How to Block Roblox on PC, Laptop & Mac (2026 Guide)

There are two Robloxes on a computer, and most parents only block one of them. There is the desktop app (RobloxPlayerBeta.exe on Windows, RobloxPlayer.app on Mac), and there is roblox.com in a browser, which needs no installation at all. Uninstall the app and your child is playing again in ninety seconds through Chrome. Block the website and the installed app keeps working.

This guide covers every method that actually blocks both — built-in Windows and Mac controls, the hosts file, your router, DNS filtering and parental control software — with exact menu paths for Windows 11, Windows 10 and macOS, the full list of Roblox domains to block, and an honest account of how kids get around each one.

Which Method Should You Use? A Quick Comparison

Every method below works. They differ in how long they take to set up, how much of Roblox they actually cover, and how long they survive contact with a motivated eleven-year-old.

Method Difficulty Blocks app Blocks browser Bypass difficulty for a determined kid Cost
Uninstall + standard (non-admin) account Easy Yes No Easy (just use the browser) Free
Hosts file edit Easy Yes Yes Easy (edit it back, or use a VPN) Free
Windows Firewall outbound rule Medium Yes No Medium (reinstall moves the .exe) Free
Microsoft Family Safety (Windows) Easy Yes Yes (Edge only) Medium (use Chrome, or a second account) Free
macOS Screen Time Easy Yes Yes (Safari best) Medium (guessing the passcode) Free
Router-level domain block Medium Yes Yes Medium (mobile hotspot, VPN) Free
DNS filtering (e.g. a filtering resolver) Medium Yes Yes Medium (change DNS, use a VPN) Free–low
Roblox's own parental controls Easy Limits only Limits only Medium (make a new account) Free
Allowlist parental control software Easy Yes Yes Hard Paid

The pattern: free methods block one route at a time, and each is undone in about the same amount of time it took to set up. That is not a reason to skip them. For a seven-year-old, a hosts file edit is genuinely enough. For a thirteen-year-old who has already searched "how to unblock a website", it is not.

How to Block Roblox on Windows 11

Windows 11 gives you two built-in routes. Use both together.

Remove the app and stop reinstalls:

  1. Settings > Apps > Installed apps
  2. Find Roblox (and Roblox Studio if present), click the three dots, choose Uninstall
  3. Settings > Accounts > Other users (or Family for a child account)
  4. Confirm your child's account type is Standard User, not Administrator. Click the account, Change account type, select Standard User

This matters more than anything else on this page. On a standard account, your child cannot install software, cannot edit the hosts file, and cannot change firewall rules. If your child uses an admin account, every method below is a suggestion rather than a control.

Add Microsoft Family Safety limits:

  1. Go to family.microsoft.com and sign in, or open the Family Safety app
  2. Select your child > Content filters > Web and search
  3. Turn on Filter inappropriate websites
  4. Under Blocked sites, add roblox.com and rbxcdn.com
  5. Under Apps and games, set an age limit or block Roblox specifically

The catch worth knowing up front: Family Safety's web filtering only enforces in Microsoft Edge, and it blocks other browsers to compensate. If your child needs Chrome for school, that trade-off falls apart. Our Microsoft Family Safety setup guide walks through the full configuration and its limits.

How to Block Roblox on Windows 10

The steps are nearly identical, with different menu names:

  1. Settings > Apps > Apps & features, select Roblox, Uninstall
  2. Settings > Accounts > Family & other users, select your child's account, Change account type > Standard User
  3. For web blocking, use the same Family Safety steps above — the online dashboard at family.microsoft.com is shared between Windows 10 and 11
  4. For a local block, use the hosts file method below, which behaves identically on both versions

Windows 10 reached end of support in October 2025, so it no longer receives feature updates to Family Safety. The hosts file and router methods are unaffected and remain the more reliable options on a Windows 10 machine.

How to Block Roblox on a Mac (macOS Screen Time)

macOS has the most capable built-in controls of any desktop OS, and they are free.

  1. System Settings > Screen Time (on macOS Monterey and earlier: System Preferences > Screen Time)
  2. Select your child's account from the dropdown at the top
  3. Click Content & Privacy and turn it on
  4. Under Content Restrictions > Web Content, choose Limit Adult Websites, then click Customise and add https://www.roblox.com under Restricted
  5. Under App Restrictions, uncheck Roblox, or set App Store to disallow installing apps
  6. Go back to Screen Time's main page and click Lock Screen Time Settings to set a four-digit passcode

Two things to get right. First, use a passcode your child has never seen you type — not your unlock PIN, not a birthday. Second, Screen Time's web restrictions are enforced most reliably in Safari; Chrome and Firefox handle them less consistently, so also delete other browsers or restrict them under App Restrictions. Our Mac parental controls guide covers the rest of Screen Time in detail.

Roblox Domains to Block (Copy-Paste List)

If you are blocking at the router, in a DNS filter, or in the hosts file, these are the domains that matter. Roblox is not a single domain — the game client, the web site, the asset delivery network and the login service all live on different hostnames, and missing one leaves a working route in.

The essential list — blocking these stops Roblox:

roblox.com
www.roblox.com
web.roblox.com
m.roblox.com
api.roblox.com
auth.roblox.com
users.roblox.com
games.roblox.com
apis.roblox.com
clientsettings.roblox.com
clientsettingscdn.roblox.com
setup.rbxcdn.com
assetdelivery.roblox.com
rbxcdn.com
roblox.qq.com

In hosts file format, add these lines to C:\Windows\System32\drivers\etc\hosts on Windows or /etc/hosts on Mac:

127.0.0.1 roblox.com
127.0.0.1 www.roblox.com
127.0.0.1 web.roblox.com
127.0.0.1 m.roblox.com
127.0.0.1 api.roblox.com
127.0.0.1 auth.roblox.com
127.0.0.1 users.roblox.com
127.0.0.1 games.roblox.com
127.0.0.1 apis.roblox.com
127.0.0.1 clientsettings.roblox.com
127.0.0.1 clientsettingscdn.roblox.com
127.0.0.1 setup.rbxcdn.com
127.0.0.1 assetdelivery.roblox.com
127.0.0.1 rbxcdn.com

On Windows, open Notepad as administrator first (Start > type Notepad > right-click > Run as administrator), open the hosts file with the file-type dropdown set to All Files, paste the lines at the bottom, save, then run ipconfig /flushdns in Command Prompt. On Mac, run sudo nano /etc/hosts, add the lines, save with Ctrl+O and Ctrl+X, then run sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder. The same technique applied to a different site is walked through step by step in our hosts file blocking guide.

Ports: Roblox's game client connects outbound over UDP ports 49152–65535 and uses TCP 443 for everything else. Blocking that UDP range at your router stops gameplay even if a domain slips through — but be careful, since that range is also used by video calls and other games. Blocking TCP 443 wholesale would block the entire web, so never do that; block by domain instead.

A warning about rbxcdn.com: this is Roblox's own content delivery network, so blocking it is safe for other services. But some routers match domains loosely — check that a broad wildcard is not catching unrelated sites.

How to Block Roblox at the Router (All Devices at Once)

A router block is the only free method that covers every device in the house at the same time — the PC, the laptop, the tablet, the console.

  1. Find your router's address (commonly 192.168.1.1 or 192.168.0.1) and open it in a browser
  2. Sign in with the admin password, usually printed on a sticker on the router
  3. Look for Parental Controls, Access Restrictions, URL Filtering or Content Filtering — the name varies by manufacturer
  4. Add the domains from the list above
  5. If your router supports per-device rules, apply the block only to your child's devices and schedule it by time of day

Two limitations to plan around. Router blocks do nothing on mobile data — a phone hotspot restores full access instantly. And many modern browsers use DNS-over-HTTPS, which can route domain lookups past router filtering entirely; you may need to disable secure DNS in the browser settings, or block DNS-over-HTTPS at the router if it offers that option.

How Kids Actually Bypass Each Method

Every parent who has blocked something has had the moment of finding it unblocked. Here is what actually happens, method by method, and what to do about it.

The browser instead of the app. By far the most common. Roblox runs fully at roblox.com with no install. Fix: always block the domains as well as the app. Blocking only the .exe is the single most common mistake.

Editing the hosts file back. It is a plain text file and a two-minute video explains it. Fix: a standard (non-admin) account makes the hosts file read-only to your child. This alone defeats the bypass.

A VPN or web proxy. Free VPN extensions install in one click and tunnel around hosts files, router blocks and DNS filters alike. Fix: on Windows, a standard account prevents installing VPN clients; browser extensions still install, so also block VPN and proxy sites by domain, or use software that filters by allowlist so unknown sites fail closed.

A mobile hotspot. A phone's hotspot bypasses every network-level control instantly. Fix: network controls cannot solve this — it needs a control that lives on the computer itself, plus a conversation about the phone.

A second account. A new Windows or Mac user account, or a new Roblox account created with a throwaway email, restores everything you configured on the first one. Fix: check for unfamiliar accounts on the login screen, and disable account creation where the OS allows it. Roblox account limits follow the account, not the computer.

Roblox Studio. Often overlooked. Studio is a separate install and can play experiences in test mode. Uninstall it alongside the player.

Changing the DNS server. If you filter through a DNS resolver, changing the network adapter's DNS in Windows settings undoes it in thirty seconds. Fix: a standard account blocks this too.

The through-line is that most bypasses only work from an administrator account. If you do one thing from this article, make it that. Our guide on how parental controls get bypassed covers the wider set of tricks.

Should You Block Roblox Entirely, Limit It, or Supervise It?

Blocking outright is right for some ages and counterproductive at others.

Under 8: blocking or a heavily restricted account makes sense. Chat with strangers is the main risk at this age, and children this young cannot reliably identify a grooming attempt. Roblox's own account controls for under-9s restrict chat by default — keep them on.

Ages 9–12: limiting usually beats blocking. Roblox is where friendships happen at this age, and a total block often just moves play to a friend's house where you have no visibility at all. Set a daily time limit, restrict chat to friends only, turn on a parental PIN and a monthly spend cap, and review the experiences they play.

13 and up: supervision over control. Teenagers can defeat most technical blocks given time, and a block imposed without explanation reliably produces a workaround. Keep spending limits and bedtime schedules — those are the two that hold up — and shift the rest to visible time reporting and a standing conversation.

A useful test: if you cannot explain to your child why a rule exists in one sentence, the rule will not survive. "No chat with people you haven't met" is explainable. "No Roblox" often is not, and that is why it gets bypassed.

Roblox's Own Parental Controls (Free, and Worth Setting Up)

If you are limiting rather than blocking, Roblox's built-in controls are genuinely useful and take about five minutes.

  1. Sign in to your child's account at roblox.com
  2. Go to Settings > Parental Controls and add your parent email, then enable a Parent PIN
  3. Set Content Maturity to an age-appropriate level (Minimal, Mild, Moderate or Restricted)
  4. Under Settings > Privacy, set Contact Settings — who can message, chat in-app and in-experience, and follow. "Friends" or "No one" are the safe choices
  5. Under Parental Controls, set a Monthly Spend Restriction to cap Robux purchases
  6. Turn on Screen Time limits and daily reports if available on the account

These rely on Roblox's own content ratings and moderation, which is not perfect at the scale it operates. But spend limits and contact settings are enforced server-side, which means they follow the account to any device — something no PC-side block can do. If Roblox has already become the bigger issue, our post on what to do when a kid is addicted to Roblox covers the behavioural side.

Blocking the App Without Blocking the Web (Windows Firewall)

If you want Roblox installed but unable to connect — useful when a shared family PC has other users — a firewall rule does it quietly, with no error message that reveals what changed.

  1. Open Windows Security > Firewall & network protection > Advanced settings
  2. Click Outbound Rules > New Rule
  3. Choose Program, then browse to C:\Users\[username]\AppData\Local\Roblox\Versions\[version]\RobloxPlayerBeta.exe
  4. Choose Block the connection
  5. Apply to Domain, Private and Public
  6. Name it "Block Roblox"

The maintenance cost is real: Roblox updates often, and each update creates a new Versions\ folder with a new path, which silently invalidates your rule. Plan to recheck it, and pair it with a domain block since the firewall rule does nothing to the browser version.

When a Free Method Is Enough — and When It Isn't

Be honest about which situation you are in.

A free method is enough if your child is young, uses one computer, has a standard account, and is not actively trying to get around you. A hosts file edit plus a non-admin account genuinely solves that. Don't spend money on it.

You need something stronger if you have already been bypassed once, if you are managing several devices, or if you want the middle ground — some Roblox, at set times — rather than all-or-nothing. Blocklists are also structurally on the back foot: you have to name every domain in advance, and a new mirror or proxy site defeats them.

That structural problem is why 3Eyes works the other way around: it is allowlist-first, so only sites you approve load and everything else — including Roblox mirrors and proxy sites you have never heard of — shows an "Ask Parent" page by default. It runs as a managed app on Windows and Mac that resists the edit-the-file and sign-out tricks, adds daily time limits and scheduled downtime, and lets you approve a request from your phone when your child asks for something. It is paid software, with a 14-day trial. If a hosts file is holding fine in your house, you do not need it.

Frequently Asked Questions

How do I block Roblox on a laptop? Exactly as described for a desktop PC — the steps are identical on an HP, Dell, Lenovo or Acer laptop because they are Windows settings, not hardware settings. Uninstall the app, set a standard account, and block the domains.

Can I block Roblox but allow other games? Yes. The domain and firewall methods target Roblox specifically and leave Steam, Minecraft and everything else untouched. Only a whole-computer time limit affects all games at once. See our Steam parental controls guide for the equivalent on Steam.

Why can my child still play Roblox after I blocked it? Almost always one of three things: they are using the browser version at roblox.com rather than the app, they are on an administrator account and undid the change, or they are on a phone hotspot rather than your Wi-Fi. Check the account type first.

Does blocking rbxcdn.com break anything else? No. It is Roblox's own content delivery network and is not shared with unrelated services. Blocking it stops Roblox assets from loading, which is the point.

Is there a difference between blocking and banning Roblox? No — parents use both words for the same thing. If you want to ban Roblox on a PC, the thing that matters is whether you ban the app, the website, or both. The app and roblox.com are separate routes in, so blocking one leaves the other working.

Can I block the Roblox website but leave the app installed? Yes. Blocking the domains stops roblox.com in every browser while the installed app keeps its shortcut, though it will fail to connect. To do the reverse — allow the website and block only the app — use the Windows Firewall rule below instead of the domain list.

How do I unblock Roblox again? Reverse whatever you did: delete the hosts file lines and flush DNS, delete the firewall rule from Outbound Rules, or remove the domains from your router's blocklist. All are reversible in under a minute.

Can Roblox be blocked on a school Chromebook? School-managed Chromebooks are usually already filtered by the school's admin console, and parents cannot override that. On a family-owned Chromebook you can block it with Family Link or with parental control software — see our Chromebook parental controls guide.

Start with the standard account. Then block the domains. Everything else is a refinement on those two.
