Opportunity shouldn't depend on hardware or bandwidth

For too long, access to programming resources has been limited by access to infrastructure. App Dev for All’s Code on the Go (CoGo™) is a free and open-source app development environment that can run on almost any Android phone (including legacy devices) with or without an Internet connection.

Android-native IDE

Code, debug, and build apps on almost any Android phone or tablet.

100% offline-capable

Internet access isn’t required to code, debug, or build your app. 

Free and open-source

We’re committed to keeping all our tools free and open-source. No subscriptions, no paywalls.

Extend with plugins

Customize your environment with the tools you need without additional bloat from tools you don’t.

We collaborate with NGOs, governments, educational organizations, and other partners to support effective localization, distribution, training, and educational materials.
