nomo

Project Overview

Nomo brings the WYSIWYG Markdown editing experience into the open-source camp, and the difference is local-first: files always stay on your disk, with no account and no cloud. Built with Tauri 2 + Svelte 5, it keeps the installer small and the interface light, rendering as you type with source and two-pane modes on tap. Beyond light and dark themes it supports custom color schemes and fonts, plus a pinnable Markdown mini window for quick notes while writing.

Writing returns to the words themselves, with Markdown rendered as you go.

Notes

• Chip coverage: the current macOS build targets Apple Silicon, check Releases notes for Intel machines
• First-launch prompt: the app is unsigned so SmartScreen / Gatekeeper will warn, stick to official Releases packages
• Source build: needs Node.js 22, pnpm 11.5.1, Rust/Cargo, plus VS2022 Build Tools on Windows
• Commercial licensing: AGPL-3.0-or-later, contact the maintainer for commercial use
