Share your screen without installing anything

You want to help someone — parents, grandparents, customers — and no one should have to deal with downloads and accounts? With Auffi, the person helping just opens their browser, types a 9-digit code and is connected: no installation, no account. Free, open source, servers in Germany.

Connected in three steps

Open auffi.app — in the browser, no download, no account.
Enter the code — the 9-digit code the other person gives you.
Connect — the other person confirms, and the session starts.

Note: The person whose screen is shared runs the small Auffi sharer once (Windows or Linux) and reads out their code. The helping side stays entirely in the browser — that is the difference from TeamViewer, AnyDesk or RustDesk, which require an app on both sides.

Why this makes things easier for the person helping

No download on the helping side — nothing that gets blocked on corporate laptops.
No account, no sign-in — one code is enough, valid for 10 minutes.
GDPR-compliant: servers in Germany (Frankfurt), no trackers, end-to-end encrypted.
Open source (AGPL-3.0) and self-hostable.

Frequently asked questions

Can you really share a screen without installing anything?

For the helper, yes: they just open auffi.app in a browser, type a 9-digit code and are connected — no download, no account. Only the person whose screen is shared runs the small Auffi sharer once.

Why does the sharing person still have to run something?

For security, browsers may not silently expose a whole screen plus remote control. So the small Auffi sharer (Windows or Linux) runs on the shared side. The helping side stays entirely in the browser.

Is it free?

Yes, completely. Auffi is open source under the AGPL-3.0 — free for private and commercial use, with no session limit.

Is the connection secure?

Every stream is end-to-end encrypted with DTLS-SRTP (WebRTC). The 9-digit code expires after 10 minutes, the server rate-limits guess attempts per IP, and the sharing person actively confirms every connection.

Does it work on any device?

The helper only needs a modern browser (Chrome, Edge, Firefox; Safari with limitations). The sharer for the shared side runs on Windows and Linux (macOS coming).
