I use Spring.io to build scalable and secure Java backend applications with Spring Boot. I like Spring.io's powerful ecosystem and developer-friendly features. The auto-configuration and starter dependencies make project setup fast and efficient. Spring Data JPA, Spring Security, and REST support simplify backend development. The framework is highly scalable, well-documented, and widely used in the industry, making it ideal for building enterprise-level applications. The initial setup was smooth and efficient, especially with Spring Initializr, which simplifies project creation. Review collected by and hosted on G2.com.

While Spring.io is powerful, its extensive ecosystem can be overwhelming for beginners. Understanding configurations, annotations, and internal working requires time. Additionally, debugging issues related to auto-configuration or dependency conflicts can be complex. Improving simplicity for new developers and providing clearer debugging insights would make it even better. Review collected by and hosted on G2.com.
