This author has tested a lot of IP KVMs and compares them in this post: https://www.jeffgeerling.com/blog/2026/i-tested-every-ip-kvm...

He likes JetKVM. However, they appear to be sold out. The Mini seems great but I have yet to receive a preordered item on the advertised timeline.

That article pointed to ArkKVM which is a hardware clone of JetKVM but they have now released their own software stack as open source which has Tailscale support
