Play with lower ping and fewer lag spikes.
ZeroLag measures the path your game traffic actually takes, and moves it only when the alternative is measurably better. When it isn't, it doesn't connect — we don't promise an improvement we can't measure.

Using ZeroLag
Paste a server. See every route. Take the fastest one.
ZeroLag does not guess. You give it the server you are about to play on, it measures the direct route and every ZeroLag route, and you connect to whichever is genuinely faster.
- 1
Paste your server address
Copy the connect string from your game's server browser and drop it in.
- 2
ZeroLag measures every route
Your direct route and each ZeroLag location are tested at the same time, against that exact server.
- 3
Connect to the fastest
Routes are ranked by real measurements. The best one is recommended.
- 4
Play on a better route
Only your game traffic changes lanes. Everything else on your connection is untouched.
Illustrative example. Real figures depend on your connection, your ISP and the server you are playing on — sometimes the direct route wins, and ZeroLag will tell you so.
An animation of the ZeroLag desktop app: a server address is entered, the direct route measures 78.4 ms, the istanbul-1 route measures 54.3 ms, and the app connects through istanbul-1.

Your ISP doesn't route for games.
It routes for cost.
Your packets take the cheapest path, not the fastest.
Most residential ISPs dump traffic onto the nearest peering exchange. A 30ms game can become 110ms because your packets detoured through a congested IX two countries away.
Variable latency wrecks aim before high latency does.
Flat 70ms is playable. 35ms that spikes to 120ms every few seconds is not. Public routes introduce jitter at every hop — that's what makes shots feel like they went through the enemy.
"Gigabit fiber" does nothing for packet loss.
Bandwidth and latency are not the same thing. A 2% packet loss rate on your ISP's backbone makes every competitive match feel unplayable no matter how fat your pipe is.
Only your game traffic
changes lanes.
ZeroLag compares your normal game route with its available paths. When its best, most direct path to the game server looks healthier, only the selected game's packets change lanes. Everything else stays on your normal connection.
The same game server, measured over two paths
A more direct path can mean fewer unnecessary hops.
ZeroLag tests its available routes and picks the best, most direct option to the game server when it measures healthier. That can avoid detours through unrelated cities or transit nodes. It does not modify game files or move browsing, voice chat, streams, or downloads onto the ZeroLag path.

before you connect.
Every feature earns a millisecond.
Auto-routing
Per-game path selection that re-optimizes every 60 seconds based on live telemetry across the backbone.
Hop-by-hop telemetry
See every hop, every latency number, every lost packet. No other consumer tool exposes the route this deeply.
Unflagged handoff
Packets exit from consumer-grade IPs near the server. The game sees a normal connection — no modifications, no flags.
Split-tunneling
Only the game you pick is accelerated. Voice chat, browsers, downloads take their normal path at full speed.
Istanbul launch route
The current public launch is deliberately narrow: one documented network location for Turkish CS2 players.
Jitter smoothing
Real-time packet re-pacing flattens variable latency so your mouse feels connected instead of underwater.
ZeroLag or ExitLag?
See the difference clearly.
Both products optimize the selected game's traffic. ZeroLag is a leaner option with a Turkey-first network and a $1.99 monthly launch price; ExitLag has wider global coverage and extra tools.
Players who noticed, immediately.
“My ping is normally fine, but I'd get occasional packet loss. With ZeroLag my ping dropped from 40-42 down to 34 and the loss disappeared.”
“When I switched ISPs I started running into ping problems. ZeroLag didn't change my ping much, but the game feels smooth and the loss is gone.”
“I was using ExitLag, but once I saw I get the same ping with the home-grown ZeroLag, I cancelled my subscription. The input lag ExitLag added just isn't there with ZeroLag.”
“I used to have a really good connection; with ZeroLag I got that old low ping back. ExitLag's sluggish feel is completely gone — the game is smooth and my ping is low.”
“I don't have a ping problem, but I do get packet loss. On servers where I lose packets I switch on ZeroLag and my loss drops to zero.”
“I'd used ExitLag for years, but I cancelled my subscription. With ZeroLag the game runs smoother and my ping is lower.”
