Topicbraid: MQTT Design

Topicbraid is a local MQTT governance desk for IoT developers, controls engineers, homelab operators, consultants, and platform teams who need to reason about topic shape and authorization without connecting to a broker. See how topic depth, subscriber fanout, wildcard breadth, and ACL evidence combine before a namespace becomes permanent. KEY FEATURES - Topic-filter and wildcard register - MQTT + and # matching helper - Subscriber fanout view - ACL coverage and owner screen - Retained-message lifecycle notes - Tenant and device namespace planning - Topic governance artifact - Zero broker credentials required - Native structured-file or CSV import - Local PDF, workspace JSON, and domain-artifact export - 48 original offline technical reference plates - No account, ads, analytics, tracking, IAP, or subscription Topicbraid models entered topic filters and policy assumptions; it does not connect to, publish to, subscribe to, or configure an MQTT broker. Confirm broker-specific ACL syntax, identities, shared subscriptions, retained state, QoS, persistence, and production behavior with controlled tests.
