Lines where the two differ have a tinted background and bold values. Where the data itself says which value is better (more marketplaces, a larger figure of the same marketplace, a fresher release, a verified mark on a marketplace that lists both), the better one is also marked green with ▲ and the worse one red with ▼. Where it runs, the transport, the tools, the settings, hooks, the bundle's parts, the licence and the week's changes are marked only as different: more or fewer is not better in itself.
What each says it does
Zen
Bridges multiple AI models and CLIs, enabling orchestrated workflows across Claude Code, Gemini CLI, Codex CLI, and other AI development tools.
claude-codex-loop
claude-codex-loop orchestrates a structured collaboration loop between Claude Code (designer/reviewer) and OpenAI Codex (auditor/implementer). It runs two stages — design and code — each with up to 5 rounds of iterative review plus an independent validation pass. How it works: - Brainstorming (optional) — Explore requirements interactively before designing - Design stage — Claude Code writes a spec, Codex audits it independently each round until convergence - User gate — You review and approve the design before any code is written - Code stage — Codex implements, Claude Code reviews the full diff each round - Independent validation — A separate audit pass with zero prior context to catch groupthink All work happens on a dedicated branch. Cancel anytime with /cancel-review to cleanly restore your starting state. Commands: /review-loop <task>, /cancel-review
