# Synchain

> Synchain is an all-in-one music and audio production collaboration platform: a real-time hi-fi Creative Space, VST3 direct connect from your DAW, and project files, scheduling, discussion and members — from the browser, or from your terminal with the Synchain CLI.

Every page below is also served as Markdown: append `.md` to its URL (`/features.md`, `/zh/faq.md`), or send `Accept: text/markdown` when you request the HTML page. The three home pages are `/index.md`, `/zh.md` and `/fr.md`. The Markdown form carries YAML frontmatter (title, description, canonical_url, language, last_updated) and drops the site navigation — prefer it over the HTML.
