Yes. AlterSend is free and open source (Apache-2.0). There's no Pro tier or subscription — the peer-to-peer transfer core stays free.

Is there a file size limit?

No. WeTransfer's free plan stops at 2 GB per transfer. AlterSend has no limit — you're transferring directly rather than uploading to a service, so a photo or a 200 GB folder use the same flow.

Where are my files stored?

Nowhere. Files travel straight from one device to the other, end-to-end encrypted, and are never stored on a server. WeTransfer, by contrast, uploads and holds every file on its own cloud.

Do the files expire like on WeTransfer?

There's nothing to expire — AlterSend has no download links and stores no files. WeTransfer deletes free transfers after 7 days.

Do I need an account or email?

No. WeTransfer asks for your email (and the recipient's). AlterSend asks for nothing — open the app, pair with a QR code, and send.

When should I use WeTransfer instead?

WeTransfer's one real edge is that it's asynchronous: you upload, share a link, and the recipient downloads whenever — even if you've gone offline. AlterSend is a live, direct transfer, so both devices need to be online at the same time. For a fire-and-forget link to someone in another timezone, WeTransfer fits; for private, unlimited, instant transfers, AlterSend wins.
