camel

Apache Camel is a mature, open-source integration framework (Apache License 2.0) that has been in production since 2007, used by thousands of companies. It provides over 350 connectors to connect to databases, APIs, message brokers, and cloud services like Kafka, REST, JDBC, AWS, Azure, GCP, and Salesforce. **Key Features:** - **Flexible Route Definition:** Write integration routes in Java, YAML, or XML, allowing teams to choose the language that fits their workflow. - **Multiple Runtimes:** Run Camel on Spring Boot (with starters for all connectors), Quarkus (cloud-native with fast startup and low memory), or standalone via the Camel CLI. Other runtimes include Camel K for Kubernetes, Camel Karaf for OSGi, and Camel Kafka Connector for Kafka Connect. - **Enterprise Integration Patterns (EIPs):** Includes a comprehensive set of patterns for message routing, transformation, and mediation. - **AI Integration:** Provides an MCP (Model Context Protocol) server for AI coding assistants like Claude Code, GitHub Copilot, Cursor, and Gemini CLI, giving them full Camel catalog context. Also includes components for LangChain4j and OpenAI, and supports the A2A agent-to-agent protocol. - **Visual Designers:** Integrates with Kaoto (open-source drag-and-drop designer) and Karavan (VS Code and standalone visual designer). **Getting Started:** - Quick start with CLI: `camel init hello.yaml` and `camel run hello.yaml`. - Add to existing Spring Boot projects via Maven dependency `camel-spring-boot-starter`. **Community and Resources:** - Extensive documentation, examples (CLI, standalone, Spring Boot, Quarkus), and tooling available on the official website. - Active community with mailing list, Zulip chat, and Stack Overflow support. **Licensing:** Apache License 2.0.
