Aperture CLI is a Tailscale launcher that connects coding agents (Claude Code, Gemini CLI, Codex, OpenCode, GitHub Copilot CLI, and others) to Aperture endpoints.

It handles agent installation, provider and model configuration, and environment setup across multiple AI providers. Bridge mode routes connections through an embedded Tailscale node without requiring the full Tailscale client, and all settings are available as scriptable command-line flags.
