file.io alternative
A file.io alternative for temporary, anonymous sharing
Upload without an account, choose exactly how long the link lasts, and share a URL that can’t be guessed. Free, with optional password protection.
Share on your terms
Temporary sharing should be simple and private: no sign-up, an expiry you control, and a link that only the people you send it to can use. Biohost gives you a fixed lifespan of 1, 3, or 5 days, an optional password, and unguessable links.
Pick the lifespan
Choose 1, 3, or 5 days — no guesswork about when it disappears.
No account
Nothing to sign up for; upload and share right away.
Password option
Protect sensitive files behind a password.
Unguessable links
High-entropy IDs keep files from being discovered.

Frequently asked questions
- Is Biohost a good file.io alternative?
- If you want anonymous, temporary sharing with control over how long a link lasts, yes. Biohost lets you choose a 1, 3, or 5 day expiry and optionally password-protect the file. Compare current features and limits before you choose.
- Do links expire?
- Yes. You pick the lifespan at upload, and the file is permanently deleted when it expires.
- Is it anonymous?
- There’s no account and nothing about you is shown on the file page. Limited technical metadata is kept privately for abuse prevention only.
- Can others guess the link?
- No — share links use long, high-entropy IDs, so files can’t be discovered by enumeration.
