Million.js is an open-source, lightweight optimizing compiler designed to enhance the performance of React applications. The company behind the project, Million Software, was founded in 2021 by Aiden Bai. Bai started developing Million.js around the age of 16, driven by his frustration with the slow performance of websites on devices that weren't high-end, like M1 MacBooks. His journey into web development began in the fifth grade when he learned to use iframes to bypass his school's block on gaming websites.
The core of Million.js is its unique "block" virtual DOM, which significantly speeds up rendering compared to React's standard virtual DOM. Instead of the traditional method of comparing the entire DOM tree to find changes (a process that can be slow in applications with many elements), Million.js statically analyzes the code to identify which parts are dynamic. This allows it to create a map and directly update only the specific DOM nodes that have changed, turning a potentially linear time operation into a constant time one. This approach can make React components up to 70% faster, reduces memory usage, and improves initial load times.
The business operates primarily in the developer tools market, targeting web developers and companies with data-intensive or complex user interfaces who want to improve their application's speed without migrating away from React. It integrates with existing React projects and frameworks like Next.js, Astro, and Gatsby. The technology is delivered as an open-source JavaScript library available on NPM. Million.js can be implemented automatically, where the compiler figures out which components to optimize, or manually for more granular control. While the core library is open-source, the company generates revenue by helping enterprises improve their application performance. In April 2025, the company announced it had secured $500K in pre-seed funding to further develop its tooling for web performance.
