UC Browser

UC Browser is one of the most used browsers you may never have opened. Owned by Alibaba since 2014, it holds around 1% of global browsing and roughly 600 million monthly users, over half of them in India and Indonesia. Its appeal is concrete: a small app, aggressive data compression through cloud acceleration, and a download manager that splits files into parts to pull them down faster — features that matter enormously on slow or metered connections and barely register on fast ones.

The privacy record is the reason it sits at the bottom of our ratings. Citizen Lab documented security and privacy failures across multiple investigations, and reporting by Forbes in 2021 found the browser sending every visited page to UCWeb servers regardless of whether the user was in incognito mode, along with IP addresses going to Alibaba-controlled infrastructure. India banned it outright over data and national security concerns. These are documented findings about behaviour, not speculation about ownership.

It is also narrower than it once was. The Android app is actively updated, but the Windows build has not moved since 2023, which is why we list this as an Android browser — a three-year-old Chromium is not a platform we would point anyone at. If you are on a slow connection and need the compression and download handling, nothing here works better. For anyone else, Opera Mini offers similar data saving with a far less troubled history.
