Key features

Zero Configuration:

4567 requires no setup. It just works.

Simply download and run it, then pick any folder on your computer. Folders instantly become pages, and files (images, text, Markdown, video, audio, etc.) just appear on the site.

In other words: “If you can organize files and folders, you can use 4567”.

No Servers or Databases:

The app runs locally on your machine (offline and private).

There’s no need for hosting infrastructure during development – you only upload the final static export. This makes it inherently secure and reliable (no server breakage or downtime).

One-Time Cost & Unlimited Sites:

A single purchase covers unlimited projects.

Unlike other website builders (which have monthly fees or hosting costs), 4567 is a one-time $35 investment with no subscription. After exporting, you own the plain HTML/CSS (no vendor lock‑in).

Instant Live Preview:

As you edit files or add images in your folder, the site updates in real time. This rapid feedback loop (no need to rebuild or refresh) enables you to see immediate results so you can iterate quickly and focus on your content.

Export-Ready Static Output:

When ready, run the “Export website” command.

4567 will build a complete static site (including an index.html, pages for each project, category/tag pages, sitemap/robots for SEO, etc.).

The exported site is optimized for performance (fast load, responsive design) and can be hosted on any hosting platform. You are also free to modify the HTML/CSS as needed.

Advanced Customization (No Code Required):

Though it’s no-code, 4567 offers features like custom per-project colors, featured projects, tags/categories, and even the ability to include custom HTML in a folder if needed.

However, all adjustments are made via simple file edits, not coding in a CMS.
