Demo video here: https://share.extend.ai/kRmSGKRF When we started, we tried every file viewer and document component library we could find. Unfortunately, none of them had all the functionality (and polish) that we wanted, so we ended up building our own for https://extend.ai/. It was only ever meant to be internal, but enough customers kept asking for it that we decided to…

    An open-source, collaborative, WYSIWYG Markdown editor▲460

    Inspired by the design and UI/UX of apps like Notion, and utility of open-source apps like StackEdit, I decided to create a minimalistic, local-only WYSIWYG Markdown editor. Some features worth highlighting: - Monaco editor and Prettier integration for code snippets - Tables (apparently the holy grail of WYSIWYG editing) - Embeds (for CodePen, CodeSandbox and YouTube, most useful for HTML or JSON exports) - Accepts Markdown paste-in, and "exports"/generates HTML, Markdown and JSON outputs - Collaboration (with real-time awareness and initial commenting system, available only when…

    Shuffle▲260

With this CLI, you can: * Sync your visual components from Shuffle directly into Cursor projects * Automatically generate clean, editable code from your designs * Keep your design and dev workflows tightly integrated without copy-pasting or re-exporting We built this to reduce the friction between prototyping and production. If you're using Cursor as your IDE and…
