Scheduling features



Control and customization

Developer productivity

Cronofy doesn’t support round robin scheduling across calendars.

Cronofy has read-only contacts for connected calendars, leading to manual effort.

Cronofy’s lower rate limit at 500 requests per 60 seconds, increasing disruption.

Cronofy doesn’t have the ability to white label the authentication flow, disrupting a unified user experience.

Cronofy lacks calendar webhooks and requires more dev work to fetch detailed event changes.

Nylas vs. Cronofy


Nylas’ tiered, all-inclusive pricing model has no hidden costs or usage limits. Nylas Calendar API includes Scheduler, which is more affordable, and does not include overage fees for important features like receiving notifications when participants accept or decline an event.


Look out for hidden costs with Cronofy’s tiered pricing model, including usage limits for features like Smart Invites (attendees status changes) which may be costly long term. If you’re looking for an out-of-the-box scheduling widget, be aware that Cronofy’s Scheduler is a separate package from the Calendar API and more costly.


With Nylas, your users are connected to your own private Google project, giving you more control over data, privacy measures, and security. De-risk hitting quota limits and ensure a smooth scheduling experience. Learn the pros and cons of using a shared vs. private Google Cloud Project.


With Cronofy, users are authenticated on a shared Google project among other Cronofy customers. Your chances of hitting rate limits increase, which may stop you from completing any scheduling for your users. Shared tenants on a single project leads to less control over scopes, and a higher vulnerability from scope changes or missed verification deadlines controlled by Cronofy.


Nylas commits to a 99.9% SLA guaranteed uptime, including incidents from the Nylas platform as well as third-party incidents, becoming a single point of accountability.


Cronofy commits to a 99.99% uptime, but their SLA excludes any incidents caused by third-parties such as direct hosting subcontractors and equipment, software, cloud providers or technology of any third-party equipment.

Support & onboarding

Nylas’ global team offers support across all timezones to meet your customers’ SLAs. Choose from three support and onboarding tiers for quicker response times with options to access both email and phone options.


Cronofy has a smaller team based in the EU, offering support only on UK hours (8:30a-5:30p GMT). They do not have options to upgrade support or onboarding tiers. With email-only support, it can make it hard to access support in a timely manner.

Frequently asked questions

What is Cronofy?

Cronofy is a tool that allows developers to power calendar integrations for Apple, Google, Microsoft Exchange, Microsoft Office 365, and using a single API. Similar to Nylas, using a single API helps businesses save time and money with initial builds and on-going maintenance.

What is a connected account?

A connected account refers to an email address associated with an email, calendar, or contacts account that has been connected to the Nylas platform.

How does Nylas give developers more control and ownership compared to Cronofy?

Nylas is a more configurable API solution than Cronofy, enabling developers to easily own all aspects of their end user journey, such as owning end user authentication experiences or customizing end user workflows. Developers can choose to use what’s available out-of-the-box for a quicker solution, or choose to build their own custom features for a native experience. Examples include custom out-of-the box scheduling UI, integrations with 3rd party applications, and white labeled authentication workflows.

How does Nylas’ pricing differ from Cronofy’s?

Nylas’s scheduling solution includes the Calendar API, Scheduler, and Contacts API; they are not sold separately. Pricing is based on the tier and number of connected accounts per month; we do not limit usage rates or have overage charges by features. Volume discounts are also unlocked if you can commit to an annual contract agreement. 

Does Nylas offer something similar to the Cronofy Application Calendar?

Yes, the Nylas Virtual Calendar is a Nylas-hosted calendar and equivalent to the Cronofy Application Calendar. They can be used for scheduling objects or people without linking it to a person’s calendar.

Data privacy and security are top priorities. How secure is Nylas?

Nylas adheres to the most stringent security standards such as GDPR, CCPA, GLBA, and DPA. With security built into the core of our products, we also engage with respected 3rd party firms to audit our infrastructure and security practices, resulting in a SOC 2 Type II audit report, SOC 1 Type I audit report, HIPAA/HITRUST report, and ISO 27001 certification.
