scrt.link vs Yopass

Both are open source and genuinely end-to-end encrypted. The difference is scale, expiration, and what you get without a licence.

Yopass is a good tool and we will not pretend otherwise. It encrypts with OpenPGP in the browser, the decryption key never reaches the server, and it is Apache-2.0 licensed. If you want a small Go binary to self-host, it is a strong choice.

The honest differences are practical rather than philosophical. Yopass caps uploads at 1 MB without a paid licence and offers exactly three expiration options — 1 hour, 1 day, 1 week. Its branding, OIDC login, audit logs, read receipts and webhooks now sit behind a €149/year business licence.

scrt.link is a hosted product with the same zero-knowledge model: files up to 100 GB, expiration from 10 minutes to 30 days, view limits up to 1,000, and accounts and teams built in.

Key differences

The security model is the same — that is the point

Both tools encrypt in the browser and keep the key out of the server. Yopass uses OpenPGP, scrt.link uses AES-GCM via the Web Crypto API. If your only requirement is "the server must not be able to read this", Yopass meets it, and we would rather say so than invent a difference.

Open core, and where the line falls

Yopass has moved to an open-core model: a €149/year business licence gates custom branding, OpenID Connect, audit logging, read receipts, webhooks, secret requests — and lifts the 1 MB upload cap. That is a fair way to fund the work, but it means the free edition is more limited than it first appears.

Files, and how big they get

Without a licence Yopass caps uploads at 1 MB, which rules out most real files — a database dump, a design archive, a set of client documents. scrt.link handles files up to 100 GB, encrypted in the browser and streamed, on the same one-time links.

Expiration windows

Yopass offers three fixed options: 1 hour, 1 day, 1 week. That is often enough, but not when a contractor needs the credential on Monday and it is Friday, or when you want a link that dies in 10 minutes. scrt.link runs from 10 minutes up to 30 days.

Which one should you use?

Choose scrt.link if…

  • You need to send real files, not just a 1 MB payload.

  • You want expiration windows shorter than an hour or longer than a week.

  • You want branding, read receipts and file requests without buying a licence.

  • You want a hosted service with accounts and teams rather than something to operate yourself.

Choose Yopass if…

  • You want to self-host a single, small Go binary and be done with it.

  • Apache-2.0 matters to you, or you want OpenPGP specifically.

  • You never need to send more than 1 MB, and 1h/1d/1w covers your needs.

  • You want zero accounts anywhere in the system, by design.
