alireza0：S-UI 暂不支持按客户端 IP/设备数限制
alireza0 表示 S-UI 仍不计划加入按客户端 IP 或设备数限制：该功能面向商业场景，会让个人面板更重，可靠实现也需要不同资源与技术栈；需要连接数统计时可开 Clash API，商业限流可考虑 Nx Panel。

Thank you for the kind words, and for taking the time to write this up.
This has been requested several times before, and the answer hasn't changed: a per-client IP/device limit is not planned for S-UI.
- #862, #1268: it is a feature aimed at commercial use. S-UI is designed to stay a lightweight panel for personal use, and this would make it heavier for everyone.
- #995: doing it reliably needs more resources and a different stack than this panel is built on.
- #1161: device binding/restriction is outside the panel's scope.
- #1268: it was also listed for donations at https://donate.alireza0.dev, with no interest so far.
If you only want to see how many connections a client has, you can enable the Clash API and monitor it yourself (#980).
For commercial setups that need IP limits, please have a look at our commercial product, Nx Panel:
