Overview
UPCgen is a free, web-based barcode generator designed for e-commerce sellers, warehouse operators, and publishers. It creates valid UPC, EAN, ISBN, ITF-14, Code 128, FNSKU, and Data Matrix barcodes that pass GS1 validation and are accepted by platforms like Amazon, Shopify, and Walmart. With bulk generation and multiple export formats, it simplifies labeling workflows.
Terminal Mode by Even Realities is a feature for Even G2 smart glasses that turns the terminal into a live interface for coding agents. Developers can monitor agent status, approve actions, and give voice commands without returning to their laptop. It aims to keep users in flow and maximize token usage during AI-assisted coding sessions.
