Why the models rank Coder — on best cloud development environments for large monorepos

Best overall for organizations willing to operate the platform: self-hosted, infrastructure-agnostic Terraform templates, powerful persistent workspaces, broad IDE support, and freedom to place high-CPU/high-memory machines and caches beside monorepo dependencies.
