What is Tor Browser?
Tor Browser is a web browser built to hide both what you read and where you are reading it from. Traffic is relayed and encrypted three times across the Tor network, a set of thousands of volunteer-run relays, so anyone watching the connection can see only that Tor is in use, not which sites are visited. The browser isolates each site from the others, clears cookies and history when a session ends, and deliberately makes every user look alike to resist fingerprinting. It is free and open source, and it can reach sites a local network blocks. It suits people who need anonymity or censorship circumvention and accept that browsing will be slower.

Key features
What Tor Browser does at a glance.
Traffic is relayed and encrypted three times across the Tor network
Each website is isolated so third-party trackers and ads cannot follow you between sites
Cookies and browsing history are cleared when a session ends
Resists browser fingerprinting
By making users look alike
Reaches sites
A local network or ISP has blocked
Runs on the Tor network of thousands of volunteer-run relays
What you can use Tor Browser for
- Browsing without revealing which sites you visit to your network or ISP
- Reaching a site that is blocked on the local network
- Researching sensitive topics without leaving a durable local trail
Who is Tor Browser for?
- Journalists, researchers and activists who need anonymity or censorship circumvention
- Anyone who wants their browsing separated from their identity, and accepts the speed cost
Who is Tor Browser not for?
- People who want everyday browsing speed — routing through three relays is inherently slower
- Users who need to sign into accounts tied to their real identity, which defeats the anonymity the network provides
Limitations
- Browsing is noticeably slower than a direct connection because traffic passes through three relays
- Some sites block Tor traffic outright, and some features of ordinary browsers are restricted to reduce fingerprinting
- Nuanyue has not established which macOS versions the current release requires
- Apple Silicon support is not stated in the sources Nuanyue tracks
Strengths and trade-offs
What Tor Browser does well, and what to weigh before choosing it. Points marked developer-stated come from the developer’s own material and have not been independently confirmed.
Strengths
- Traffic is relayed and encrypted three times as it crosses the Tor network.Developer-stated
- Isolates each website and clears cookies and history, so trackers cannot follow a user between sites.Developer-stated
- Actively resists fingerprinting by making users look alike rather than by asking them to configure settings.Developer-stated
- Can reach sites that the local network has blocked.Developer-stated
Trade-offs
- Routing through three relays makes browsing slower than a direct connection.Derived
- Some websites refuse Tor traffic, so parts of the web are unreachable through it.Editorially reviewed
- The anonymity depends on not signing into accounts that identify the user, which limits its use for everyday logins.Editorially reviewed

What it does
Tor Browser does two things at once. Locally it behaves like a privacy-hardened browser: each website is isolated from the others, cookies and history are discarded when a session ends, and the browser works to make every user look the same so that fingerprinting cannot single anyone out. On the network side it routes traffic through the Tor network, where it is relayed and encrypted three times across thousands of volunteer-run relays.
What that hides
The result is that someone watching the connection can see that Tor is in use, but not which sites are being visited — and a site that receives the request does not learn the visitor’s address. The same routing is what lets Tor Browser reach pages a local network or ISP has blocked.
The cost
Anonymity is not free. Three relays add latency, so browsing is slower than a direct connection, and some sites block Tor traffic outright. Signing into an account that carries a real identity also undoes much of what the network provides, which is why Tor Browser is a tool for specific situations rather than a default browser.
Questions about Tor Browser
Is Tor Browser free?
Yes. Tor Browser is free and open source, developed by the non-profit Tor Project.
How does Tor Browser hide which sites I visit?
Traffic is relayed and encrypted three times as it passes over the Tor network, which is made up of thousands of volunteer-run relays. Anyone monitoring the connection can see only that Tor is being used.Developer-stated
Does Tor Browser stop trackers?
Yes. It isolates each website so third-party trackers and ads cannot follow you between sites, and cookies and browsing history are cleared when you finish.Developer-stated
Why is Tor Browser slower than other browsers?
Because traffic is routed through three relays in the Tor network before reaching a site, which adds latency compared with a direct connection.Derived
Alternatives to Tor Browser
Apps that could replace this one — the same job, a different trade-off.
Firefox
Mozilla's open-source browser with its own engine.
Both are free, open-source browsers, but Firefox browses the web directly while Tor Browser routes everything through the Tor network for anonymity.
Similar apps
Related in purpose, but not a straight swap.
Brave
Privacy-first Chromium browser with ad and tracker blocking built in.
Both aim to reduce tracking while browsing, but Brave blocks trackers locally while Tor Browser also hides the user's location by relaying traffic through Tor.
