Self‑hosted cloud workspaces defined by Terraform, auto‑scaled securely
Deploy secure, Terraform‑defined cloud workspaces that run on EC2, Kubernetes, or Docker, auto‑shut idle resources, and integrate with VS Code and JetBrains for rapid developer onboarding.
Coder lets engineering teams turn any public or private cloud into a fleet of ready‑to‑code workspaces. By describing environments with Terraform, organizations can provision EC2 VMs, Kubernetes pods, Docker containers, or other resources in a reproducible, version‑controlled way.
Each workspace connects through a high‑speed Wireguard tunnel, providing a secure, low‑latency link to the developer’s IDE—whether VS Code, JetBrains, or any compatible editor. Coder automatically suspends idle resources, cutting cloud spend, and its quick‑start installer lets you spin up a full server locally with Docker in minutes. Production deployments require a PostgreSQL instance and an external access URL, after which the platform scales to support hundreds of concurrent developers while maintaining centralized administration and auditability.
When teams consider Coder, these hosted platforms usually appear on the same shortlist.
Looking for a hosted option? These are the services engineering teams benchmark against before choosing open source.
Rapid onboarding of new engineers
Create a workspace in seconds, reducing setup time from days to minutes.
Scaling compute for heavy CI builds
Provision high‑performance VMs on demand and shut them down when idle.
Cost control for idle development machines
Automatically suspend unused resources, lowering monthly cloud bills.
Isolated environments for contractors
Provide secure, temporary workspaces that can be revoked instantly.
It can provision EC2 instances, Kubernetes pods, Docker containers, and other resources via Terraform on any cloud that Terraform supports.
Coder monitors workspace activity and suspends resources after a configurable idle period, freeing cloud capacity and reducing costs.
A PostgreSQL instance version 13 or higher is needed for persistent state in production deployments.
Coder is released under AGPL‑3.0. Core functionality is free; premium features are offered under a commercial license.
