Hi Product Hunt!
I built PfdLabs because every time I needed to draw a mineral processing flowsheet, I had to use generic tools like Visio or draw.io — with no industrial symbols, no crushers, no thickeners, no flotation cells. I spent more time fighting the software than designing the actual process.
So I built PfdLabs specifically for process engineers and metallurgists. It has 100+ symbols across 3 styles — photorealistic 3D, detailed 2D technical illustrations and simplified schematic symbols inspired by HYSYS and Metsim. Everything drag-and-drop, runs in the browser, no installation needed.
Free plan includes 5 diagrams and full symbol library. Pro is €3/month for unlimited diagrams, PDF export and cloud sync.
Would love feedback from the community — especially from anyone working in mining, metallurgy or process engineering!
