Open-source, infinite calendars, and cheaper pricing.
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.
Calensync's answer
Pricing not based on number of accounts / calendars, as well as simply cheaper.
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.

Freelancers, entrepreneurs that deal with multiple businesses and accounts, or anyone who has multiple google calendars.
Makerkit.dev's answer:
Indie Hackers and Companies who want to launch quickly, without compromising on quality.
Calensync's answer
The story starts from frustration. I have multiple professional google calendars, as well as my personal one. On the professional ones, people can book events directly and, unfortunately, I had multiple conflicts. This lead me to first check for existing solutions and after being dissatisfied, deciding to create it myself.
No more conflicts between events since Calensync!
