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 — freeMost 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.
