Opera vs Vivaldi: Which Browser Fits You?

Opera and Vivaldi are two Chromium-based browsers that share a common ancestor but now target very different users. Opera is a polished, feature-packed browser for mainstream users who want convenience and built-in extras, while Vivaldi is a highly customizable tool for power users who want to control every aspect of their browsing experience. This article breaks down their histories, features, performance, and privacy so you can decide which one matches your workflow.

Background: From the Same Roots

Both browsers trace their lineage to the original Opera browser, which was first released in 1995 and developed by Opera Software. Opera was known for innovation—it introduced features like tabbed browsing, mouse gestures, and a built-in ad blocker long before they became standard. In 2013, Opera made a major shift by abandoning its own Presto engine in favor of Chromium, the open-source project that also powers Google Chrome. This move allowed Opera to focus on adding unique features rather than maintaining a rendering engine.

Vivaldi was created in 2015 by Jon von Tetzchner, one of Opera’s co-founders, who left the company after the Chromium switch. He wanted to build a browser for the power users who felt Opera had lost its way. Vivaldi is built on Chromium too, but it emphasizes deep customization and advanced tab management, aiming to recreate the flexibility that early Opera fans loved.

Today, both browsers are free and available on Windows, macOS, and Linux. They share the same underlying engine, so most websites render identically, but their user interfaces and built-in tools differ significantly.

Interface and Customization

The most obvious difference is how each browser looks and feels out of the box. Opera presents a clean, modern interface with a sidebar that includes shortcuts to social media, messaging apps, and a built-in music player. It’s designed to be intuitive for casual users, with a focus on quick access to popular services.

Vivaldi, on the other hand, is a blank canvas. You can move the tab bar to any edge of the screen, change its position, and even stack tabs in groups. The browser lets you customize keyboard shortcuts, mouse gestures, and create custom commands. You can also adjust the color scheme and choose between light and dark themes. For users who like to tweak every detail, Vivaldi offers more flexibility than almost any other browser.

Built-in Features

Opera packs a lot of functionality right out of the box. Its standout features include:

• Built-in ad blocker that blocks ads and trackers by default.
• Free VPN (with a data limit) that can hide your IP address.
• Flow – a feature that lets you send links and notes between your devices.
• Video pop-out – a floating mini-player for videos.
• Snapchat, WhatsApp, and Instagram integration in the sidebar.

Vivaldi also includes a built-in ad blocker, but its focus is on productivity tools:

• Tab stacking – group tabs by dragging one onto another.
• Tab tiling – view multiple tabs side by side.
• Web panels – keep a website open in a small panel for quick reference.
• Notes – take notes while browsing and attach them to pages.
• Command palette – search and execute commands without using the mouse.

Performance and Resource Usage

Because both use Chromium, they have similar rendering speeds and JavaScript performance. However, they differ in memory usage. Opera is generally lighter on RAM, making it a good choice for older computers or systems with limited memory. Vivaldi, with its many features and customizable interface, tends to use more memory, especially if you have many tabs open or use web panels.

In practice, the difference is noticeable only on very low-spec machines. On a modern PC with 8GB or more RAM, both browsers feel snappy. If you’re a heavy tab user, Vivaldi’s tab management can actually help you keep memory usage in check by letting you hibernate inactive tabs.

Privacy and Security

Both browsers are built on Chromium, so they share the same security patches and sandboxing. However, their privacy features differ. Opera includes a free VPN, but it’s important to note that this VPN only encrypts traffic within the browser, not all system traffic. It also logs some data, and Opera’s privacy policy has been criticized for data collection.

Vivaldi does not include a VPN, but it offers more granular privacy controls. You can block trackers, disable third-party cookies, and choose which sites can access your camera or microphone. Vivaldi also has a strict no-logging policy and is open-source, meaning its code is publicly available for review. For privacy-conscious users, Vivaldi is generally considered the better choice.

How to Choose

Your decision should depend on what you value most:

• If you want a browser that works well out of the box with minimal setup, choose Opera. It’s great for casual users who want a built-in ad blocker, VPN, and quick access to social media.
• If you spend hours in front of a browser and want to tailor it to your exact workflow, choose Vivaldi. It’s ideal for developers, researchers, and anyone who juggles many tabs and needs powerful organizational tools.

Common Problems and Solutions

Users sometimes report issues with both browsers. Here are a few common ones:

• High memory usage – In Vivaldi, go to Settings > Tabs and enable “Tab Hibernation” to reduce RAM usage. In Opera, close unused tabs or disable extensions.
• VPN not working – Opera’s VPN can be blocked by some networks. Try switching to a different server or disabling it if you don’t need it.
• Extensions not working – Since both are Chromium, most Chrome extensions work, but some may conflict. Try disabling extensions one by one to find the culprit.

Frequently Asked Questions

Is Vivaldi faster than Opera?

In most cases, they perform similarly because they use the same Chromium engine. However, Opera may feel snappier on low-end hardware due to its lighter interface. Vivaldi’s extra features can slow it down slightly if you use many web panels or themes.

Can I use Chrome extensions in Opera and Vivaldi?

Yes, both browsers support Chrome extensions. You can install them from the Chrome Web Store by enabling “Allow extensions from other stores” in the browser settings. This gives you access to thousands of extensions.

Which browser is more secure?

Both are secure, but Vivaldi has a slight edge in privacy because it doesn’t collect user data and is open-source. Opera has a built-in VPN, but it only protects browser traffic and has been criticized for data logging.

Do Opera and Vivaldi sync bookmarks and passwords?

Yes, both offer sync features. Opera syncs via an Opera account, while Vivaldi syncs with end-to-end encryption using a Vivaldi account. You can sync bookmarks, passwords, and settings across devices.

Which browser is better for privacy?

Vivaldi is generally better for privacy because it has a no-logging policy and is open-source. Opera’s VPN and data collection practices make it less privacy-friendly, though it still offers basic tracker blocking.

Are these browsers free?

Yes, both Opera and Vivaldi are completely free to download and use. They are funded through default search engine partnerships and optional donations for Vivaldi.
