| Recipient needs | Nothing | Usually an account | Software and key | Only a browser |
| Can the provider read it? | Yes | Not with a good provider | No | No, except with tampered code |
| Effort | None | Account and setup | High | Low |
| Self-hostable | No | Partly | Runs locally | Yes, open source (AGPL-3.0) |
When something else fits better.
We tell you honestly when you should not use ExoSeal.
Highest stakes
Against a tampered server only a native tool such as age or GPG helps, because no code comes from a server there.
Lasting team access
If several people need a password for a long time, it belongs in a password manager. ExoSeal is for handing something over once.
Large files
ExoSeal is meant for text up to 50,000 characters, not for files.
