Chrome Extension vs Web App: Which Should You Build?
Both can solve the same problem — but the right format depends on where your user already is. A practical decision framework.
If your tool augments what users already do on the web — read articles, watch videos, manage email, browse stores — a Chrome extension almost always beats a standalone web app.
Pick a Chrome extension when
- Your tool acts on content the user is already viewing.
- You need to read or modify the DOM of third-party sites.
- You want to live in the user's browser without them visiting a URL.
- Your value is contextual — 'do X to whatever I'm looking at right now'.
Pick a web app when
- Users come to you intentionally with their own data or task.
- You need a large screen, complex layout, or multi-step flow.
- You're billing, onboarding, or running long-form workflows.
The both-and answer
Most successful tools ship both — a web app as the home base, and a Chrome extension as the daily-use surface. ManifestGo lets you ship the extension half in an afternoon.
