Coder offers a self-hosted platform for secure, ephemeral cloud development environments and AI coding agents. It targets engineering teams needing standardized setups, rapid onboarding, and secure AI integration, providing centralized control over infrastructure and AI execution for data privacy and cost efficiency.

How It Works

Infrastructure for workspaces (EC2, Kubernetes, Docker) is defined using Terraform. Secure access is provided via WireGuard tunnels, with idle resources automatically shut down for cost optimization. Coder Agents execute AI coding loops on-premise, eliminating workspace API keys and enabling centralized governance, cost tracking, and audit logging for AI model usage.

Quick Start & Requirements

Linux/macOS installation uses curl -L https://coder.com/install.sh | sh; Windows uses a GitHub Releases installer. Local testing involves coder server (data in ~/.cache/coder) and accessing http://localhost:3000. Production requires PostgreSQL (v13+) and an external URL (coder server --postgres-url <POSTGRES_URL> --access-url <ACCESS_URL>). Docs: coder.com/docs.

Highlighted Details

• Self-hosted cloud development environments managed via Terraform.
• Secure workspace access through WireGuard tunnels.
• Automatic shutdown of idle development resources for cost savings.
• Native AI coding agents execute on-premise, with no LLM credentials exposed in workspaces.
• Support for diverse LLM providers including Anthropic, OpenAI, Google, Bedrock, and self-hosted models.
• Centralized governance, cost tracking, and audit logging for AI model usage.
• Integrations for VS Code, JetBrains IDEs, and Dev Containers.
