The first link included has nothing to do with using Obsidian to publish a site? This whole comment feels like an automated ad.

According to the Obsidian roadmap real-time collaboration will be added soon as a core feature.

For anyone interested in making their Obsidian vault into a site there are multiple options:

1. Using the official Obsidian Publish.

2. Using Quartz (or Obsidian Digital Garden)

3. Astro (custom coded, or any other static site generator, e.g. Jekyll or Hugo.

4. Astro Starlight (or any other pre-built documentation tool that can use markdown or mdx)
