Tor Browser Alpha
Tor Browser Alpha is a prerelease web browser for testing privacy and anti-censorship features on the Tor network before stable releases.
What is Tor Browser Alpha?
Tor Browser Alpha is the prerelease testing version of Tor Browser for people who want early access to upcoming browser changes and who are comfortable trying software that may be less polished than the stable release. It helps users browse the web through the Tor network to reduce tracking, limit fingerprinting, and work around some forms of censorship. On macOS, it functions as a desktop web browser with the same general privacy-focused purpose as Tor Browser Stable, but the Alpha channel is intended for testing and feedback rather than dependable day-to-day use. It is useful for developers, testers, researchers, and experienced users who want to preview new features, interface changes, and security-related updates before they reach the main release channel. Because it is an alpha build, users should expect a higher chance of bugs or behavior changes between releases.

Safety overview
Status: Use with caution
Tor Browser Alpha is legitimate software from The Tor Project, but this release channel is meant for testing and can contain bugs that affect reliability, privacy, or security behavior. Network activity through Tor is normal for its purpose, and slower browsing speeds are also expected. Use it when you specifically want to test upcoming changes, and prefer the stable Tor Browser release for routine browsing or situations where dependable privacy protection matters most.
Recommendation: Keep Tor Browser Alpha if you actively test prerelease builds or need to preview changes before they reach the stable channel. If you just want private everyday browsing, switch to the stable Tor Browser release and remove the Alpha version when you no longer need it.
