Coder is hiring: 26 open roles
Overview
Coder provisions cloud development workspaces from Terraform templates (EC2 VMs, Kubernetes Pods, Docker containers), connects them over a WireGuard tunnel, and shuts them down when idle. Coder Agents runs an AI coding agent loop in the control plane, so workspaces hold no LLM API keys. It accepts Anthropic, OpenAI, Google, Bedrock or self-hosted models.
Who it is for: Platform teams running self-hosted dev environments and AI coding agents
Strengths
- Workspaces defined in Terraform, so any infrastructure Terraform supports can host them
- Agent loop runs in the control plane; no LLM credentials stored in workspaces
- Idle workspaces shut down automatically to cut compute cost
- Built-in database for evaluation; PostgreSQL 13+ for production
Weaknesses
- Premium tier gates features aimed at large teams, plus dedicated support
- AGPL-3.0 license may be a problem for some organizations
- Production use needs PostgreSQL and an external access URL
- Templates require Terraform knowledge to write and maintain
What it needs
- no GPU
- Compose
- Needs PostgreSQL 13+ (production), Terraform
- Models: Anthropic, OpenAI, Google, Bedrock, self-hosted
- port 3000
