# TokenBeaver

> TokenBeaver is an AI cost gateway for developers. It installs as a VS Code extension and runs a local gateway that sits between your AI coding agent and the model provider, trimming wasted tokens before they reach your bill. Internal testing shows 40–70% lower API spend. It is local-first: your prompts, code, and API keys never leave your machine.

## What it does

- Optimizes both the input and output of AI coding requests, alongside context and cache, so each request carries fewer tokens while returning the same answer.
- Runs as a local gateway (default Base URL http://127.0.0.1:4505/v1) that you point your coding tool at, using your own API key — TokenBeaver forwards it unchanged.
- Fail-open architecture: if the gateway is unavailable, requests pass through normally rather than breaking your workflow.

## Key facts

- Pricing: Free tier includes 20 optimizations per month with full feature access. Pro is $15/month or $100/year (about $8.33/month) with unlimited optimizations and a 14-day free trial. No credit card required to start.
- Privacy: Local-first by design. Prompts, code, and provider keys stay on the user's machine. TokenBeaver never proxies billing or touches the user's model account.
- Measured impact: 40–70% lower API spend and 15–25% more usable Claude Code quota in a 5-hour rolling window, depending on session length, model, workload, and number of sub-agents (figures from internal testing).
