SvelteMark is a modern, open-source Markdown editor designed with a singular focus on privacy and speed. Built using the latest Svelte 5 framework, it runs entirely in your browser as a Progressive Web App (PWA).
Unlike other editors that require accounts or sync data to the cloud, SvelteMark operates on a 100% local-first architecture. Your notes are stored securely within your browser's IndexedDB. This means your data never leaves your device, zero network requests are made for your content, and you can write completely offline.
Featuring a GitHub-inspired dark theme, SvelteMark combines a powerful CodeMirror 6 editor with a live, scroll-synchronized preview. It supports GitHub Flavored Markdown (GFM), mathematical equations via KaTeX, and Mermaid diagrams, making it perfect for developers, students, and writers who value data sovereignty.
Key Highlights:
Zero Knowledge: No servers, no accounts, no tracking.
Offline Ready: Installable as a native PWA on desktop and mobile.
Data Portability: Full JSON import/export capabilities.
