Experience & key features

What Cốc Cốc is

Cốc Cốc is a Chromium-based browser from Cốc Cốc Company Limited in Hanoi. Per Wikipedia, the first official release came on 14 May 2013 under the name Cờ Rôm+, and it was renamed Cốc Cốc on 2 April 2014. The download page offers official builds for Windows, macOS, Android and iOS and a test build for Linux, plus beta channels for Windows and Android.

Key features

According to the homepage, Cốc Cốc blocks intrusive ads such as popups, redirects and ads that interrupt videos; downloads video and music from most sites, including YouTube, Facebook and TikTok, without extra software; and translates highlighted text into 100+ languages in a sidebar. Wikipedia also mentions an English–Vietnamese dictionary that shows meaning and pronunciation when you double-click an English word. Per the App Store, the iOS app adds Pin Video, background audio, Cinema Mode, Browser Lock and sync of bookmarks, passwords and history across devices.

Price, ads and data

The browser is free, but the Google Play listing says the Android app contains ads and in-app purchases. The browser policy says Cốc Cốc collects anonymous information to improve its products and explains how to disable sending it, but the details could not be read. The App Store privacy label says usage data is used to track users. Privacy-minded users should review the settings and the original policy themselves.

More analysis

Market position

Per Wikipedia, Cốc Cốc peaked at 32.54% desktop share in August 2017 and had over 22 million users in October 2017, second only to Chrome. StatCounter for October 2026 shows Cốc Cốc at 4.62% across all platforms in Vietnam, behind Chrome (68.68%) and Safari (19.57%).

Compared with alternatives

Cốc Cốc is worth considering if you want built-in video download and ad blocking. Chrome and Edge have larger sync ecosystems and AI assistants without in-app ads, while Firefox or Brave are commonly chosen when privacy comes first.

A familiar Chromium base with download and translation tools built in, so no extensions need to be found and installed.
