Best Website Blocker
Best website blocker: top picks
The best website blocker for most remote workers is Freedom: it runs one synced session across Mac, Windows, iOS, Android and Chromebook, so the block follows you when distraction moves from laptop to phone. LeechBlock NG is the best free option for browser-only distraction, and Cold Turkey Blocker is the strongest desktop pick when blocks must not be cancellable mid-session.
This guide compares the blockers worth installing, explains how we chose them, and gives you the buying criteria to pick the right one for where your attention actually leaks. A blocker is one branch of the category: our focus apps hub covers the wider landscape, including timers and attention trackers, and the productivity tools hub maps where blocking fits in the rest of a remote-work stack.

Best overall: Freedom
Freedom blocks websites, desktop apps, or the entire internet across Mac, Windows, iOS, Android and Chromebook, with one blocklist and one session state synced across all of them. That cross-device sync is the whole reason it tops this list. For a remote worker, the distraction loop usually runs laptop to phone and back: you block Twitter on the laptop, and the scroll continues in your pocket. Freedom closes both doors with one session, and on Mac and Windows it blocks desktop applications, not just browser tabs, so chat tools and games go dark during a session rather than merely feeling discouraged.
The free plan is genuinely usable rather than a demo: unlimited manual sessions, custom blocklists, desktop app blocking, focus sounds and full cross-device sync at no cost. Premium (at the time of writing, $3.33 per month billed yearly or $8.99 month to month, with a lifetime option) adds the automation layer: scheduled and recurring sessions, sessions longer than two hours, and Locked Mode, which prevents ending a session early. For the full breakdown of plans, quirks and setup, see our Freedom app review.
Best value: LeechBlock NG
LeechBlock NG is a free browser extension for Firefox, Chrome and Edge that quietly does most of what paid blockers charge for: timed block sets, schedules, delay pages, and rules like “allow this site for five minutes per hour.” There is no paid tier, no account and no upsell, which makes it the best free starting point for anyone whose distraction problem is confined to the browser.
The limitation is structural: it lives only in the browser, so your phone remains a loophole and native apps stay reachable. If your distraction happens in tabs during work hours, though, it is a remarkable amount of enforcement for $0, and it costs nothing to find out whether blocking changes your behavior before you consider a paid tool.
Best by use case: quick map
- Distraction across phone and computer: Freedom, whose one-session-everywhere sync is the category’s defining capability.
- Desktop-only hard blocking: Cold Turkey Blocker on Windows or Mac, whose Pro blocks can be locked so they survive your 2 p.m. self.
- Phone-first distraction: Opal for a hard screen-time block on iPhone and Android; see our Opal review for where it wins and where it frustrates.
- A lighter pause instead of a wall: one sec, which inserts a breathing screen before an app or site opens, enough to break autopilot scrolling without hard enforcement.
- Zero budget, browser-only distraction: LeechBlock NG.

Three honest notes on that table. First, prices in this category move often and app-store listings differ from vendor websites, so check current pricing before you buy. Second, “free plan” means very different things: LeechBlock’s free tier is the full product, while Opal’s free tier is a taste of the paid enforcement. Third, the platform column matters more than the price column: a cheaper blocker that misses the device where you actually scroll is the more expensive choice.
How we chose and evaluated
This is an evaluation of published vendor documentation and current pricing, not a claim of long-term laboratory testing; the judgment layered on top is ours, and every recommendation had to pass the same test: would it survive contact with a remote worker at their weakest moment? Concretely, we evaluated five things.
Block quality. Hard blockers remove access entirely; soft blockers add a step, a delay, or a question. Neither is strictly better. Soft blockers interrupt autopilot, which is what most doomscrolling is, while hard blockers guard the hours you already decided to protect. We favored tools that do both or make the choice explicit.
Device coverage. A blocker that lives only on your laptop is a blocker with a loophole named “your phone.” We weighted tools that reach the device where the distraction actually happens, which is the single biggest differentiator in this category and the main reason price tiers exist.
Scheduling and defaults. Scheduled blocking runs whether you feel like it or not. On-demand blocking starts when you notice you need it, which is exactly when you are least reliable. Tools that make the schedule the default scored higher.
Friction cost to you. A blocker should be invisible while you work and immovable while you are not. Anything that nags, demands attention, or slows normal work gets deleted within a month, so we discounted tools with high maintenance costs.
Price model. Free, one-time purchase, or subscription, and whether the paid tier buys something real. We checked current prices on each vendor’s own pricing page at the time of writing.
Best options by use case
Cross-device distraction: Freedom
If your attention leaks across phone and computer, Freedom is the strongest fit because the synced session closes both at once. Set up two or three blocklists (deep work, after-hours, social), install on every device you work from, and schedule recurring sessions over your known weak windows. After that, the product is designed to be forgotten. The honest caveat: Locked Mode raises friction against quitting but is not tamper-proof, since a determined user can still uninstall or change device settings. That is true of every consumer blocker, and it is worth knowing before you buy.
Desktop hard blocking: Cold Turkey Blocker
Cold Turkey is the strictest option for Windows and Mac. Its defining feature is the lock: you can make a block immovable until the timer expires, so the version of you at 2 p.m. cannot cancel the promise the version of you at 9 a.m. made. It blocks websites and desktop applications, and its free tier covers basic site blocking, with Pro as a one-time purchase rather than a subscription. There is no phone app, so it suits workers whose distraction is entirely on the computer, and it is the pick for anyone who has already proven that softer tools do not hold.
Browser-only distraction: LeechBlock NG
If the problem is confined to browser tabs, LeechBlock NG covers it for free with more flexibility than most paid tools: per-hour allowances, scheduled windows, delay pages and multiple block sets. It is also the right first experiment for anyone unsure whether blocking helps at all, because the cost of finding out is zero. Its weakness is the one you would expect: the phone in your pocket is unaffected.
Phone-first distraction: Opal and one sec
If the phone is the actual problem, a desktop blocker is the wrong purchase. Opal enforces hard screen-time blocks with a Deep Focus mode that resists being skipped, and it scores your day, which some people find motivating and others find nagging. one sec takes the opposite approach: a breathing screen and a deliberate pause before a blocked app opens, which is often enough to interrupt the autopilot loop without the withdrawal of a hard wall. Try the free tiers of both before paying; the right choice is about your psychology, not their feature lists.
When a blocker is the wrong category entirely
Two failure modes send people to blockers who need something else. If your real problem is that your day has no structure, so the distraction is wherever the unstructured moment lands, the fix is scheduling: our guide to calendar apps covers time-blocking approaches that shrink the gaps a blocker would otherwise have to defend. And if your problem is that work has no start ritual at all, no blocker will manufacture one. Diagnose before you subscribe; a blocker defends a plan, it does not create one.
What to look for before buying
Key features
- Coverage on the device where distraction happens. Check your screen-time report first: the blocker must reach that device, or it is decorative.
- Both block styles. Hard blocking for protected hours and a soft pause for autopilot moments cover the two failure modes; a tool that does only one limits you.
- Scheduling and recurring sessions. Automation beats willpower. A blocker you have to start by hand is competing for the exact resource you are short of.
- Desktop app blocking. Websites are half the problem on a computer; Slack, games and email clients are the other half.
- Allowlist mode. Blocking everything except a short list of work sites is usually more practical than maintaining an infinite blocklist.
Workflow fit
Match the tool to how you fail, not to the longest feature list. If you work from one laptop all day, a browser extension may be all you need, and paying for cross-device sync buys nothing. If your workday runs on a Mac and your evenings on an iPhone, cross-device sync becomes the core feature rather than a bonus. If you share a machine or cannot install software on a work computer, browser extensions and router-level or DNS-level blocking are the realistic paths. And if your employer already provides device management, check what is allowed before buying anything.
Price and value
The category prices range from $0 (LeechBlock, Freedom’s free tier) to roughly $8 to $10 per month for phone-first apps. One-time purchases like Cold Turkey Pro make sense if you expect to block for years; subscriptions make sense while you are still testing which enforcement style works for you. Value is not the sticker price but whether the paid tier fixes your specific failure: paying for scheduling when your problem is quitting sessions early is the right trade, and paying for analytics when you already know where you waste time is not.
Limitations
Every consumer blocker shares one: it can be defeated by the person who installed it, through device settings, uninstalling, or a second device left out of the block. Blockers raise friction, and friction is usually enough, but nothing at this price guarantees compliance. Beyond that, free tiers are often limited in exactly the features that automate behavior (scheduling, locking, sync), phone-side allowlists are rarer than desktop ones, and Linux support is thin across the category. None of these are disqualifiers; they are the realistic edges of what the product does.
Value, pricing and trade-offs
The value math in this category starts at zero. LeechBlock NG covers browser-bound distraction for nothing, and Freedom’s free plan is the rare free tier that includes the flagship feature (cross-device sync) rather than gating it. That means your first two weeks should cost nothing regardless of which tool you eventually keep.
Where money is justified: Premium Freedom ($3.33 per month billed yearly at the time of writing) buys scheduled and recurring sessions and Locked Mode, which is worth it precisely when your failure mode is starting or keeping sessions. Cold Turkey Pro (about $39 once) is worth it for anyone who has proven that softer tools do not hold and wants the strictest desktop enforcement without a subscription. Phone-first apps charge more for less coverage, which is defensible only when the phone is genuinely the whole problem.
The trade-off worth naming: enforcement versus autonomy. The harder the block, the more it protects you from your weak moments and the more it frustrates your strong ones, when a legitimate work site sits behind a wall. Tools with granular schedules and allowlists reduce that cost. Whichever tool you pick, verify current prices on the vendor’s own pricing page before buying, because this category reprices often and app-store listings lag.

Frequently asked questions
What should I look for in best website blocker?
Coverage first: the blocker must run on the device where your distraction actually happens, which a screen-time report reveals in two minutes. Then look for both hard and soft blocking styles, scheduled or recurring sessions so enforcement does not depend on willpower, desktop app blocking rather than browser-only coverage, and allowlist mode for letting a few work sites through. Price matters less than fit; the best free options cover browser-bound distraction completely, and paid tiers buy cross-device sync and automation.
How do I choose the right option?
Start with a free tier and a diagnosis. Look at where you lose the most time: browser tabs, phone apps, or desktop applications. Distraction spanning phone and computer is Freedom’s specific strength, because one session syncs everywhere. Phone-first distraction points to Opal or one sec. Run the free plan for two weeks with one blocklist over your top three distractions, and pay only for the feature your failure mode actually requires.
What do people usually get wrong when picking best website blocker?
Three common mistakes. First, buying coverage they do not need: paying for phone syncing when the distraction lives entirely in desktop browser tabs. Second, overestimating enforcement: every consumer blocker can be defeated by the person who installed it, so expecting a hard block to be tamper-proof sets you up to abandon the tool after one bypass. Third, using a blocker to solve a scheduling problem: if your day has no structure,the gaps win, and no blocklist fixes that.
