Show HN: Habitat – A Self-Hosted Social Platform for Local Communities

Hacker News - Sun, 03/01/2026 - 3:20pm

Habitat is a free open-source, self hosted social platform for local communities. It is aimed at fostering local community discussions and discovery of areas of interest. This is why it is built primarily around location. A Habitat instance centers on a specific area, and the local community can make generic posts about that area, or they can make posts about specific locations in that area.

For some background reading you can find out:

Show HN: Mrkd – A native macOS Markdown viewer with iTerm2/VSCode theme import

Hacker News - Sun, 03/01/2026 - 3:18pm

Using Opus 4.6 I built a markdown viewer for macOS that uses zero web technology. No Electron, no WebView — markdown is parsed with cmark-gfm and rendered directly to NSAttributedString via TextKit 2. The result is native text selection, native accessibility, and a ~1MB binary that launches pretty much instantly. It supports GFM tables, task lists, syntax-highlighted code blocks, and inline images. You get a built-in themes (Solarized, Dracula, GitHub, Monokai) plus the ability to import your own from iTerm2 or VS Code theme files.

The part I’m most pleased with is the Quick Look integration — select a .md file in Finder, hit Space, and you get a fully themed preview using whatever theme and fonts you’ve configured in the app. No setup required; the QL extension registers automatically on first launch. It also bundles variable fonts (Geist, Inter, JetBrains Mono, iA Writer Mono, and more) so typography looks good out of the box.

The whole thing is built in Swift with no dependencies beyond cmark-gfm and Highlightr.
