Trix review
A focused, open-source editor for web apps that need attachments and structured content.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Trix is an open-source WYSIWYG rich text editor for web applications. It is aimed at developers adding writing areas for messages, comments, articles, lists, and other simple documents. Its structured internal document model separates editing from direct HTML manipulation, while the editor outputs consistent HTML. Trix is distributed by 37signals and is available as JavaScript packages in ESM and UMD formats, with custom elements such as <trix-editor> and <trix-toolbar>.
Its strongest fit is attachment-focused editing. Trix supports embedded file attachments, drag-and-drop and pasted file handling, image attachment previews, and embedded content attachments. It also offers unlimited undo and redo, customizable toolbar and formatting attributes, HTML sanitization with DOMPurify, and a programmatic editing API. Form integration through associated inputs helps connect the editor to web forms, while npm, ESM, UMD, and HTML forms provide practical integration paths for web projects. These capabilities make it a focused option when media handling and straightforward document editing matter more than a broad feature set.
Trix is free and open source, with self-hosted deployment rather than a hosted SaaS product. That model suits teams that want to embed the editor directly into their own web application and manage the surrounding experience themselves. The trade-off is a narrower scope: verified tables, collaboration, AI features, and broad framework support are not part of the documented positioning. Choose Trix for simple, attachment-aware writing experiences with structured content; consider another editor when collaborative editing, richer document features, or wider framework coverage are central requirements.
