Esoteric Database in Real HTML Tables
Esoteric Programming

Esoteric Database in Real HTML Tables

Esoteric Database in Real HTML Tables

A single PHP file that replaces WordPress's entire MySQL layer with a flat-file storage engine. Every database table becomes a folder of actual HTML files with styled <table> elements, a retro terminal UI, and prev/next pagination. It actually installs WordPress, runs plugins, ACF, and Elementor. For real. NOT FOR REAL USE!

Why are we doing this?

For the soul

It's not about money. It's about what we love to create. If an idea is exciting, we'll make it happen.

For experiments

We test new technologies on our own projects first, not yours. By the time you join, we'll already know the pitfalls.

For transparency

Here you can view the code, touch the interface, and see how we work. No NDAs or secrets.

Would you like us to do something for you?

We do these projects for ourselves. But our main job is helping clients. Check out our case studies or contact us to discuss your project.
