FullCalendar vs Mobiscroll Event Calendar

FullCalendar and Mobiscroll Event Calendar both ship day, week, and month views with drag-and-drop and TypeScript support. If you're choosing between them, you're deciding whether free standard calendar editing is enough or whether your application needs resource scheduling and interaction features bundled into a per-project commercial license. The install workflow differs too: FullCalendar installs from the public npm registry, while Mobiscroll requires CLI authentication against a private registry.

Start with these questions:

• Does the application need a resource timeline view in the first release?
• Does the install pipeline support CLI authentication and a private npm registry?
• Does per-developer Premium pricing or per-project commercial pricing fit the team better?

This comparison uses these criteria:

• Installation and setup
• Licensing and cost
• Calendar views
• Resource scheduling
• Framework support
• TypeScript support
• AI support

FullCalendar

FullCalendar is a JavaScript calendar library with an MIT-licensed core. The standard plugin set covers DayGrid, TimeGrid, List, and Multi-Month views. Drag-and-drop and resize are free via the @fullcalendar/interaction plugin. Resource scheduling, which maps events to rows of people, rooms, or other resources, requires the Premium license.

The FullCalendar architecture is plugin-based: each view type and feature is a separate importable package. The core package does nothing without at least one view plugin.

Installing FullCalendar

The standard packages are available on the public npm registry under the MIT license:

npm install @fullcalendar/core@6.1.20 @fullcalendar/daygrid@6.1.20 @fullcalendar/timegrid@6.1.20 @fullcalendar/list@6.1.20 @fullcalendar/interaction@6.1.20

The following shows a team calendar week view with events spanning April 27 to May 1:

<!-- index.html -->
<style>
  html, body { margin: 0; padding: 0; height: 100%; font-family: Arial, sans-serif; }
  #app { padding: 16px; height: 100vh; box-sizing: border-box; }
  #calendar { height: calc(100vh - 32px); }
</style>
<div id="app">
  <div id="calendar"></div>
</div>

import { Calendar } from '@fullcalendar/core';
import dayGridPlugin    from '@fullcalendar/daygrid';
import timeGridPlugin   from '@fullcalendar/timegrid';
import listPlugin       from '@fullcalendar/list';
import interactionPlugin from '@fullcalendar/interaction';

const calendarEl = document.getElementById('calendar');

const calendar = new Calendar(calendarEl, {
  plugins : [dayGridPlugin, timeGridPlugin, listPlugin, interactionPlugin],

  initialView  : 'timeGridWeek',
  initialDate  : '2026-04-28',
  height       : '100%',

  headerToolbar : {
    left   : 'prev,next today',
    center : 'title',
    right  : 'dayGridMonth,timeGridWeek,timeGridDay,listWeek'
  },

  slotMinTime : '08:00:00',
  slotMaxTime : '20:00:00',
  editable    : true,

  events : [
    { id : '1', title : 'Team Standup',    start : '2026-04-27T09:00', end : '2026-04-27T09:30' },
    { id : '2', title : 'Sprint Planning', start : '2026-04-27T10:00', end : '2026-04-27T12:00' },
    { id : '3', title : 'Design Review',   start : '2026-04-27T14:00', end : '2026-04-27T15:00' },
    { id : '4', title : 'API Workshop',    start : '2026-04-28T11:00', end : '2026-04-28T13:00' },
    { id : '5', title : 'Client Demo Prep', start : '2026-04-28T15:00', end : '2026-04-28T17:00' }
  ]
});

calendar.render();

Three setup details require attention:

• Drag-and-drop and event resize require the @fullcalendar/interaction plugin in the plugins array. Setting editable: true alone is insufficient without it.
• In v6, CSS is injected automatically by the JavaScript bundle. No manual CSS imports are needed.
• Resource views (@fullcalendar/resource-timeline, @fullcalendar/resource-timegrid) require a Premium license key set in schedulerLicenseKey.

FullCalendar is best when free standard calendar editing is enough

The MIT-licensed standard tier carries no evaluation watermark, no per-developer fee, and no restriction on open-source use. Day, week, month, list, and multi-month views are included, along with drag-and-drop, event resize, ICS import, and recurring events via the rrule plugin.

The public npm registry install requires no CLI setup or private registry configuration, which simplifies onboarding and CI/CD. Framework wrappers for React, Angular, and Vue are first-party and free. TypeScript definitions ship with every package, with no separate @types/ package required.

FullCalendar gives teams a production calendar with drag-and-drop at no cost, while Mobiscroll requires a paid project license after its trial. For teams where resource scheduling is a future requirement rather than a day-one need, FullCalendar is the lower-risk starting point.

FullCalendar tradeoffs

Resource scheduling requires the Premium subscription at $480 per developer per year. A three-person team pays $1,440 per year for resource views. The per-developer pricing scales unfavorably for large teams compared with the Mobiscroll per-project model.

Event dependencies, undo/redo, Excel export, and ICS export are absent. The subscription covers updates while active. The last released version remains usable after expiration without further updates.

FullCalendar ships no MCP server, no Claude Code skill, and no AI tooling.

FullCalendar is less attractive when resource scheduling is a day-one requirement, because the Premium subscription cost per developer reaches Mobiscroll's $995 per-project price at three developers in the first year.

FullCalendar cost

The MIT-licensed core is free with no per-developer fee. Premium, which includes resource timeline and resource time-grid views, starts at $480 per developer per year (for up to ten developers). OEM licensing for products shipped to multiple clients requires a custom quote.

FullCalendar developer experience

TypeScript definitions are bundled with every @fullcalendar/* package. The config object passed to new Calendar() covers all settings.

Drag-and-drop and event resize require @fullcalendar/interaction in the plugins array. Without it, events are read-only regardless of the editable property value.

Framework integrations ship as separate packages: @fullcalendar/react, @fullcalendar/angular, and @fullcalendar/vue3. Accessing the calendar API imperatively in React requires useRef and .getApi().

FullCalendar AI support

FullCalendar ships no MCP server, no Claude Code skill, and no built-in AI assistant.

The plugin system is the main friction point for AI agents. An agent without current documentation may omit @fullcalendar/interaction from the plugins array, producing a calendar where editable: true has no effect. Agents may also attempt to access resource views without a Premium license key, producing a watermark warning in the rendered output.

Use FullCalendar when resource scheduling can wait

FullCalendar fits applications that need standard calendar views with free drag-and-drop, installs from the public npm registry without authentication, and a later path to Premium resource scheduling. Teams that plan to add resource scheduling need to account for the $480-per-developer-per-year Premium cost upfront.

Mobiscroll Event Calendar

Mobiscroll Event Calendar is a commercial JavaScript calendar component that includes a resource timeline view. It ships four configurable view types (calendar, scheduler, timeline, and agenda) with drag-and-drop, resize, and drag-to-create included. Resources carry a color property that applies automatically to their events.

The Event Calendar is not available on the public npm registry. It requires authentication via the Mobiscroll CLI before any npm install command succeeds.

Installing Mobiscroll Event Calendar

Two commands set up Mobiscroll access: the global CLI install and a per-project config step.

npm install -g @mobiscroll/cli
mobiscroll config javascript

The mobiscroll config javascript command opens a browser to authenticate with Mobiscroll and configures npm to use the Mobiscroll private registry. The CLI prompts complete the package installation. A trial account is sufficient for evaluation.

The following shows a resource timeline for four team members across April 2026:

<!-- index.html -->
<style>
  html, body { margin: 0; padding: 0; height: 100%; font-family: Arial, sans-serif; }
  #app { padding: 16px; height: 100vh; box-sizing: border-box; }
  #calendar { height: calc(100vh - 32px); }
</style>
<div id="app">
  <div id="calendar"></div>
</div>

import * as mobiscroll from '@mobiscroll/javascript';
import '@mobiscroll/javascript/dist/css/mobiscroll.min.css';

mobiscroll.setOptions({ theme: 'material', themeVariant: 'light' });

mobiscroll.eventcalendar('#calendar', {
  view : {
    timeline : { type : 'month' }
  },
  selectedDate : new Date(2026, 3, 1).getTime(),
  dragToCreate : true,
  dragToMove   : true,
  dragToResize : true,
  resources : [
    { id : 1, name : 'Alice (Frontend)', color : '#4f46e5' },
    { id : 2, name : 'Bob (Backend)',    color : '#0ea5e9' },
    { id : 3, name : 'Carol (Design)',   color : '#10b981' },
    { id : 4, name : 'Dave (QA)',        color : '#f59e0b' }
  ],
  data : [
    { id : '1', resource : 1, title : 'UI Component Library', start : new Date(2026, 3, 6),  end : new Date(2026, 3, 11) },
    { id : '2', resource : 2, title : 'REST API Development', start : new Date(2026, 3, 6),  end : new Date(2026, 3, 11) },
    { id : '3', resource : 3, title : 'Wireframes v2',        start : new Date(2026, 3, 6),  end : new Date(2026, 3, 9)  },
    { id : '4', resource : 4, title : 'Regression Suite',     start : new Date(2026, 3, 6),  end : new Date(2026, 3, 8)  }
  ]
});

Four setup details require attention:

• The selectedDate property uses a timestamp. Calling .getTime() avoids string parsing and timezone ambiguity.
• Events use the data property, not events.
• The resource field on each event is resource, not resourceId.
• Calling mobiscroll.setOptions() before any component mount applies the theme globally.

Mobiscroll is best when resource scheduling is a day-one requirement

The timeline view, drag-and-drop, drag-to-create, and resize ship in the same package as the time-grid scheduler, calendar, and agenda views. Switching between view types requires only a view config change. Resource scheduling does not require a separate purchase or upgrade.

The view.timeline.type property accepts 'day', 'week', 'month', or 'year', so teams can cover daily planning, weekly rosters, monthly roadmaps, and annual capacity views without plugins.

Mobiscroll is the better choice when resource scheduling is a day-one requirement, while FullCalendar is cheaper for standard calendar views. The $995 per-project price includes the full scheduling package, while FullCalendar Premium costs $480 per developer per year for resource views.

Mobiscroll Event Calendar tradeoffs

The install process requires CLI authentication with the Mobiscroll private registry. Every developer and CI/CD environment must complete the authentication step before npm install works. This adds friction at onboarding and in automated pipelines.

Event dependencies are not supported. The library has no undo/redo stack. Excel export is absent. The print add-on is available at higher tiers only. ICS import is not supported.

Mobiscroll has no free tier for production use, while FullCalendar's standard calendar core is MIT licensed. Teams that want to evaluate Mobiscroll before purchase have a 90-day trial window.

Mobiscroll Event Calendar cost

Mobiscroll uses a per-project perpetual licensing model for internal applications:

• Scheduling & Calendaring: $995 (includes Event Calendar, single internal project)
• Complete: $1,955 (includes source code and priority support)
• Complete Company: $8,955 (multiple internal projects within one organization)

SaaS and multi-customer product licensing uses a subscription model with custom pricing based on customer count. Mobiscroll offers a 90-day trial and a 30-day money-back guarantee on purchases.

Mobiscroll Event Calendar developer experience

TypeScript definitions ship with the package. Documentation at mobiscroll.com covers all four view types with live examples.

Events use the data property (not events), and each event's resource field is resource, not resourceId. These naming differences are easy to miss when migrating from another library. Theme switching uses mobiscroll.setOptions({ themeVariant: 'dark' }), which applies globally without managing <link> tags.

Mobiscroll Event Calendar AI support

Mobiscroll ships no MCP server, no Claude Code skill, and no built-in AI assistant.

The private registry install process is the main friction point for AI agents. An agent following the standard npm install pattern generates npm install @mobiscroll/javascript, which fails without authentication. The data and resource property names also diverge from the conventions used by FullCalendar.

Use Mobiscroll when per-project pricing fits resource scheduling

Mobiscroll Event Calendar fits applications that need resource scheduling, drag-and-drop, and resize in a single $995 purchase, the team can accommodate CLI authentication across all development environments and CI/CD pipelines, and per-project pricing is preferable to per-developer pricing.

Which one to pick

FullCalendar is the right choice when the application starts with standard calendar views, installs must work from the public npm registry, and resource scheduling can be deferred or added via the Premium subscription. The MIT core includes drag-and-drop and event resize at no cost.

Mobiscroll Event Calendar is the better fit when resource scheduling is a day-one requirement and per-project pricing fits the budget better than per-developer Premium pricing. For teams with three or more developers who need resource views, the Mobiscroll per-project price undercuts FullCalendar Premium. The private registry install is the main operational constraint to evaluate.

Neither library ships AI tooling. Teams using AI coding agents should plan to provide current documentation in both cases, particularly for the plugin array requirement in FullCalendar and the data/resource property naming in Mobiscroll.

Bryntum Calendar

Bryntum Calendar is the stronger commercial choice when your application needs resource scheduling without Mobiscroll CLI authentication or FullCalendar Premium resource plugins. It supports React, Angular, Vue, and plain JavaScript, and Bryntum publishes per-developer pricing.

Bryntum also provides a free Calendar trial download. Trial packages and framework wrappers are available on the public npm registry, and the Bryntum Calendar npm repository guide explains licensed package access.
