How a single HTML file replaces million-dollar SCADA software

After 20+ years in industrial automation — working with PLCs, RTUs, SCADA systems, and digital substations — I was frustrated. Every SCADA platform I used required:

Heavy installation (2-4 GB)

Dedicated server infrastructure

Annual license fees ($5,000-50,000/year)

Vendor lock-in

Windows-only deployment

So I built BitSCADA — a complete industrial SCADA system that runs entirely from a single HTML file . Open it in Chrome, Firefox, or Safari — and you have a fully functional SCADA with real-time visualization, function blocks, and industrial protocol support.

What makes it unique?

1. Literally one file

The entire SCADA — graphic editor, runtime engine, 53 function blocks, 65 graphic elements — lives inside a single HTML file (~240 KB online, ~3 MB offline with embedded React). No installation. No server. No database server (SQLite is built into the Gateway).

2. Full IEC 61850 support in a browser

This is the part I'm most proud of.…
