company-name/
• Tags — /tags/responsive/
• Role — /role/lead-designer/
• Services — /services/ui-design/

Plain .txt File Fallback
