ballchasing.com vs DemoLens

ballchasing.com analyzes uploaded Rocket League replay files and presents statistics alongside a 3D replay viewer. Its automated analysis covers boost use, positioning, movement, demos, and camera settings. Players can compare population statistics across ranks, seasons, and playlists, or group replays to see per-player, per-team, and per-game results. BakkesMod can upload replays automatically using an API token. Public and link-shared unlisted replays can be downloaded and shared. Free accounts allow 70 uploads per rolling week, with a maximum of 20 in a rolling 24-hour period and a default daily quota of about 10. Regular users' group statistics are limited to about 333 3v3 games or 500 2v2 games. Gold Patron costs $2 a month and allows 350 replays per week, up to 350 per day, and group downloads of up to 50 replays. Switch, PS4, and Xbox users cannot upload replays because those platforms do not provide access to replay files. The site identifies Can't Fly as its creator and maintainer.

DemoLens is a free browser viewer for Counter-Strike 2 match demos, presenting a 2D tactical replay rather than a 3D first-person view. It accepts .dem, .dem.gz, and .dem.zst files and parses them in the browser with WebAssembly, so demo files are not uploaded to DemoLens. Replay controls include a multi-level radar, grenade trajectories, player status, key presses, playback speed, and kill markers. Analysis tools provide grenade lineup pins, movement trails, heatmap-style pins, FOV cones, drawing mode, and kill-feed badges. Scoreboard and economy data, player metrics, percentile comparisons, and an integrity check against professional baselines are included. FACEIT demos add synchronised voice playback, per-player voice timelines with WAV export, and chat translation. The browser extension adds one-click demo opening and player scouting statistics in FACEIT rooms. Desktop Chrome, Edge, or Firefox is required; phones are unsupported. The project says it has no accounts, tracking, analytics cookies, ads, or personal-data collection.
