The name Voomly Cloud covers two things. It is the $49 plan, and it is the desktop app that Voomly's help center calls the preferred way to sign in to all its products. For someone choosing a host, the bandwidth row in the plan table decides more than either.
Every plan, the free one included, stores your uploads and streams them through an ad-free 4K and HDR player with sharing, custom thumbnails, comments and any player colour you like. Voomly's homepage says it delivers over the same content delivery network as Amazon Prime and Hulu and protects streams with SSL/TLS encryption. Those are the vendor's own claims, so judge load time and buffering during the trial, on your own pages and your visitors' devices.
Voomly publishes no cap on plays or views. The meter is monthly bandwidth: 5 GB on Light, 20 GB on Basic and unlimited from Plus up. To size that, take a 20-minute video watched halfway at 1.5 Mbps, which moves roughly 110 MB per play. Light covers about 45 of those plays a month and Basic about 180, so anything fed by paid ads belongs on Plus or higher.
The plan comparison names no domain locking, DRM or download protection. A course seller who worries about piracy will get more from Spotlightr or Panda Video. If the only question is the hosting bill, Bunny Stream vs Voomly sets a per-GB pipe against this flat fee, and Voomly vs Adilo weighs it against another host that does not meter streaming.
