Reactotron is a desktop debugger for React and React Native applications on macOS, Linux, and Windows. It can display application state, API requests and responses, logs, global errors, and quick performance benchmarks, while also subscribing to or replacing selected state. The integration is added as a development dependency and is not included in production builds.

React Native Debugger combines the legacy remote debugger with React Inspector, Redux DevTools, and Apollo Client DevTools in a standalone app. It is intended for older Remote Debugger workflows and does not currently support Hermes, JSI, or React Native's New Architecture.

Altair GraphQL Client is a cross-platform GraphQL client IDE for debugging queries and GraphQL implementations. It is available through desktop applications and browser extensions, giving developers a dedicated interface for investigating query-related issues. Its role is client-side development and debugging, not running a GraphQL server.

MQTTX presents MQTT testing in a chat-like interface where several client connections can stay online at the same time. It helps verify connection, publish, and subscribe behavior over MQTT/TCP, MQTT/TLS, and MQTT/WebSocket while formatting message payloads for inspection. The desktop client runs on Windows, macOS, and Linux and can connect to EMQX or other brokers.
