Launch HN: Unlayer (YC W22) – Add email and document builders to your app

Unlayer, a Y Combinator company, is launching a broader product story on Hacker News. The startup lets other applications embed content creation tools—email builders, page designers, and document generators—without each company having to build the entire editor, rendering, export, and permissions infrastructure from scratch. What makes Unlayer different is that it supports three workflows: developers can create templates in code using React components, end users can visually design and edit content with drag-and-drop, and AI agents can generate structured content rather than raw HTML. The problem is real: nearly every app eventually needs content creation, but it quickly becomes complex—email rendering quirks in Outlook, responsive layouts, asset uploads, merge tags, versioning, and countless edge cases unrelated to the core product. Unlayer unifies these workflows on a single foundation. The Elements library is open source; Unlayer monetizes through a commercial hosted platform that adds builders, collaboration, storage, and production features.
