Do both devices need to be on the same Wi-Fi?
For the lowest latency, yes — the same LAN is ideal and delivers about 8 ms of processing latency — the rest is your display's own 60 Hz refresh cadence. But Remio also works across the internet using NAT traversal (ICE with STUN). If direct peer-to-peer fails, an encrypted Cloudflare Calls TURN relay carries the stream until the direct path opens up.
Is Remio free?
Yes, completely free — every feature, every platform. That includes 4K streaming, end-to-end encryption, multi-device pairing, and all client apps. There is no paid tier today, and Remio does not sell user data because there is no user data on file to sell.
Is it safe? Could someone else access my Mac?
Every connection is end-to-end encrypted — your screen never touches our servers, and even the relay only sees ciphertext. The six-digit code pairs only your two devices — without it, no one else can connect. Remio cannot decrypt your stream either: the keys never leave your devices.
What platforms are supported?
Remio Host runs natively on macOS, Windows, and Linux. Remio Client runs on iOS, iPadOS, macOS, Windows, and Android. A Linux client is on the roadmap. See the download page for current versions and direct download links.
Do I really not need an account?
Really. No email, no password, no profile, no recovery question. The six-digit code pairs your devices once; they remember each other after that. If Remio were breached tomorrow there would be nothing to leak — Remio does not have your data because it was never asked for.
