Agentic Ledger

Runtime observability for AI agents - see exactly what your agent did, why it did it, and what it cost.

Website: agentic-ledger.dev

The numbers are meant to match your provider bill. If they don't, that's a bug we want.

Works with any agent framework, any LLM provider, any model gateway. Zero code changes required. Point your agent at the proxy and everything is captured automatically.

How it works

Agentic Ledger runs as a transparent proxy between your agent and the LLM provider. It intercepts every request and response, assigns it an action_id, stores it, and returns the upstream response unmodified. Your agent never knows the proxy is there. The full picture, with diagrams and a module map for contributors, lives in ARCHITECTURE.md.

Quick Start

Step 1 - Start the proxy

Coming from Helicone or LangSmith? The migration page does the translation in two lines. Running a context compressor like Headroom? They chain.

Two commands, zero config, no terminal held hostage:

uv tool install agentic-ledger    # or: pipx install agentic-ledger, or pip install -U agentic-ledger
agenticledger start     # runs in the background; terminal freed

A tool-managed install (uv tool / pipx) gets its own isolated environment and one unambiguous shim on PATH, so shadowing by another Python's copy becomes rare and doctor-detectable, and agenticledger upgrade always means exactly one thing. Plain pip works too; if a machine ever grows competing installs, agenticledger doctor --fix untangles them.

agenticledger start prints the dashboard URL and gives your terminal back - closing the window doesn't stop it. agenticledger status tells you it's up and healthy, agenticledger logs shows what it's doing, agenticledger stop shuts it down. Want a config file anyway? agenticledger init writes a commented one; see Configuration for what goes in it.
