FullCalendar Alternatives: 8 Schedulers and Calendars Compared (2026)

FullCalendar is the default answer to “we need a calendar in the app”, and for a calendar it is usually the right one. The catch appears when the calendar has to become a scheduler: the timeline view, the resource views and printing live in the Premium add-on, licensed per year. The honest question is not “is FullCalendar good?” but “are we about to pay a subscription for the three features that turn it into a scheduler?”

This comparison covers FullCalendar and seven alternatives, free and commercial, on the axes that drive the decision: which views are free, how recurrence is handled, framework coverage, three-year licensing cost, and migration effort. CoreUI publishes this page and its own Scheduler appears below; we put it where it honestly belongs, not first.

How we compared. Published documentation and pricing pages, read between August and October 2026, on the same axes for every product. Claims about a competitor’s missing feature are either the vendor’s own words or the result of a test we ran in a public demo.

What FullCalendar does well, and who should stay on it

Credit where due: FullCalendar is the most widely used calendar component on the web (around 2.4 million weekly npm downloads of @fullcalendar/core in August 2026), and the MIT core is complete for calendar use: day, week, month, list and multi-month (year) views, drag and drop, named IANA time zones, RTL, an iCalendar feed plugin, and a free rrule plugin for RFC 5545 recurrence with exdate and exrule. The React connector is MIT; Vue and Angular connectors are in the free tier.

If you need a calendar, with your own data, your own editor dialog and no resource axis, FullCalendar Standard costs nothing and this page will not talk you out of it. Premium, from $480 a year for up to ten developers, adds the Timeline views, the Vertical Resource view, the resource data layer and printing; renewals are discounted 50% before expiry, and if you stop paying you keep the last version released before expiry.

Look at alternatives when you need resources (rooms, people, machines) and would be paying Premium for exactly that; when you want recurrence in the data model rather than a plugin (FullCalendar calls its built-in recurrence “a limited featureset”, and neither it nor the plugin ships an editor UI); when you want a bundled event editor; or when your team spans frameworks and wants one commercial license.

The free and open-source alternatives

react-big-calendar

react-big-calendar describes itself as “Inspired by Full Calendar” and is the zero-cost default for React (MIT, about 1.2 million weekly downloads). Two things FullCalendar charges for are free here: resource columns in the day view and the drag-and-drop add-on. The trade-offs: React only, no recurrence at all, no time zone handling of its own (a localizer such as Moment or date-fns is mandatory), no built-in editor, no timeline, no export, and an eleven-month gap between releases before activity resumed in 2026.

Choose it over FullCalendar if: you need free resource columns in React and nothing recurs. Stay on FullCalendar if: recurrence, time zones or a timeline are on the roadmap.

Schedule-X

Schedule-X is the youngest fast-growing player (about 174,000 weekly downloads), built on the Temporal API. Its free tier is the inverse of MUI X: recurrence, an iCalendar plugin and a time zone selector are MIT, while drag and drop, resize, the interactive event modal and both resource views are Premium (€479 a year or €999 lifetime, per project, SaaS counted as one project). In the free version you cannot move an event with the mouse. There is no horizontal timeline in any tier, no year view, and no documented accessibility or DST behavior.

Choose it over FullCalendar if: you want a Temporal-based calendar with free recurrence and can pay one project fee for interaction. Stay on FullCalendar if: you need a timeline or free drag and drop.

MUI X Scheduler

MUI X Scheduler is in beta (9.0.0-beta.10 in August 2026), React only. MIT covers week, day, month and agenda views, drag and drop, resizing and theming. Premium at $599 per developer per year covers recurring events, exception dates, DST-aware recurrence, lazy loading and the Event Timeline. Resource views are marked both “planned” and “Premium plan”, the recurrence docs state “It does not support every rule or combination yet”, and import and export are planned.

Choose it over FullCalendar if: you are a Material UI shop on React and can wait for resource views. Stay on FullCalendar if: you need resource views or full RRULE coverage today, or anything other than React.

The commercial alternatives

DayPilot

DayPilot sells five components (Scheduler, Event Calendar, Monthly Calendar, Gantt, Kanban) with a free Lite edition (Apache-2.0) and a perpetual Pro edition from $649. The paywall sits much higher than FullCalendar’s: Lite has no all-day events, no resource columns, no year view, no keyboard navigation and no export; the $649 Web Mini covers one application and one developer without source code, and Web Team at $1,449 is the realistic entry. The decisive fact: the JavaScript edition has no built-in recurring events. The docs say “No built-in support for recurring events. You need to pass the expanded event occurrences in the events list”, and we confirmed it in the public Pro demo (2026.3.6993): 504 configuration properties, none for recurrence.

Choose it over FullCalendar if: you want a perpetual Gantt-plus-scheduler family with distinct SaaS and OEM licenses. Stay on FullCalendar if: your events repeat.

Bryntum Calendar

Bryntum Calendar is the top of the market, part of a planning suite (Scheduler, Scheduler Pro, Gantt, Task Board, Grid). Commercial only: $680 per developer with a three-license minimum ($2,040), perpetual with source code, an annual Support & Updates subscription, named licenses reassignable once per six months, and an OEM agreement for SaaS products redistributed for a fee. In return: twelve view types, 45 locales with RTL, RFC 5545-based recurrence with a built-in editor, ICS and Excel export and print, plus undo/redo, copy/paste, travel time and workload rendering nobody else here has. The horizontal timeline is a separate product (Bryntum Scheduler, from $680 per developer). DST behavior is not documented.

Choose it over FullCalendar if: you are building a planning product on one data model. Stay on FullCalendar if: you need one calendar; the entry price and the SaaS clause decide it.

Syncfusion Scheduler

Syncfusion’s Scheduler is one line in a catalog of 1,600+ components and has the widest coverage in the category: seven calendar views plus five timeline views, four resource grouping modes, RFC 5545 recurrence, per-event time zones, iCal both ways, Excel export, print, Google and Outlook sync, and a WCAG 2.2 and Section 508 statement. Prices are no longer published (paid tiers are a quote on a minimum one-year subscription), and the free Community license requires all three thresholds at once: under $1M revenue, up to five developers, no more than ten employees.

Choose it over FullCalendar if: you qualify for the Community license or are standardizing on one suite. Stay on FullCalendar if: you need a calendar and a price you can click.

CoreUI Scheduler

Our own entry, so judge the claims against the live demo and docs. CoreUI Scheduler ships six views in one edition: day, week, month, agenda, resource and timeline. The two views FullCalendar charges for are included, with virtualization past twelve resource columns and timeline bars that are not split at midnight. Recurrence is the foundation rather than a plugin: raw RFC 5545 RRULE strings (“any rule the standard allows is valid in the data model”), exception dates, windowed expansion, three editing scopes (occurrence, this and following, whole series), and DST behavior documented down to the spring-forward gap on a Temporal-based time model. The built-in editor has repeat presets. Every drag operation in the time-grid views has a keyboard equivalent with live-region announcements, verified on the public week view. The bundle is around 62 KB gzipped. One $217 license covers the JavaScript, React, Vue and Angular editions, perpetual, with twelve months of updates and unlimited projects.

Honest limits: first released in August 2026 and at version 0.2.0 as of October 2026, still pre-1.0, so FullCalendar’s track record is a real difference. No iCal import or export, no print, no Excel or PDF export, no year view, no RTL, no Gantt, seven bundled locales, keyboard creation of events in time-grid views only, and no formal WCAG conformance statement yet.

Choose it over FullCalendar if: you need resource and timeline views with real recurrence across more than one framework, at a one-time price. Stay on FullCalendar if: you need the iCal feed, printing, a year view, or ecosystem maturity.

What three years actually costs

A concrete scenario: five developers, one application, resource views required. List prices as published between August and October 2026; subscriptions assume renewal at list unless a renewal discount is published.

• optional renewals |

The pattern: FullCalendar Premium is priced per team, not per developer, so for a small team wanting only the timeline it stays competitive. The gap opens with per-developer subscriptions (MUI X) and per-business-model licensing (DayPilot’s SaaS tiers, Bryntum’s OEM clause). If you are also buying a data grid, CoreUI ONE at $347 per developer bundles the Scheduler with the Data Grid, the PRO component libraries for all four frameworks, Icons PRO and the Boilerplate; compare that against a Bryntum or Syncfusion suite rather than against FullCalendar alone.

Migrating away from FullCalendar

• Event objects translate; the recurrence model may not. FullCalendar’s simple recurrence (daysOfWeek, startTime, startRecur) has no direct equivalent anywhere. If you used the rrule plugin, rrule and exdate map almost one-to-one to CoreUI Scheduler’s RRULE string and exdates, to Syncfusion’s RecurrenceRule, and with field mapping to Bryntum’s object model. Moving to react-big-calendar or DayPilot JS means writing the expansion yourself, DST included.
• Resources become a data concept. CoreUI, Bryntum, Syncfusion and DayPilot Pro have a first-class resource model; react-big-calendar uses accessor props; MUI X has the model but not yet the views.
• View names differ. timeGridWeek becomes week, resourceTimeGridDay becomes a resource view, and custom-view durations have no universal equivalent.
• Editors are yours or the vendor’s. FullCalendar has no built-in editor, so you own one; keep it where the target has none, or delete it for a bundled editor (CoreUI, Bryntum, Syncfusion).
• Spike one screen first, with your real recurring series and largest resource list, behind a flag.

Which one should you pick?

• You need a calendar, not a scheduler → stay on FullCalendar Standard.
• You need the timeline on a small team and nothing else → FullCalendar Premium is still fair at $480 a year.
• You need free resource columns in React and nothing recurs → react-big-calendar.
• You want a Temporal-based calendar with free recurrence, paid per project → Schedule-X.
• You are a Material UI shop on React and can wait for resource views → MUI X Scheduler.
• You need Gantt plus scheduler as a perpetual family with SaaS or OEM licensing → DayPilot Pro.
• You are building a planning platform → Bryntum.
• You qualify for the Community license, or want one suite vendor → Syncfusion.
• You need resource and timeline views with standards-based recurrence across JavaScript, React, Vue or Angular, on one perpetual license → CoreUI Scheduler ($217 /dev).

Most teams discover the decision when the first “book this room every Tuesday” ticket arrives. If your calendar needs resources and recurrence together, the free tiers thin out quickly, and the question becomes which paid model fits how you ship.
