Apache Camel is an open-source integration framework built on the well-known Enterprise Integration Patterns. Developers define routing and mediation rules between systems in Java, YAML or XML and use URIs and one API to connect to transports and messaging systems such as HTTP, Kafka, JMS and AWS S3. Camel provides many connectors and can be embedded as a small library in a Java application, run on Spring Boot or Quarkus, or run standalone with the Camel CLI. It is software you operate yourself, not a hosted service.
Apache Camel is developed under the Apache Software Foundation, a US non-profit (501(c)(3)), and licensed under the Apache License 2.0. There is no vendor-operated cloud and no data passes through the project: where data is processed depends only on where you run your own Camel applications. Community support is volunteer-based; commercial support comes from other companies. For a European organisation this means full control over hosting, jurisdiction and updates, at the cost of operating the integration layer yourself or buying support.
