The verdict
Both are completely free notch tools for approving coding-agent prompts without leaving your workflow, and both cover Codex and Claude Code — the difference is breadth and philosophy. X Island also monitors Gemini CLI and OpenCode and lets you view bypass status as an option. Chimlo sticks to just Codex and Claude Code and is the more conservative of the two by design — bypass mode is never exposed, and it’s open source under GPL-3.0 with scoped, previewed hook installation. Pick X Island if you want the widest agent coverage; pick Chimlo if you want the more cautious approvals model and open-source code you can inspect.
Which one should you pick?
Pick Chimlo if…
- Pick Chimlo if you want bypass mode never exposed as a stated design choice
- Pick Chimlo if open-source code (GPL-3.0) you can inspect matters to you
- Pick Chimlo if you want hook installation previewed and scoped to only Chimlo’s own config entries
- Pick Chimlo if native AppKit/SwiftUI with no Electron shell is a priority
Pick X Island if…
- Pick X Island if you also run Gemini CLI or OpenCode, not just Codex and Claude Code
- Pick X Island if you want to view bypass status directly rather than have it withheld entirely
- Pick X Island if a single Homebrew install command is more convenient than a GitHub download
- Pick X Island if you’re running many hours of daily agent sessions and want the more keyboard-driven of the two
