A library for building standards-compliant Web Components and adaptive UI systems for modern web applications.
FAST is an adaptive interface system for building modern web experiences using native Web Components. It provides tools like `@microsoft/fast-element` for creating standards-compliant, reusable UI components and `@fluentui/web-components` for pre-built components based on Fluent design. It solves the challenge of building interoperable, high-performance web interfaces that work with any frontend framework.
Frontend developers and teams building reusable UI components, design systems, or modern web applications that need framework-agnostic, standards-based solutions.
Developers choose FAST for its strong commitment to web standards, seamless integration with any existing tech stack, and the ability to incrementally adopt Web Components without rewriting their entire application.

Built on W3C Web Component standards, ensuring long-term browser compatibility and future-proofing, as emphasized in the README.
Components integrate with any front-end framework or build system, enabling incremental adoption without rewriting existing code, a key feature highlighted.
Lightweight and memory-efficient, with the README noting components work across all major browsers for performant applications.
Provides pre-built Web Components based on Microsoft's Fluent design, speeding up UI development for those adopting this style.
The Web Components ecosystem is less mature than React or Vue, leading to fewer community resources, third-party tools, and slower adoption.
While framework-agnostic, deep integration with specific frameworks may require extra configuration, as hinted in the integration docs, and debugging Web Components can be challenging.
Reliance on Fluent UI components ties the design to Microsoft's system, which might not suit all branding needs without significant customization.
