Electron vs native apps: which performs better and why?

The question is about Electron .

Answer:

Native apps outperform Electron on nearly every raw benchmark: faster cold start, lower memory baseline, and direct access to GPU and OS APIs. The gap exists because Electron bundles a full Chromium browser plus a Node.js runtime inside every build instead of talking to the operating system directly, and that extra layer is exactly what VS Code and Slack accept in exchange for shipping one codebase to Windows, macOS, and Linux.

Dimension	Electron	Native (Swift/AppKit, WinUI/.NET)
Runtime	Bundles Chromium and Node.js inside every build	Compiles directly against the OS toolkit, no embedded browser
Cold start	Slower, the app spins up a browser process before rendering	Faster, the OS loads a compiled binary that talks to system APIs directly
Memory baseline	Higher, Chromium reserves a large chunk of RAM before app code even runs	Lower, no browser process sitting underneath the UI
Platform API access	Routed through Node.js/Electron bindings, sometimes lagging behind the newest OS features	Direct access to platform APIs the day the OS ships them
Install size	Larger, installers commonly land between 100MB and 300MB	Smaller, since there is no runtime to bundle

When is Electron's overhead acceptable?

Electron works when the app is not CPU-bound and the team already writes HTML, CSS, and JavaScript. Text editors, chat clients, and internal tools spend most of their time idle or waiting on I/O, so the Chromium overhead rarely shows up as a user-facing problem. VS Code and Slack both prove this at scale: neither is the fastest binary on the machine, but both are fast enough for the workload they handle, and shipping one JavaScript codebase across three operating systems cuts development cost significantly.

When does native performance matter enough to choose it?

Native wins whenever the app pushes hardware hard: video editing, audio processing, 3D rendering, or anything that competes for CPU and GPU cycles with the OS itself. Because a native app is compiled directly against a platform's own toolkit, such as Swift with AppKit on macOS or WinUI with .NET on Windows, it reaches system APIs and hardware without a browser engine sitting in between. That direct path is also why native apps start faster and hold a lower memory floor even before any application logic runs.

Which one fits the project?

Choose Electron when cross-platform reach and a shared web codebase matter more than shaving milliseconds off startup or megabytes off memory use. Choose native when the app is performance-critical, needs the latest OS-specific APIs immediately, or has to run efficiently on constrained hardware. The performance question rarely has one universal answer; it depends on whether the bottleneck is engineering time or runtime resources.
