hls.js vs Gatsby

hls.js is an open‑source JavaScript library that enables HTML5 video elements to play HTTP Live Streaming (HLS) streams directly in browsers that support Media Source Extensions (MSE). It parses MPEG‑TS segments, handles adaptive bitrate switching, and provides a seamless playback experience without native HLS support. The library is lightweight, works in all modern browsers, and can be integrated with existing video players such as Video.js or custom UI components. It also offers extensive configuration options for low‑latency, live, and on‑demand streaming scenarios.

Gatsby is an open‑source framework that lets developers build blazing‑fast websites and apps using React, GraphQL, and modern web technologies. It compiles source files into static assets that can be deployed to any web host, delivering optimal performance and SEO out of the box. With a rich plugin ecosystem and seamless integration with headless CMSs and CI/CD platforms, Gatsby empowers agencies and developers to create scalable, secure, and highly maintainable web experiences while keeping the development workflow familiar and efficient.
