Pricing
The tool is free.
The savings are not.
The hosted cloud is free and the code is open source under the MIT License — no tiers, no seat limits, no paywalled features. You pay nothing; you keep everything you save.
Estimate what you'll recover
Because the real question isn't what AgentCost costs — it's what your untracked spend does.
Most recoverable spend comes from right-sizing over-powered models and caching repeated prompts — the two levers AgentCost surfaces for you automatically.
Estimated savings
$750 / mo
≈ $9,000 per year recovered
Illustrative estimate — actual savings depend on your models, traffic, and prompt patterns. AgentCost shows you the specific opportunities; you decide what to act on.
