IntelliJ IDEA: Pricing, Features & Alternatives

IntelliJ IDEA is still the IDE that understands a codebase rather than just editing its files. Its refactoring, inspections and debugger for Java, Kotlin and Spring are ahead of anything built on a language server. Since 2025.3 the Community and Ultimate editions are one product. The free tier is licensed for commercial use and now includes basic database tools, Kubernetes support and non-JVM languages. Ultimate unlocks Spring, enterprise frameworks, profilers and full web tooling. It costs $719 per user per year for organisations, or $199 for an individual's first year (falling to $159, then $119, with continuous renewal). The All Products Pack is $979.
