How this directory works

No paid ranking. Vendors cannot pay to be listed, ranked or reviewed here, and the API reviews carry no affiliate links. Where we work with a vendor, its page says so.

  • Every price, limit and endpoint on an API review is read from the vendor's own pricing page and API docs, and each review shows the date we checked it.
  • Monthly and annual prices are shown apart, with the billing basis on every plan, so two tools are never compared on different bases.
  • Prices older than 120 days are hidden until they are checked again.
