The modern desktop browser market increasingly resembles a bloated "super application Frankenstein"—cloud storage, AI chatbots, crypto wallets, and news feeds forcibly stuffed beside our address bars. But we must ask: as a web browser, how does its core "rendering webpages" capability actually perform today?

A browser must excel at its fundamental browsing functions before earning the right to consider additional features. To find answers, I conducted a rigorous, pure performance assessment of 19 mainstream and regional browsers globally under macOS.

Testing Standards and Contenders

This evaluation completely abandoned all subjective experiences of additional features, focusing solely on two hard metrics:

  • Core Rendering Performance: Tested using the industry's most authoritative Speedometer 3.0 benchmark tool. It simulates complex DOM operations and frontend framework operations in modern webpages—higher scores mean faster webpage response.
  • "Bloat" Index: Comparing the browser's initial installation package size against actual disk usage after installation.

Note: Due to macOS system limitations, some mobile-exclusive or Windows-only browsers (Samsung Internet, Android built-in, Sogou, etc.) were not included in this test.

Part 1: The Absolute Performance Battle (Speedometer 3.0 Scores)

We ranked all 19 tested browsers by performance score from highest to lowest. The results not only confirmed the strength of industry leaders but also exposed the shame of many repackaged browsers.

18Zen32.51.9
19QQ Browser22.22.4

Key Findings:

  • Chrome Remains Unshakable: With a high score of 52.3, Chrome proved its dominant position relies not just on pre-installation—the V8 engine's底层 optimization remains the industry ceiling.
  • Underdog Success Stories: Coc Coc and Vivaldi, both secondary developments based on Chromium, achieved scores approaching or even exceeding Safari. As long as manufacturers focus efforts where it matters, Chromium kernel potential is enormous.
  • Fallen Giants and Bottom Shame: Firefox, the open-source community's pride, scored only 36.6—engine performance clearly falling behind. Meanwhile, China's QQ Browser scored merely 22.2, not only finishing last but even losing to WeChat's built-in simplified browser (44.3 points), raising serious concerns about basic user experience.

Part 2: Browser "Bloat" Real Data Revealed

Speed alone isn't enough—we must see how much storage browsers consume for that performance. We compared initial installation package sizes against actual disk usage after installation (ranked by post-installation size, descending):

The Shame Column Special: Puffin Browser, A "Cloud" Scam

In this test, one browser didn't even get a chance to score: Puffin, claiming "cloud acceleration" with only a 61MB installation package.

As a browser marketing itself as modern and secure, Puffin's product logic is extraordinarily arrogant and anti-user:

  • Forced Login Prison: Opening the browser, you don't even see an address bar—instead, you're greeted by a forced registration/login interception page. Before rendering any webpages, it demands user personal privacy first.
  • Shameless Paywall: After patiently logging in, it directly displays an "Account Details" page, forcing you to purchase a Puffin 365 subscription to use it normally.

This transcends "browser" territory. Software that can't even provide basic free browsing and must charge for "cloud rendering" services appears ridiculously laughable in today's performance-surplus desktop environment. Strongly recommend avoiding.

Five Browser Camps Fully Dissected

To help you see these browsers' true faces, we跳出 manufacturers' marketing speak and divide them into five camps for thorough examination:

1. Industry Dominators and System Benchmarks

Google Chrome: Undisputed first choice. Blazing-fast rendering comes at the cost of greedily devouring memory. It's powerful but has grown arrogant occupying 70% market share.

Apple Safari: Mac users' optimal solution (48.2 points). It completely outperforms all opponents in power efficiency and energy consumption ratio, but support for cutting-edge Web API always lags half a step behind.

Microsoft Edge: The dragon-slayer becomes the dragon. Once a lightweight good product, now stuffed by Microsoft with massive private additions (shopping, games, news feeds)—the heavy burden has seriously dragged down its basic rendering performance.

2. Geeks, Open Source, and Privacy Defenders

Brave: Blocks trackers and ads directly at the底层 level. Because it eliminates webpage-slowing junk scripts, its score even surpasses native Chrome (48.4 points). Drawback: built-in cryptocurrency (BAT) feels somewhat superfluous.

Vivaldi: A heavy knowledge worker's divine tool. Even piling on令人发指的 complex UI and built-in email, the chassis remains extremely stable (49.7 points), proving "many features" doesn't equal "slow rendering."

Mozilla Firefox: The world's only mainstream survivor still persisting with an independent engine (Gecko). Heartbreakingly, its performance has indeed been generationally pulled away by the V8 engine (36.2 points). Using it is more about faith in resisting browser engine monopoly.

3. UI Form Pioneer Experimental Fields

Arc & Zen: They attempt to break the stale "top address bar + tabs" interaction, adopting sidebar logic and minimalist borderless design. Arc wears a gorgeous Swift coat, while Zen is a Firefox kernel reshelling (32.5 points). They're extremely beautiful but sacrificed considerable basic operational efficiency for it.

4. Powerful Regional "Local Kings"

Coc Coc (Vietnam) & Naver Whale (Korea): They hold extremely high market share in their respective countries. Particularly Coc Coc, not only adding "powerful audio/video sniffing downloads" fitting Vietnamese national conditions, but its score killed its way to second place overall (50.7 points)—their team's底层 optimization control ability is令人赞叹.

5. Chinese "Ecosystem Binders" and Magical Reality

This camp's commonality: webpage rendering is often just their side function; their true purpose is completing big tech's traffic closed loops. But within this, the most dramatic contrast was born.

Quark: Once an ad-free minimalist browser, now completely mutated into a giant "cloud storage + AI problem solving + short video" Frankenstein. Its 709.3MB bloated size and mediocre 40.8 score are the heavy price of its team deviating core energy from webpage rendering—putting the cart before the horse.

360 Extreme Browser: Due to大量陈旧 government and banking systems in China still死死 binding IE, its dual-core architecture (Blink + Trident) became a heavy historical burden. To maintain backward compatibility, its performance ceiling has been彻底 locked (38.4 points).

QQ Browser: The shame column of the entire field. It finished last with a score of 22.2 points. As a proper independent desktop browser, its底层 engine maintenance has been completely marginalized. It's essentially a "desktop tumor" pushing Tencent news and funneling traffic to the Tencent family ecosystem—keeping you trapped in its ecosystem matters far more than letting you quickly open external webpages.

WeChat Built-in Browser (Embedded WebView): The biggest contrast and surprise of the entire field.令人眼前一亮, as a built-in component without even an independent entry point, its score actually reached a stunning 44.3 points. Not only did it crush its own promoted desktop "QQ Browser" with an overwhelming advantage, it even surpassed Microsoft's carefully crafted Edge!

Why? Because Tencent's entire commercial empire (mini-programs, official account articles, H5 mini-games) heavily depends on this底层 webpage rendering capability. If WeChat's built-in WebView lags, the entire WeChat ecosystem closed loop instantly collapses. Therefore, Tencent must—and can only—spare no effort to equip WeChat with the latest, most optimized Chromium/X5 rendering kernel.

The Ironic Reality: Tencent absolutely has the capability to build an excellent browser scoring 44+ points, but they applied this technology to WeChat's built-in component while letting the nominal flagship "QQ Browser" completely rot.

Summary and Ultimate Selection Guide

When "browsing webpages" itself is the browser's highest priority, our choices become very clear:

  • Pursuing Extreme Performance and Full Network Compatibility: Don't overthink it—install Google Chrome.
  • Mac Users with Battery Anxiety: Native Safari is sufficient for 99% of needs.
  • Wanting High Customization Without Sacrificing Speed: Geek first choice: Vivaldi or built-in ad-blocking Brave.
  • Avoid Pitfall Warning: Stay away from Edge approaching 1GB and increasingly bloated, resist Puffin forcing login and payment, and avoid QQ Browser with bottom-tier performance only caring about traffic funneling.

A browser should be "a window opening to the world," not "a room locking you inside." Browsers that can't even render webpages quickly don't deserve to talk about ecosystems and futures.
