Which one is for you

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

Pick Vivaldi if

  • Fits if you keep dozens of tabs open and want them stacked, split and sorted
  • Works for people who want mail, calendar and feeds in the same window as their tabs

Look elsewhere if

  • Skip it if you want a chatbot or page summaries built in, because Vivaldi leaves AI out on purpose
  • Not for you if you want the free VPN on your phone, as it only works in the desktop browser
  • Pricey if you want faster VPN speeds, more servers or extra devices, which need a paid Proton VPN plan
  • Watch out: new installs come with partner bookmarks and search engines that earn Vivaldi revenue until you replace them
  • Not for you if your Mac is older than macOS 13, which the current download needs

How we grade them

2.8GPAIridium BrowserGood3.8GPAVivaldiExcellent
Value for money
AFree to use, with no paid plans listed, so under 60% of this category's cheapest quarter.
AFree on every platform with no paid tier at all, and the reason is on Vivaldi's own blog: it earns from search and bookmark partner deals, a cut of Proton VPN upgrades and donations, rather than from you. There's nothing to buy and nothing withheld.
Free plan and trial
AThe whole browser is free, including an MSI package and a portable Windows zip, with no cap to reach.
AFree outright, with mail, calendar, feed reader, notes, the ad and tracker blocker, end-to-end encrypted sync, and Proton VPN on the desktop with no ads or data limit. New installs arrive with partner bookmarks you can swap out.
Features
CIt keeps the Chromium interface and extension model, but it lacks Google sign-in and Chrome sync because it ships without Google API keys.
AIt builds in an email client for several accounts, a calendar, a feed reader and notes, with an ad blocker, two-level Tab Stacks, tiling, Workspaces and Command Chains that fire a string of commands off one keystroke. The deliberate gap is AI: there's none, by choice.
Ease of use
CNo rating on record. Updates mean downloading and installing the latest build by hand, which is more upkeep than a normal browser.
A4.73 from about 4,400 App Store ratings. You can leave it exactly as it comes, or change shortcuts, themes and layout until it fits. There's a lot in here, so give it an evening.
Platforms and integrations
CWindows, macOS and Linux only. The download page lists no Android or iOS version.
BWindows, Mac, Linux, Android and iPhone, with history, passwords, bookmarks, tabs and notes synced end-to-end encrypted. Computers and both phones is a B here, because our top mark also wants a web app and a browser isn't one, and Proton VPN is the only integration listed.

Worth knowing

Iridium Browser

  • Iridium does not update itself: updates mean downloading and installing the latest build manually.
  • Signing in to Google and Chrome sync does not work, because the browser ships without Google API keys.
  • Google Safe Browsing is on by default and contacts iridiumbrowser.de and Google's servers unless you turn it off.
  • Not available for Android, iOS or other mobile systems. The download page lists only source code tarballs, and the FAQ describes Windows, macOS and Linux installs.

Vivaldi

  • Proton VPN for Vivaldi works only in the desktop browser, and faster speeds, more servers and extra devices need a paid Proton VPN plan.
  • New installs come with partner bookmarks and search engines that earn Vivaldi revenue. They can be replaced.
  • Vivaldi deliberately leaves out an AI assistant, so there is no built-in chatbot or page summarizer.
  • The current Mac download requires macOS 13 or later.

Key features

Iridium Browser

Chromium base
Built from the Chromium code base, so it keeps the Chromium interface and extension model while changing privacy-related defaults.
Privacy defaults
Automatic transmission of partial queries, keywords and metrics to central services is blocked and only happens with the user's approval.
Reproducible builds
The project says all of its builds are reproducible and that its changes can be audited in a public Git repository.
MSI deployment
The Windows installer is an MSI package, which the site presents as a way for administrators to roll the browser out across an organization.
Portable Windows version
A zip-file portable edition runs without installing and can keep its data in a folder of your choice.

Vivaldi

Mail, Calendar and Feed Reader
A built-in email client handles several accounts, mailing lists and feeds in one inbox, next to a private calendar and a feed reader that does not rank items by algorithm.
Tab Stacks, tiling and Workspaces
Tabs group into two-level Tab Stacks, open side by side in a split-screen view, and sort into Workspaces for switching between categories of tabs.
Ad and tracker blocker
A blocker for ads and trackers is built into the desktop and mobile browsers, so no extension is needed to remove them.
End-to-end encrypted Sync
Browsing history, passwords, bookmarks, tabs and notes sync between desktop and mobile devices, protected by end-to-end encryption.
Proton VPN for Vivaldi
An opt-in VPN from Proton is built into the desktop browser. It is free with no ads or data limits after signing in with a Vivaldi account.
Customization and Command Chains
Shortcuts, themes and features can be personalized, mouse gestures trigger actions, and Command Chains run a custom sequence of commands from one keystroke or gesture.

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.
