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
ai-sync
Cross-platform AI agent synchronization. When you switch between AI coding tools (Claude Code, Cursor, Codex, Aider, Cline, Windsurf, Copilot), ai-sync maintains a shared .ai-sync/ directory so the next agent picks up exactly where the last one left off — with full context of what was done, what's next, blockers, and build status. Features conflict detection, auto-progress tracking, session audit trails, and adapter files for 9 tools.
Delimit
One workspace for every AI coding assistant. Shared tasks, memory, and governance.
