# WebStorm 2026.3 Launches JetBrains Air for Agentic Development New IDE release integrates design, coding, and browser testing into one workflow. - **Source:** [The JetBrains Blog](https://brifing.si/source/782eebd1-7be8-49cc-b27c-e552516691b2) - **Published:** 2026-11-05 - **Topic:** [technology](https://brifing.si/c/technology) - **Original article:** - **On Brifing:** https://brifing.si/s/2d64921a-676c-4aec-9f1d-4cf18587796b ## Unified Agentic Workflow WebStorm 2026.3 introduces JetBrains Air, a dedicated layer for agentic development within the IDE. This feature allows developers to run multiple AI agents in parallel, track their progress, and verify outputs without leaving the coding environment. It centralizes the development process, enabling seamless interaction between human developers and various AI models. ## Figma Design Integration The new Figma Connect plugin eliminates manual copying of design tokens and CSS values. Developers can now inspect design layers directly within the IDE, providing AI agents with precise context. This integration streamlines the transition from design mockups to production code by removing the need to switch between Figma and WebStorm. ## Browser-Based AI Testing Chrome DevTools Connect allows AI agents to test their own code in a real browser environment. Agents can inspect the DOM, read console logs, and interact with page elements to reproduce runtime issues. This ensures that code is verified and functional before the developer even begins the final review process. ## Storybook Component Management Storybook Connect brings component documentation directly into the IDE, allowing developers to browse and search stories efficiently. The tool analyzes component props to identify missing stories and uses AI to generate them automatically. This keeps the development workflow synchronized with the Storybook app without requiring constant window switching. ## Flexible Agent Ecosystem JetBrains Air supports various ACP-compatible agents, including Claude Agent, GitHub Copilot, and Gemini. Users can leverage their existing subscriptions and API keys without needing a separate JetBrains AI plan. The system automatically detects installed agents, allowing developers to switch between different models mid-session to find the best fit for tasks. ## Accessibility and Sound Cues This release prioritizes accessibility by introducing sound cues for critical IDE events. Screen reader users receive audio feedback for build results, test completions, and breakpoint hits. These cues help developers monitor background processes across multiple monitors or projects without needing to constantly glance at the screen for status updates or error alerts. ## TypeScript 7 Performance Gains WebStorm 2026.3 includes stable support for TypeScript 7, which replaces the Node.js-based language service with a Go-based engine. This update significantly reduces overhead in large projects. For instance, testing on the Kibana codebase showed project load times dropping from twelve seconds to just three, enhancing overall IDE responsiveness for developers. ## Framework and Tooling Fixes The update addresses numerous issues across Angular, Sass, and CSS support. It resolves memory leaks in Angular that previously caused high CPU spikes and fixes template type inference for WSL users. Additionally, Vitest 5 and Mocha 12 integrations have been stabilized to ensure reliable testing workflows for modern JavaScript and TypeScript applications. ## Automated Error Reporting WebStorm now automatically sends technical error and UI freeze reports to JetBrains to help prioritize future fixes. The system is designed with privacy in mind, stripping personal details like usernames and file paths before transmission. Users maintain full control and can disable this data sharing feature within the system settings menu. ## Strategic Development Impact By integrating design, coding, and testing into a single interface, WebStorm 2026.3 shifts the focus toward end-to-end production efficiency. This release empowers developers to maintain context while utilizing AI agents for complex tasks. The combination of performance improvements and agentic workflows sets a new standard for modern, integrated software development environments. ## Sources covering this story - https://blog.jetbrains.com/webstorm/2026/11/webstorm-2026-3/ — --- _Summary written by Brifing from the original reporting.
