Project-OneFile

A collection of single-file HTML programs.

Each program is exactly ONE .html file that runs independently by opening it in a browser. There are no build steps, no installers, and no shared code between programs.

---

How to Run

1. Open this repository
2. Navigate to any folder under apps/
3. Download a .html file
4. Open it in your browser (double-click)

Works offline by default, unless a program explicitly uses online assets.

---

Core Rule

ONE program = ONE file

• Each .html file is a complete program
• HTML only
• CSS must be inside <style>
• JavaScript must be inside <script>
• Programs must run by simply opening the file

---

Folder Structure

apps/ ├─ game/ # board games, chess variants, gomoku, etc. ├─ minecraft/ # minecraft-inspired experiments ├─ simulation/ # physics, math, fluid, and visual simulations ├─ program/ # small interactive programs ├─ tools/ # utilities, viewers, trainers

Folders are only for organization.
Each file inside them is still an independent program.

Programs

Each program below is a single, independent HTML file. Open the file in a browser to run it.

Bugs & Issues

Some programs are experiments and may contain bugs.

If you find an issue, please open a GitHub Issue and include:

• file name
• what you expected vs what happened
• browser + OS
• screenshot if possible

Improvements Wanted

Possible future improvements:

• Better mobile support (some programs already support mobile)
• Clear instructions at the top of each file
• UI and performance refinements
• Code cleanup

---

Browser Support

• Tested mainly on Chrome
• Other modern browsers should work, but are not guaranteed
