Custom Configuration Directory

By default, Codex stores its configuration and session data in ~/.codex. If you have configured a custom location using the CODEX_HOME environment variable, Vibe Kanban will automatically detect and use that location.

bash

# Example: Using a project-specific Codex configuration
export CODEX_HOME=/path/to/custom/codex
npx vibe-kanban

This is useful for:

Project-specific Codex profiles
Separating work and personal configurations
Custom automation setups
