Facts

Purpose: LightSpeed routes game traffic through a fast path using ML-based proxy selection to reduce ping.shibbityshwab.github.io · 3 Oct 2026
Game support: It has built-in profiles for 21 games, and other UDP-based games can use manual port configuration.shibbityshwab.github.io · 3 Oct 2026
Routing: Its model evaluates latency, jitter, packet loss, and other network data to select a route, or the direct path when that is fastest.shibbityshwab.github.io · 3 Oct 2026
Relays: The client uses a community-hosted, sponsor-funded relay network and verifies a signed registry to discover relays.shibbityshwab.github.io · 3 Oct 2026
Integrations: Optional Cloudflare WARP integration uses the MASQUE protocol and is described as routing through the NTT backbone.shibbityshwab.github.io · 3 Oct 2026
Packet recovery: XOR-based forward error correction can recover a lost packet with 25% bandwidth overhead at the default block size.shibbityshwab.github.io · 3 Oct 2026
Tunnel fallback: The client-to-proxy tunnel defaults to UDP and can switch to TCP on networks that block UDP.shibbityshwab.github.io · 3 Oct 2026
Security: Clients register over a QUIC control plane and use per-packet session tokens; proxy authentication is on by default.shibbityshwab.github.io · 3 Oct 2026
Privacy: Anonymous aggregate telemetry is enabled by default and can be disabled; telemetry is sent over plaintext HTTP to an unauthenticated endpoint.shibbityshwab.github.io · 3 Oct 2026
Traffic protection: The tunnel is unencrypted, game servers see the player's real IP, and relay operators could observe or modify traffic in transit.shibbityshwab.github.io · 3 Oct 2026
Compatibility: LightSpeed says it reroutes without modifying game packets or memory and is designed to work alongside major anti-cheat systems; it does not guarantee bans will never occur.shibbityshwab.github.io · 3 Oct 2026
Performance limit: Ping improvement depends on the player's location and ISP, and the site says its latency estimate is a signal rather than a promise of in-game latency.shibbityshwab.github.io · 3 Oct 2026
Supported systems: Downloads are listed for Windows 10/11, macOS 12+, and Linux; macOS downloads are CLI clients, while Windows and Linux also list GUI builds.shibbityshwab.github.io · 3 Oct 2026
Self-hosting: Users can run their own proxy node, with the site describing setup using a VPS or Oracle Cloud's free tier.shibbityshwab.github.io · 3 Oct 2026
Support: The project links to GitHub Discussions, bug reports, and game requests for community support.shibbityshwab.github.io · 3 Oct 2026
