CoAP Inspector

CoAP Inspector is a native SwiftUI app for sending CoAP requests and inspecting traffic on iOS, iPadOS, and your other devices. Use it to explore constrained devices, test servers, and iterate on CoAP resources without leaving the platform. Highlights • Build GET, POST, PUT, and DELETE requests with a clear editor tuned for real-world debugging. • Organise work with saved connections, bookmarks, and a local request history. • Work across iPhone, iPad, and Mac with a consistent, focused interface. • Synchronise connections and bookmarks between your devices (where available). Built for the CoAP world The roadmap includes observe (RFC 7641) streaming, coaps (DTLS) with pre-shared key and certificate auth, block-wise transfer (RFC 7959), and .well-known/core discovery (RFC 6690)—so the tool can grow with your projects.
