Planby is a virtualized scheduler and timeline component optimized for React and React Native. It uses custom virtual view rendering (windowing) to keep only visible events in the DOM — delivering 60fps scroll performance even with 10,000+ events loaded. 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.

Yes — Planby uses custom virtual view rendering optimized for thousands of events. Both axes are virtualized simultaneously: horizontal (time axis) 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 in the DOM. This makes Planby the right choice for production apps with real-time data streams, large shift schedules, or dense resource timelines.

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.

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.

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.

Planby is a high-performance React scheduler and timeline component with virtualization for large datasets (10k+ events). It offers drag & drop, timezone support, pixel-precise event positioning, and custom JSX rendering — built specifically for React and React Native from the ground up, not wrapped from a jQuery library.

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), and DHTMLX Scheduler (jQuery-based). Planby is the strongest alternative for resource timeline use cases — it is the only one with built-in virtual rendering and React Native support.
