Files go directly between devices — no middleman, no upload limits, no waiting. Your data stays between you and your recipient.
Optional encryption for every transfer. Files are protected in chunks so even the coordination server never sees your content.
Chunk-based transfers mean you can pause, resume, and recover interrupted downloads without starting over.
Share files with unlimited people simultaneously. Like torrents, but simpler — create a share, share the ID, and let people download directly from you.
Optional identity management via CrystalID. Manage your devices, track your shares, and build reputation across the network.
No account required for 1:1 transfers. Use Kristall completely anonymously or link a CrystalID for extra features.
