Inbound ZPL label data from various origins
Focus your IT on what matters most.
Every production line runs on labels. Every label starts as data, a PDF, a shipping manifest, an order. But somewhere between that data and the thermal printer, the process breaks. And every fix becomes an IT project lasting days or weeks.
Sign up in 30 seconds. No credit card required.
One click in the dashboard. Your key is ready.
Send a PDF, get ZPL. Or the other way around. Under 200ms.
REST API or native CLI. 3 lines or 1 command. That's it.
DocumentationI have PDFs from carriers but the printer wants ZPL. Or vice versa. I have to manage two systems.
Bidirectional PDF ↔ ZPL conversion in a single API.
One integration. Zero separate systems.
The line stops if I get a label wrong. Or if volumes exceed forecast.
Dynamic over-budget keeps printing even when volumes spike. Every operation is verified, no label is ever lost or double-charged.
The line never stops. Even during peaks.
On-premise software costs thousands of euros per year. And I have to maintain the servers.
Cloud-native, stateless, pay-per-use. No installation, no fixed licenses.
Pay only for what you use. Predictable costs. From €0 the first month.
Every warehouse runs on labels. Every label starts as data, a PDF, a shipping manifest, an order. But somewhere between that data and the thermal printer, the process breaks.
We built zplflow because the world doesn't need another label editor. It needs label infrastructure, an API that turns PDFs into ZPL, ZPL into PDFs, and both into pipelines that transform, validate, and optimize every label that touches a box.
Cloud-native. Stateless. AI-ready. Five minutes to first label. That's zplflow.
We didn't start from a pitch deck. We started from years of customer requests, the same label modifications asked over and over, by different teams, in different warehouses. 20 years building software, 10 of them in logistics IT, taught us the problem was never the printer or the label. It was the lack of infrastructure. zplflow is bootstrapped, we built it to solve the problem, not to raise money for it.
