Self-hosted development environments defined in Terraform, for platform teams that want cloud workspaces and coding agents on their own infrastructure.
Every developer laptop drifts away from production eventually. Coder answers that with self-hosted cloud development environments and AI coding agents: workspaces are declared once and provisioned on infrastructure the company controls, which turns onboarding from days into seconds.
Workspaces are defined in Terraform, so one can be an EC2 virtual machine, a Kubernetes pod or a Docker container while the templates stay the same for everyone. Connections travel through a secure Wireguard tunnel, and idle resources shut down automatically to hold the bill down.
Two halves of the platform matter to different readers.
- Templates: Terraform files describe the infrastructure behind every workspace, with a public registry of ready-made ones.
- Editor access: extensions for VS Code and JetBrains Toolbox open a workspace in one click, and dev containers build from a devcontainer.json.
- Coder Agents: a native coding agent whose loop executes in the control plane, running any model from Anthropic, OpenAI, Google, Bedrock or a self-hosted endpoint.
- Credential isolation: no model credentials sit inside workspaces, and every agent action carries the identity of the user behind it.
- AI Gateway: centralised authentication, auditing and cost tracking for AI tooling across the deployment.
An install script covers Linux and macOS, with binaries and installers for Windows, and running the server is enough to try it locally. Production deployments add PostgreSQL 13 or later and an external access URL, with validated architectures published for sizing.
