Question 1

Is Code IDE the same as VS Code?

Accepted Answer

It uses Monaco — the same editor engine that powers VS Code — but it's a separate, browser-only application. There are no extensions, no language servers, and no terminal; the focus is editing, formatting, and running JavaScript in a sandbox.

Question 2

Does the AI assistant need an API key?

Accepted Answer

No. The AI assistant runs Hermes-3 locally via WebLLM on WebGPU. Nothing leaves your browser. The assistant proposes file edits as a dry-run diff that you Apply or discard.

Question 3

Can I open a real folder on my computer?

Accepted Answer

Yes — the editor uses the File System Access API to read and write a folder on disk. Inside Heyming OS, the same UI saves to the virtual filesystem instead.

Question 4

Does git really work?

Accepted Answer

There is git integration scoped to the workspace; it surfaces diffs, dirty state, and basic operations against a project. It's not a full git client and does not push/pull from remotes.

Question 5

What languages and formats are supported?

Accepted Answer

Syntax highlighting works for JavaScript, TypeScript, JSON, Markdown, CSS, HTML, Python, Shell, YAML, C/C++, Java, Go, and Rust. Prettier formats JS, TS, JSON, CSS, HTML, and Markdown. The sandboxed runner only executes JavaScript.

Question 6

What is WebLLM?

Accepted Answer

WebLLM is the runtime that streams an LLM into the browser and runs it on WebGPU. Code IDE uses it to host the on-device AI assistant (Hermes-3-Llama-3.1-8B). The model is downloaded once into OPFS and reused offline.
