Project overview

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.

claude-devtools

@matt1398·TypeScript

Inspect Claude Code sessions, tool calls, subagents, and context usage in a visual UI.

Project overview

claude-devtools reads the Claude Code logs and transcripts already stored under `~/.claude/` and reconstructs file reads, searches, edits, tool inputs and outputs, subagent execution trees, and per-turn token attribution. It helps you investigate what an agent actually did and why context usage grew without rerunning the original task.
