IntelliJ IDEA review

IntelliJ IDEA is JetBrains’ IDE for Java and Kotlin development. JetBrains says its IDEs support a wide variety of languages and frameworks out of the box, with code-aware navigation and suggestions based on the code you’re working in. The homepage does not list every supported language or framework, so check the current compatibility details before treating it as a general-purpose IDE for your stack.

The core pitch is keeping common development work in one application: JetBrains says you can run, debug, and test applications without leaving the IDE. It also says you can customize the environment to match your preferences. That gives Java and Kotlin developers an integrated place to work across code navigation, execution, debugging, and tests, rather than stitching together separate tools. The value depends on whether those built-in workflows fit your projects; the homepage’s broad feature claims do not specify every plan’s exact feature set.

The clearest fit is Java and Kotlin work where code navigation, debugging, and running tests are part of the daily loop. JetBrains says the IDE uses knowledge of your code to offer navigation and relevant suggestions, and includes tools to run, debug, and test applications. Its homepage also emphasizes that supported languages and frameworks are available without plugin setup.

Users on Reddit point to practical debugging and editing features beyond that general pitch. In one r/java thread, commenters describe evaluating expressions while paused in a debugger, dropping back to an earlier stack frame, and editing multiple occurrences at once. Those are user reports, not a guarantee that every workflow or project will benefit equally. Another commenter values navigating dependencies and code references, and configuring separate runners for unit and integration tests.

There is also a free option: the pricing information lists a Core Edition at $0 for commercial and non-commercial use, plus a 30-day trial for Ultimate plans. For developers who need paid tools, the individual Ultimate plan starts at $16.58 per month when billed annually, with a listed monthly option of $19.90.

The paid-plan rules matter. Individual Ultimate is for personal use only and cannot be reimbursed, so it is not the right license for a company-paid commercial seat. The listed individual price is $199 for the first year, then $159 in year two and $119 from year three with continuity discounts; annual billing is required for those figures. Organizations pay $59.92 per user per month annually or $71.90 monthly, with one named commercial license per user.

The free plan’s seat and usage limits are not published. Its listed AI Free allowance is three credits per 30 days; additional AI credits cost $1 each. JetBrains AI Pro for individual Ultimate is listed at $10 monthly or $100 annually, while organization AI add-on prices are not published. The Ultimate organization trial is 30 days, with teams able to request up to 45 days.

IntelliJ IDEA may also be more than a mixed-stack developer needs. A Reddit discussion includes users who prefer VS Code or separate JetBrains IDEs for other languages. The homepage’s broad language-support claim does not provide a full compatibility list, so confirm your particular stack before switching.

The free Core edition costs $0 and is listed for commercial and non-commercial use. Its seat and usage limits are not published; AI Free includes 3 credits every 30 days.

Ultimate for individuals costs $19.90 monthly or $16.58 per month on annual billing ($199 for the first year). The annual price drops to $159 in year two and $119 from year three. But this license is for personal use only and cannot be reimbursed, which rules it out for some work setups.

Organizations pay $71.90 per user monthly or $59.92 per user monthly on annual billing. That per-user commercial plan includes AI Free. Both Ultimate plans list a 30-day trial; teams can request up to 45 days.

JetBrains AI Pro for individual Ultimate adds $10 monthly or $100 yearly. AI credit top-ups cost $1 per credit; organization AI add-on prices are not published. All Products Pack costs more—$29.90 monthly for individuals or $97.90 per user for organizations—so compare its bundled tools with buying only IntelliJ IDEA. Annual prices are billed yearly.

Switching effort depends on how much of your setup relies on IntelliJ IDEA-specific configuration. JetBrains describes the IDE as supporting Java and Kotlin, plus a wide range of languages and frameworks, with code-aware navigation and built-in run, debug, and test tools. Before moving, check that your target IDE supports the languages, frameworks, and workflows your projects use. The published material does not document settings or project export, so we can’t confirm what transfers automatically.

The same caution applies if you leave: export options and lock-in details are not published in the material we have. Keep a record of important configuration and verify how your project files work in the alternative IDE before switching fully. We also don’t have Reddit posts or comments in the published sources, so we can’t responsibly say what users there report as common reasons for leaving. The clearest trade-offs in the available information are price, unpublished free-tier limits, and whether you need IntelliJ IDEA’s Java and Kotlin focus or JetBrains’ broader tool bundle.
