Most LLM cost trackers work the same way: send all your prompts to their cloud, they analyze them, and charge you $20-200/mo for the privilege.
I didn't want to trust a third party with every message I send to ChatGPT, Claude, or my local models.
So I built Token Guard. A local-only API gateway that runs in your system tray, proxies your LLM requests, logs every token to SQLite, and shows you a dashboard all on your own machine. Zero telemetry. Zero cloud.

How it works:
1. Point your apps (OpenAI SDK, curl, anything) http://localhost:8080
2. Token Guard forwards to any provider OpenAI, Anthropic, Google, OpenRouter, Ollama, vLLM
3. Every request is logged: tokens used, cost, latency, model
4. See it all in a clean dashboard
That's it. No setup script. No Docker. No cloud dependency.

The format conversion is the magic part.
You can use the OpenAI SDK to call Claude. Or the Anthropic SDK to call Gemini. Or any combination of the 3 3 matrix. Token Guard converts requests and responses between OpenAI, Anthropic, and Google formats automatically.
Vision, tools, streaming all converted on the fly.

Built with:
Tauri + Rust (2MB binary, <100MB RAM)
React + Tailwind CSS for the UI
SQLite for local storage
OS keychain for API keys (they never touch disk)
Desktop app for Windows, macOS, and Linux. One binary, no runtime.

Pricing:
Core: free and open source (Apache 2.0)
-
Pro license ($4.99 one-time, lifetime): removes the support banner, enables auto-updates
No subscription. No upsells. No data collection. Just a one-time "thanks for supporting the project" button.
6/9
Who's this for?
Anyone using LLMs through an API and wondering where the money goes
Self-hosting enthusiasts who keep everything local
Developers who want one dashboard across every provider
People tired of cloud monitoring tools that cost more than the API calls themselves

I'm 12 years old. I built this solo Rust backend, React frontend, Tauri desktop shell, Cloudflare Workers for licensing, Paddle for payments.
I started because I couldn't find a cost tracker that didn't send my data to someone else's server. So I built one.

It's not perfect. Provider presets could be smoother. The Google Gemini auth needs a fix. But the core loop works: set up the proxy call any LLM see instant cost tracking.
If you try it and something breaks, tell me. I ship fixes fast.

No cloud. No telemetry. Just your tokens, tracked locally.
