Ultra Explorer vs MultCloud
Ultra Explorer moves data directly from your computer or your own server: no third-party relay, no monthly traffic quota, and your local disks in the same window.
Ultra Explorer runs on your computer, or on your own server with the Docker version. Files travel straight between your storages and your machine, your credentials stay with you, and there is no limit on how much you transfer. MultCloud runs transfers on its own servers: your files and access tokens go through its infrastructure, and the free plan stops at 5 GB of traffic per month.
Ultra Explorer
Free, Pro or Lifetime
Free plan includes full dual-pane file management across 40+ clouds, durable transfers, and Docker container. Pro upgrade unlocks Disk Space Analyzer, Synchronizations, and Global Search.
MultCloud
Free (5 GB of traffic per month); paid plans from $59.99/year or $249 lifetime
Direct transfers from your machine, with no traffic quota.
