Electron

Electron bundles Chromium and Node.js into a desktop app. It is the industry standard (VS Code, Slack, Discord) despite the file size.

When to Use

• Rich Capabilities: If you need full Node.js access (Filesystem, Serial Port).
• Consistent UI: Loops exactly the same on Windows/Mac/Linux (Pixel Perfect).
• Legacy: Migrating an existing web app to desktop with zero changes.
