LightSpeed is an open-source network optimizer that routes your game traffic through the fastest path using AI-powered proxy selection. No subscriptions. No data harvesting. Just lower latency.
Three steps. That's it. No accounts, no config files, no BS.
Run the lightweight client before your game. It auto-detects Fortnite, CS2, Dota 2, and more.
Our ML model analyzes latency, jitter, and packet loss across all proxy nodes to find the fastest path in under 1ms.
Your game traffic is transparently rerouted. No packet modification, no anti-cheat issues, just faster packets.
Built-in profiles for the games you play. More coming soon.
Full support for all Fortnite server regions. Compatible with EasyAntiCheat — no modifications to game packets.
Optimized for CS2's tick-sensitive networking. VAC-safe — we only reroute, never modify packets.
Works with all Dota 2 regions including SEA, India, and South America. Valve network compatible.
More games coming: Valorant, Apex Legends, Overwatch 2, League of Legends. Request a game →
Real numbers from our test suite. No cherry-picked results.
End-to-end relay RTT from Bangkok through Vultr SGP proxy. 0% packet loss, 1.2ms jitter.
Full tunnel relay to US West Coast (Vultr LA). Consistent sub-1ms jitter, zero packet loss.
XOR-based Forward Error Correction recovers lost packets with just 25% bandwidth overhead. ExitLag uses 200-300%.
Optional Cloudflare WARP integration routes through NTT backbone, bypassing ISP routing inefficiencies. Free.
Protocol encapsulation adds just 0.162ms. 20-byte header + optional 4-byte FEC extension.
Protocol tests (header, FEC, control), plus E2E relay tests against 2 live proxy nodes.
We're not another ExitLag clone. Here's what makes us different.
Not "free trial" free. Not "freemium" free. Free as in zero dollars forever. You run your own proxy on free-tier cloud VPS credits — no middleman, no subscription, no hidden cost. Ever.
Every line of code is on GitHub. Audit it, fork it, improve it. No black boxes, no mystery binaries, no trust-us-bro security.
Our ML model learns which route is fastest based on real latency data, time of day, and network conditions. Not just "pick the closest server."
We never modify game packets. LightSpeed only changes the route your packets take — the content is untouched. Compatible with EAC, VAC, and Vanguard.
No accounts. No telemetry (unless you opt in). No data harvesting. We don't even know who you are — and we like it that way.
Blazing fast, memory-safe, zero-cost abstractions. The entire stack — client, proxy, protocol — is pure Rust with async Tokio and QUIC.

There is no catch. LightSpeed is self-hosted — you run the proxy software on your own VPS (Vultr gives new accounts $300 free credit, Oracle Cloud has a free tier forever). The software is fully open source. We don't sell your data because we don't collect it. In the future, we plan to offer a managed cloud option for those who don't want to self-host.
No. LightSpeed works like a VPN but only for game traffic. We never modify, inject, or inspect your game packets. We only change the network route they take. This is compatible with EasyAntiCheat (Fortnite), VAC (CS2/Dota 2), and other anti-cheat systems. Route optimization tools like ExitLag have been used for years without bans.
It depends on your location and ISP. If your ISP routes your traffic through suboptimal paths (very common), LightSpeed can cut 10-50ms off your ping. If your ISP already has optimal routing, the improvement may be minimal. The AI model picks the best route — or direct if that's fastest.
Currently: Fortnite, CS2, and Dota 2 have built-in profiles. Any UDP-based game can work with manual configuration. We're adding Valorant, Apex Legends, Overwatch 2, and League of Legends soon.
We don't collect any data by default. No accounts, no registration, no telemetry. If you opt-in to anonymous latency reporting, we collect only aggregate network metrics (ping times, not your identity or game data). All traffic passes through unencrypted to avoid adding overhead — we document this transparently.
You host your own — that's the whole idea. Spin up a $5-6/mo VPS on Vultr (or use Oracle Cloud free tier), run the setup-new-node.sh script in the repo, and point your client at your own IP. It takes about 5 minutes. See infra/README.md for the full guide.
Rust gives us the performance of C/C++ with memory safety guarantees. For a latency-critical network tool that handles thousands of packets per second, we need zero-overhead abstractions. Rust's async ecosystem (Tokio) and QUIC libraries (quinn) are world-class.
We train a Random Forest model on network latency data with 11 features: current latency, historical p50/p95, jitter, packet loss, hop count, time of day, proxy load, and geographic distance. The model predicts which proxy route will be fastest and switches in under 1ms. It achieves R²=0.95 accuracy on our test data.
