Which platforms are supported?

HBuilderX runs on Windows, macOS, and Linux. The download section of this page highlights platform-specific builds so you can choose the installer that matches your environment.

How does AI code completion work in HX?

AI code completion in HBuilderX works through a GitHub Copilot plugin workflow. After you install the Copilot plugin, configure the Node.js runtime, and sign in with GitHub, the editor shows inline suggestions as you type that you can accept, ignore, or refine with keyboard shortcuts.

Does AI completion work with Vue and uni-app?

Yes. AI suggestions are available while editing Vue single-file components and uni-app projects, complementing HBuilderX’s built-in Vue and uni-app tooling so you can work faster without leaving the editor.

Q: Can I use HBuilderX without AI features?

Yes. AI completion is optional and plugin-based. You can run HBuilderX as a fast, native IDE with its standard Vue, Markdown, and uni-app tooling and turn AI features on only if and when you need them.

Q: Is HBuilderX suitable for large projects?

HBuilderX is well-suited to larger projects because its native C++ architecture is designed to keep typing and navigation responsive, even when you work with big codebases and many open files.

// Markdown Power

Markdown That Feels Like Coding

Write better docs with split-screen preview, real-time sync, and a workflow built for technical writing and README maintenance.

# Release Notes
- Live preview & sync
- Smart paste for images/snippets
- Clean export-ready formatting

Markdown that feels like coding

HX treats Markdown as a first-class language with shortcuts, Emmet-like expansion, and preview tools, so writing docs feels as smooth as writing code.

Emmet-style Markdown snippets

Type short patterns and expand them into full Markdown structures—headings, lists, tables, and more—so common doc layouts take seconds instead of minutes.

Powerful shortcuts

Use keyboard shortcuts to quickly toggle bold, italics, code blocks, and checklists, or to move lines and sections without breaking your typing rhythm.

Live preview and sync

Split the editor to preview Markdown as you type, with synced scrolling that keeps your cursor and rendered document aligned.

Write docs like you write code

Multi-cursor editing, search and replace, and selection expansion all work inside Markdown, helping you refactor large docs and release notes with the same tools you use on source files.

Great for README and changelogs

Whether you’re updating a README, documenting APIs, or writing change logs, HX keeps formatting consistent and makes repetitive structures trivial to maintain.

Geek-friendly efficiency

Optimize for flow. HX is built for mouse-less coding: multi-cursor, smart selection, and fast hotkeys that keep your hands on the keyboard.

Mouse-less coding

Fast navigation, editing, and refactor loops.

Multi-cursor

Edit repeated patterns in seconds.

Smart selection

Expand semantic ranges without precision dragging.

Search & jump

Move through codebases with minimal friction.

AI inside HX: Copilot-powered coding, in-editor

HX supports AI code completion via the GitHub Copilot plugin workflow—inline suggestions, fast acceptance, and a smoother “stay-in-flow” editing loop, right where you type.

Inline completions that follow your context

AI completion

Get suggestions as you type in code and docs. Accept what you like, keep what you wrote, and iterate quickly—without breaking focus.

// accept suggestion → keep typing
// reject suggestion → continue your intent
// repeat → faster throughput, same control

Quick setup, native feel

Plugin

Enable the Copilot plugin inside HX and sign in when prompted, then start using AI suggestions in your normal editing workflow.
