# SignalHub > SignalHub is a family of independent agentic services with human interfaces, designed to carry source context and human instructions forward. Canonical website: https://signal2hub.com/ ## What SignalHub does - Connects signals such as authorized mail, useful pages, notes, images and events with destinations allowed by the human's rules. - Preserves the distinction between receipt, delivery, agent activation, a human decision and reported completion. - Treats an attention notification as a request for a human decision, never as approval. - Keeps each service independently owned; this catalogue does not imply one shared runtime, store or release status. ## Service stages The 21 services are presented in four evidence-based product stages: established project, active project, in design, and on the roadmap. Project stage does not promise public access; each named project is the best place to confirm current access. SignalHub Webhook maps to the active PhxBiz/SignalWebHook project. ## Primary sources on this site - Landing page and service catalogue: https://signal2hub.com/ - Illustrated explainer and readable transcript: https://signal2hub.com/#film - Service relationship graph and catalogue: https://signal2hub.com/#services - Human-authority and service-stage answers: https://signal2hub.com/#questions
