Code Editors & IDEs · Updated 2026
Quick Verdict
Choose Zed if you prioritize raw speed and built-in, real-time collaboration. Choose Atom if you value deep customization, a vast extension ecosystem, and are comfortable with a project that is no longer actively developed.
Zed and Atom represent two distinct eras and philosophies in code editors. Zed is a modern, performance-first editor built in Rust, offering native speed and integrated multiplayer features. Atom, built on web technologies, pioneered the hackable editor concept with unparalleled extensibility via its vast package ecosystem. While Zed is free and actively developed, Atom is open source but its development was officially sunset in December 2022.
