Coder is an open-source, self-hosted Cloud Development Environment (CDE) platform that enables organizations to provision secure, ephemeral, and scalable development workspaces in their own infrastructure or cloud. It centralizes source code and tooling, provides instant onboarding, integrates with popular IDEs, and allows both developers and AI coding agents to work safely and efficiently. Coder supports infrastructure as code, advanced networking, and granular security controls, making it suitable for enterprise-scale software development and DevOps workflows.
