AI-Powered DevContainers

Overview

Infrashift DevContainer Features includes first-class support for AI coding assistants. Run Claude Code or OpenAI Codex directly inside your development container with full access to your project files, terminal, and development tools.

Why AI Assistants in DevContainers?

DevContainers provide the ideal environment for AI coding assistants:

• Isolation: AI agents operate within a container boundary, not on your host machine
• Reproducibility: Every team member gets the same AI tooling configuration
• Security: Combine with egress filtering to control what domains AI agents can access
• Consistency: Pin specific versions of AI tools across your team
