The 9 Best Porn Blockers in 2026

Blockers stop porn from loading. Ascension, Cold Turkey and Cisdem AppCrypt work this way. BlockerX is a blocker that can also alert a partner.

Accountability apps send a record of your activity to a person you choose, and mostly do not stop you from opening a page. Covenant Eyes and Accountable2You work this way.

Parental filters block content on a device that someone else controls. Canopy, Qustodio and Net Nanny work this way.

Pros

• ✓Strong enforcement: closing the app does not lift an active block.
• ✓Uninstall protection: a block can be set so Ascension cannot be uninstalled while it runs.
• ✓Browser protection: a browser without Ascension's protection is closed while a block is active.
• ✓Blocking precision: whole sites, sections of a site, search terms and keywords.
• ✓Privacy: all data stays on your computer.

Cons

• —Windows only: iOS and Mac are in development, so your phone is not covered yet.
• —No accountability partner: it does not send reports to another person.

Pros

• ✓Real accountability: a specific person seeing the report is a deterrent no blocker replicates.
• ✓Catches what filters miss: screenshot analysis covers apps and private windows, not just website traffic.
• ✓Every device: Windows, Mac, iPhone and Android on one subscription.
• ✓Whole household: one subscription covers up to ten users in a family.
• ✓Established: sold since 2000, and the most widely recommended accountability app.

Cons

• —Light blocking: the filter is the secondary product, so in the moment itself very little is in your way.
• —Heavy privacy cost: continuous screenshots capture banking, work and private messages alongside everything else.
• —Depends on your ally: when they stop reading the reports, the system quietly stops working.
• —Most expensive here: $18 a month with no end date, or $950 once.
• —False flags: innocent images get flagged and land in a report you then explain.

Pros

• ✓Filters sites nobody listed: image and page level analysis catches what blocklists structurally cannot.
• ✓Every major platform: one subscription across desktop, mobile and ChromeOS.
• ✓Tamper alerts: attempts to disable it notify the account holder.
• ✓Per person settings: different filter levels for different people in a household.
• ✓Money back guarantee: 30 days to change your mind.
• ✓States its browser support: Chrome, Edge, Firefox, Brave and Safari, which most vendors here do not publish.

Cons

• —Built for parents: the model assumes someone else holds the controls, which is awkward when you are both.
• —Filtering is not enforcement: an adult with admin rights on their own machine is a different problem from a child.
• —Subscription only: no one time purchase at any tier.
• —No usage insight: it filters content and tells you nothing about your patterns.

Pros

• ✓Blocks and notifies: the block and the partner alert in one subscription.
• ✓Strong mobile coverage: Android and iOS are first class rather than an afterthought.
• ✓No screenshots: your partner is told about attempts, not shown your screen.
• ✓Lifetime option: $199.97 once, against Covenant Eyes at $950.
• ✓Habit tools included: streaks and community features bundled in.

Cons

• —Mobile first: the Windows product is lighter than dedicated desktop blockers.
• —Medium enforcement: bypass resistance on desktop is well short of the strongest options here.
• —Aggressive upselling: the free tier pushes hard toward premium.
• —Basic reporting: usage figures exist but there is little to learn from them.
• —Read the lifetime terms: BlockerX defines its lifetime plan as five years.

Pros

• ✓Very strong enforcement: multiple lock types, and an active block is deliberately painful to undo.
• ✓Blocks desktop apps too: not just browser traffic, which Ascension does not do.
• ✓One time price: $45, and one key covers every computer you own, Windows and macOS.
• ✓Publishes its browser list: 24 browsers on Windows, including Firefox, Brave, Opera and Vivaldi, the widest stated coverage here.
• ✓Complete privacy: nothing captured, uploaded or shown to anyone.
• ✓A decade of development: mature and stable.

Cons

• —No accountability at all: nobody is told anything, ever.
• —No mobile app: the phone is untouched.
• —Lockouts cut both ways: a locked block on a work machine is locked for work too, so set schedules carefully.
• —No adult content category out of the box: you build or import the list yourself.

Pros

• ✓Cheaper than Covenant Eyes: $11 a month for the same model, or $16 for a family.
• ✓Widest platform list here: the only one with a native Linux app.
• ✓Text rather than screenshots: the company states plainly that it decided not to include screenshot accountability, so activity is described and never photographed.
• ✓Per device partners: different people can be assigned to different devices.
• ✓Instant alerts: flagged activity notifies immediately rather than waiting for the weekly summary.

Cons

• —No blocking at all: monitoring only, so nothing is ever in your way.
• —Same dependency: it stops working the moment your partner stops reading.
• —Install limits: six active installs on the personal plan, twenty on family.
• —Report fatigue: a detailed log of everything you do is a lot to read every week, for both of you.

Pros

• ✓Cheapest paid option: $19.99 a year, or $39.99 once, the lowest one time price here.
• ✓Category blocking: adult, social, gambling and others without building a list yourself.
• ✓Keyword filtering: blocks URLs containing chosen words, not just exact domains.
• ✓App lock included: password protects applications as well as blocking sites.
• ✓States its browser support: Chrome, Edge, Firefox, Opera and Brave on Windows, through its own extension in each.

Cons

• —Password protection is the ceiling: the lock is only as strong as your willingness not to type the password.
• —Desktop only: no mobile app.
• —No accountability: nothing is reported to anyone.
• —Generalist tool: built for productivity and parental use, not specifically for this problem.

Pros

• ✓Strong category filtering: mature web filtering across devices.
• ✓Covers the whole family: five devices on Basic, unlimited on Complete.
• ✓Free tier exists: one device with basic features, permanently.
• ✓Detailed reporting: activity summaries and alerts to the account holder.
• ✓Cross platform: desktop and mobile on one subscription.

Cons

• —You have to hand over the controls: without a second person holding the parent account, you can simply turn it off.
• —Not built for adults: the entire product assumes a supervisor and a supervised.
• —Annual billing on paid plans: no monthly option.
• —Overkill: much of what you pay for is location tracking and message monitoring you do not need.

Pros

• ✓Content analysis rather than a list: it can filter a page nobody has categorised yet.
• ✓Long track record: one of the oldest filtering products still actively sold.
• ✓Category and time rules together: filtering, screen time and reporting in one subscription.
• ✓Per person profiles: different settings for different family members.
• ✓Alerts: the account holder is told when blocked content is attempted.

Cons

• —Built for supervision: as an adult filtering your own machine, you hold the account that turns it off.
• —Subscription only: no one time purchase, and no free trial is offered.
• —No Android: the vendor states Android, Kindle Fire and Chromebook are not supported.
• —No self-control features: nothing here is designed to stop the person holding the password.
• —Reporting is for a parent: the summaries are written for someone watching another person.

Microsoft Family Safety. Built into Windows 11 and free. Microsoft's own documentation says web and search filters require a supported browser, currently Edge, with the family member signed in to a Microsoft account. With filtering on, unsupported browsers are blocked outright, but they can be unblocked again from the same settings on the device. It is designed for a parent restricting a child's account, and on your own machine you hold the password to the settings.

DNS filtering: CleanBrowsing, OpenDNS FamilyShield, Cloudflare for Families. Free, changes one setting, and blocks adult websites in every browser and app on that connection at once. The addresses are 185.228.168.168 for CleanBrowsing's family filter, 208.67.222.123 for OpenDNS FamilyShield, and 1.1.1.3 for Cloudflare's malware and adult content filter. CleanBrowsing's free tier is throttled and its paid plans start at $8.99 a month. Three limits: you can undo it in the same place you set it in about a minute; it stops applying on a different network or through a VPN; and a browser can be set to send its DNS lookups over HTTPS to its own resolver, which skips the filter you set on the device, so you have to switch that off in each browser. It is still the best free porn blocker for a PC as a first layer, and the easiest one to reverse.

The hosts file. Free and built into Windows. It blocks a list of domains you type yourself, takes minutes to edit, seconds to undo, and does nothing about searches or domains you have not listed.

Free browser extensions. They work inside the one browser they are installed in, and they can be removed in a click or sidestepped by opening a different browser.

Free options create friction, which is enough for someone drifting into a habit. It is not enough for someone actively looking for a way around, which is the situation most people are in by the time they search for a blocker.

If you want to block porn on a Windows PC with strong enforcement, choose Ascension or Cold Turkey. Ascension comes with premade adult content categories and can be set so it cannot be uninstalled while a block runs.

If you want to be held accountable by another person, choose Covenant Eyes or Accountable2You. Accountable2You costs less.

If you want to block porn on your phone, choose BlockerX or Canopy.

If you want a free option, use DNS filtering on your computer or router. Anyone with access to the settings can turn it off.
