Last I tried Technitium, it took over 100ms to resolve domain names that take 1ms otherwise.

Even if that were true, it would not matter since the source code is open and you can take a look at it to put this phobia of yours to rest.

Also FYI, AdGuard is based in Cyprus.

With AdGuard Home you don’t even need to have log files, there’s built in options to store it in-memory.

Tried all three over the years… I have to say AdGuard Home due to how feature-rich it is. Currently have two instances running, one at home the other for remote usage. AGH is better than the other two at nearly everything.
