Free 3D Aim Lab Alternative

A 3D browser aim trainer that covers every useful Aim Lab scenario — gridshot, spidershot, microshot, reflexshot, linetrace — with no Steam install and no account.

▶ Open FPSTrain — free

Aim Lab is great — but Steam-locked

Aim Lab is legitimately one of the best free aim trainers in existence, partnered with Riot for Valorant scenarios. The problem: it is Steam-locked and ~2 GB. If you are on Mac, Linux, ChromeOS, a locked-down work laptop, or just want to train without launching Steam, Aim Lab is not an option.

FPSTrain is the 3D alternative that runs in the browser tab you already have open.
