Hi, I'm Praharsh 👋

I build free, open-source engineering software — tools that would otherwise cost thousands per seat, rebuilt for the browser and given away. More projects are on the way; here's the current flagship:

🏭 IPD Studio

A browser-based intelligent P&ID editor and HMI training simulator. Draw instrumentation diagrams with real ISA-5.1 symbols and validated tags, generate loop diagrams, datasheets, and instrument indexes — then run the same plant as a live operator screen with control loops, alarms, and process simulation. Local-first, no backend, AGPL, free forever.

IPD Studio — drawing a P&ID and running it as an HMI

▶ Try it live: pid-studio-praharsh.web.app

Buy me a coffee

Free tools run on coffee. If something I built saved you a license fee, a coffee keeps the pumps running — for this project and every one that comes after it.

What's next

  • Custom HMI widgets from your own SVG (animation bindings)
  • Deeper process simulation (thermal models)
  • DEXPI / CAD interoperability
  • …and new tools beyond IPD Studio — watch this space
