Secure environments for developers and their agents

---

Coder is a self-hosted 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 not used. Coder Agents runs a native AI coding agent whose loop executes in the control plane on your infrastructure, with no API keys in workspaces.

• Define cloud development environments in Terraform
  • EC2 VMs, Kubernetes Pods, Docker Containers, etc.
• Automatically shutdown idle resources to save on costs
• Onboard developers in seconds instead of days
• Delegate coding work to AI agents on your infrastructure
  • Bring any model (Anthropic, OpenAI, Google, Bedrock, self-hosted)
  • No LLM credentials in workspaces, user identity on every action
  • Centralized model governance, cost tracking, and audit logging

Check out our install guides for other methods and a complete tutorial.

Try Coder with the install script on Linux and macOS, or grab the latest binary or installer from GitHub Releases on Windows:

curl -L https://coder.com/install.sh | sh

Start the server and open http://localhost:3000 to create your initial user, create a Docker template, and provision your first workspace:

coder server

For a production deployment, add a PostgreSQL database (version 13 or later) and an external access URL, and see our validated architectures for sizing and infrastructure guidance:

coder server --postgres-url <url> --access-url <url>

Without these flags, Coder uses a built-in database and sets up a *.try.coder.app access URL for evaluation. Use coder --help for the full list of flags and environment variables.
