AlterSend review
A private, account-free way to move files directly between devices.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
AlterSend is an open-source file transfer application for people who want to send files directly between devices without creating an account or storing files in the cloud. It supports Windows, macOS, Linux, iOS, Android, and the web, making it suitable for individuals and teams moving files across mixed device environments. QR-code and short-code pairing simplify device connections, while recipients can download shared files through a browser link without installing the application. End-to-end encryption applies to transfers, and folder support extends the service beyond individual files.
The free plan covers peer-to-peer transfers, requires no account, and keeps direct transfers unlimited. It does not include cloud storage. AlterSend Pro Monthly and AlterSend Pro Yearly are optional subscriptions that raise limits for transfers routed through relay servers and provide priority for relayed transfers. This pricing structure fits users whose devices can connect directly, while those who regularly need relay routing may need a paid plan. Relay size limits are described in the app and may change, so the paid tiers are better understood as access to higher relay allowances rather than a fixed storage package.
AlterSend’s main advantage is its focused transfer workflow: pair devices, send files or folders, resume interrupted transfers, and fall back to relay servers when a direct connection is unavailable. Its broad platform coverage supports desktop-to-mobile transfers, and browser downloads reduce friction for recipients. The trade-off is a narrower service ecosystem, with no verified download tracking, documented API access, integrations, or custom branding. Choose AlterSend for private, direct transfers across personal devices; choose another service if your workflow depends on administrative tracking, automation, or broader collaboration features.
