DayPilot Alternatives: 8 Schedulers and Calendars Compared (2026)

DayPilot has sold scheduling components since the ASP.NET WebForms era, and its JavaScript family (Scheduler, Event Calendar, Monthly Calendar, Gantt, Kanban) is still the one many teams find first. The decision usually turns on two things: the gap between the free Lite edition and Pro is wide, with all-day events, resource columns and keyboard navigation all on the paid side; and the JavaScript edition has no built-in recurring events, which most teams discover after the first “every Tuesday” ticket.

This comparison covers DayPilot and seven alternatives, free and commercial, on the axes that drive the decision: what the free tier includes, recurrence, resource and timeline views, 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, feature matrices and pricing pages, read between August and October 2026. The one claim here about a competitor’s missing capability, DayPilot’s lack of recurrence in JavaScript, is both the vendor’s own documented statement and the result of a test we ran in DayPilot’s public Pro demo.

What DayPilot does well, and who should stay on it

Credit where due: DayPilot Pro is a mature, perpetual-license family whose feature list reaches well past a calendar. The Scheduler renders a horizontal timeline for multiple resources with resource trees, frozen rows and parent resources; the Gantt adds dependency links; Kanban is in the same license. Export is one call, exportAs(), to SVG, PNG, JPEG or Excel, with PDF and print alongside. Maintenance renews at 25% of the license price, and DayPilot is the only vendor here selling distinct Web, SaaS and OEM licenses, so a SaaS company pays for its model rather than negotiating an exception.

If you need scheduler plus Gantt plus Kanban in one perpetual license for a single application, and your recurring series are expanded on the server (as they are in DayPilot’s own ASP.NET and Java editions), DayPilot Pro is a sound choice and this page will not talk you out of it.

Look at alternatives when you are on Lite and keep hitting the Pro line (Lite has no all-day events, no resource columns, no year view, no touch support, no keyboard navigation, no export or print, and “partial” framework support); when your events repeat and you do not want to own a recurrence engine with its DST edge cases; when the $649 Web Mini (one app, one instance, one developer, no source code, six months of non-renewable support) is the tier you can afford but not the one you need; or when accessibility is a requirement, since DayPilot publishes no ARIA or WCAG statement.

The free and open-source alternatives

FullCalendar

FullCalendar is where most DayPilot Lite users should look first, because its free tier is simply larger. The MIT core (around 2.4 million weekly npm downloads) covers day, week, month, list and multi-month views, drag and drop, named IANA time zones, RTL, an iCalendar feed plugin, and a free rrule plugin for RFC 5545 recurrence with exdate. All-day events and a year view, both Pro in DayPilot, are free here. Premium, from $480 a year for up to ten developers, adds the Timeline views, the Vertical Resource view, resource data and print, with a 50% renewal discount. Caveats: the built-in recurrence (without the plugin) is “a limited featureset” in FullCalendar’s own words, there is no built-in event editor, no Gantt, no Excel export, and DST behavior is not documented.

Choose it over DayPilot if: you are on Lite and need all-day events, recurrence or time zones for free. Stay on DayPilot if: you need Gantt or Kanban, or a perpetual license with source code.

react-big-calendar

react-big-calendar is MIT, React only, at roughly 1.2 million weekly downloads. It gives away two things DayPilot charges for: resource columns in the day view and drag and drop (as an add-on). Like DayPilot JS it has no recurrence, and it adds 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 no accessibility documentation.

Choose it over DayPilot if: you need a free React calendar with resource columns and nothing recurs. Stay on DayPilot if: you need a timeline, or anything other than React.

Schedule-X

Schedule-X is the Temporal-based newcomer (about 174,000 weekly downloads), and its free tier is the inverse of DayPilot’s: 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). DayPilot Lite lets you drag; Schedule-X free does not. There is no horizontal timeline in any tier, no year view, and no documented accessibility or DST behavior.

Choose it over DayPilot if: you want free recurrence and iCal in a modern calendar and will pay a flat project fee for interaction. Stay on DayPilot 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. Calendar resource views are marked both “planned” and “Premium plan”, and the recurrence docs say “It does not support every rule or combination yet”. Against DayPilot it offers recurrence where DayPilot JS has none, as a per-developer subscription rather than a perpetual price.

Choose it over DayPilot if: you are a Material UI shop on React and want recurrence handled for you. Stay on DayPilot if: you need a perpetual license, Gantt, or any framework other than React.

The commercial alternatives

Syncfusion Scheduler

Syncfusion’s Scheduler, inside a catalog of 1,600+ components, matches DayPilot Pro feature for feature and then some: seven calendar views plus five timeline views, four resource grouping modes, RFC 5545 recurrence with a built-in editor, per-event time zones, iCal import and export, Excel export, print, Google and Outlook sync, and a WCAG 2.2 and Section 508 statement DayPilot does not publish. The Gantt is in the same suite. Paid pricing is quote-only 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 DayPilot if: you qualify for the Community license, or want the broadest feature set with a formal accessibility claim and can take a sales call. Stay on DayPilot if: you want a published perpetual price and a lighter dependency.

Bryntum Calendar

Bryntum Calendar is the top of the market, sold with a planning suite (Scheduler, Scheduler Pro, Gantt, Task Board, Grid) that overlaps DayPilot’s family in scope and sits well above it in price: $680 per developer with a three-license minimum ($2,040), perpetual with source code, an annual Support & Updates subscription, named licenses, and an OEM agreement for SaaS products redistributed for a fee. For that: 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 has. The timeline is a separate product (Bryntum Scheduler, from $680 per developer); dependencies live in Scheduler Pro (from $1,100) and Gantt (from $940). DST behavior is not documented.

Choose it over DayPilot if: you are building a planning product and the operational features pay for themselves. Stay on DayPilot if: DayPilot Pro already covers your Gantt and scheduler needs at a fraction of the entry price.

CoreUI Scheduler

Our own entry, so judge the claims against the live demo and docs. CoreUI Scheduler has no Lite and no Pro: six views in one edition (day, week, month, agenda, resource and timeline), all-day events, resource and event colors, keyboard navigation, remote loading through a dataSource, virtualization past twelve resource columns, and timeline bars not split at midnight. Recurrence is where the contrast with DayPilot JS is sharpest: 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), and 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, with no separate SaaS or OEM price.

Honest limits: there is no free tier at all, where DayPilot Lite exists. No Gantt, no Kanban, no dependencies, no resource trees or frozen rows, no export of any kind, no print, no year view, no RTL, no context menu, no undo/redo, seven bundled locales. First released in August 2026 and still on a 0.x release line, against DayPilot’s decade-plus. Keyboard creation of events works in time-grid views only, and there is no formal WCAG conformance statement yet.

Choose it over DayPilot if: your events repeat, you need resource and timeline views in more than one framework, and you want one perpetual price without a SaaS surcharge. Stay on DayPilot if: you need Gantt, Kanban, export or a free edition.

What three years actually costs

A concrete scenario: five developers, one SaaS application, resource views and recurring events 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: DayPilot’s perpetual pricing is fair for a single internal application, and the 25% maintenance renewal is among the cheapest here. The cost moves when the application is a SaaS (the price roughly doubles) or when you count the recurrence engine you write and maintain yourself. 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; that is the number to compare with a DayPilot Office tier or a Syncfusion quote.

Migrating away from DayPilot

• Your recurrence code is the migration. Because DayPilot JS takes pre-expanded occurrences, you own an expansion step somewhere. Moving to CoreUI Scheduler, Syncfusion, FullCalendar with rrule or MUI X Premium means replacing it with an RRULE string plus exception dates on the master event and deleting the expansion; moving to react-big-calendar means keeping it. DayPilot’s recurrent and recurrentMasterId event fields are pass-through flags, not a rule format, so inventory where occurrences are generated first.
• Resource definitions translate; resource trees may not. DayPilot Pro’s resource trees, frozen rows and parent resources have no equivalent in CoreUI Scheduler (flat resource list), react-big-calendar or Schedule-X; Syncfusion’s hierarchical grouping and FullCalendar Premium’s resource hierarchy are the closest matches.
• Export leaves the component. exportAs() has a direct equivalent only in Syncfusion (Excel, iCal, print) and Bryntum (Excel, ICS, print). With CoreUI, FullCalendar or MUI X, exports move to the backend.
• Callbacks map; UI does not. Move, resize and time-range-selection callbacks have counterparts in every scheduler here. Context menus and anything built on the separate DayPilot modal library are UI you will rebuild.
• Spike your busiest resource screen first, with a recurring series that has an exception, behind a flag.

Which one should you pick?

• You need scheduler plus Gantt plus Kanban in one perpetual license and expand series on the server → stay on DayPilot Pro.
• You are on Lite and need all-day events, recurrence or time zones for free → FullCalendar.
• You need a free React calendar with resource columns and nothing repeats → react-big-calendar.
• You want free recurrence and iCal and can pay per project for interaction → Schedule-X.
• You are a Material UI shop on React → MUI X Scheduler.
• You qualify for the Community license, or need export, sync and a formal accessibility claim from one suite → Syncfusion.
• You are building a planning platform with undo/redo, workload and Gantt → Bryntum.
• Your events repeat, you need resource and timeline views across JavaScript, React, Vue or Angular, and you want one perpetual price with no SaaS surcharge → CoreUI Scheduler ($217 /dev).

The quickest test: open your DayPilot integration and find the code that turns a repeating booking into occurrences. If it exists and you maintain it, that code is the price of staying; weigh it against the licenses above.
