What Is AWS Cloud9?

Amazon's browser-based IDE providing a code editor and terminal.

Definition

Amazon's browser-based IDE providing a code editor and terminal.

AWS closed Cloud9 to new customers on 07-25-2024 and the service is in maintenance mode, but no end-of-life date has been announced and it is not on the AWS full-shutdown list. Existing users retain access; new projects should choose an actively developed CDE.
