What it does
Synara is a developer-first calendar invite and event-sync service that replaces messyics files with fast, reliable API-driven scheduling that's built for modern apps. ICS is 25+ years old and parsed differently across providers. Updates get ignored, duplicated, or partially applied. Synara uses ACE, a clean JSON event format, to normalise event data. A single API call handles invites, updates, sync, and ICS fallback, so your app gets predictable behaviour everywhere.

Talanoa▲341Hi 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…
