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

Track per-user costs. Enforce budgets. Simulate pricing changes. Fix the problem, not just report it.

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.

Feature-level breakdown

Your chat feature costs 6x more than translate. You wouldn't know that from an OpenAI invoice. CostCanary breaks it down by feature per user.

Budget enforcement

Set per-user monthly spend limits. When exceeded, warn via callback or block the LLM call before it executes. Stop margin bleed in real time.

Overage billing

See which users cost more than they pay. Get ready-to-use Stripe code to charge them for the overage. Turn unprofitable users into revenue.

Pricing simulator

"What if I charge $0.01 per token above 10K?" Run what-if scenarios against your real usage data. See projected revenue and margin changes per user.

Alerts and weekly digest

Profitability alerts when users cross thresholds. Monday email with your 3 worst users, top cost driver, and one thing to fix. Benchmarks vs industry.

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.”

“Set a $50/month budget per user. Next day the SDK blocked a power user before they burned another $80. Paid for itself instantly.”

@marcusdev
backend eng at an edtech startup

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

Other tools show the fire.

CostCanary puts it out.

Langfuse and Helicone track costs. LiteLLM enforces budgets. Nobody helps you reprice, charge overages, or simulate what your pricing should be. CostCanary does.

Track

Per-user, per-feature cost attribution across 10+ LLM providers

Enforce

Set monthly budgets. Warn or block users before they burn your margins

Fix

Simulate pricing models. Charge overages via Stripe. Turn cost data into revenue

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.
