Earthly CI is introduced as an innovative CI/CD platform aimed at addressing common challenges faced by modern software teams, such as slow build times, misaligned incentives between users and vendors, maintenance difficulties, and the limitations of traditional CI systems with monorepos. Built on the open-source project Earthly, it offers a fast, repeatable, and user-friendly solution that leverages containers for isolation and automatically caches every step to improve build speed significantly, potentially achieving up to 20X improvements. Earthly CI's pricing model aligns with user productivity, as it profits based on the number of active users rather than compute time, and it is designed to work effectively with both monorepos and polyrepos by understanding code interdependencies and facilitating high parallelism. The platform is available gradually to new users to ensure stability, with the goal of fostering the next generation of software development.
