.io vs .org

Open-source projects often debate between .org's nonprofit credibility and .io's tech-savvy image. The .org extension has decades of trust in the open-source community (e.g., apache.org), while .io signals modern developer culture.

Choose .org for established open-source foundations, educational institutions, and nonprofits. Choose .io for modern developer tools, APIs, and tech-first open-source projects.
