◆ MeridianOS
Your personal website, as a retro desktop OS.
Windows you can drag. Folders you can open. A boot screen, a music player, hidden password-locked folders — even DOOM in the games folder. Built from plain static files you own forever: no backend, no database, no framework, no tracking.
▶ Try the live site demo — no signup, you're inside in seconds. · Read the manual
▶ Explore an example site made with MeridianOS on Neocities
▶ WATCH me build these demo files in less than 20 minutes - YouTube

What it is
MeridianOS is a free, open-source website builder that turns your personal site into an operating system. Visitors don't scroll a page — they explore a desktop: your art in the image viewer, your music in the tape deck, your writing in draggable windows.
- Everything is static files. Export and host anywhere — Neocities, S3, GitHub Pages, a Raspberry Pi in your closet.
- The admin app runs entirely in your browser. Edit content, drag your desktop layout, build icons — then export. Nothing ever leaves your machine.
- Two themes — Platinum and Vintage — switchable by your visitors.
- Fully offline. The exported site ships its own runtime and fonts in
vendor/— it runs with no internet at all.
