Reddit r/AI_Agents Tools

Summary

Tether is a local proxy for macOS that captures every LLM call and visualizes them as a live node graph, enabling time-travel debugging.

Spent too much time parsing logs to understand where my agent failed. Built Tether: a local proxy that captures every LLM call and renders it as a live node graph. You see: - Each API call as a node (color-coded by success/cache/error) - Exact latency and token cost per step - Time-travel mode: edit any node's response and replay the chain from there No cloud, no account. Everything stays on your Mac.
