DemoLens vs Gamescan

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.

Gamescan is a web tool for analyzing matches, replays, clips, and stats across Fortnite, Valorant, Rocket League, League of Legends, CS2, Call of Duty, and Overwatch 2. After users link an account, Gamescan says match and stat logging begins automatically. Its AI Coach reviews matches or submitted clips and replays, then provides a priority insight with a linked training plan. Plans use match data and set out step-by-step tasks with difficulty and duration. The Analyzer offers Gameplay Breakdowns, Match Reviews, and Progress Reports; performance graphs are included on Pro and higher. Rocket League replay files can receive a Ballchasing-powered breakdown. Fortnite map tools include rotation lines and pins, estimates of loot tier and contest risk, and live, OG, and Reload maps. Social features include friends, creator follows, challenges, a live activity feed, and Shop-item gifting. The Shop lists more than 5,000 cosmetics earned with play credits. Free signup requires no credit card. Free includes 500 credits per month, basic breakdowns, and one-week graphs. Paid plans run from Pro at $4.99 a month to Ultimate at $14.99 a month; higher tiers provide more credits, Super Mode games, deeper analysis, and longer clip uploads.
