What Wormhole is
Open-source end-to-end-encrypted file sharing from the Socket team.
Wormhole is the leading open-source, end-to-end-encrypted browser file share. Files are encrypted in the browser before upload, and Wormhole's servers never see the plaintext. It is the right answer when E2E is a hard requirement.

Frequently asked
Is Wormhole more private than quik.space?
For the file contents, yes. Wormhole's servers never see the plaintext because encryption happens in the browser before upload. quik.space has HTTPS in transit and at-rest encryption, but the keys are managed by the host. If E2E is non-negotiable, choose Wormhole.
Why doesn't quik.space do end-to-end encryption?
E2E forces tradeoffs that conflict with quik.space's other primitives. Recipient previews would need to decrypt in the browser. Email recovery would not work because the host cannot re-derive the key. Spaces with multiple uploaders would need shared key management. Those features are part of the value proposition, so E2E is not currently on the roadmap.
Is Wormhole really free forever?
It has been free since launch and is operated by Socket as a side project. There is no monetization, which is great until there isn't. quik.space's pay-per-action revenue model is what funds the free tier and lets us extend retention if asked.
Can I send a 10 GB file on quik.space?
Not yet. The current XL upload caps at 5 GB. If you need 10 GB in a single shot and the recipient is online soon, Wormhole is a better fit today.
