It stores everything as plain Markdown files, ships with a graph view and MCP integration for AI assistants like Claude and Cursor, and is free and MIT-licensed \u2014 an obsidian alternative self hosted that runs in a browser from your own server instead of installing on every device.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-what-notediscovery-does\">What NoteDiscovery Does<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Markdown editor with live preview \u2014 write in plain Markdown and see the rendered result as you type.<\/li>\n\n\n\n<li>Graph view and backlinks \u2014 visualize how notes connect, in the style Obsidian popularized.<\/li>\n\n\n\n<li>Plugin system \u2014 extend the base app with community or custom plugins.<\/li>\n\n\n\n<li>LaTeX support \u2014 render math equations with MathJax.<\/li>\n\n\n\n<li>HTML export \u2014 export any note as a standalone HTML file, or print it.<\/li>\n\n\n\n<li>MCP integration \u2014 Claude, Cursor, and other MCP-compatible AI tools can search, create, and organize notes directly.<\/li>\n\n\n\n<li>Docker single-container deployment \u2014 the whole app runs from one container, no separate database service to manage.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-why-self-hosted-obsidian\">Why &#8216;Self-Hosted Obsidian&#8217;?<\/h2>\n\n\n\n<p>Obsidian itself is desktop-only \u2014 there&#8217;s no official server mode, and syncing notes across devices means either manual file syncing or paying for Obsidian Sync, which runs roughly $4\u20138 per month. NoteDiscovery takes a different approach: it runs in a browser, served from your own VPS, so there&#8217;s no per-device install and no recurring sync subscription. As an obsidian sync alternative, the tradeoff is architectural rather than financial \u2014 you get one shared, browser-accessible vault instead of Obsidian&#8217;s local-first, synced-copies model.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-who-is-notediscovery-for\">Who Is NoteDiscovery For?<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Developers who want a browser-based Markdown vault they can reach from any device without installing anything locally.<\/li>\n\n\n\n<li>Small teams looking for a lighter, self-hosted alternative to Notion or Confluence for informal shared notes.<\/li>\n\n\n\n<li>Obsidian users who like the wikilink-and-graph-view model but are tired of paying for Obsidian Sync.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-limitations-to-know\">Limitations to Know<\/h2>\n\n\n\n<p>NoteDiscovery is a genuinely early-stage project \u2014 it was shown on Hacker News as a solo developer&#8217;s side project, and the maintainer has been explicit that it doesn&#8217;t yet come close to Obsidian&#8217;s depth. It doesn&#8217;t have Obsidian&#8217;s decade-plus community plugin library, feature parity with Obsidian&#8217;s most advanced plugins is still a work in progress, and it&#8217;s maintained by a single developer rather than a funded team. None of that makes it unusable for a lightweight team vault, but it&#8217;s worth setting expectations before migrating a large, plugin-heavy Obsidian setup over.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-why-run-notediscovery-on-contabo\">Why Run NoteDiscovery on Contabo?<\/h2>\n\n\n\n<p>Because NoteDiscovery ships as a single Docker container with no separate database service, it needs very little RAM \u2014 a Contabo Cloud VPS 4 (8 GB RAM, \u20ac4.50\/month) is more than enough headroom for a personal or small-team vault. Since it&#8217;s browser-based, any device with a browser can reach it, and running it on a Contabo VPS keeps the notes on EU-based infrastructure rather than a US-based sync provider.<\/p>\n\n\n\n<div class=\"wp-block-uagb-advanced-heading uagb-block-b514713f\"><h2 class=\"uagb-heading-text\">FAQ: NoteDiscovery<\/h2><\/div>\n\n\n\n<div class=\"schema-faq wp-block-yoast-faq-block\"><div class=\"schema-faq-section\" id=\"faq-question-1783943078135\"><strong class=\"schema-faq-question\">Is NoteDiscovery free?<\/strong> <p class=\"schema-faq-answer\">Yes. NoteDiscovery is 100% free and MIT-licensed, with no subscription tier and no paid features held back. The only cost is whatever infrastructure you run it on.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1783943091811\"><strong class=\"schema-faq-question\">Does NoteDiscovery support plugins?<\/strong> <p class=\"schema-faq-answer\">Yes, it has its own plugin system for extending the base app, though \u2014 as an early-stage, solo-maintained project \u2014 the plugin ecosystem is far smaller than Obsidian&#8217;s long-established community library. Expect to build or adapt plugins yourself for anything beyond the core feature set for now.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1783943106946\"><strong class=\"schema-faq-question\">What is the best self-hosted alternative to Obsidian?<\/strong> <p class=\"schema-faq-answer\">NoteDiscovery is the closest match if what you want is Obsidian&#8217;s Markdown-and-graph-view model but running in a browser from your own server. It&#8217;s not a like-for-like replacement \u2014 it&#8217;s newer and has a smaller plugin ecosystem \u2014 but for teams that want shared, browser-accessible notes rather than per-device desktop installs, it&#8217;s a genuine obsidian alternative self hosted option worth trying.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1783943114971\"><strong class=\"schema-faq-question\">Can I replace Obsidian Sync with a self-hosted tool?<\/strong> <p class=\"schema-faq-answer\">If your goal is specifically to stop paying for Obsidian Sync while keeping Obsidian itself, self-hosted file-sync tools like Syncthing can replace the syncing layer without changing the app you use. If you&#8217;re open to switching apps entirely, NoteDiscovery removes the sync question altogether by being browser-based and server-hosted from the start \u2014 there&#8217;s nothing to sync because there&#8217;s only one copy of the vault, on your server.<\/p> <\/div> <\/div>\n","protected":false},"excerpt":{"rendered":"<p>In short.
