What it does
Best for
I run a real e-commerce warehouse. I built these tools because I needed them myself — not as marketing gimmicks.
They cost nothing to give away. Every page runs entirely in your browser. No backend, no database, no tracking of what you scan or print.
If you eventually need a full warehouse management system, I built one of those too — but I'm not going to pressure you. Use the free tools as long as you want.
— Rudi, founder
When the free tools aren't enough — when you have 1,000+ SKUs, multiple stores, and a real warehouse team — Fulnex picks up where these end. Real-time inventory, picking workflows, multi-store sync, and 22 more modules on the way.
