About AsyncAPI-Directory and

Our goal is to create the most comprehensive, standards-compliant and up-to-date directory of machine-readable AsyncAPI definitions with the following principles:

  • Open source, community driven project.
  • Only publicly available APIs (free or paid).
  • Anyone can add or change an API, not only API owners.
  • All data can be accessed through a simple REST API returning JSON.
