What Onion Browser is

Onion Browser is a free, open-source browser for iOS that routes browsing inside the app through the Tor network. It can open .onion sites, block scripts, and automatically clear cookies and tabs according to user preferences. Users can set security options for individual websites; HTML5 geolocation features may be available unless Strict security mode is enabled. The privacy policy says Onion Browser does not directly collect user activity data and does not use third-party analytics beyond what iOS includes. Its protection is limited to traffic within the browser: other device traffic continues over the normal connection, and iOS may route some content, including audio or video embeds, outside Tor. Apple requires iOS browsers to use WebKit, so the app cannot include its own Firefox Gecko engine. The App Store listing says browsing is much slower than a normal browser or VPN because Tor traffic is encrypted and relayed. Some networks with advanced restrictions may prevent it from connecting; the listing suggests trying bridges if that happens. Onion Browser is made by Onion Browser, founded in 2012, and is listed as free.

Good

  • Routes in-app browsing through Tor.
  • Can access .onion sites.
  • Can block scripts and clear cookies and tabs.
  • Open-source and free to use.

Watch out

  • Only traffic within the app is tunneled.
  • Some traffic may go outside Tor.
  • Browsing is much slower than a normal browser or VPN.
  • Restricted networks may prevent connection.

Who it suits

It suits iOS users who want Tor access, .onion site support, and controls for scripts, cookies, tabs, and site security. It is not a device-wide traffic tunnel, so it may not suit someone seeking to route all device traffic through Tor.

Verdict

Onion Browser offers Tor routing and .onion access within an iOS browser, with configurable security and clearing controls. Its app-only traffic scope, possible routing leaks, and slower browsing are important considerations.
