Core JavaScript and TypeScript Features Become Free in IntelliJ IDEA | The IntelliJ IDEA Blog

IntelliJ IDEA is making core features for JavaScript, TypeScript, HTML, and CSS, previously exclusive to its Ultimate subscription, available for free in version 2026.1 to enhance modern Java development involving web technologies. This update includes essential React support, comprehensive syntax highlighting, reliable code completion, and advanced import management to improve efficiency and reduce errors in web application development. The platform also offers smooth code navigation, robust refactoring tools, and quality control features to maintain code integrity. Integrated workflows within the IDE now allow for streamlined project management, security monitoring, and consistency with tools like Prettier and ESLint. While these core features are free, advanced tools for full-stack development remain part of the Ultimate subscription, which can be accessed through a 30-day trial.
