An exclusive new experience — React Native support is on its way to Planby!

How it works

Comparison

Planby vs FullCalendarTimeline

FullCalendar is the most popular JavaScript scheduler — but its resource timeline view requires a $1,099/year premium license and still has no React-native virtualization.

Planby is a high-performance React scheduler and timeline component built timeline-first, with virtualization for large datasets (10k+ events), React Native support, and a fraction of the price.

TL;DR — When to Choose Each

Choose Planby

You need a timeline/Gantt view as the primary interface
Your dataset has 500+ events or resources
You want a native React component (hooks, TypeScript)
You need React Native support for mobile apps
You care about bundle size and performance
You need custom event rendering with full JSX control
FullCalendar's $1,099 premium license is not justified

Consider FullCalendar

You need month/week/day calendar views as primary views
Your team already uses FullCalendar across many projects
You need built-in Google Calendar sync
Vue or Angular is your framework (not React)
Your dataset is small (<500 events) and timeline is secondary

The FullCalendar Premium Problem

FullCalendar's free version doesn't include timeline or resource views. For those, you need Premium.

Performance: Timeline with 1,000+ Resources

FullCalendar Resource Timeline

Renders all resource rows in the DOM at once
Each event is a fully mounted DOM node — always
Scrolling through 500 resources causes layout recalculation
No built-in windowing — performance degrades linearly
Reported 3–5 second render times with 5,000+ events
jQuery internals — layout driven by DOM manipulation

Planby Timeline

Only visible rows and events are in the DOM
Bidirectional windowing — vertical (rows) + horizontal (time)
Scroll triggers a tiny diff — ~40 swaps, not 5,000 re-renders
Performance is constant regardless of dataset size
10,000 events load at the same speed as 100
Pure React — no DOM manipulation, works with React DevTools

React Integration: Native vs Wrapper

FullCalendar was built as a jQuery library and wrapped for React. Planby was built as a React component from the ground up. This difference has practical consequences.

FullCalendar in React — pain points

Uses ref-based imperative API (scrollToTime, refetchEvents)
Event callbacks receive native DOM events, not React synth events
Custom rendering via string templates or contentInjector — not JSX
State management doesn't integrate with Redux/Zustand naturally
React.StrictMode causes double mount issues
Server-side rendering (Next.js) requires workarounds

Planby in React — native experience

Hooks-first API: useEpg returns all you need
Fully controlled component — your state, your rules
Custom event rendering is just a JSX component prop
Works with any state manager (Zustand, Redux, Jotai)
Full TypeScript — autocomplete everywhere
Next.js and Vite compatible out of the box

FULLCALENDAR — imperative, DOM-based

// FullCalendar custom event rendering
eventContent: function(arg) {
  // No JSX — you return HTML strings
  // or DOM nodes manually
  let italicEl = document.createElement('i')
  italicEl.innerHTML = arg.event.title
  let arrayOfDomNodes = [italicEl]
  return { domNodes: arrayOfDomNodes }
}

PLANBY — pure JSX, fully typed

// Planby custom event rendering
const MyEvent = ({ program }) => (
  <Box p={2} bg="teal.600" borderRadius="md">
    <Text fontWeight="bold">
      {program.title}
    </Text>
    <Text fontSize="xs">{program.since}</Text>
  </Box>
)

// Pass it as a prop
<Layout renderProgram={MyEvent} />

Migrating from FullCalendar to Planby

If you have a resource timeline in FullCalendar, migration to Planby typically takes 1–2 days for most projects.

Conceptual mapping

FullCalendar concept	Planby equivalent
resources	channels
events	epg (programs)
eventContent	renderProgram
resourceLabelContent	renderChannel
slotMinTime / slotMaxTime	startDate / endDate
eventDrop callback	onProgramDrop callback
scrollToTime()	onScrollToNow() / scrollRef

Migration steps

Replace @fullcalendar/* packages with @nessprim/planby
Map your resources array to channels (id, title, uuid)
Map your events array to epg (id, channelUuid, title, since, till)
Replace eventContent with a renderProgram React component
Replace resourceLabelContent with renderChannel
Configure startDate/endDate instead of slotMinTime/slotMaxTime
Remove all imperative calendarRef API calls — use hooks instead

FAQ

FullCalendar vs Planby — FAQ

Common questions when evaluating Planby as a FullCalendar alternative.

What's the fastest React scheduler component?

Planby is a high-performance React scheduler and timeline component optimized for speed and large datasets. It uses virtual view rendering (windowing) to keep only visible events in the DOM, delivering 60fps scroll performance with 10,000+ events. Unlike FullCalendar or React Big Calendar, Planby renders fewer than 50 DOM nodes regardless of dataset size — making it the fastest React scheduler component for resource-heavy timelines.

Does Planby handle large event datasets?

Yes — Planby uses custom virtual view rendering optimized for thousands of events. Both axes are virtualized simultaneously: horizontal (time) and vertical (resources/rows). Loading 10,000 events looks identical to loading 100 from the browser's perspective, because events outside the viewport are never mounted into the DOM. This makes Planby the right choice for production apps with real-time streams, dense shift schedules, or large resource timelines.

Is Planby only for EPG / TV guides?

No. Planby started as an EPG (Electronic Program Guide) library, but it is a general-purpose React timeline scheduler. The same component powers shift planning, resource booking, project timelines, Gantt charts, appointment systems, conference agendas, sports schedules, and more. In Planby, "channels" are your resources (employees, rooms, machines, teams) and "programs" are your events (shifts, bookings, tasks, appointments). EPG is one of many supported use cases.

How does Planby compare to FullCalendar?

Planby and FullCalendar solve different problems. FullCalendar is calendar-first — its resource timeline view requires a $1,099/year Premium license and has no built-in virtualization. Planby is timeline-first, built natively for React (hooks, TypeScript, JSX custom rendering), includes virtualization for 10k+ events at no extra cost, and has a one-time PRO license with no annual renewal. For resource timeline use cases, Planby significantly outperforms FullCalendar in performance, React integration, and total cost.

Does Planby support React Native?

Yes. Planby supports React Native for building timeline and scheduler interfaces on iOS and Android. The React Native version is currently in BETA with PRO features included for early adopters. It uses the same conceptual API as the web version (channels, programs, useEpg hook), making it straightforward for teams already using Planby on the web.

What React scheduler alternatives are there to FullCalendar?

The main React scheduler alternatives to FullCalendar are: Planby (timeline-first, virtualized, React Native support, one-time license), React Big Calendar (calendar-first, no virtualization, free), DevExtreme Scheduler (enterprise, expensive, complex API), and DHTMLX Scheduler (jQuery-based wrapper). Planby is the strongest alternative for resource timeline use cases — it is the only one with built-in virtual rendering and React Native support.

What use cases does Planby support?

Planby supports: employee shift scheduling, resource and room booking, project timelines and Gantt charts, appointment and booking systems, TV and radio EPG (Electronic Program Guide), conference and event agendas, sports and tournament planners, production and manufacturing schedules, and any other horizontal resource timeline interface. The core model is simple: rows (channels) and events (programs) on a time axis.

Does Planby support drag and drop?

Yes. Planby PRO includes drag and drop for moving events between resource rows and resizing events to change duration. Events can be dragged horizontally to change their time and vertically to reassign them to a different resource. The drag callbacks return the new position data so you can update your state or persist to an API.

How do I install and get started with Planby?

Install Planby with npm install @nessprim/planby or yarn add @nessprim/planby. The package includes TypeScript types. Import useEpg, Epg, and Layout from the package. Pass your channels array (resources/rows) and epg array (events) to useEpg along with a startDate. A basic working scheduler takes under 5 minutes to set up.

What is the difference between Planby free and PRO?

Planby free includes core timeline rendering, basic customization, and community support — suitable for open-source and personal projects. Planby PRO adds drag and drop event management, advanced timezone handling, PRO documentation and code examples, Planby Portal access, and priority support. PRO is a one-time purchase per developer seat with no annual renewal fees.

npm install @nessprim/planby

Comparing Other React Timeline Alternatives

Besides FullCalendar, developers often evaluate react-calendar-timeline (horizontal resource timeline, unmaintained, no virtualization), React Big Calendar (calendar-first, no virtualization, no timeline view), and vis-timeline (jQuery-era API, no native React integration). All three lack bidirectional virtualization and React Native support. Planby outperforms all of them on large datasets and is the only option with a native React Native build.
