Synara

The developer-first event & invite API that fixes ICS issues

SubscriptionAPIEmails239 impressions#161 of its week

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.

Synara provides a developer-first API that replaces .ics files with a JSON-based calendar invite and sync service.

Synara FAQ

How does Synara handle updates across different calendar providers?+

A single PATCH call updates the event everywhere, and Synara normalises provider-specific rules to avoid duplicates or ignored updates.

Do I need to change my existing event model?+

No, you can keep your current model and send events to Synara, which converts them to the ACE format and handles delivery.

What happens to legacy .ics files?+

Synara provides automatic .ics fallback for clients that only understand the old format.

Is there a limit on webhook calls?+

All plans include event webhooks; higher tiers get priority webhook queueing.

Can I test Synara before committing?+

All plans include a 30-day free trial, and there is a free tier for testing and prototypes.
