Labelary alternative
OpenZPL is a Labelary alternative that accepts the same v1 requests, so moving is a matter of changing the hostname and adding a key. Paid plans start at $29 a month.
Your file is downloading.
Free, with no daily limit. A free account also saves your designs and gives you an API key.
curl https://api.openzpl.com/v1/printers/8dpmm/labels/4x6/ \ -H "X-API-Key: oz_live_…" -H "Accept: application/pdf" \ --data-binary @label.zpl > label.pdf
When it is worth switching
If Labelary's free tier does what you need, stay: it has 5,000 requests a day, and OpenZPL's free tier is smaller on purpose. OpenZPL is worth it when you are about to pay: a lower entry price, EPL and TSPL input as well as ZPL, and a live designer and Excel-to-label tools on the same account.
How it compares
The full comparison has the tables and the differences we measured on 2026-10-20. Two engines can differ in fonts and barcode details, so try your own labels first: the compatibility page lists every command.
Other options
LabelZoom converts between many label languages and BarTender files. If you need the engine inside your own network, a Custom plan runs on your servers.
Questions
Is it free?
Yes: preview and download one file at a time with all its labels, without an account, with no daily limit and no watermark. Paid plans add batches of files, the API and support.
Do I have to change my code?
Only the hostname and an X-API-Key header. The [migration guide](/migrate/labelary/) has the steps.
Is the output pixel-identical?
No two engines are. We publish what differs on the [comparison page](/vs/labelary/).
