Spring Boot review
A free, Java-focused backend framework with embedded servers and production operations built in.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Spring Boot is an open-source Java framework for creating stand-alone applications built on the Spring platform. It is aimed at teams developing backend services that need a practical path from application code to deployable artifacts. Its company-size fit spans small, mid-market, and enterprise organizations, while its backend focus makes it more relevant to service development than to frontend application work.
Spring Boot is free and distributed under the Apache 2.0 license. Its setup model centers on starter dependencies that simplify build configuration and automatic configuration for Spring and third-party libraries. Teams can run applications with embedded Tomcat, Jetty, or Undertow servers, package them as executable JARs, or use traditional WAR deployments. Externalized configuration supports keeping deployment-specific settings outside the application package. These options suit teams that want a consistent Java application structure without assembling server and library configuration from scratch.
Its strongest operational angle is the set of production-oriented features included in the framework: health checks, metrics, and monitoring or management through HTTP endpoints or JMX. Those capabilities give backend teams defined hooks for observing application state and operating services after deployment. Spring Boot is a strong fit for Java teams that want Spring-based services with built-in deployment and management patterns. Teams building primarily in another language, focusing on frontend frameworks, or seeking documented AI features should choose a different framework better aligned with those needs.
Spring Boot pros and cons
- Where it wins
- Embedded Tomcat, Jetty, or Undertow servers simplify deployment.
- Starter dependencies and automatic configuration reduce setup work.
- Health checks, metrics, and management endpoints support operations.
- Where it doesn't
- Designed for backend applications rather than frontend frameworks.
- Primary language support is Java, limiting fit for other language teams.
- The stated feature set does not include AI capabilities.
