What OverType is

OverType is a free web Markdown editor designed around a transparent textarea placed over rendered Markdown. It uses the browser's native text input behavior for undo and redo, text selection, and mobile keyboards. Markdown syntax stays visible during editing, while the rendered view provides a preview. The editor can be added to a page with one script tag, without npm, a build step, or configuration; the project also documents npm and CDN distribution. Developers can use it with React, Vue, or vanilla JavaScript, or add it as a native Web Component. An optional toolbar provides formatting actions for bold, italic, code, links, headings, lists, task lists, quotes, and view mode. Solar and Cave themes are included, with global theming, mobile responsive styles, and support for custom toolbar buttons. A standalone Markdown parser is available for server-side rendering, static site generation, and browser extensions. Links open with Cmd/Ctrl-click so ordinary clicks can place the cursor. File paste and drop can be configured, with upload handling passed to the host application's backend callbacks. OverType supports Chrome 62+, Firefox 78+, Safari 16+, and Chromium-based Edge, and its repository identifies the license as MIT.

Who it suits

OverType suits developers adding a small Markdown editor to a web app who want native browser editing behavior, mobile keyboard support, and simple integration.
