Here's what that actually took. **[Mak Thevar](https://daily.dev/sources/o2vqkbcqq55qxk2hihh7u)** · [@makthevar](https://daily.dev/makthevar) · 1 min read · 11 upvotes · 0 comments ## Summary A developer shares the technical design behind Quiline, a browser-only markdown editor with no backend or account system. Read-only share links encode the entire document into the URL fragment so nothing is ever sent to a server, local images are saved as real files using the File System Access API instead of being uploaded, and a marketing/app split keeps the site crawlable despite having no server. The author invites discussion on how others have solved similar local-first architecture problems. ## Content Wrote up the real technical decisions behind Quiline, a free markdown editor with no account and no server. Covers the read-only share links that encode the whole document into the URL fragment (so nothing ever touches a backend), why local images get saved as real files via the File System Access API instead of uploaded anywhere, and the marketing/app split that keeps it crawlable without needing a server at all. Curious what this community thinks, especially if anyone's approached similar local-first problems differently **Try it:** Quiline is live and free, with no signup to get past: [quiline.app](http://quiline.app). ## Similar posts on daily.dev - [How we built a free video editor that never uploads your files](https://daily.dev/posts/how-we-built-a-free-video-editor-that-never-uploads-your-files-iog9cmrlm) · Medium · 17 upvotes · 1 comments - [Markdown with superpowers](https://daily.dev/posts/markdown-with-superpowers-fpvdvsip1) · Hacker News · 1 upvotes · 0 comments - [This open-source Markdown editor is replacing every other writing app I use](https://daily.dev/posts/this-open-source-markdown-editor-is-replacing-every-other-writing-app-i-use-uf5hr8r0f) · XDA Developers · 0 upvotes · 0 comments - [LocalMark Studio: A fast, local-first Markdown editor for real work.](https://daily.dev/posts/localmark-studio-a-fast-local-first-markdown-editor-for-real-work--wm2q88fn1) · Product Hunt · 93 upvotes · 6 comments --- Tags: [#webdev](https://daily.dev/tags/webdev), [#markdown](https://daily.dev/tags/markdown), [#local-first](https://daily.dev/tags/local-first) [View this post on daily.dev](https://daily.dev/posts/i-built-a-markdown-editor-with-zero-backend-here-s-what-that-actually-took--phppmwyko) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"DiscussionForumPosting","mainEntityOfPage":"https://daily.dev/posts/i-built-a-markdown-editor-with-zero-backend-here-s-what-that-actually-took--phppmwyko","headline":"I built a markdown editor with zero backend.
