Coder is a self-hosted platform for running AI coding agents and cloud development environments on infrastructure you control. It works with any cloud, IDE, OS, Git provider, and IDP.

Coder WorkspacesCopy Anchor Link

Coder Workspaces are cloud development environments defined with Terraform, connected through a secure Wireguard tunnel, and automatically shut down when not in use. Agents and developers share the same workspace infrastructure.

• Defined in Terraform: Templates describe the infrastructure for each workspace, from EC2 VMs and Kubernetes Pods to Docker containers.
• Any architecture and OS: Support ARM and x86-64 across Windows, Linux, and macOS from a single deployment.
• Managed by admins: Platform teams create and maintain templates that enforce approved images, resource limits, and security policies.
• Accessed from any IDE: Connect through VS Code, JetBrains, Cursor, a web terminal, remote desktop, or SSH.
• Automatic shutdown: Idle workspaces stop automatically to reduce cloud spend, and restart in seconds when needed.

Coder AgentsCopy Anchor Link

Coder Agents is a native AI coding agent built into Coder. The agent loop runs in the Coder control plane on your infrastructure, not in the workspace and not in a vendor's cloud. Developers interact with agents through the web UI or the REST API for programmatic and CI-driven workflows.

• Self-hosted agent loop: The control plane handles planning, model calls, and tool dispatch. Workspaces have zero AI awareness.
• No API keys in workspaces: LLM credentials stay in the control plane.
• Any model: Anthropic, OpenAI, Google, Bedrock, or self-hosted endpoints. Switching is a configuration change.
• Governance and cost controls: Centralized model approval, per-user spend limits, and audit logging.
• Open source and inspectable: The full platform is available to audit and extend.

IDE supportCopy Anchor Link

You can use:

• Any Web IDE, such as

  • code-server
  • JetBrains Projector
  • Jupyter
  • And others

• Your existing remote development environment:

  • JetBrains Gateway
  • VS Code Remote
  • Emacs

• A file sync such as Mutagen
