What is ManagePrompt?
ManagePrompt is a local LLM call debugger that records every API request and response during development. It displays full request and response bodies with a visual flow map, tracks input, output, and cache tokens for each call, and estimates real‑time cost using up‑to‑date pricing data.
The tool captures both streaming and non‑streaming calls and updates a live WebSocket‑powered UI as calls occur. Project‑scoped SQLite databases are created automatically, requiring no configuration. Integration is straightforward, add the npm package and wrap your language model with the provided middleware, or use the capture helper to wrap any LLM API such as OpenAI, Anthropic, Google, or Mistral.
