I haven’t used Netlify but it does provide some nice features. Some things that Netlify does that would be hard or at least require some work with Confetti:
- Atomic Deploys
- Unlimited Snapshots / Versioning & Rollbacks
- Instant Cache Invalidation (CloudFront cache invalidation times vary)
- Automated Builds (can be done with CI though)
- Branch Based Split Testing
- Form Submission Hooks
- Multiple Environments Support (dev/staging/…) (would be possible by creating multiple sites)
- Single Page App Prerendering
These are mostly copied from the Netlify features page. Netlify’s free plan is definitely a strong competitor 
That said I’m more comfortable with AWS than a smaller platform like Netlify and haven’t had a strong need for any of the additional features.
Also Confetti was created at a time when Netlify didn’t exist or at least was still relatively unknown.
Maybe I should have turned it into a company too
