Blip

Open-source Blip alternative

Blip is a popular proprietary large-file transfer app. AltSendme is the open-source alternative: unlimited size, no accounts, a real CLI, end-to-end encrypted P2P on Iroh that can saturate gigabit connections, and full transparency under AGPL-3.0.

FAQ

Is there a free open-source Blip alternative?

Yes. AltSendme is free and open source, with unlimited peer-to-peer transfers, CLI support, and no cloud storage of your files.

Does AltSendme require an account?

No. Drop a file, share a ticket, and transfer directly—no signup. Use the GUI or the sendme-compatible CLI.

Is AltSendme end-to-end encrypted?

Yes. Transfers use QUIC + TLS 1.3 on Iroh. Relays only forward encrypted packets, and native transfers can saturate gigabit links.
