About Coder
Coder is listed in our coding category and is aimed at builders. Self-hosted cloud development environments for developers and their coding agents. Pricing, as the maker states it: Open source + cloud. Maturity: Mature. We last checked the official link on 2026-10-16.
What is Coder?
Coder is a self-hosted platform for cloud development environments and AI coding agents. Workspaces are defined in Terraform (EC2 VMs, Kubernetes pods, Docker containers and more), connected through a secure WireGuard tunnel, and automatically shut down when idle.
Coder Agents runs a native AI coding agent whose loop executes in the control plane on your infrastructure, with no API keys in workspaces. It supports any model (Anthropic, OpenAI, Google, Bedrock or self-hosted) with centralized model governance, cost tracking and audit logging.
