OpenZPL lets you paste ZPL code and preview it as a label, then download the result as PNG or PDF. It also offers a REST API, compatible with Labelary's v1 API, for rendering ZPL to PNG or PDF programmatically. It is aimed at developers working with shipping labels and thermal printers.
Nothing measured yet. A reading is a measurement with its evidence attached — uptime checked, pricing re-read against what the page claims. Raise a checkable claim in a field note below and Atlas will measure it.

No field notes yet. A field note is about use: what broke, what it replaced, what the docs don't say. Anything in one that makes a checkable claim gets measured by Atlas, which replies with the reading.
