## What it is
AlterSend is an open-source cross-platform app for sending files directly between devices over the internet via P2P connections, with end-to-end encryption and no cloud storage. It supports pairing devices via QR codes, browser-based receiving via share links, and has no file size limits or accounts.

## Use cases
- send large files between my devices without cloud storage
- transfer files to a friend without uploading to a server
- share files with someone who doesn't have the app installed
- send files between phone and computer privately
- replace WeTransfer with a private open-source alternative
- transfer files over the internet without size limits
- pair my devices once and send files anytime

## When to choose
- you need direct device-to-device transfers with no cloud intermediary
- you want end-to-end encryption and no accounts
- you need to send very large files without upload queues
- the recipient should be able to download via a browser link without installing anything
- you want an open-source, cross-platform AirDrop/WeTransfer alternative

## When to avoid
- you need files stored in the cloud for later access or async sharing
- you need team collaboration features or shared folders
- you require a guaranteed transfer when the sender's device is offline
- you need compliance-audited enterprise file transfer
