Google I/O Extended is a series of local events that are organized by developer communities around the world as an extension of the main Google I/O conference. These events provide an opportunity for developers, enthusiasts, and tech communities to come together and experience Google I/O remotely.

Google I/O Extended events typically take place in various cities and countries and are hosted by local developer groups, technology organizations, or Google Developer Groups (GDGs). They are designed to provide a local gathering where attendees can watch the live stream or recorded sessions of the main Google I/O conference, participate in discussions, network with fellow developers, and engage in activities related to Google technologies.

While the main Google I/O conference takes place at Google's headquarters in California, not everyone can attend due to various constraints such as travel distance, costs, or limited availability of tickets. Google I/O Extended events aim to bridge this gap by bringing the Google I/O experience to different locations, allowing developers worldwide to connect and learn about the latest announcements and developments in Google's ecosystem.

Google I/O Extended events often include additional local content, such as guest speakers, workshops, hackathons, code labs, and community-led sessions, which complements the main conference content. These events foster collaboration, knowledge sharing, and community building among developers in their respective regions.

Attending a Google I/O Extended event provides developers with an opportunity to engage with like-minded individuals, gain insights from industry experts, and explore the latest technologies and trends showcased at Google I/O.
