Tester vs MQTT Connect

The first mobile app to handle any developer task on the go. Main features: - REST, GraphQL, WebSocket, SOAP, JSON RPC, XML, HTTP, HTTPS, etc. - All types of HTTP requests: GET, POST, PUT, PATCH, DELETE, HEAD, OPTIONS, COPY, LINK, UNLINK, PURGE, LOCK, UNLOCK, PROPFIND, VIEW. - Powerful GraphQL editor with full-scale experience: body editor with Queries, Mutations, Subscriptions and syntax support; variables editor; documentation explorer; request settings and metadata. - WebSocket testing tool. Handles connection and message exchange via WS or WSS. - API calls with any kind of request data encoding and transfer type (query params, URLEncoded params, FormData, raw data, send files from device storage, cloud, remote server). - Settings. TLS can be skipped, redirects can be disabled, timeouts are adjustable. Weak SSL verification can be enabled and replaced with self-signed certificate. - Import request or collection by curl, link or file from your device. And naturally, there is any type of collection for you: Swagger, OpenAPI, Postman, YAML. - Need to share request in seconds? Deep link and cURL command supported. - Apple Watch app. Allows to send API requests directly from your wrist. - Integrations: Shortcuts, Widgets. Additional little things: - Autocomplete for most common headers keys. - Syntax highlighting; Auto formatting. - Optimized for viewing on any device screen. - Cookies. Collect, edit, create. - Request metrics. Measure request duration, response size, status code changing. - History of all request calls. - Request authorisation. Basic Auth with password and username. OAuth with header or query access token.

MQTT Connect is a secure, private client for managing MQTT brokers and clients — built for the people who actually run MQTT infrastructure, not a toy demo app. There's no account, no cloud backend, and nothing phoning home. Every broker profile, client, credential and certificate you add is encrypted and stored only on your device. MQTT Connect only ever talks to the brokers your clients are configured to connect to. SECURE BY DESIGN • Broker profiles, clients, credentials and certificates encrypted at rest in your device's keychain • Face ID / biometric lock, auto-lock, and payload hiding in the app switcher • Full mutual TLS (mTLS): import CA certificates, client certificates and private keys from PEM, paste them directly, or unlock a .p12 bundle in one step • Zero analytics, zero crash reporters, zero telemetry — offline-first by default BUILT FOR REAL MQTT WORK • Save a broker's host, port and transport once, then create as many clients as you need — each with its own ID, auth and certificates • Full support for MQTT 3.1.1 and 5.0 over TCP, TLS, WS and WSS • A live message feed for every client — expand any message for QoS, retain flag and payload, and re-send or edit-and-send instantly • A publish composer with JSON, text and Base64 payloads, topic autocomplete from your history, and pinned snippets for frequent sends • Smart topic suggestions drawn from what you've already subscribed to or published, per client YOUR DATA, YOUR DEVICE Export your client configuration without secrets to move between devices, or erase everything permanently with one tap. Because MQTT Connect holds no copy of your data, that erase is final — and that's the point. Whether you're debugging a broker in production, monitoring sensors on a home network, or testing firmware over MQTT, MQTT Connect keeps your connections fast, your credentials private, and your device the only place any of it lives.
