| Solution | Background Play | No Ads | Download | Cost | |----------|----------------|--------|----------|------| | YouTube Premium | ✅ | ✅ | ✅ | Paid | | Brave Browser (web) | ✅ (with workaround) | ✅ | ❌ | Free | | Viddle (third-party iOS app) | ✅ | ✅ | ❌ | Free (limited) | | Yattee (open-source) | ✅ (via custom instance) | ✅ | ❌ | Free |
