About AI Stack Prices

AI Stack Prices shows what AI app builders and voice-agent platforms really cost, so you can compare them before you sign up.

Every price is copied by hand from the vendor's official pricing page, with the date we checked it. Our calculators only use those published numbers. Where a vendor publishes a range or leaves something out, we say so instead of guessing.

A script reads each official pricing page every day and flags any change. A person checks the change and then updates this site.

We are independent and not affiliated with any company listed. If we join a company's affiliate program, links to it will say so next to the link. That never changes the prices we show.
