Pi-hole, NextDNS, Firewalla — or a box that looks after itself.
Four ways to stop ads and scams on a home network. They work in genuinely different ways, and the right one depends almost entirely on who is going to maintain it. Here is what each one costs, what it actually does, and — in the last section — when the cheapest option is the correct one to buy.
| Cost | How it filters | Who maintains it | Catches scams | Your data | Right for non-technical parents? | |
|---|---|---|---|---|---|---|
| PorchLights | $79 once / ₹1,999 | Two on-device AI models score each address | Nobody, after setup | Yes — that is the primary job | Never leaves the house | Yes, this is the case it was built for |
| Pi-hole on a Raspberry Pi | $35–$70 in hardware, once | Large blocklists of ad domains | You do, forever | Only if you maintain a scam list yourself | Stays local, if you never enable the public lists | Only if you are the one maintaining it |
| NextDNS / AdGuard DNS | $20–$55 per year, ongoing | Cloud resolver with blocklists | Nobody, but you subscribe | Scam-filtering on paid tiers | Every domain query goes to their server | Yes, if the subscription is fine |
| Firewalla | $319 and up | A full network firewall | A technical owner | Not its purpose | Local by default | Overkill for scam blocking |
| Per-device security app | Often free, sometimes a subscription | Installed on each phone and laptop | Everyone, and someone uninstalls it | Partly, on that device only | Varies by vendor | No — this is the thing that gets abandoned |
Competitor pricing from public listings, August 2026. Pi-hole and Raspberry Pi prices vary by region and are hardware costs rather than subscriptions.
If you are technical and will keep it running
Buy Pi-hole. It is cheaper, it is open source, and you already know how to use it. PorchLights will not do anything better for you.
If the whole family must be covered
PorchLights. Router-level, so the TV and the smart fridge are covered too — not just the devices someone remembered to protect.
If nobody in the house will maintain anything
PorchLights. Pre-flashed, no SD card, no console, no lists. And if the blocklist approach already failed once, that failure is the reason this exists.
PorchLights is not a better Pi-hole. It is a different mechanism for a different household. If you can run a Raspberry Pi and keep a blocklist current, Pi-hole is cheaper and you should buy Pi-hole. This page is on our own site, so we have no reason to pretend otherwise. What PorchLights changes is who has to do the work afterwards — and that is the whole question for a house where the victim is your mother.
One known false positive in firmware v0.3a: fonts.googleapis.com, scored 0.4774
against a 0.4774 cutoff. Threshold tuning and a built-in allowlist land in v0.3b. Scam lookups
measure about 4 ms and ad lookups about 1 ms at 160 MHz, with roughly 100 KB
of model on the device. The full register shows real output.
