Native Mac Apps vs Electron for Writing: Why Performance Matters

You're typing away, and there's a tiny but perceptible lag between keystroke and character. The fans spin up even though you're just writing text. The app takes three seconds to launch. If this sounds familiar, you're probably using an Electron app. For many writing tasks, native Mac apps provide a noticeably better experience.

What's the Difference?

Native Mac Apps

Built using Apple's development frameworks (AppKit, SwiftUI), native apps are compiled specifically for macOS. They speak the operating system's language directly and can access all system features efficiently.

Electron Apps

Built using web technologies (HTML, CSS, JavaScript), Electron apps run inside a bundled Chromium browser. This allows developers to use one codebase for Mac, Windows, and Linux - at the cost of efficiency.

Why This Matters for Writers

Responsiveness

Native apps feel instantly responsive. The lag between typing and text appearing is imperceptible. Electron apps often have subtle delays that may not be consciously noticeable but contribute to fatigue over long sessions.

Resource Usage

A native writing app might use 50-100MB of RAM. An Electron app doing the same thing often uses 300-500MB or more - it's running an entire browser in the background. This affects system performance, especially on older machines or when running multiple apps.

Battery Life

If you write on a MacBook, battery life matters. Electron apps consume more power due to their higher CPU and memory usage. Writers who work in cafes or on flights feel this difference.

System Integration

Native apps integrate better with macOS features: proper keyboard shortcuts, system-wide spell check, Services menu, native notifications, and seamless iCloud integration. Electron apps often miss these subtleties.

Startup Time

Native apps launch almost instantly. Electron apps need to boot up a browser first, leading to delays of 2-5 seconds or more. When you're ready to write, waiting for your app is friction.

Why Electron Exists

Electron isn't bad - it solves real problems:

• Cross-platform development - one codebase for all systems
• Faster development - web technologies are widely known
• Lower cost - no need to hire platform-specific developers

For complex apps that need to run everywhere (like Slack or VS Code), Electron makes business sense. But for a Mac-only writing app, the tradeoffs often don't favor users.

How to Tell What You're Using

Check these signs of an Electron app:

• Activity Monitor shows multiple processes for one app (especially "Helper" processes)
• High memory usage for simple functionality
• Web-like interface that doesn't quite feel like other Mac apps
• Keyboard shortcuts that don't follow Mac conventions
• App contents include Chromium framework (right-click → Show Package Contents)

Native Mac Writing Apps

If you prefer native performance, consider:

• iA Writer - native Swift app
• Ulysses - native Mac app
• Bear - built on Apple frameworks
• JustWrite - native macOS app
• Scrivener - native Mac development

Electron Writing Apps

For comparison, these popular writing tools use Electron:

• Notion
• Obsidian
• Typora

These are excellent apps - the Electron tradeoff may be worth it for their features. But if you're sensitive to performance or use an older Mac, consider native alternatives.

Making the Right Choice

Technology choices are personal. Some writers don't notice Electron's overhead, and the cross-platform features or specific capabilities might be worth it. But if you want your writing app to feel like a natural extension of your Mac - fast, efficient, and respectful of system resources - native apps deliver that experience.
