About OpenZPL
OpenZPL is an online ZPL viewer and a rendering API that turns Zebra ZPL II labels into PNG and PDF. It is made by The 01 Company, in Peru.
What the name means
Open as in open to use: no install, and an API that speaks the same protocol as Labelary so you aren't locked in. The hosted engine itself is not open source today.
How the engine is checked
The engine is written in Rust to emulate Zebra's ZPL II. We publish every command it draws or doesn't, the speed measured on the production server, and reader reports through the "Doesn't look right?" link under every preview. Marking a report fixed emails the person who sent it.
