scrt.link vs Tresorit Send
Tresorit Send is end-to-end encrypted and free — but proprietary, files-only, and fixed at 5 GB and 7 days.
Tresorit Send is the free file-sharing arm of Tresorit, a Swiss-Hungarian encrypted-storage company with a serious compliance story. It is genuinely end-to-end encrypted: files are encrypted with AES-256 before they leave your device, and Tresorit states it does not hold the keys — they live in the link.
The limits are fixed rather than chosen: 5 GB per share, up to 100 files, 7 days, and a cap of 10 downloads. It handles files only — no text secrets. And it is proprietary: Tresorit has said an open-source release and third-party audit are "on the roadmap" since 2018, and neither has arrived.
scrt.link is the open-source counterpart: MIT-licensed, self-hostable, files up to 100 GB, expiry from 10 minutes to 30 days, and text secrets alongside files.

Key differences
Both are end-to-end encrypted — one you can verify
Tresorit Send encrypts client-side with AES-256 and says the keys are stored in the link, not on their servers. We have no reason to doubt it. But the code is proprietary, and an open-source release plus a third-party audit have been promised since 2018 without materialising. With scrt.link, the encryption code is MIT-licensed and you can read it before you trust it.
Fixed limits versus chosen limits
Tresorit Send gives you 5 GB, 7 days and 10 downloads — no dials. That is fine when it fits and unhelpful when it does not: you cannot make a link die after one download, or in ten minutes, or keep it alive for a month. scrt.link lets you set expiry from 10 minutes to 30 days and view limits from 1 to 1,000.
Files only
Tresorit Send moves files. It has no text-secret feature, so the archive password or API key that goes with the file ends up in email or Slack anyway. scrt.link handles both, with the same encryption and the same self-destructing links.
What Tresorit brings that we do not
Tresorit is a substantial company with Swiss data residency, an established compliance posture, and a full encrypted-storage product behind Send. If you are already a Tresorit customer, or your procurement team wants that specific jurisdiction and certification story, that is a real advantage.
