Quill
What it is
Quill is a free, API-driven rich text editor for developers. Its API exposes content, changes, and events using JSON, with methods for accessing or changing content by indexes and lengths. The document model can be extended with custom formats and embeds, including slide decks, interactive checklists, and 3D models. Built-in formats include text styles, links, headings, lists, alignment, code blocks, images, video, and formulas that require KaTeX. Official modules provide toolbar, clipboard, keyboard, history, and syntax functions. History supports configurable undo and redo behavior. Clipboard matchers handle copy, cut, and paste, but the documentation warns that unsafe HTML handling can cause cross-site scripting vulnerabilities. Quill offers Snow and Bubble themes, supports modern desktop, tablet, and phone browsers, and can be installed with npm or loaded from jsDelivr. Slab maintains it under a BSD license.
