Which one is for you
Pick Chromium if
- Fits if you build or study the browser source
- Makes sense if you need one specific build to check a bug fix
Look elsewhere if
- Skip it if you want a browser that updates itself, since Chromium builds do not
- Not for you if you want a build that matches a Chrome release, as snapshots come from arbitrary revisions
- Watch out: the download page offers no Android or iOS installer
- Too light for everyday use: the site says Chrome builds suit most users
Pick Iridium Browser if
- Fits if you want a Chromium browser that holds back partial queries and metrics by default
- Makes sense if you roll out browsers to staff, since Windows comes as an MSI
Look elsewhere if
- Skip it if you want Chrome sync or Google sign-in, because neither works
- Not for you if you want automatic updates: you download each new build yourself
- Watch out: Google Safe Browsing is on by default and contacts iridiumbrowser.de and Google's servers
- Too light for phones: there is no Android or iOS version

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
