Cross‑Platform Desktop Development: QQ’s Adoption of Electron and Microsoft Teams’ Migration to WebView2

According to InfoQ, the new Windows QQ entered public testing on April 23, 2023 with a brand‑new QQ NT architecture that unifies the code base across Windows, macOS, and Linux, delivering a consistent UI and performance on all three platforms.

QQ’s multi‑platform strategy builds on the NT architecture first seen in QQ for macOS and later in QQ for Linux 3.0, which supports both x64 and arm64 and improves appearance, efficiency, and entertainment features.

To achieve code reuse and a uniform user experience, the QQ team chose Electron as the UI layer for the desktop client, leveraging its JavaScript, HTML, and CSS stack on top of Chromium and Node.js while applying extensive optimizations to mitigate Electron’s typical memory overhead.

Electron enables sharing of web resources between desktop and web versions, reducing development effort, but still requires platform‑specific handling to ensure stability across Windows, macOS, and Linux.

Microsoft’s Teams application provides a contrasting case: after years of using Electron, Teams migrated to the Edge WebView2 rendering engine in early 2024, cutting startup speed, meeting‑join speed, and memory consumption by up to 50% and reducing disk usage by up to 70%.

Benchmarks from third‑party GigaOm show Teams 2.0 launching twice as fast, joining meetings twice as fast, and using significantly less memory and storage compared with the Electron‑based version.

Experts such as Tencent’s engineer Fang Qiufang and Alibaba’s senior wireless expert Huang Gang (a.k.a. Tengyuan) note that cross‑platform frameworks involve trade‑offs: they simplify development and code sharing but increase the cost of handling platform differences and can sacrifice native performance or features.

Choosing the right framework depends on product requirements: highly stable, performance‑critical front‑ends may favor native solutions, while rapidly evolving or less performance‑sensitive apps can benefit from hybrid approaches like Electron, React Native, Weex, or Flutter.

The article concludes that there is no one‑size‑fits‑all solution; teams must weigh development cost, flexibility, and performance when deciding between native, hybrid, or cross‑platform technologies.
