HBuilderX

HBuilderX is a lightweight desktop IDE released by DCloud that targets front‑end development with HTML5, JavaScript, CSS and Vue. It provides fast startup, code completion, syntax highlighting and built‑in support for the uni‑app (x) framework as well as 5+App projects, allowing developers to write and preview code for multiple platforms from a single environment.

The editor is available for Windows, macOS (Intel and ARM) and Linux, and can be downloaded for free. Its interface includes features such as IntelliSense, UI components, markdown preview and a set of tools aimed at “geek” productivity, all integrated without the need for external plugins. The stable release is positioned as a primary choice for front‑end engineers who work with the uni‑app ecosystem and related web technologies.
