Products that do what Open-Source Notion UI, Lotion does
My friend and I love the Notion UI, so we open-source a version we have been building. - Block-based editor - Drag to reorder blocks - Basic Markdown-parsing including bold, italic, headings and divider - Type '/' for command menu and shortcuts Tiny fun detail: When you move between blocks with your arrow keys, your cursor will remain at roughly the same horizontal position (vs jumping to the start or end of a block). Lotion is quite limited for now, and we would love any contributions (e.g. image blocks, video blocks, code blocks, etc.)

Hello everyone! I'm a solo developer who's been doing UI/UX work since 2007. Over the years, I watched design tools evolve from lightweight products into bloated feature-heavy platforms. I kept finding myself using a small amount of the features while the rest just mostly got in the way. So a few years ago I set out to build a design tool just like I wanted. So I built Vecti with what I actually need: pixel-perfect grid snapping, a performant canvas renderer, shared asset libraries, and export/presentation features. No collaborative whiteboarding. No plugin ecosystem. No enterprise…

Hi HN! We at Moment[1] are working on Notion alternative which is (1) rich and collaborative, but (2) also just plain-old Markdown files, stored in git (ok, technically in jj), on local disk. We think the era of rigid SaaS UI is, basically, over: coding agents (`claude`, `amp`, `copilot`, `opencode`, etc.) are good enough now that they instantly build custom UI that fits your needs exactly. The very best agents in the world are coding agents, and we want to allow people to simply use them, e.g., to build little internal tools—but without compromising on collaboration. Moment aims to cover…
