Video sharing: CloakShare's unique advantage
Sizle does not offer secure video sharing. CloakShare lets you upload MP4, MOV, or WebM files and automatically transcodes them to adaptive HLS streaming with 720p and 1080p quality tiers. Every video frame is watermarked with the viewer's email. Watch-time analytics show exactly how much each viewer watched.
For teams that need to share both documents and video content, CloakShare eliminates the need for separate tools and gives you unified analytics across all content types.
Self-hosted option
CloakShare is open source (MIT license) and self-hostable via Docker. Run it on your own infrastructure for complete data sovereignty. Sizle is a closed-source SaaS with no self-hosting option.
