Working with AI coding agents every day makes one question surprisingly hard to answer: what is this actually costing right now? Live Tokens answers it at a glance — a local dashboard that turns the usage logs agents already write to disk into live cost and token analytics.
The moment new usage is logged, the dashboard updates — no refresh, no polling. Built at Tabflows with TypeScript and Bun, it runs entirely on your machine and streams updates to the browser over Server-Sent Events.
Features
- Live hero card: today or the current 5-hour billing block — cost, tokens, and burn rate at a glance
- Hourly charts for the current day and a 30-day cost history with per-model breakdowns
- Session rate-limit tracking for every connected account, with usage and reset times
- Instant updates over Server-Sent Events the moment new usage hits the logs
- Local-first: reads usage data from disk and keeps everything on your machine
