DNSight vs Pi-hole
Pi-hole is genuinely good software, and free. If you want network-wide ad blocking on hardware you control, it is hard to beat. The difference is what you get afterwards: a query log, or an account of the day.
What Pi-hole does well
Let us be fair, because the honest version is more useful than the marketing one. Pi-hole is free, open source, self-hosted and mature. Your data never leaves your house. It blocks ads network-wide from a Raspberry Pi that costs less than a month of most subscriptions. For a technical person who wants control and privacy, that combination is excellent.
Where it stops
Pi-hole answers "was this domain blocked?" extremely well. It does not try to answer "what was someone doing?" — and that is the question most people actually open the dashboard for.
A Pi-hole log of an evening looks like several thousand lines of hostnames in time order. Somewhere in it is the fact that someone downloaded a dating app and verified a phone number. Finding that means knowing that rupload.facebook.com is an upload endpoint and that a Twilio lookup next to a first-ever app domain means a signup.
Two other practical limits
- It stops at the router. Every device behind the LAN appears as one client unless you do extra work, so you cannot separate the child's iPad from the TV.
- It stops at the front door. A phone on cellular data is not behind your Pi-hole at all, which is most of a teenager's day.

Which should you use?
Stay with Pi-hole if you want free, self-hosted blocking, you are comfortable maintaining it, and a query log is the level of detail you need. It is the right answer for a lot of people, and running both is perfectly reasonable.
Look at DNSight if you need to tell devices apart, if the devices leave the house, or if you want the log turned into something readable without becoming a DNS expert yourself.
Common questions
- Can I run Pi-hole and DNSight together?
- Yes. A common setup is Pi-hole for the home LAN and DNSight on phones and laptops so coverage continues on cellular data and other networks.
- Is Pi-hole better for privacy?
- For data locality, yes — nothing leaves your network. DNSight is a hosted resolver, which is the trade you make for per-device identity and coverage away from home.
- Does DNSight need a Raspberry Pi?
- No hardware at all. It is a configuration profile on the device, or a DNS setting on your router if you want whole-home coverage.
- How much history does DNSight keep?
- 30 days on every plan, mirrored so it stays queryable after the upstream resolver has rotated its own logs.
