SYNCDATE is a web application for live two-way Google Calendar synchronization. Connect multiple Google accounts, select which calendars to sync, choose direction (one-way or two-way), and SYNCDATE keeps events aligned automatically in the background.

Key Features

  • Multi-account sync โ€” Connect multiple Google accounts and sync events between any of their calendars
  • One-way or two-way โ€” Flexible direction per sync process, including one-source-to-many-targets
  • Privacy by default โ€” Synced events show as "busy" by default; detailed copying is opt-in
  • Clean exit โ€” Delete a sync and optionally remove all events it created. Reversible and traceable
  • Fast webhook-driven sync โ€” Events propagate within seconds via Google push notifications, with 15-minute polling fallback
  • Recurring events โ€” Full support for recurring event sync with recurrence rules
  • Sync health dashboard โ€” Status, freshness, latency, error summaries, and actionable fix steps at a glance
  • Run history โ€” Per-run stats: created, updated, deleted, skipped, errors

Pricing

  • Free โ€” 2 calendars, 2 accounts, forever free
  • Starter โ€” $1.99/mo (4 accounts, 12 calendars in sync)
  • Pro โ€” $8.99/mo (8 accounts, 30 calendars, priority sync)

Built for professionals juggling multiple Google calendars across work, personal, and side-project accounts.

Outlook support with cross-provider sync - coming soon.

SST features and specs

  • Ease of Use
    SST is designed to simplify the process of building serverless applications, providing developers with higher-level abstractions and tools that streamline development.
  • Integration with AWS
    SST is well-integrated with AWS services, allowing developers to leverage the full power of AWS infrastructure while maintaining a focus on serverless architecture.
  • Live Lambda Development
    SST supports live Lambda development, enabling developers to make real-time changes and see them reflected immediately without the need for lengthy deployment processes.
  • Infrastructure as Code
    With SST, developers can define their infrastructure programmatically, which promotes version control, scalability, and collaboration among team members.
  • Flexibility
    SST provides flexibility to developers, allowing them to use popular libraries and frameworks alongside serverless components, thus accommodating various use cases.

Possible disadvantages of SST

  • Learning Curve
    Developers unfamiliar with SST and its abstractions may face a learning curve in understanding how to effectively use the toolkit and take full advantage of its features.
  • AWS Lock-in
    As SST is tightly integrated with AWS services, it can lead to vendor lock-in, making it challenging for organizations to switch to other cloud providers in the future.
  • Complexity for Small Projects
    For smaller projects, the overhead introduced by SST's abstractions and tooling might be unnecessary, adding complexity without significant benefits.
  • Dependency on Community Support
    SST relies on community support for maintenance and feature development, which could pose a risk if the community's interest wanes or if support does not keep pace with AWS innovations.

Questions & Answers

As answered by people managing SST and SYNCDATE.

What makes your product unique?

SYNCDATE's answer:

SYNCDATE treats sync as silent infrastructure โ€” 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 โ€” competitors start at $4โ€“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 โ€” 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 โ€” 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.
