Your AI costs are
killing your margins.

Your OpenAI bill tells you nothing about which users cost more than they pay. This does.

What CostCanary does

AI cost monitoring features built for SaaS

One SDK wraps your existing LLM calls. No proxies, no infra changes.

Per-user cost tracking

Every LLM call is tagged to a real user ID so you see exactly who's burning your margins, not just aggregate numbers nobody acts on.

Profitability alerts

"Notify me when a user burns 80% of their subscription revenue." That kind of alert.

Feature-level breakdown

Your chat feature costs 6× more than translate. You wouldn't know that from an OpenAI invoice. CostCanary breaks it down by feature so you can actually do something about it.

Weekly profit digest

Monday morning. One email. Your 3 most unprofitable users, your top cost driver, one thing to fix. Done.

Industry benchmarks

Are you overpaying per call or is everyone paying that much? Anonymous aggregate data from real AI SaaS products, updated weekly.

VS Code integration

Inline cost annotations right in your editor, on every AI call, as you write code.

What developers are saying

We had no idea our /summarize endpoint was 8× more expensive per user than /chat. Found it in the first hour.

Literally two lines. Wrapped our OpenAI client, deployed, and had per-user costs in Slack by lunch.

The Monday email told me to switch one feature from GPT-4o to Claude Haiku. Saved us $200/mo, took 10 minutes.

The Monday Morning Brief

Every Monday.

In your inbox.

Not a dashboard you'll forget to check. A weekly briefing engineered to make you act.

Before you integrate

Your margins won't
protect themselves.

Right now, some of your users cost more than they pay you. You just can't see which ones. Few lines of code fixes that.
