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

About Planby

React component library for building timeline and scheduling applications.

Mission

Planby exists to solve a common developer problem: building timeline-based interfaces is time-consuming and complex. We provide a production-ready, performant React component that handles the difficult parts—virtualization, timezone management, drag-and-drop interactions—so developers can focus on their application logic instead of reinventing scheduling UI.

What We Build

Under Custom license, not commercial. Includes timeline rendering, virtualization, timezone support, and basic customization. Available on npm and GitHub.

PRO Version

Extended features for commercial applications: drag & drop, resize, advanced grid modes, premium support, and priority bug fixes. Licensed per developer seat.

Team & Maintainers

Planby is maintained by Karol Kozer, a software engineer specializing in React component libraries and performance optimization. The project benefits from contributions by developers worldwide who use Planby in production applications.

Contributors handle bug reports, feature requests, and pull requests through GitHub. PRO customers receive direct support via email and private channels.
