Sagan is the Spring team's own web application that powered the spring.io website, including its blog and guides, built with Spring Boot as a real-world reference application. The repository is now archived and no longer used in production, but remains available as a learning resource for seeing how the Spring team built a production app.
Use cases
- study how the Spring team builds real-world Spring Boot applications
- learn best practices for a production Spring web application
- see how a content-driven site with blog and guides is implemented in Spring
- find example code for Spring MVC, security, and data access patterns
- self-host a Spring-based content website as a starting point
When to choose
- you want a comprehensive, real-world Spring Boot reference codebase to learn from
- you are building a content-driven website (blog, guides, docs) with Spring
- you want to see idiomatic usage of Spring MVC, Spring Security, and Spring Data together
When to avoid
- you need a maintained, production-ready CMS or website platform - the project is archived
- you want a minimal starter template - it is a large full application, not a boilerplate
- you need the current spring.io site features - production no longer uses this code
