The Tor software protects you by bouncing your communications around a distributed network of relays run by volunteers all around the world: it prevents somebody watching your Internet connection from learning what sites you visit, it prevents the sites you visit from learning your physical location, and it lets you access sites which are blocked. The Tor Browser lets you use Tor on Windows, Mac OS X, or Linux without needing to install any software.
- Tor Browser is only browser a which works through the Tor network, but TunnelBear is full system-wide VPN.
- Open source versus closed source. Two totally different VPN approaches that cannot be compared.
