What should I use for a product that needs calendar embeds?

If you need calendar embeds in a product, the best choice depends on what kind of calendar and how much control you need. Here are the usual options:

1) Google Calendar embed

Best if you just need a simple public calendar view.

• Easy to embed with an iframe
• Good for event listings or shared schedules
• Limited styling/customization
• Works best for public calendars

2) Microsoft Outlook / Office 365 calendar embed

Best if your users are in the Microsoft ecosystem.

• Useful for enterprise/internal tools
• Embedding support is more limited and often not as straightforward as Google Calendar
• Often better to integrate via APIs than direct embed

3) Cal.com

Best if you want a modern embeddable scheduling product.

• Great for booking flows and availability
• Easy embed widgets
• Good customization
• Better if you want users to schedule meetings rather than just view calendars

4) FullCalendar

Best if you’re building the calendar UI yourself.

• Very flexible
• Works well in custom web apps
• Not an embed service; it’s a frontend calendar library
• Good for displaying events from your own backend

5) Calendly

Best if you need scheduling embeds.

• Easy to embed
• Strong for appointment booking
• Not ideal for displaying a full calendar interface
• Great for sales/demo/meeting scheduling

Quick recommendation

• Viewing public events: Google Calendar embed
• Booking meetings: Calendly or Cal.com
• Building a custom product calendar: FullCalendar
• Enterprise Microsoft users: Outlook integration/API

If you want, I can recommend the best option for your exact use case if you tell me:

• whether this is for viewing or booking
• whether it needs to be public or private
• whether you want a widget/embed or a full custom calendar UI
