[Coder](https://coder.com) 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](https://coder.com/docs/install) for other methods and a complete tutorial.
Try Coder with the [install script](https://github.com/coder/coder/blob/main/install.sh) on Linux and macOS, or grab the latest binary or installer from [GitHub Releases](https://github.com/coder/coder/releases/) on Windows:
```shell
curl -L https://coder.com/install.sh | sh
```
Start the server and open [http://localhost:3000](http://localhost:3000) to create your initial user, create a Docker template, and provision your first workspace:
```shell
coder server
```
For a production deployment, add a PostgreSQL database (version 13 or later) and an external access URL, and see our [validated architectures](https://coder.com/docs/admin/infrastructure/validated-architectures) for sizing and infrastructure guidance:
```shell
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.
