Dillinger vs Zettlr

Dillinger is a free web-based Markdown editor with live preview, cloud sync, and no signup requirement. Its Monaco editor includes syntax highlighting, multiple cursors, find and replace, and autocompletion. A side-by-side preview renders Markdown as you type and keeps scrolling aligned with the editor. Documents can be imported by drag and drop and exported as Markdown, styled HTML, or PDF. Dillinger also imports and saves files through GitHub, Dropbox, Google Drive, OneDrive, and Bitbucket; GitHub support covers public and private repositories and lets users save edits back. After the initial load, the editor works offline and keeps drafts in local storage, although cloud sync requires connectivity. Other options include dark mode, fullscreen Zen mode, and Vim and Emacs keybindings. The site describes use by developers, technical writers, and AI builders writing READMEs, documentation, blog posts, and LLM prompts. Documents save automatically in the browser, and the features page says data is not stored on Dillinger’s servers. The Free plan is free, with no signup, paywall, or usage limits.

Zettlr is a writing workbench for projects that can run from early notes through journal submissions and book manuscripts. It began as a Markdown editor for academic researchers and is also used by students, journalists, authors, and others writing substantial amounts. The app works offline on Windows, macOS, and Linux, and files stay on the user's computer. It supports standard Markdown and exports to formats supported by Pandoc. Citation manager support includes Zotero, JabRef, and Juris-M, with more than 9,000 citation styles. Note features include IDs, wiki-style internal links, related files, navigation, and graph view. Pandoc-powered profiles can apply templates to papers or prepare presentations for Beamer, reveal.js, or PowerPoint. Zettlr also renders LaTeX equations and Mermaid charts and supports extensive settings and custom CSS. It is free and open source, with no payment required to download. The maker says app data is not collected and update checks can be disabled. Older releases are unsupported; nightly releases may contain many bugs.
