Questions & Answers

As answered by people managing Seismic Learning and SYNCDATE.

What makes your product unique?

SYNCDATE's answer:

SYNCDATE treats sync as silent infrastructure — it shows proof instead of making promises. Every sync run is logged with stats, every error comes with a deterministic fix step, and every sync can be cleanly reversed with optional event cleanup. Most calendar sync tools are black boxes. SYNCDATE exposes sync health, freshness, and latency so you can verify it's working in seconds, not just hope it is.

Why should a person choose your product over its competitors?

SYNCDATE's answer:

A generous free-forever tier (2 accounts, 2 calendars) covers the most common use case at zero cost — competitors start at $4–12/mo. Privacy is the default: synced events show as "busy" unless you opt in to detailed copying. And if you ever want to stop, the Clean Exit flow removes all SYNCDATE-created events from your calendars — no orphaned copies left behind.

How would you describe the primary audience of your product?

SYNCDATE's answer:

Professionals managing multiple Google calendars across work, personal, and side-project accounts.
Remote workers who need their personal calendar to block time on their work calendar.
Freelancers and consultants juggling 3+ client calendars who need availability to stay consistent without manual copying.

What's the story behind your product?

SYNCDATE's answer:

SYNCDATE was born from a real problem: juggling multiple Google accounts and constantly getting double-booked because calendars didn't talk to each other. Existing tools were either expensive for what they offered, opaque about what they were doing, or left orphaned events behind when you stopped using them. SYNCDATE was built to be the sync tool we wanted — minimal, transparent, and safe to turn off.

Which are the primary technologies used for building your product?

SYNCDATE's answer:

Next.js (App Router) with TypeScript, PostgreSQL via Drizzle ORM, Redis with BullMQ for background job processing, Google Calendar API with webhook push notifications, and Stripe for billing. Deployed on a Hetzner server behind Cloudflare with a standalone Node.js worker for sync execution. Observability stack uses Grafana, Loki, Prometheus with PagerDuty for alerts.
