ESPConnect

Project overview

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.

Project overview

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.
