The internet, minus the worst of it.
CleanBrowse blocks adult sites across your whole Mac, blurs explicit images in Safari before you see them, and strips out ads and trackers — all from one menu bar icon. Free, private, and on-device.

Everything in one free app
Four protections. One menu bar icon.
Each one works on its own. Together, they cover the whole web — every browser, every app, every image.
Explicit image blur
On-device AI checks every image and video in Safari and blurs anything explicit before it appears.
Learn moreAdult-site blocking
249,000+ adult domains blocked in every browser and app — now on the DNS provider you choose.
Learn moreAd & tracker blocking
Cleaner, faster pages in Safari. Ads, trackers, pop-unders and scam pages stopped before they load.
Learn moreWork-site mode
Pause blur on the tools you work in — GitHub, Figma, Zoom — while every other site stays protected.
Learn moreSafari image blur
Explicit images, blurred before you see them.
Blocking sites isn't enough — explicit images hide on pages you actually use. The new Safari extension classifies every image and video frame with on-device machine learning, and blurs anything explicit before it's rendered.
Blur first, reveal later
Every image starts blurred and is only revealed once the model clears it. Video frames are checked while they play, so explicit scenes are caught mid-stream.
Everywhere Safari goes
Google Images, social media feeds, streaming platforms like Netflix — if Safari can show it, the filter has already checked it.
Private by design
Classification runs entirely on your Mac with Core ML. No image, no URL, no pixel ever leaves your machine — and anything that can't be checked stays blurred.
Adult-site blocking
Adult sites never load. In any browser, in any app.
CleanBrowse filters every DNS query on your Mac. Adult domains never resolve, search engines are locked to SafeSearch, and everything else passes through untouched — with no measurable slowdown.
- Adult content→NXDOMAIN
- Search engines→SafeSearch endpoints
- Everything else→resolves normally
Simulated DNS query log: adult domains resolve to NXDOMAIN, search engines are rewritten to their SafeSearch endpoints, and everything else resolves normally.
New in 2.0 — DNS provider
Bring the DNS you trust.
Pick from 13 resolvers: family filters that add a second layer of adult-content blocking, DNS that blocks ads and malware, or a fast unfiltered resolver. CleanBrowse's blocklist always answers first — your provider handles everything else.

New in 2.0 — Safari ad blocker
The web, without the clutter.
CleanBrowse now blocks ads and trackers in Safari, using the filter lists trusted by millions — EasyList, EasyPrivacy, and uBlock Origin. Pages load faster, read cleaner, and stop following you around.
Ads gone, layout intact
Ad and tracker requests are stopped before they load, and the empty boxes they leave behind are tidied away.
120,000+ rules, all on your Mac
Safari applies every rule itself. Nothing about the pages you visit is sent anywhere — not to us, not to anyone.
On by default, one switch away
Turn ad blocking off and on from the toolbar popup whenever you need to.
New in 2.0 — Work-site mode
Sharp images at work. Protected everywhere else.
Design files, code reviews and video calls are full of images that never need checking. Work-site mode lets the blur step aside on the tools you work in — and keeps every other site fully protected.
Your work tools, ready to go
GitHub, GitLab, Figma, Linear, Notion, Zoom, Slack, Google Docs and more are on the list from day one.
Make the list yours
Add or remove sites right from the popup. Each site covers its subdomains too.
Off until you turn it on
Work-site mode starts switched off, and sites where anyone can post images — like Google Images or Drive — are never on the list.
How it works
Four layers. No way around them.
Browser extensions can be uninstalled and settings can be reset. CleanBrowse works below all of that — at the system level — so the protection holds everywhere. And in Safari, a fourth layer catches what a blocklist never could.
Hosts file blocking
Over 249,000 known adult domains are redirected to localhost through the system hosts file — the first wall, and it covers every application on your Mac.
System-wide DNS proxy
A local DNS proxy inspects every query type — including encrypted DNS — and answers NXDOMAIN for anything on the blocklist. What can't resolve can't load.
Enforced SafeSearch
Google, YouTube, Bing, and DuckDuckGo are pinned to their SafeSearch endpoints at the IP level, across 190+ country domains. Search results stay clean too.
On-device image blur
A Safari extension classifies every image and video frame with on-device machine learning and blurs explicit content before it's rendered — even on sites no blocklist would ever block.
From the maker
“Everyone should have the tools to protect themselves and their loved ones online — without a subscription, and without handing their data to anyone.”
CleanBrowse is built and maintained by one person, and it's completely free. No accounts, no tracking of your browsing — what you do online never leaves your Mac.
Privacy
We count clicks, not people.
Your browsing never leaves your Mac — every site you visit, every DNS query, every blocked domain stays on your machine. The only thing CleanBrowse shares is an anonymous tally of feature usage through Aptabase, a privacy-first, open-source analytics service. It tells the maker which features matter — and nothing about who you are.
How Aptabase handles dataStays on your Mac
