About IntelliJ IDEA

IntelliJ IDEA is JetBrains' integrated development environment for Java and Kotlin development. Since version 2025.3, JetBrains has distributed IntelliJ IDEA as one unified product: core functionality remains free for commercial and non-commercial work, while an Ultimate subscription unlocks advanced professional features. This page focuses on IntelliJ IDEA itself, including its 2026 feature set, pricing model, AI integration, development workflows, limitations, and alternatives.

What is included in IntelliJ IDEA without a subscription?

The unified IntelliJ IDEA gives developers a functional free IDE rather than a limited trial that stops working. Core Java and Kotlin development remains available without an Ultimate subscription, and JetBrains expanded the free baseline when it replaced the former separate Community and Ultimate distributions with a single installer.

The free product includes editing, navigation, refactoring, version-control workflows, debugging, project tools, and a broader set of language and development features than the old Community Edition. JetBrains still reserves advanced capabilities for Ultimate, but teams can install the same product and decide later whether the paid feature set is worth unlocking.

What does IntelliJ IDEA Ultimate add?

Ultimate is aimed at professional developers who need deeper framework, database, web, enterprise, and tooling support. Its value is strongest for teams working with complex JVM applications, Spring, database-heavy systems, web technologies, enterprise frameworks, and projects that benefit from integrated inspections, navigation, profiling, deployment, or framework awareness.

The exact boundary between free and Ultimate features can change as JetBrains expands the unified distribution. Buyers should therefore evaluate the current feature matrix instead of relying on older Community-versus-Ultimate comparisons that predate the 2025.3 distribution change.

What changed in IntelliJ IDEA 2026.2?

IntelliJ IDEA 2026.2 adds day-one support for Java 27 and stable Kotlin 2.4 features. JetBrains also added native GitHub Copilot integration, agent skills, AI completion support for third-party providers, logpoints, dependency completion, early Gradle 10 support and migration assistance, a streamlined Git conflict-resolution flow, Docker Compose improvements, Spring enhancements, Terraform testing support, and TypeScript 7.0 support.

JetBrains released IntelliJ IDEA 2026.2.1 in August 2026 as the first maintenance update for the 2026.2 line. That update fixed issues around shell-script execution in Markdown, undo behavior, terminal tabs, Mercurial conflict resolution, and Java code formatting. Buyers evaluating current compatibility should use the latest maintenance build rather than treating the initial 2026.2 release as the final state of the branch.

How does AI work inside IntelliJ IDEA?

JetBrains AI is integrated into IntelliJ IDEA through AI Assistant and agent workflows. AI Assistant can provide contextual chat, code completion, explanations, documentation help, commit-message generation, and other coding assistance. JetBrains also supports Junie, its coding agent for multi-step work such as editing files, running tests, using terminal commands, and working with project context.

IntelliJ IDEA is not limited to JetBrains' own agent. Current documentation describes support for agents such as Junie, Claude Agent, Codex, and GitHub Copilot, plus external agents that support the Agent Client Protocol. MCP can extend agents with external tools and data sources. Developers can use JetBrains AI subscriptions, provider accounts, bring-your-own-key setups, or local models where supported. This gives teams more model choice, but it also means security and data-flow reviews should account for whichever provider or agent is actually enabled.

How much does IntelliJ IDEA cost in August 2026?

Pricing checked on August 22, 2026 against JetBrains' official IntelliJ IDEA subscription page. IntelliJ IDEA can be downloaded and used with its free core functionality, and new installations include a 30-day Ultimate trial. The current organization pricing page lists IntelliJ IDEA Ultimate at $200 per user per year for yearly billing. JetBrains also offers individual pricing and renewal structures that differ from organization licensing.

The All Products Pack is another option for developers who need several JetBrains IDEs. JetBrains currently lists the organization All Products Pack at $979 per user per year and includes a larger set of IDEs, .NET tools, JetBrains AI Pro, and other tools. These figures are list prices and taxes or regional rules can affect the final amount. Teams should compare one IntelliJ IDEA license with the All Products Pack based on actual tool usage rather than assuming the bundle is automatically cheaper.

What development workflows does IntelliJ IDEA cover?

IntelliJ IDEA combines code editing with project navigation, refactoring, build-tool integration, testing, debugging, version control, terminal workflows, database access, framework support, Docker-related development, and plugin extensions. This can reduce context switching for developers who would otherwise combine several standalone tools.

The benefit is greatest when the IDE understands the project's language, framework, and build system deeply enough to provide reliable navigation, inspections, code transformations, and debugging context. Teams that use only a narrow editor plus command-line tools may not need this level of integration.

What are IntelliJ IDEA's main limitations?

IntelliJ IDEA is a substantial desktop IDE and can use more memory and system resources than lightweight editors. Large projects, many plugins, heavy indexing, local services, and multiple development environments can increase hardware requirements. Teams standardizing on IntelliJ IDEA should test representative codebases and developer machines rather than assuming one configuration will fit every project.

The product can also become complex when many plugins, AI agents, framework integrations, and custom settings are enabled. Plugin governance and consistent team configuration become more important in larger organizations. Some developers may prefer a lighter editor, a terminal-first workflow, or a browser-based environment even when IntelliJ IDEA offers deeper integrated tooling.

How does IntelliJ IDEA compare with alternatives?

Visual Studio Code is a common alternative for developers who prefer a lightweight, extension-driven editor and want broad language flexibility. Eclipse remains relevant for Java teams that prefer its open ecosystem and established enterprise tooling. Visual Studio is a stronger fit for some Microsoft-centric .NET workloads, while Android Studio is the natural choice for Android-focused development and itself builds on JetBrains technology.

AI-first editors and agents such as Cursor, GitHub Copilot, Claude Code, and OpenAI Codex may also compete for parts of the development workflow. IntelliJ IDEA's advantage is the depth of language-aware IDE functionality and its ability to host several AI agents inside an established development environment. The trade-off is that developers who primarily want agent-driven coding with minimal traditional IDE interaction may prefer a simpler or more AI-native setup.

Who should consider another product instead of IntelliJ IDEA?

A developer should consider another tool if the project does not benefit from deep Java or Kotlin support, if the team strongly prefers lightweight editors, if local hardware is constrained, or if browser-based development is a requirement. Teams standardized on another IDE may also gain little from adding IntelliJ IDEA unless it solves a specific workflow problem.

IntelliJ IDEA is most compelling when developers need robust Java and Kotlin tooling, refactoring, debugging, framework support, project intelligence, and a mature plugin ecosystem in one environment. The buying decision should be based on those needs rather than on the assumption that a full-featured IDE is automatically better for every developer.
