Coder

Coder is a self-hosted, open-source platform for cloud development environments and AI coding agents. Workspaces are defined with Terraform, connected through a secure WireGuard® tunnel, and automatically shut down when idle to save costs. Coder Agents runs a native AI coding agent whose loop executes in the control plane on your infrastructure, with no API keys stored in workspaces.

• Terraform-defined workspaces — describe your dev environment infrastructure (EC2 VMs, Kubernetes Pods, Docker Containers, etc.) using standard Terraform templates
• Automatic idle shutdown — workspaces automatically stop when not in use, reducing cloud spend without manual intervention
• AI coding agents — delegate coding tasks to AI agents running on your own infrastructure; bring any model (Anthropic, OpenAI, Google, Bedrock, or self-hosted)
• Centralized model governance — manage LLM credentials centrally with cost tracking, audit logging, and user identity on every agent action
• Fast developer onboarding — onboard developers in seconds instead of days using standardized, reproducible workspace templates
• IDE integrations — connect VS Code, JetBrains Gateway, JetBrains Toolbox, and other editors directly to Coder workspaces with one click
• Dev Containers support — build development environments using devcontainer.json on Docker, Kubernetes, and OpenShift via the envbuilder integration
• Self-hosted VS Code marketplace — run a private extension marketplace for restricted or air-gapped networks
• GitHub Actions integration — set up the Coder CLI in GitHub workflows using the official action
• Community registry — access community-contributed templates and modules from the Coder Registry to extend your platform

To get started, install Coder using the install script (curl -L https://coder.com/install.sh | sh), run coder server, and navigate to http://localhost:3000 to create your first workspace. For production, connect a PostgreSQL instance (v13+) and configure an external access URL.
