Hey Product Hunt community! 👋
I'm the maker behind Zonelyn.
As software engineers and architects, we spent countless hours in architecture reviews and RFC discussions fighting with diagramming tools. We either found ourselves wrestling with clunky menus in legacy enterprise software, or spending 30 minutes manually aligning boxes on freehand whiteboards just to make a diagram presentable for docs.
We built Zonelyn to be the visual workspace we always wanted:
1. Snappy & Tactile: A 60fps canvas with magnetic snap ports, color-coded zone containers (for VPCs, subnets, and clusters), and clean connectors that follow your blocks naturally.
2. Dual Aesthetics: Sketch casually during an ideation call, then toggle to clean technical vector mode for your official RFCs in a single click.
3. No Fluff: A focused tool built for real engineering workflows — complete with live flow simulation, production architecture blueprints, and high-res SVG/PNG export.
Zonelyn is completely free to try at [zonelyn.com](https://zonelyn.com).
I’d love to hear your thoughts and feedback:
- What's your biggest friction point when documenting system designs today?
- What cloud templates or shape libraries would you find most useful?
Thanks for checking out Zonelyn! 🚀
