How it works

Connect

Add your Anthropic Admin API key. We encrypt it at rest and never log it. Read-only access only.

Set a budget

Define your monthly spend limit. $50, $200, whatever fits your workflow.

Get alerted

We check your usage every 6 hours. When you hit 70%, 90%, or 100% of your limit, you get a notification via Discord or email.

Why I built this

I'm one developer, and I built Arometer because I opened my Anthropic bill one morning and did a double take.

I'd been shipping all month, and somewhere in those API calls the spend had quietly grown into a number I didn't expect. No warning, no nudge — just the bill.

That night I hacked together a script to watch usage in real time, then gave it a budget, then alerts at 70%, 90%, and 100%. Arometer is that script made proper — so nobody else gets surprised by their own bill.
