Net Nanny vs Covenant Eyes: Filtering or Accountability?

Short answer: these two are not competitors. Net Nanny is a real-time content filter — it inspects pages as they load and stops the bad ones reaching the screen. Covenant Eyes is an accountability service — it records what was on screen and reports it to a person the user has chosen. Choosing between them is choosing which model you want, not deciding which product is better.

Get the model right and either can work well. Get it wrong and you pay for twelve months of software that does not address the thing you were worried about. So this comparison starts with the mechanism, spends the middle on price, platforms and what each actually catches, and ends with three concrete family situations rather than a scorecard.

The mechanism difference in one paragraph each

Net Nanny filters, in real time, before the page renders. Its engine analyses page content as it loads and categorises it — pornography, gambling, weapons, drugs, and so on — then blocks or allows according to the settings you chose per child. Because it works on content rather than a fixed list of URLs, it can block a site nobody has ever catalogued. Nothing has to be reported afterwards, because in the intended case nothing was seen.

Covenant Eyes reports, after the fact, to a human being. It periodically captures what is on the screen, analyses those images, and sends a report to a nominated accountability partner — a spouse, a mentor, a friend, a parent. Its filtering exists too, but the accountability record is the product. The behaviour change comes from a specific person seeing the report, not from software blocking anything. That is a relationship mechanism with software attached, and it works or fails on the relationship.

Once that is clear, most of the "which is better" question dissolves. A filter cannot make a seventeen-year-old accountable. An accountability report cannot stop a seven-year-old seeing something at 4pm on a Tuesday.

Net Nanny vs Covenant Eyes: side by side

Net Nanny Covenant Eyes 3Eyes (allowlist model)
Core model Real-time content filtering Screen-capture accountability reporting Preventive allowlist filtering
When it acts Before the page loads After it was on screen Before the page loads
Who it talks to The parent, via settings and alerts A chosen accountability partner The parent, via approve/deny requests
Blocking approach Category-based blocklist with live content analysis Filtering available; accountability is the focus Approved list — unknown sites fail closed
Platforms Windows, Mac, iOS, Android, Kindle Fire Windows, Mac, iOS, Android Windows and Mac for the child; parent app is iOS-first
Screen time controls Yes — schedules and time limits Not its focus Yes — daily limits and scheduled downtime
Reporting Activity reports and alerts to the parent Periodic activity report to an ally Approve/deny requests; no content log
Unsupported browser Depends on platform hooks; can be a gap Still captured — it captures the screen, not the browser Unapproved applications don't run
Consent model Parent-imposed Mutual and consensual by design Parent-imposed
Pricing model Annual subscription, tiered by device count Household subscription, monthly or annual $16.99/mo or $169.90/yr, up to 4 children
Best for Filtering for children across mixed devices Older teens and adults in a consenting accountability relationship Younger children on a home computer

Both vendors change tiers and run promotions frequently, so check the current number on each vendor's own pricing page rather than trusting any comparison article, this one included. The durable point is structural: both are annual household subscriptions in broadly the same bracket, and the price difference between them is not large enough to decide anything. Model fit is what you are actually choosing.

Net Nanny: what it does well, and what reviewers complain about

Net Nanny is one of the oldest names in the category and its content-analysis filtering remains its genuine strength. Filtering by what a page contains rather than by a list of known URLs is the right architecture for the problem, because the list of sites you would want blocked is infinite and nobody maintains a complete one. It handles a site that appeared last week better than a plain domain blocklist does. The per-child category settings are granular, the screen-time scheduling is solid, and it covers a wide platform spread including Kindle Fire, which most competitors ignore.

What reviewers commonly report as frustrations:

  • False positives. Aggressive category filtering blocks pages that were fine — a school research topic caught by the "weapons" or "drugs" category is the classic example. Tuning per-child categories reduces it; it doesn't eliminate it.
  • Per-device pricing adds up. The tiers are counted in devices, and a family with a laptop each, phones and a tablet moves up a tier quickly.
  • iOS limitations. Apple's platform restricts what any third-party filter can do, so iOS coverage is weaker than Windows or Android. This is a constraint on the whole category, not a Net Nanny failing.
  • Performance and setup friction. Real-time page analysis has a cost, and reviewers periodically report slowdowns or awkward installs.

Covenant Eyes: what it does well, and what reviewers complain about

Covenant Eyes has a clearer sense of what it is for than almost anything else in this market, and that focus is the reason it works for the people it works for. Because it captures the screen rather than hooking a browser, it is not defeated by using an unusual browser, an app with no API, or a private window — if it was on the screen, it is in the record. It is one of very few tools designed for adults monitoring themselves, which makes whole-household accountability possible in a way parent-child products cannot manage. And the honesty of the model is structural: everyone knows it is there, because being known is how it works.

What reviewers commonly report as frustrations:

  • Invasiveness. Screen capture is the most intrusive mechanism in this comparison. That is a deliberate design decision, not a flaw, but it is a real cost and it is the thing people object to.
  • Narrow scope. It is not a broad parental control suite. Screen-time management, app limits and YouTube curation are not what it is for, so a parent expecting a full toolkit is disappointed.
  • Battery and performance on mobile. Continuous capture and upload has a cost, and reviewers report it.
  • It reports rather than prevents. On the accountability side, by the time the ally sees the report, the thing has happened. The filtering is a separate mechanism from the accountability record.
  • It needs a real partner. Nominating an ally who never reads the reports produces a subscription and no accountability. This is the most common way it fails, and it is not a software problem.

Our Covenant Eyes alternatives guide covers the options when the model fits but the product doesn't, and Bark vs Covenant Eyes sets it against the monitoring-and-alerting model instead.

Three families, three answers

The Patels: two children, aged 7 and 10, one shared family laptop and a tablet. They want the children not to stumble into pornography, and they want the tablet off at 8pm. There is no accountability relationship to build here — a seven-year-old cannot meaningfully consent to or engage with one. Net Nanny fits, or an allowlist tool. Covenant Eyes would be both invasive and beside the point at this age.

The Osbornes: a 17-year-old who has asked for help with a pornography habit, and a father who has said he will do it alongside him. The son does not need to be blocked; he needs someone to see. That is exactly the mechanism Covenant Eyes is built on, and the mutual-consent design means it is not something being done to him. Covenant Eyes fits. A filter here would be trivially bypassed by a motivated seventeen-year-old and would communicate distrust rather than support.

The Warrens: a 12-year-old with a school Chromebook, a home PC and a phone, whose parents want time limits, content filtering and some visibility. This is the mixed case, and it is the most common. They want prevention on the PC, limits on the phone, and no realistic accountability relationship yet. Net Nanny fits better than Covenant Eyes, but the honest answer is that the school Chromebook will be managed by the school regardless, and no consumer product covers it — a router-level filter is the piece that reaches everything.

The pattern across all three: age and consent decide the model. Under about eleven, filter. Over about sixteen with a willing participant, accountability. In between, filtering plus a conversation, and expect to shift models as they get older.

Where 3Eyes fits — and where it doesn't

3Eyes is a filter, and specifically an allowlist filter. Approved sites and applications load; everything else shows an "Ask Parent" page rather than being scored by a category engine. That is a different bet from Net Nanny's: instead of trying to recognise every bad site, it declines everything unknown. It also handles daily time limits and scheduled downtime, runs on Windows and Mac as a managed service that resists being closed from a standard account, and sends approval requests to a parent's phone. It costs $16.99 a month or $169.90 a year for up to four children, with a 14-day trial.

Where it fits: a primary-school or early-secondary child on a home computer, where "only the things I have approved" is a reasonable rule and the friction of approving things is acceptable.

Where it explicitly does not fit: it is not an accountability product. It does not capture your screen, it does not produce a record of what was viewed for a partner to read, and it is not built for an adult monitoring themselves. If the accountability model is the one you want — a trusted person seeing a report because you asked them to — Covenant Eyes is a better fit and you should buy Covenant Eyes. An allowlist aimed at a consenting adult is just an inconvenience they can turn off.

It is also the wrong tool for a teenager who needs a broad open internet for schoolwork and a social life. Allowlisting a fifteen-year-old produces either an approval queue nobody can keep up with or a child who works around it. Our Christian parental controls comparison covers the faith-focused end of this market, where both Covenant Eyes and filtering tools are commonly considered together.

Frequently asked questions

Is Covenant Eyes a parental control? Not primarily. It is an accountability tool built around reporting screen activity to a chosen partner, widely used by adults for themselves. It can be used with an older teenager who consents, but it lacks the screen-time and app-management features parents usually expect.

Does Net Nanny work on iPhone? It has an iOS app, but Apple restricts what any third-party filter can do on iOS, so coverage is weaker than on Windows or Android. This is a platform limit affecting the whole category, not something one vendor has solved.

Can I use both Net Nanny and Covenant Eyes? Yes, and some households do — filtering for younger children, accountability for an older teenager or a parent. Running both on the same device is technically possible but adds performance cost and configuration complexity for little gain.

Which is cheaper, Net Nanny or Covenant Eyes? They sit in a similar annual bracket, and the answer changes with tiers, device counts and promotions. Check both vendors' current pricing pages. Over the five or six years you will run something like this, model fit costs far more than the price gap.

Does Covenant Eyes block websites? It includes filtering alongside the accountability reporting, so it can block. But the reporting is what the product is designed around; if blocking is your main goal, a filter-first product is the better match.
