Vivaldi gives power users tab stacks, a built-in mail client, web panels, and notes in one window. The trade-offs are real: cold-start times trail Chrome by a noticeable margin on Windows, sync still drops bookmark folders on some setups, and the proprietary code on top of Chromium puts it behind on the fully open-source side. We tested seven Vivaldi alternatives for desktop in 2026 and ranked them by how much of the workflow they preserve.

Why people leave Vivaldi
Startup and memory. Vivaldi launches noticeably slower than Chrome or Edge on the same machine. Heavy users with 200+ open tabs report multi-second waits on cold start, even with hibernation enabled.
Sync hiccups. Vivaldi Sync is end-to-end encrypted, which is great, but the trade-off shows up as occasional bookmark folder drops and slow propagation between machines. People who depend on real-time sync across two or three devices end up turning to Firefox Sync or Brave Sync instead.
Closed-source UI. Vivaldi’s interface is proprietary. The Chromium engine is open, but the layer that makes Vivaldi feel like Vivaldi is not. That matters to readers who want full audit-ability.
Mail client maturity. Vivaldi Mail is useful and free, but it lags Thunderbird on filtering, search, and large-account handling. People who actually run their email from the browser eventually move to a dedicated client.
The alternatives
Firefox — best for open-source defaults
Firefox is the only mainstream non-Chromium engine left. That alone makes it worth installing as a second browser, even if Vivaldi stays as the primary. Container tabs let you separate work, personal, and shopping identities cleanly, and uBlock Origin still works at full strength because Firefox kept Manifest V2 support alongside V3.
Where it falls short: No tab stacks. Vertical tabs landed recently but are less mature than what Vivaldi or Edge ship. Some power users miss Vivaldi’s command palette.
Pricing: Free, open source. Mozilla VPN runs separately starting around $5/month if you want it.
Migrating from Vivaldi: Firefox imports bookmarks, passwords, and history through the standard import dialog. Tab stacks do not transfer. Sync is set up separately through a Mozilla account.
Download: Firefox for desktop
Bottom line: The right pick if you want full open source, real ad blocking, and a non-Chromium engine. Skip it if your daily workflow leans on Vivaldi’s tab stacks.
Brave — best for privacy without leaving Chromium
Brave runs the same site compatibility as Chrome (Chromium engine, V8) but ships Shields by default, blocks third-party trackers, and adds a Tor window for sensitive browsing. Vertical tabs are built in. The optional Brave Search engine integrates cleanly.
Where it falls short: Crypto wallet and Rewards are bundled. Both can be disabled, but they ship enabled and the wallet has caused confusion for people who never asked for it.
Pricing: Free. Brave Talk Premium runs about $7/month for hosted video calls; ignore it if you don’t need the feature.
Migrating from Vivaldi: Bookmarks, passwords, autofill, and history import cleanly via the import dialog. Tab stacks become tab groups (built into Chromium) which are flat, not nested.
Download: Brave for desktop
Bottom line: The Chromium browser to use if you want Vivaldi-style controls minus the proprietary layer. The crypto integration is the only friction.
Arc — best for a fresh take on the window
Arc replaces the tab bar with a sidebar, groups tabs into Spaces, and adds a command bar that doubles as a search box. The Little Arc popup is genuinely useful for one-off links you don’t want polluting your main window.
Where it falls short: Windows support is newer and feels less polished than the Mac build. The Browser Company has been shifting focus toward Dia, the AI-first sibling, which raises questions about Arc’s long-term roadmap.
Pricing: Free. No paid tier currently.
Migrating from Vivaldi: Bookmarks and passwords import. Spaces are different enough from tab stacks that you’ll rebuild your tab organization rather than translate it directly.
Download: Arc for desktop
Bottom line: Try Arc if you want to rethink how tabs work. Stay on Vivaldi if you need the mail client or the panels.
Opera — best for built-in extras
Opera matches Vivaldi for built-in features: a sidebar of messengers, workspaces that act like tab spaces, and a free VPN with no signup. The browser is Chromium-based, so site compatibility is on par with Chrome.
Where it falls short: Opera’s VPN is a browser-only proxy, not a real system VPN, and the Aria sidebar AI is hard to remove. Ownership changes over the years have left some users wary.
Pricing: Free. Opera GX is the same browser tuned for gamers; Opera One Pro adds advanced AI features for around $9.99/month.
Migrating from Vivaldi: Standard Chromium import for bookmarks and passwords. Workspaces map to Vivaldi workspaces reasonably well.
Download: Opera for desktop
Bottom line: The closest match to Vivaldi’s “everything in the sidebar” philosophy. Drops the mail client.
Microsoft Edge — best for vertical tabs with a light footprint
Microsoft Edge is the Chromium browser that ships with Windows. It includes vertical tabs, sleeping tabs (which reduce memory on inactive tabs), Collections for bookmark grouping, and tight OS integration on Windows.
Where it falls short: Bing, Copilot, and Microsoft Rewards are pushed hard. Each can be turned off, but the defaults skew aggressively toward Microsoft’s services.
Pricing: Free.
Migrating from Vivaldi: Import through the standard dialog. Tab stacks become tab groups.
Download: Microsoft Edge for desktop
Bottom line: The right pick if you live in Windows and want a Chromium browser with light per-tab memory use. Skip it if Microsoft account prompts and Bing irritate you.
Zen Browser — best for a Firefox-based Arc
Zen Browser is built on Firefox’s engine and copies the parts of Arc that worked: workspaces, a clean sidebar, a compact mode, and a “Glance” feature for previewing links. Because it’s Firefox underneath, uBlock Origin runs at full strength.
Where it falls short: Younger project. Sync goes through Firefox Sync, which works but lacks Vivaldi’s tab-stack preservation. Some keyboard shortcuts still feel under-developed.
Pricing: Free, open source.
Migrating from Vivaldi: Bookmarks and passwords import. Workspaces are conceptually similar to Vivaldi workspaces and will feel familiar.
Download: Zen Browser for desktop
Bottom line: The browser to watch if you like Arc’s ideas but want Firefox’s engine and openness.
LibreWolf — best for telemetry-free Firefox
LibreWolf is Firefox with telemetry stripped, tracking protection cranked up, and a few privacy defaults flipped. uBlock Origin ships preinstalled. It’s the cleanest option for people who want Firefox without any phoning home.
Where it falls short: No tab stacks, no mail client, no command palette. This is a privacy tool first and a power-user tool second. Sync requires a separate Firefox account, which contradicts the no-telemetry stance for some users.
Pricing: Free, open source.
Migrating from Vivaldi: Bookmarks and passwords import through the standard Firefox dialog. Nothing else carries over.
Download: LibreWolf for desktop
Bottom line: Pick this if telemetry is what drove you away from Chrome and what worries you about Vivaldi’s proprietary UI layer.
How to choose
- Pick Firefox if you want a fully open-source engine, real ad blocking, and container tabs to separate identities.
- Pick Brave if you want a Chromium browser that handles tracking and ads out of the box.
- Pick Arc if you want to rethink how tabs and windows work on macOS.
- Pick Opera if you want a sidebar of messengers and a browser VPN without paying.
- Pick Microsoft Edge if you’re on Windows and want vertical tabs with minimal RAM use.
- Pick Zen Browser if you want Arc-style workspaces on the Firefox engine.
- Pick LibreWolf if no telemetry is a hard requirement.
- Stay on Vivaldi if tab stacks, the mail client, or the notes panel are part of your daily workflow. None of the alternatives match all three.
FAQ
Is Vivaldi safer than Chrome? Vivaldi blocks more trackers by default and sends less telemetry than Chrome. It’s not open source, so audit-ability is lower, but day-to-day privacy is better.
Why is Vivaldi so slow to start? The browser preloads its tab stack system, mail client, and panels on launch, which adds startup time. Disabling features you don’t use (mail, calendar) helps.
Can I import my Vivaldi data into Firefox? Yes. Firefox’s import dialog reads Vivaldi’s bookmarks, passwords, and history directly. Tab stacks do not transfer.
Is Brave or Vivaldi better for privacy? Brave blocks more by default, including trackers and ads, and offers Tor windows. Vivaldi is more configurable but ships fewer blocks out of the box.
Which Vivaldi alternative uses the least RAM? Edge’s sleeping tabs and Brave’s tab discarding both significantly reduce memory for inactive tabs. Firefox on default settings sits between the two.
Is there an open-source browser with tab stacks? Zen Browser comes closest, with workspaces and split view on Firefox’s engine. Pure tab stacks like Vivaldi’s are still unique.
