Know exactly what
you spend on AI
Real-time Claude and OpenAI cost tracking from your menu bar. Per-session breakdowns, budget alerts, and weekly reports. 100% local — nothing leaves your Mac.
AI costs add up faster than you think
The average developer using Claude Code spends roughly $6 per day, with the top 10% exceeding $12 daily. Over a month, that's $120-250+ — and most developers have no idea until the bill arrives. OpenAI API usage can be equally surprising, especially when using GPT-4 or o1 for complex tasks.
FavTray puts your AI spending right in the menu bar where you can see it as you work. No more end-of-month billing surprises.

Which AI providers does FavTray track?
FavTray tracks Claude (Anthropic) and OpenAI API costs in real time. It reads local usage logs and API data — no proxy setup or SDK integration required.
Is my API key safe?
Yes. FavTray stores API credentials in memory only — never written to disk. All data processing happens locally on your Mac. Nothing is sent to external servers.
How accurate is the cost tracking?
FavTray reads the same usage data that Anthropic and OpenAI use for billing. Costs are calculated using current per-model token pricing, updated with each app release.
Is the AI Usage Tracker free?
The core tracker is free: current session costs, daily totals, and basic limits. Pro unlocks full usage history, advanced spending limits, and multi-provider comparison dashboards.
Do I need to set up anything?
No. FavTray automatically reads Claude usage from ~/.claude/ logs. For OpenAI, you provide your API key once. No webhooks, no proxy, no account creation.
