LightSpeed is a game-traffic routing client that uses machine-learning-based proxy selection in an effort to reduce ping. Its model considers latency, jitter, packet loss, and other network data, choosing a relay route or the direct path if that appears faster. It has built-in profiles for 21 games; other UDP-based games can be set up with manual port configuration. The client finds community-hosted, sponsor-funded relays through a signed registry. Its tunnel uses UDP by default and can switch to TCP on networks that block UDP. Optional Cloudflare WARP integration uses MASQUE. XOR-based forward error correction can recover a lost packet, with 25% bandwidth overhead at the default block size. Downloads are listed for Windows 10/11, macOS 12+, and Linux; macOS builds are command-line clients, while Windows and Linux also have GUI builds. Users can run their own proxy node. The project says results depend on location and ISP, and its latency estimate is not a promise of in-game latency.

Who it is for

LightSpeed may suit players on Windows, macOS, or Linux who want to route game traffic through a selected path. It also offers manual port setup for other UDP-based games and the option to run a proxy node.

What is good

  • Includes built-in profiles for 21 games.
  • Can use the direct path when it is faster.
  • TCP fallback is available when UDP is blocked.
  • Users can run their own proxy node.

What to know first

  • Latency improvement depends on location and ISP.
  • macOS downloads are command-line clients only.
  • The tunnel is unencrypted and game servers see the player's real IP.
  • Telemetry is enabled by default and sent over plaintext HTTP.

Verdict

LightSpeed offers game-only routing with selectable relays, direct-path selection, and several platform downloads. Its own cautions about variable results, unencrypted traffic, and telemetry are important to weigh first.
