Questions
Is it free?
Yes. Without an account, preview and download one file at a time with all its labels, with no daily limit and no watermark. Paid plans add batches of files, the API and support.
Is my ZPL stored?
On paid plans and with API keys, never: the label is rendered and returned. Without one, we may keep the ZPL of failed renders and a small sample of the others for up to 24 hours to find rendering bugs, then it is deleted. The editor remembers your last label only in this browser.
Does it match a Zebra printer?
It uses an engine written to emulate Zebra's ZPL II, so positions, fonts and barcodes come out as a printer draws them. Darkness and media can change a physical print; the compatibility page lists every command the engine draws.

OpenZPL accepts the same URLs, request bodies and headers as Labelary's v1 API, and answers with the same X-Total-Count header and error codes. Your client code stays as it is.
