Reliability

## Which Calendar API protects your application when calendar providers go down? 

Nylas' reliability depends on third-party calendar APIs like Google or Microsoft, and if those services are slow or go down, your users feel it.

Cronofy is different. Our Sync Engine caches availability internally across all connected calendars, which means stable scheduling for your users - even when external providers hit issues. It’s why we guarantee 99.99% uptime to every customer, on every plan.

Performance

## Which platform delivers faster scheduling experiences for your users, at scale?

Nylas’ v3 API introduced a domain-specific model, meaning availability queries are restricted to within an organisation. If you need to check calendars across different companies or domains - something that’s common across healthcare, recruitment, and education platforms - you’re stuck making multiple external API calls.

Cronofy’s approach has no such restrictions. You only need to make one API call across all domains, meaning faster performance, less load, and a noticeably better experience for your users.

> Cronofy provided exceptional support throughout our transition from Nylas. Their tech support is prompt, their documentation is thorough, and their assistance during the migration process was top-notch. As a result, our users are highly satisfied with the improvements we’ve been able to deliver since the migration.

— Brent Totty, Senior Product Manager, Kajabi

Stability

## Which Calendar API provider never breaks your integration?

Nylas has already deprecated two API versions, and v3 is now the standard. Every migration costs time, burns engineering resources, and risks breaking critical scheduling features - only to maintain the status quo.

When choosing a scheduling partner, stability isn’t optional, it’s critical. It frees up your time to invest in new capabilities instead of maintaining existing ones. Cronofy has supported our v1 API for over a decade, continuously enhancing it with backward-compatible improvements. Our users have never needed to plan for rework, rebuilds, or rushed updates.

Support

## Who supports your team - before, during and after the integration? 

Unlike Nylas, when you engage with Cronofy you won’t be stuck speaking to an SDR - you’ll get help from a dedicated technical advisor who support teams building products just like yours to plan, architect, and validate your integration.

When you’re building scheduling into your product, it’s the iceberg under the surface, like edge cases, calendar inconsistencies and availability logic that shift timelines and put your roadmap behind. With Cronofy, you’ll receive full support from Day 0 to help you map your integration, avoid costly missteps, and accelerate time to value.

Specialist

## Which solution was truly built for scheduling? 

Nylas started as an email API company, with scheduling later released as an add-on. Cronofy is different, and our expert engineering team lives and breathes scheduling so you don’t have to.

Cronofy has focused exclusively on scheduling since it was founded in 2014, providing the APIs, infrastructure, and UI components product teams need to build world-class scheduling experiences and get them in the hands of your users as quickly as possible.

Compliance

## Who is the better choice for regulated industries?

The nature of the data Cronofy handles on behalf of its customers requires security to be core to the approach to building, scaling and managing our service.

Built for compliance-first teams, Cronofy is GDPR, HIPAA, SOC 2 compliant, as well as being ISO 27001, 27701 & 27018 certified.

Unlike Nylas, Cronofy is based in the EU and offers 6 data centre locations. We are committed to helping our customers meet their users strict data requirements across regions.
