Net Nanny focuses on web content filtering. Kidfence is a complete protection layer built for macOS: filtering with no VPN and no slowdown, app and game blocking by code signature, locked DNS and SafeSearch, browser lockdown, and per-app time limits that actually freeze the app, all run as a system service a kid can’t simply switch off.
A lot of Mac filters route traffic through a local VPN or proxy, which can slow the machine down and break on proctored school tests. Kidfence filters at the network layer using a macOS Network Extension and SNI inspection: no traffic is tunneled, HTTPS stays intact, and there’s no remote hop to add lag. The Mac runs exactly as fast as it did before.
Net Nanny is built around web content filtering. Kidfence layers in the protections a determined kid on a Mac actually tests, and runs as a system service so it stays on with the lid closed and can’t be disabled with a new account.
Roblox, Minecraft, Steam, Discord, or any app, blocked by code signature, so renaming the app doesn’t bypass it. Endpoint Security blocks at launch.
Set a daily budget per app and a bedtime window. When time’s up, Kidfence freezes distracting apps in place while schoolwork keeps running, rather than just showing a reminder. Grant 30 more minutes with one message.
Family-safe DNS and SafeSearch on Google, Bing, and YouTube are pinned on at the network layer. They can’t be toggled off in the browser, and manual DNS edits are reverted automatically.
Kids hunt for fresh game, proxy, and unblock sites every week, faster than any fixed list keeps up. Beyond a curated list of roughly 500,000 known sites, Kidfence uses AI to categorize unfamiliar ones on the fly and block games, adult, and proxy sites, so a brand-new URL isn’t an automatic way around the filter.
Kids download Firefox, Brave, or Arc to dodge filters. Kidfence blocks every browser except Safari and Chrome by signature, and disables incognito and private browsing, so there’s no filter-free way around it.
Kids use school Gmail to chat all day. Kidfence’s browser extension hides the Chat, Spaces, and Meet panels while email keeps working, something general web filters don’t touch.
Ask any time for the live list of every tab open right now, with how long they’ve lingered on each. The AI reads it back in plain English, flags a quick break that’s become an hour on a game site, and suggests what to do, plus a daily summary, all end-to-end encrypted.
Both filter the web, but the protection surface is very different. Here’s what each covers on a Mac.

| AI categorizes brand-new / unknown sites on the fly | Yes | Static categories |
| Blocks unauthorized browsers & incognito | By signature | Partial |
| Hides Gmail Chat, Spaces & Meet | Yes | No |
| Kid can’t disable it with a new user account | Yes | No |

No. Kidfence doesn’t tunnel traffic through a remote server. Web filtering happens locally via a macOS Network Extension, and app blocking uses Endpoint Security, which has near-zero overhead. You won’t notice a performance difference.
Yes. Set a daily budget per app and a recurring bedtime window. When the budget runs out, Kidfence freezes distracting apps in place (schoolwork keeps running) rather than just popping a reminder, and everything resumes the next day.
No, you’re getting materially more protection on the Mac. Net Nanny centers on web content filtering; Kidfence adds system-level app blocking by code signature, browser lockdown, locked DNS and SafeSearch, the Gmail Chat block, and per-app limits that freeze the app, all enforced so a kid can’t switch it off. It’s $79.99/year for the whole family, with a 14-day free trial.
There’s no import, but you won’t need one. Setup is a conversation: tell Kidfence “block these sites and apps, two hours a day, bedtime at 9” and it’s done. Most families recreate their whole policy in a couple of sentences.
