Somnia v0.3.0

First public release of Somnia — a native macOS browser fused with an Obsidian-style notes vault. SwiftUI + WebKit, single ~2.6 MB binary, zero external dependencies.

Highlights

Browser

• Spaces — group tabs into color-coded workspaces
• Lazy tab loading + LRU tab sleeping (sleeping tabs release their web process)
• Reader Mode (⌘⇧R), find on page (⌘F), history, autocomplete, downloads manager
• Private tabs (⌘⇧N) and native tracker/ad blocking

Notes

• Plain-markdown vault with [[wiki-links]] and automatic backlinks
• Force-directed graph of your notes, mini-graph on the Home screen
• Connect an external Obsidian vault (read-only)

Install

Download Somnia-v0.3.0-macos.zip, unzip, and move Somnia.app to Applications.

⚠️ The build is ad-hoc signed, so on first launch macOS will warn about an unidentified developer: right-click the app → Open once. Or just build from source — ./build.sh needs only the Xcode Command Line Tools.

Requires macOS 14+.
