About
Bernn — one glance at everything you're burning.
You're paying AWS, Anthropic, and OpenAI separately, and none of them talk to each other. Bernn pulls all of it into one running total, tells you the moment you cross a budget you set, and does it from your pocket instead of three browser tabs
CONNECT YOUR ACCOUNTS
• Anthropic — paste an Admin API key, about a minute
• AWS — create a read-only IAM role from a template we give you (automatic CloudFormation setup or a manual walkthrough, your choice), about five minutes
• OpenAI — admin key or CSV import
• Track multiple accounts per provider (Pro) — a work and a personal AWS account both show up separately
SEE THE WHOLE PICTURE
• One total spend figure across every connected account
• Per-provider breakdown, and per-service or per-model detail
• Spend trend by day, month, year, or lifetime
• Pull to refresh; data also refreshes on its own every hour
GET TOLD BEFORE THE BILL
• Budget alerts — tell Bernn when this month passes $200, per provider or overall
• Anomaly alerts — tell Bernn when today jumps more than 50% above your recent average
• Push notifications, with optional repeat reminders for alerts you can't afford to miss
READ-ONLY. ALWAYS.
Bernn asks for billing-read access only. It cannot launch, change, or spend anything on your account. AWS access uses a proper cross-account role with a unique ID per connection — the pattern AWS itself recommends — not access keys. Credentials are encrypted before storage and never shown to you again after you add them.
YOUR DATA, YOUR CONTROL
• Export everything Bernn holds about you as a file, anytime
• Delete your account and all data in-app, immediately, no support ticket needed
• Notification switches that actually stop delivery server-side
PRICING
• Free — one tracker, no custom alerts
• Monthly — $4.99/month
• Yearly — $48/year (save 20%)
• Lifetime — $150 once, never expires
Bernn is a visibility tool. It shows you what you're spending — it doesn't manage or optimize spend for you, and figures are refreshed hourly, not real-time (providers' own billing data lags by design).
