About

Solving real WordPress
problems, not imaginary ones

ByteCore Stack was born out of frustration with plugins that do too much, load too slowly, and hide features behind paywalls. Every tool we ship solves a single, well-defined problem — and does it properly.

Built with modern PHP, zero jQuery dependency, and a relentless focus on performance. Each plugin follows WordPress coding standards, has full accessibility support, and is designed to stay out of your way.

  • Lightweight — no unnecessary database queries
  • Open source — fork it, audit it, own it
  • Maintained — bugs fixed, compatibility kept current
  • No telemetry — your data never leaves your server

Each plugin is standalone — install only what you need.

From install to running
in under 5 minutes

Every ByteCore Stack plugin follows the same zero-friction setup.

Install from WordPress.org

Search the plugin directory, one-click install, activate. No zip files, no FTP required.

Configure in Admin

Fill in a single settings page inside your WordPress admin. No config files, no code changes needed.

Done — it just works

No ongoing maintenance, no licence keys, no cloud dashboards. The plugin runs quietly in the background.

Open Source

Audit the code. Fork it. Improve it.
