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

Hi HN, We’re Adeel and Umair, co-founders of Unlayer ( https://unlayer.com/ ). We let you add content creation to your applications without having to build an entire editor, renderer, template, and export stack yourself. Unlayer lets you create emails, web pages, and documents inside your app, in three different ways: in code, visually, or with AI. Here’s a demo: https://www.youtube.com/watch?v=0HsDtNkdMpM . We started with an embeddable email editor because a lot of products eventually need one: CRMs, marketing tools, customer engagement platforms, marketplaces, internal tools, and vertical SaaS apps all run into this at some point. At first, it sounds like a small feature: "just" add a drag and drop editor. In practice, it turns into a big pain. You end up dealing with email rendering, Outlook quirks, responsive layouts, templates, merge tags, image uploads, exports, permissions, localization, versioning, and a long tail of edge cases that have nothing to do with your core product Over time, we saw the same problem beyond email. Apps also need landing pages, invoices, proposals, reports, contracts, and PDFs. Some of this content is best created visually by end users. Some of it is better generated in code by developers. Increasingly, some of it is also generated by AI agents. Many teams eventually need all three workflows. That is the direction we have been working toward with Unlayer. There are three parts we are showing today: (1) Unlayer Elements . This is our open-source React component library for creating emails, pages, and documents in code (repo: https://github.com/unlayer/elements , more at https://unlayer.com/elements ). Instead of hand-writing raw HTML templates, developers can compose content using React components, reuse sections like headers, footers, CTAs, invoice rows, and branded blocks, keep templates in Git, and render them into production output. One newer use case we are seeing is AI-assisted content creation. If an AI agent is asked to create
