ZPLab is a free, open-source visual label designer and ZPL editor for ZPL-compatible printers. Users can place text, barcodes, shapes and images on a canvas while the generated ZPL updates in real time. When imported ZPL is left untouched, commands, whitespace and comments can be preserved byte-for-byte on export. The designer supports 28 barcode symbologies, including linear, 2D, postal and GS1 variants. Batch labels can draw variables from CSV columns; desktop versions also support Excel worksheets and read-only SQLite, PostgreSQL and MySQL databases. Preview and printing options depend on platform and include Labelary, printer firmware, network printing, Zebra Browser Print, the desktop spooler and USB. Desktop editions include a local MCP server through which an AI assistant can read and edit the open label. The app requires no account, is MIT licensed and offers 32 interface languages. Its self-hosted web build serves static files, with preview and printing in the browser; server-side features are planned but unscheduled. The README states that browser support models 125 of 225 ZPL II commands, with desktop covering two more through a connected printer.
Who it is for
ZPLab suits people designing and printing labels for ZPL-compatible printers, including users who do not know ZPL. Desktop users who need database inputs or the local AI-assistant connection may value its additional options.
