Synara is a developer-first calendar invite and event-sync service that replaces messy .ics 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.
