About the network
Each site in the Vertex Network is operated independently. There is no shared login, no cross-site tracking, and no upsell flow between them — the only thing they share is a maker who keeps the scope tight: one problem per tool, no SaaS bundle, no signup wall. Each tool stands or falls on its own merit.
More tools are added when a specific operational problem comes up often enough to warrant a focused utility. If you have a small-but-real workflow problem you'd like a tool for, the contact address on the Contact page is open.
