Open-source proxy to track Claude API costs by team
Drop-in Claude API proxy with real-time cost dashboard—but Anthropic's own billing UI exists.
Watchtower — monitor, inspect, and debug all API traffic between AI coding agents (Claude Code, Codex CLI) and their APIs, with a real-time web dashboard.
DevTools for Claude Code and Codex CLI; solves visibility gap in opaque AI agent workflows.
Developers debugging AI agent behavior, token usage, rate limits, and API interactions

Drop-in Claude API proxy with real-time cost dashboard—but Anthropic's own billing UI exists.
Run Claude Code CLI with ChatGPT subscription, bypassing Anthropic's tighter usage limits.
Reverse proxy lets Claude compress its own context before hitting the API.
Diff-based file reads and conversation deduplication slash token bills by 40%.
Hook-enforced multi-model delegation, but still early and depends on unstable AI API availability.
Instead of wrestling with raw mitmproxy output, this tool gives a purpose-built UI that shows system prompts, tool definitions, token accounting, streaming responses and tool calls — all in real time. The one-liner shell setup, keyboard shortcuts, and token breakdown make debugging Claude Code conversations startlingly quicker, though it’s inherently a local MITM (trust the generated CA) and is narrow by design to Anthropic’s workflow.
