SHAREit works. But it's full of ads, collects your data, and doesn't work on Mac or Linux. Seyfr gives you the same fast Wi-Fi transfer — without any of that baggage.
Free · No ads · No account · Works on Android, iPhone, Mac, Windows and Linux

SHAREit shows ads aggressively — before transfers, after transfers, in the app interface. Seyfr has zero ads, zero banners, zero interstitials. The app has one job: transfer your files.
SHAREit's Mac support is extremely unreliable — it requires a desktop app that many users report doesn't connect properly. Seyfr works in any browser on Mac — Safari, Chrome, Firefox. No Mac app installation needed. Just scan a QR code.
SHAREit has no Linux support at all. Seyfr works in any browser on Ubuntu, Fedora, Arch, Debian, and every other Linux distribution. This makes Seyfr the only SHAREit alternative that fully supports the Linux desktop.
SHAREit has faced significant privacy concerns — it has been flagged by security researchers for collecting extensive user data. Seyfr has no backend servers, and collects zero data. Files go directly from device to device.
SHAREit requires both devices to be on the same Wi-Fi hotspot (one device creates a hotspot, the other connects). Seyfr works over your existing Wi-Fi router without any hotspot creation, and also works across different networks using hole-punching technology.
If you use SHAREit to transfer files from your Android phone to your Windows PC at the office, but have a Mac at home — Seyfr is the only free option that works on both. The same QR code method works identically on Windows and Mac.
In India, SHAREit and Xender dominate because they're optimized for low-bandwidth environments and Android-to-Android transfers. Seyfr works equally well on Indian networks — it uses your existing Wi-Fi router (no internet required for the transfer), transfers at full local Wi-Fi speed, and has no ads to slow down or interrupt the experience.
Same fast Wi-Fi transfers. Zero ads. Works on Mac and Linux too.
Yes — Seyfr. It's completely free and has zero ads. Files transfer wirelessly at full Wi-Fi speed between Android, iPhone, Mac, Windows, and Linux — all without any advertising.
Seyfr is the best Xender alternative for users who need Mac or Linux support. For pure Android-to-Android transfers, LocalSend is also good. For transfers involving Mac, Seyfr is the only strong free option.
Yes. Seyfr transfers over your local Wi-Fi network. No internet connection is required for the file transfer itself — making it work even on limited data plans or in areas with poor connectivity.
Yes. Seyfr has no backend servers storing your files. Files go directly from device to device. There are no hidden tracking libraries, no data harvesting. End-to-end encrypted.
