Deep Dive: Switching from CodeSandbox to Coder
Trade-offs, installation & data architecture
What you trade away
Coder is an infrastructure platform for durable workspaces, not an instant public browser sandbox, so setup, templates, and cloud resources replace CodeSandbox's one-click experience.
How to deploy Coder
Install the Coder control plane, connect PostgreSQL, then provision workspaces from Terraform templates; Helm is available for Kubernetes
What it takes to run
The first obstacle is infrastructure, not the IDE: PostgreSQL, Terraform templates, cloud or cluster credentials, persistent workspace storage, and a reachable TLS URL are required
Where your data lives
Users' source and build artifacts live in the provisioned workspace disks, volumes, or cloud resources; Coder configuration, users, audit/control-plane state, and template/Terraform state live in PostgreSQL
Why fork Coder instead of vibe-coding a CodeSandbox clone?
You can self-host a browser IDE, but fast templates, previews, cloud VMs, collaboration, and workflow integrations are the product.
