Peer-to-peer screen sharing, straight from your browser
On Linkside, your screen video doesn't route through an application server. The two browsers connect to each other, and the media takes the direct path.
What peer-to-peer means here
When you share your screen, your browser and your viewer's browser negotiate a WebRTC connection with each other. Once it's up, encrypted video flows across that connection directly — machine to machine. There is no Linkside media server in the path, because there is no Linkside media server. If you watch your network traffic during a direct session, you'll see the video flowing to your peer — the only packets headed our way are a thin signaling channel that carries connection metadata, never media.
Three consequences worth caring about
Latency. Your video takes the shortest network path between the two of you instead of a detour through a data centre. For screen sharing — where someone says "click that" and watches you do it — that round-trip is the experience.
Privacy. Content that never lands on our servers is content we cannot store, scan, or hand over. The privacy claim isn't a policy promise; it's an architecture. More on that on the private screen sharing page.
Cost. The bandwidth is yours and your viewer's. That's the reason Linkside is free for direct connections — there's no per-minute media bill for us to pass on to you.
The parts that aren't peer-to-peer
Any honest P2P product has to admit the exceptions. Browsers can't find each other unaided, so a small signaling server brokers the introduction — it relays connection offers, never media. STUN servers help each browser learn its own public address. And when a network refuses direct connections outright (some corporate firewalls, double NAT), traffic falls back to a TURN relay, which forwards encrypted packets it cannot decrypt. We wrote up the whole dance in a step-by-step walkthrough.
P2P-first, not P2P-only
Linkside always tries the direct path first and uses the relay only when the network leaves no choice. Free rooms include a 5-minute relay trial; a licence removes the relay limit. Direct sessions have no limit at all.
