A scheduling library is used to add schedulers to applications. These schedulers are used to schedule tasks at desired times by users, either daily, weekly, biweekly, or yearly, and are especially useful because they make scheduling and rescheduling events/appointments easy. Scheduling interfaces are common in travel software, project management, and admin panel applications.
Building a scheduling interface from scratch is time-consuming and expensive, which is why using a scheduling library is advantageous. In addition, most libraries are easy to learn and use.
While it may be tempting to use the first scheduling library you come across, not all libraries are created equal. In this article, you'll look at several scheduling libraries and compare them based on their features and functionality, community support, cost/licensing, developer experience, and ease of use.
All scheduling libraries have different features that set them apart. When selecting a library for your use case, it's important to look at its features, community support, cost, and first-party support for paid options.
The Bryntum Scheduler library has extensive and easy-to-use documentation that promotes a positive developer experience. This documentation includes guides on integration, customization, migration, APIs, and more.
In addition, on its examples page, you can browse different use cases highlighting features like drag and drop, filtering, grouping, tree view, and dependency lines. More importantly, this example page includes demos for integration with different frontend frameworks and server integration with PHP.
Some of Bryntum Scheduler's most notable features include the following:
- Easy customization of the user interface
- Modern browser support for Chrome, Firefox, Safari, and Microsoft Edge
- Integration with any server technology (including PHP, Java, ASP.NET)

The Bryntum Scheduler uses end user and original equipment manufacturer (OEM) licenses, and the cost of using the library starts at $850 USD.
You can find more information about the pricing options available on their pricing page.
Bryntum Scheduler Pro's most unique feature is that it supports automatic scheduling and can be used in conjunction with the Bryntum Gantt chart. It's the ideal choice for applications that require more than just a nice visual representation, such as the integration of complex scheduling scenarios.

More information on additional features can be found on Bryntum's website.
The Bryntum Scheduler Pro library shares the same 8,000+ member community forum with the other Bryntum libraries. It's the most advanced scheduling library in this roundup, and you can collaborate with Bryntum's services team to add special features to your application.
As is the case with the Bryntum Scheduler, the Bryntum Scheduler Pro uses end user and OEM licenses. The cost of using the library starts at $1,300 USD, which includes the license, source code, free upgrades, npm access, and forum support.

It has a documentation page that provides a short guide on how to get started. The documentation has guides on initialization, integration, CSS customization, plugin packages, and more. It also includes guides on developing in React, Vue.js, and Angular.
In addition, its demonstration page showcases testable examples of its features.
There are two versions of the library: standard and premium. The standard library adds a calendar component to your application, whereas the premium library, also known as FullCalender Scheduler, is a collection of premium plugins, such as timeline view, vertical resource view, and print optimization. FullCalender has over 300 settings built as separate modules to reduce file size, making it very lightweight in comparison to the other libraries in this roundup.
FullCalendar offers the following features:
- Powerful, lightweight open source library
- TypeScript support
- Customizable toolbar, theme, and sizing
- Day grid view, date navigation, clicking, and selecting
Some of its premium features include a timeline view, vertical resource view, and printer-friendly rendering.
Possessing both premium and open source versions, FullCalendar will always have a free and open source core, thanks to over 10 years of being open source and over 120 contributors. Developers can get help, report bugs, request features, and contribute if they choose to do so.
The library also provides an extra API and example pages that show practical examples of implementing different features alongside the source code.
Unlike the other libraries included in this roundup, the TOAST UI Calendar is completely free and open source.
Some of the most notable TOAST UI Calendar features include the following:
- Easily customizable view types, including daily, weekly, and monthly views
- Mouse-drag to adjust a schedule
- Ability to change the first day of a week
- Ability to drag and resize a schedule
However, the TOAST UI Calendar is not the most advanced one available, and it doesn't support resource grouping, task filtering, data binding, server-side integration, or the ability to export your calendar into a file format.
The library is open source, with over 10,000 stars and 1,000 forks on the GitHub repository.
The library is free, open source, and licensed under MIT.
The library comes with over one hundred UI components, and because of this, it may not be the ideal library if you just want to utilize its scheduler. However, each component is well documented, and there are demos available for almost every feature.
The Kendo UI Scheduler supports data binding and can be bound to both local and remote data. Another distinguishing feature is its right-to-left (RTL) support, which means that the scheduler component can be tailored to users who read from right to left.

- Day, week, work week, month, agenda, and timeline views
- Multiple resources and resource grouping
- Templates for appointments
