FPSAim is a free, browser-based aim trainer for competitive FPS players. It runs in any modern browser, needs zero installation, and was built to fit into the 10–15 minutes you have before a ranked queue — not to replace a full-featured desktop app.
Kovaak and Aim Lab are excellent. They are also 700MB Steam installs that take a long time to launch and park themselves on your drive. If you play on a laptop, a shared PC, a Chromebook, or any machine you do not own, they are not an option. FPSAim started as a weekend project to answer one question: how good can an aim trainer get when it has to live in a single HTML page?
The answer turned out to be: pretty good. Canvas 2D plus Web Audio plus a tight physics loop covers every aim skill that matters — click speed, flick aim, tracking, precision, reaction time, target switching.
FPSAim is an independent project. We play Valorant, CS2, Apex and Overwatch at a mid-to-high level ourselves and use the trainer daily as a warm-up. The site is funded by modest, non-intrusive ads so it can remain free; see our Privacy and Terms for details.
If you want full 3D training with human-shaped dummies, 13 game-specific modes and recoil simulation, try our sister site fpstrain.us — a heavier trainer aimed at serious practice sessions.
