While Electron can help make app development easier, its use does have some downsides. Since every Electron app needs to include both the full Chromium and Node.js packages in the executable file, they require more storage space and memory than a native app. These requirements increase if you run multiple Electron apps, since each app includes its own copy of Chromium and Node.js. Additionally, security updates to Chromium might not make it to an Electron app promptly, potentially leaving it vulnerable to exploits already discovered and patched in the full web browser.
NOTE: Popular apps built using Electron include Microsoft Teams, Slack, Trello, Discord, and Visual Studio Code.
