Duel-Agents vs gateway

gateway is much bigger: 12.9k stars against 772. Over the days we have tracked them Duel-Agents moved +10.6% and gateway +3.2%, so Duel-Agents is growing faster right now.

gateway leads on noise control and customization and privacy and model freedom and setup ease. Duel-Agents does not take any axis by a clear margin.

Stars and commit dates come from our own daily tracking. The six axes are read off each project's documentation by our review pipeline, so they describe what a project says about itself, not what we measured in its code.
