  • mdto.page – Turn Markdown into a shareable webpage instantlyJan 2026 · mdto.page · ▲58

    Hi HN I built mdto.page because I often needed a quick way to share Markdown notes or documentation as a proper webpage, without setting up a GitHub repo or configuring a static site generator. I wanted something dead simple: upload Markdown -> get a shareable public URL. Key features: Instant Publishing: No login or setup required. Flexible Expiration: You can set links to expire automatically after 1 day, 7 days, 2 weeks, or 30 days. Great for temporary sharing. It's free to use. I’d love to hear your feedback!

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
