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 — freeAim 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.

Direct equivalent — balanced target grid for speed + precision.
Chain-like target pattern for combo flow and rhythmic flicking.
Tiny targets for pixel-perfect aim.
3D moving targets for tracking aim.
Pure flick-reaction training at random angles.
For those, keep Aim Lab. Use FPSTrain for daily warm-up on any device; use Aim Lab at home for deep sessions.
If you want a warm-up that loads in under a second on any device (including phones), our sister site fpsaim.com is a pure 2D aim trainer in a single HTML page.
Yes. No account, no download, no paid tier and no Steam install. It runs in any modern browser tab, so you can warm up on a Mac, Chromebook or locked-down work laptop where Aim Lab will not install.
The core mechanical drills carry over directly: Gridshot maps to Grid Shot, Spidershot to Spider Shot, Microshot to Micro Shot, Linetrace/Strafetrack to the Smooth Track and Reactive Track modes, and Reflexshot to Flick Shot. That covers clicking, tracking and flicking — the three skills that move your rank.
Yes — FPSTrain ships Valorant FOV and sensitivity presets plus recoil patterns for the Vandal and Phantom. See our dedicated Valorant aim trainer page for the full routine.
Yes — any modern browser with WebGL support runs it, including macOS, Linux, ChromeOS and most school or office machines. This is the main reason players use it instead of the Steam-locked Aim Lab client.
Yes, per-game recoil patterns for the AK-47, M4, Vandal, Phantom and more, so you can practise spray control rather than only flat 2D clicking.
If you want official Riot-partnered Valorant rooms, global leaderboards and community workshop scenarios, keep Aim Lab for deep home sessions. Use FPSTrain as the zero-install daily warm-up you can open anywhere in under a second.
