The premier specialized IDE for modern JavaScript and TypeScript. Following its 2025 transition to a free non-commercial license, it is now the top choice for hobbyists wanting pro-grade tools. The 2025.3 update introduces native Claude Agent integration, a high-performance service-powered TypeScript engine, and unified settings for Bun, Deno, and Node.js. It remains heavier than text editors but offers unmatched deep-code analysis and out-of-the-box refactoring.

The industry's leading Python IDE, now unified into a single product. The late 2025 version features native MCP (Model Context Protocol) support for connecting AI agents like Claude or Cursor directly to the IDE's internal index. It includes world-class support for Django, Flask, and FastAPI, alongside a powerful Data Science suite. While it is more resource-heavy than VS Code, its built-in Jupyter Notebook support is now free for all users in the unified edition.
