A full 3D aim trainer that runs in your browser — 13 training modes, human-shaped dummies with headshot zones, game-specific FOV and sensitivity presets. None of Kovaak’s Steam overhead.
▶ Open FPSTrain — freeNEW — six playable 2D aim games beside the 3D trainer: gridshot, ms-timed flicks, tracking, switching, reaction and CPS. Instant, free, no Steam.
Most browser aim trainers are 2D canvas games. They train click speed and reaction, but they miss the part that actually matters in modern FPS: tracking a moving 3D human-shaped target with headshot zones. FPSTrain is one of the very few free tools that ships a real 3D environment in the browser.

The Kovaak Gridshot equivalent — classic aim-training target grid for raw speed & precision.
Random-angle targets for flick reaction training. Closest analogue to Kovaak’s Close Long Strafes.
Smooth and chaotic 3D tracking targets — trains the skill that matters most for Apex and Overwatch.
Only headshots count. The most direct rank-lifter for Valorant and CS2 players.
Scenario-style modes that simulate real duel patterns instead of abstract clicking.
For most players, the right setup is: FPSTrain for daily quick 3D warm-up, Kovaak for weekly deep sessions.
For a 2D click-speed warm-up that loads in under a second, try our sister site fpsaim.com. It’s a single HTML page with 5 focused modes — perfect for pre-queue warm-ups on any device.
Yes — 100% free, no account and no download. Kovaak’s costs $9.99 on Steam and needs a ~700 MB Windows install; FPSTrain runs the same kind of 3D drills in a browser tab on any operating system.
Yes, multiple tracking modes with moving human-shaped dummies and headshot zones. This is the part most browser trainers miss — they only do 2D clicking, while tracking is what actually carries Apex and Overwatch performance.
Grid Shot covers Gridshot-style clicking, Flick Shot approximates Close Long Strafes flicking, Smooth Track and Reactive Track stand in for tracking scenarios, and Peek & Fire / Target Switch mimic duel-style routines instead of abstract clicking.
Yes — presets for Valorant, CS2, Fortnite, Apex and Overwatch let you keep the same cm/360 as in-game. See the dedicated Valorant and CS2 pages for full routines.
For daily warm-ups and most aim training, yes. For Voltaic benchmarks, official leaderboards and the 10,000+ community playlists, Kovaak’s is still king — many players use FPSTrain for quick warm-ups and Kovaak’s for weekly deep sessions.
Yes. Because it is browser-based with WebGL, it works on Windows, macOS, Linux and ChromeOS — including machines where you cannot install the Kovaak’s Steam client.
