A lot of IntelliJ IDEA vs WebStorm advice was written before JetBrains merged its editions, so it describes products you can no longer install. What still holds up is the backend question. If the repository has Java or Kotlin in it, go with IntelliJ IDEA. If it’s JavaScript or TypeScript and nothing else, WebStorm.
Frontend tooling isn’t what separates them. JetBrains documents that IntelliJ IDEA Ultimate includes the same JavaScript features as WebStorm, and since version 2026.1 the core JavaScript, TypeScript, HTML and CSS features sit in the free tier (JetBrains, 2026).
IntelliJ IDEA has also been one unified product since version 2025.3, which makes any comparison framed as Community Edition vs Ultimate out of date.
How IntelliJ IDEA and WebStorm Differ in Scope
WebStorm covers JavaScript and TypeScript only. IntelliJ IDEA handles those too, and Java and Kotlin besides.
WebStorm is an IDE built for web development. JetBrains calls it a good fit when most of your work is frontend, and the same documentation admits it does not offer extensive support for backend languages.
Both run on the IntelliJ Platform, the open-source base that also powers Android Studio (JetBrains, 2025). Keymaps, the terminal, version control integration and the HTTP client behave the same in each, per JetBrains’ WebStorm documentation.
| Attribute | IntelliJ IDEA | WebStorm | Edge |
|---|---|---|---|
| Primary languages | Java, Kotlin, plus web languages | JavaScript, TypeScript | Depends on stack |
| JavaScript and TypeScript tooling | Same feature set, partly free since 2026.1 | Full set in one license | Tie on features |
| JVM tooling | Full Java and Kotlin support | Limited backend language support | IntelliJ IDEA |
| Free use | Free core tier, commercial use allowed | Free for non-commercial use only | IntelliJ IDEA |
| Project model | Built on modules | Simplified, no modules | WebStorm |
If your stack is JavaScript or TypeScript only, WebStorm is the one to look at. A Java or Kotlin backend with a web frontend in the same repository points to IntelliJ IDEA. And if your company already pays for several JetBrains IDEs, check the All Products Pack before adding another seat.
Language is the easy part to draw a line on. JavaScript tooling is murkier.
What Changed When IntelliJ IDEA Became One Product?
With version 2025.3 in December 2025, JetBrains replaced IntelliJ IDEA Community Edition and Ultimate with one IntelliJ IDEA installer. Ultimate features unlock with a subscription, and a free 30-day trial runs inside the same IDE (JetBrains help, 2026).
The free tier kept everything Community Edition offered and added more, according to JetBrains’ December 2025 release post. New free items include a Spring Boot project wizard, a database schema viewer, full SQL language support, and syntax highlighting for Spring, Jakarta EE and Thymeleaf.
JavaScript wasn’t in that batch. JetBrains said in July 2025 that JavaScript support would still need Ultimate in 2025.3 and was on track for a later free release.
That release was IntelliJ IDEA 2026.1, announced in March 2026. Core JavaScript, TypeScript, HTML and CSS features moved from Ultimate-only to free, along with basic React (JetBrains IntelliJ IDEA blog).
WebStorm had gone first. It became free for non-commercial use on October 24, 2024 (JetBrains blog), and IntelliJ IDEA opened up its web tooling a year and a half later. Read together, the two moves look like the IDEs converging from opposite ends.
What’s left of the gap is mostly licensing and project fit. Comparison pages that still frame the choice as Community vs Ultimate predate 2025.3 and no longer describe what you install. As of October 2026, current IntelliJ IDEA versions ship as one product.
Does IntelliJ IDEA Ultimate Include Everything WebStorm Has?
For JavaScript and TypeScript, yes. JetBrains’ WebStorm documentation says IntelliJ IDEA Ultimate includes the same features for JavaScript development, available out of the box or through free plugins.
The differences sit elsewhere. WebStorm drops the module concept IntelliJ IDEA relies on, which gives it a simpler project model, per the same documentation.
Some comparison blogs claim WebStorm infers TypeScript types better. JetBrains documents feature parity, so I’d treat that claim as unproven until someone publishes a benchmark.
One dated detail does favor WebStorm on paper. WebStorm 2026.1 (March 2026) switched to a service-powered TypeScript engine by default, which relies on the official TypeScript language service for more accurate type inference and faster analysis in large projects (JetBrains WebStorm blog).
That announcement covers WebStorm only. Check IntelliJ IDEA’s release notes before assuming the same default.
What the Free IntelliJ IDEA Tier Covers for JavaScript
Since IntelliJ IDEA 2026.1, the free tier ships a web toolkit that used to require Ultimate (JetBrains IntelliJ IDEA blog, March 2026).
Basic React support comes with it, including code completion, navigation between components and attributes, and rename refactorings for components and props.
- Full syntax highlighting, code completion, import management and navigation for JavaScript, TypeScript, HTML and CSS
- Inspections and quick fixes, plus duplicate detection
- Rename and Introduce Variable refactorings
- A Vite project generator and NPM scripts from package.json
- Dependency vulnerability checks
Prettier, ESLint, TSLint and StyleLint are integrated as well, so linting support works without installing anything extra.
What Still Needs an Ultimate Subscription
The free tier stops where frontend work gets heavy. JetBrains puts a dedicated JavaScript debugger, test runners and test UI tooling, advanced refactorings, and support for all frontend frameworks (Angular and Vue.js included) in the paid layer.
WebStorm’s single license includes all of it. Its 2026.1 release also added Angular 21 template syntax and an updated Vue TypeScript plugin (JetBrains WebStorm blog, March 2026).
Basic React work fits the free IntelliJ IDEA tier fine. Angular, Vue.js, or anything that leans on the debugger or test runners calls for Ultimate or WebStorm.
Free-tier boundaries moved twice between 2025 and 2026, so confirm against the release notes of the version you install.
How Much Do IntelliJ IDEA and WebStorm Cost?
WebStorm is free for non-commercial use and a paid subscription for commercial work. IntelliJ IDEA has a free core tier for commercial and non-commercial projects, with Ultimate sold as a subscription on top.
JetBrains lists learning, open-source development, content creation and hobby projects as non-commercial. Developing products and earning commercial benefit from the work counts as commercial use (JetBrains, October 2024).
Per JetBrains’ WebStorm licensing FAQ, you get a 30-day trial with full access. After 12 consecutive months of subscription you keep a perpetual fallback for one specific version, and personal subscriptions get 20% off the second year and 40% from the third. Companies cannot buy, refund or finance personal licenses.
A lapsed subscription behaves differently in the two IDEs.
| After a subscription ends | IntelliJ IDEA | WebStorm |
|---|---|---|
| Perpetual fallback version | After 12 consecutive months | After 12 consecutive months |
| Free core tier with updates | Yes, since 2025.2 | Not offered |
| Free option for commercial work | Core features | None |
Prices vary by region, billing period and discount, and third-party price lists contradict each other. Use JetBrains’ own buy pages for the current number.
When the All Products Pack Beats Separate Licenses
When the same developer works on a JVM backend and a web frontend, buy one IntelliJ IDEA Ultimate seat rather than two IDEs. Ultimate carries WebStorm’s JavaScript features, so a second WebStorm license adds nothing.
A single license makes sense for one language family and one IDE. The pack starts paying off once one person needs two or more JetBrains IDEs, say IntelliJ IDEA plus PyCharm or DataGrip. WebStorm is included, and JetBrains lets you move a subscription between IDEs.
Third-party sources quote at least three different individual pack prices. Compare the pack against your own two-IDE total on JetBrains’ buy page.
Students, teachers and content creators can apply for a free All Products Pack license, and startups and non-profits get 50% off (JetBrains WebStorm licensing FAQ).
Which Is Better for Java, Spring Boot and Full-Stack Projects?
IntelliJ IDEA, for the JVM half. Whether the frontend belongs in the same window is the real decision.
For back-end work in Java or Kotlin, IntelliJ IDEA needs one thing WebStorm never asks for, a JDK. JetBrains bundles a runtime to run the IDE itself, but building Java applications requires a standalone JDK (IntelliJ IDEA help, 2026.2).
Spring is a tier question. The Spring plugins are bundled and enabled by default only with an Ultimate subscription, and JetBrains calls Spring support without it limited, per its Spring documentation.
Database work splits the other way. IntelliJ IDEA’s free tier connects to a database and shows its schema, but data and SQL execution need a subscription (JetBrains, July 2025).
WebStorm has bundled the Database Tools and SQL plugin at no extra cost since version 2024.3, and that plugin carries the DataGrip feature set (JetBrains WebStorm blog and help). Before 2024.3 it was a separate paid subscription, so older comparisons get this wrong.
Keeping everything in IntelliJ IDEA means Spring run configurations and npm scripts from package.json live in the same project, under one seat with the Ultimate subscription covering Spring tooling.
Splitting the work across IntelliJ IDEA and WebStorm has its own appeal. The Toolbox App tracks every project and opens each in the right IDE, and frontend developers never have to load JVM tooling. The cost is two licenses, or the All Products Pack.
Packt’s book Full Stack Quarkus and React notes that the Ultimate version works well for both frontend and backend development. In practice, team boundaries settle this before tooling does.
Which Built-In Tools, Plugins and Performance Traits Do They Share?
The tool set is the same. The license tier decides who gets it.
IntelliJ IDEA’s free tier leaves out a few shared tools that WebStorm includes in its single license, per JetBrains’ July 2025 unified-distribution post and its WebStorm documentation.
| Shared tool | IntelliJ IDEA free tier | IntelliJ IDEA Ultimate | WebStorm |
|---|---|---|---|
| HTTP client | Subscribers only | Included | Included |
| Remote development | Subscribers only | Included | Included |
| Database data editor and SQL execution | Schema view only | Included | Included since 2024.3 |
The sources look like they disagree on the HTTP client. The WebStorm documentation lists it among tools that work the same across JetBrains IDEs, while the IntelliJ IDEA announcement lists it as subscriber-only. Both hold, because the tool is identical and only the tier differs.
Plugin Compatibility Between the Two IDEs
Compatibility follows declared dependencies, not the IDE’s name. JetBrains Marketplace reads a plugin’s module dependencies and offers it only to IDEs that carry them (IntelliJ Platform Plugin SDK, updated April 2026).
- Plugins that depend only on the platform load in every IntelliJ Platform IDE, WebStorm and IntelliJ IDEA included.
- Anything that depends on Java loads in IntelliJ IDEA and Android Studio, but not in WebStorm.
- Plugins built on the JavaScript plugin load in WebStorm, and in other IDEs where the JavaScript plugin is installed.
- Legacy plugins that declare no dependencies at all load only in IntelliJ IDEA.
In the unified IntelliJ IDEA, Ultimate-only plugins ship inside the distribution but stay disabled until a subscription is active (JetBrains Platform blog, November 2025).
Before assuming a plugin works in WebStorm, read the compatible products on its Marketplace page.
Startup Time, Memory and Indexing
JetBrains lists the same minimum hardware for both IDEs: 8 GB of total RAM, with 3 GB available to the IDE, plus 4 CPU cores and 10 GB of disk (IntelliJ IDEA and WebStorm 2026.2 help).
That doesn’t support the common claim that WebStorm needs less machine. Review sites don’t settle it either. A StackShare summary calls WebStorm lighter, while TrustRadius reviewers mention high RAM use and slowdowns on very large codebases.
Indexing has been tuned product by product. WebStorm 2024.3 stopped indexing unneeded files in the dist folder to cut CPU use, and JetBrains reported 25% faster multi-threaded indexing in IntelliJ IDEA in November 2024.
Choose on language and license, then measure both on your own repository.
When Is IntelliJ IDEA or WebStorm the Wrong Choice?
WebStorm is wrong the moment the repository needs Java or Kotlin run and debugged. IntelliJ IDEA is wrong when you pay for Ultimate and only ever open JavaScript files.
Multi-module builds are a poor match for WebStorm, since IntelliJ IDEA organizes projects around modules and WebStorm doesn’t use them (JetBrains WebStorm documentation). A Spring-heavy backend needs the Ultimate subscription too, because free-tier Spring support is limited. And plugins that depend on the Java module simply aren’t offered in WebStorm.
Linux users should watch out for Snap installs. JetBrains warns of performance degradation and JavaScript debugging problems with Chromium in both IDEs, and recommends the Toolbox App instead.
The tempting default for a JavaScript-only team is IntelliJ IDEA Ultimate, just in case. Skip it. WebStorm covers the frontend stack, and the JVM tooling would sit unused.
IntelliJ IDEA puts a JVM backend and a web frontend in one project, adds Spring tooling, run configurations and a debugger with Ultimate, and keeps the core tier free for commercial work. The downsides are real, though. Spring, the HTTP client and the database data editor sit behind the subscription, Java work needs a separate JDK, and the module-based project model is heavier than WebStorm’s simplified one.
WebStorm’s case is shorter:
- The Database Tools and SQL plugin has been bundled since 2024.3
- The project model has no modules
- Every feature ships in one license, with no tier to track
- No tooling for running Java or Kotlin code, and plugins that need the Java module are unavailable
How to Choose Between IntelliJ IDEA and WebStorm
Work through the checks below in order and stop at the first one that decides it. For most teams, the first one does.
Write the stack down before opening either IDE, covering languages, build tools and frameworks, in a short web development tech stack list.
- Look at the languages. Any Java or Kotlin in the repository points to IntelliJ IDEA, and JavaScript or TypeScript alone points to WebStorm.
- Check the license type. Commercial work rules out WebStorm’s non-commercial license and brings the free IntelliJ IDEA tier into play.
- See what seats you already have, since an All Products Pack or another JetBrains IDE subscription may cover both.
- Install both through the Toolbox App, open the same project in each, and compare indexing time and memory on your own hardware.
- Note every tool you reached for and could not use, then check the list against JetBrains’ WebStorm vs IntelliJ IDEA Ultimate comparison page.
Revisit the choice at each renewal, and again whenever the stack gains or loses a JVM, Angular or Vue.js component.
JetBrains moved licensing and free-tier boundaries several times between 2024 and 2026, so a decision based on last year’s limits can be wrong today.
IntelliJ IDEA vs WebStorm FAQ
Is WebStorm better than VS Code?
No, not across the board. WebStorm ships JavaScript, TypeScript and integrated developer tools out of the box (JetBrains documentation), while VS Code is the free alternative.
For the full trade-off, see this WebStorm and VS Code comparison.
How do I move my settings and keymap from IntelliJ IDEA to WebStorm?
Import them at the first WebStorm launch, or share them later through Backup and Sync. JetBrains IDEs use the same keymaps, and synced settings cover themes, keymaps, system settings and the list of enabled plugins (WebStorm documentation).
Can I add Java support to WebStorm?
No, JetBrains documents no route for it. WebStorm is built for JavaScript and TypeScript, and Java functionality ships as a plugin whose compatibility list names IntelliJ IDEA and Android Studio.
Keep Java and Kotlin work in IntelliJ IDEA.
Are JetBrains AI features included in the IDE license?
No, AI sits outside the base license. WebStorm’s licensing FAQ puts JetBrains AI on a separate 7-day trial, and JetBrains’ July 2025 IntelliJ IDEA post says AI-assisted coding comes with the All Products Pack or an additional AI subscription.
When Should You Revisit Your IDE Choice?
Take a second look when the stack adds or drops a JVM service, when release notes move a feature into the free tier, and after a first annual purchase while the refund window is still open.
That order follows cost of error. A stack change undermines the premise of the whole decision, while a free-tier change only alters the price. The refund window matters least, since it just limits how long a wrong pick stays reversible.
The window is short. JetBrains refunds annual WebStorm subscriptions within 30 days of purchase and monthly ones within 7 days (WebStorm licensing FAQ).
Past that, an annual subscription to the wrong IDE runs its full term.
