Self-Hosted Cloud Development Environments and AI 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

Quickstart

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:

`1`	`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:

`1`	`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:

`1`	`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.
