TanStack

What is TanStack?

TanStack is a collection of open-source, headless utilities designed for web developers building complex applications. The project provides type-safe tools that handle specialized workflows including data management, data visualization, charts, tables, and UI components. TanStack's approach centers on headless architecture, allowing developers to manage business logic independently from presentation layers. This separation enables greater flexibility in how data flows through applications and how interfaces are implemented. The libraries are built with TypeScript, providing type safety across different project types. The TanStack ecosystem includes several focused libraries addressing specific challenges in modern web development. Rather than offering pre-styled components, the tools provide the underlying logic and structure, letting developers maintain control over styling and customization. The project serves developers working on applications with demanding data requirements—those needing sophisticated table interactions, complex state management, or advanced visualization capabilities. It appeals to teams prioritizing control, maintainability, and integration with existing codebases over pre-built solutions. All TanStack projects are available on GitHub under the TanStack organization, allowing developers to review source code, contribute, and track development. The open-source model enables community-driven improvements and transparency in how the tools evolve.
