Makerkit.dev's answer

Indie Hackers and Companies who want to launch quickly, without compromising on quality.

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.

Makerkit.dev's answer

Makerkit uses Next.js 15 (App Router), Supabase, React.js, Typescript and Stripe.

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.

Makerkit.dev's answer

Makerkit stands out by offering a truly modular architecture built with Turborepo, where core features like auth, billing, and notifications live in their own packages for better maintainability.

While most starters lock you into specific patterns or providers, Makerkit gives you flexibility with a multi-account system supporting both B2B and B2C scenarios, provider-agnostic billing, and edge-ready deployment options.

Beyond the basics, it includes production-ready features like multi-factor auth, real-time notifications, and team permissions - all built with Supabase, TypeScript, React Query, and modern tooling to make development a genuine pleasure.

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.

Makerkit.dev's answer

While other starters give you basic auth and a dashboard, Makerkit provides a genuinely modular foundation with the real features SaaS products need - like multi-factor auth, team permissions, real-time notifications, and provider-agnostic billing, all organized in clean, maintainable packages using Turborepo.

You get a first-class developer experience with TypeScript, React Query, and modern tooling, plus the flexibility to support both B2B and B2C scenarios, different payment providers, and edge deployment options.

Best of all, Makerkit is actively maintained with regular updates and responsive support, so you're building on a foundation that grows with your needs rather than painting yourself into a corner.

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.

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.
