ClaimAlterSend is a private file transfer tool for sending files directly between devices with no accounts, servers, or size limits. Free and open source for Mac, Windows, Linux, iOS, and Android.
Overview
AlterSend is a private file transfer tool for sending files directly between devices. Its core workflow is simple: pair two devices with a QR scan or join code, open an encrypted channel, and move files without uploading them to a server.
The product positions itself as peer-to-peer, end-to-end encrypted, and free of accounts or size limits. The site also says it works across Mac, Windows, Linux, iOS, and Android, making it a cross-platform option for people who need to share files without using a cloud upload service.
Features
Peer-to-peer encrypted transfers
Files move directly between devices on a peer-to-peer network and use an end-to-end encrypted channel.
No server-side file handling
Transfers do not go through a server, and the product copy emphasizes that files never touch AlterSend servers because there are none.
Unlimited file sizes
The page says there is no size limit, with the same transfer flow for very small or very large files.
Cross-platform support
AlterSend is described as working across Mac, Windows, Linux, iOS, and Android with one shared protocol.
Open-source software
The site says the project is open source and Apache-2.0 licensed, allowing users to audit, fork, or self-host the code.
Use cases
Personal device-to-device sharing
Send documents, photos, or archives between your own devices without creating an account or uploading to cloud storage.
Large-file transfer
Move large files when upload size limits or cloud transfer steps would be inconvenient, since the product says there are no size limits.
Cross-platform remote sharing
Share files over the internet between different devices and platforms using the app’s shared protocol and encrypted channel.
Open-source deployment and review
Use the open-source codebase if you want software you can inspect, fork, or run yourself rather than relying on a closed service.
