How we rank

Every tool in a category is ranked by the same rule, worked out from the data we hold, not by who pays us. In order:

  1. How many of the category's shared features it has.
  2. Whether there is a free plan to start on.
  3. How open it is to AI: an API and an MCP server.
  4. Whether its pricing is public.
  5. Name, A to Z, when all else is equal.

When we add a tool or learn more about one, the ranking updates by itself.
