inspector

Langfuse helps teams instrument LLM applications so they can inspect traces, sessions, retrieval steps, prompts, scores, and evaluations in one place. It also supports prompt versioning, datasets, playground experiments, and integrations with common SDKs and frameworks. You can use the hosted service or self-host with Docker Compose or Kubernetes. Self-hosted instances send basic usage telemetry by default, but it excludes raw traces and can be disabled.

Use Hoppscotch to send REST, GraphQL, WebSocket, and other API requests from the web app, desktop client, or CLI. Collections, environments, scripts, and response tests turn one-off calls into repeatable workflows, while data can remain in a local session, sync through the hosted service, or run on a self-hosted deployment.

ESPConnect uses Web Serial or WebUSB in a modern Chromium browser to inspect ESP32 hardware and partitions, manage filesystems, back up flash, deploy firmware, and open a serial console without a desktop installation. Other applications using the same USB serial bridge must be closed before connecting. ESP8266 support is limited, and the NVS inspector remains an experimental, read-only debugging tool whose parsed output may not cover every edge case.

This skill lets Claude create and execute Playwright automation for page tests, multi-step flows, and browser validation instead of relying on fixed scripts. The browser is visible by default, common interactions have helpers, and a universal executor handles module resolution; it can be installed as a Claude Code plugin or standalone skill.
