DemoLens vs Mercurial

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.

Mercurial is a web-based Counter-Strike 2 demo analyzer that produces gameplay statistics and probabilistic cheat-detection scores. The maker says every demo receives more than 40 cheat-pattern checks. AI Deep Scan weighs those findings with player history, account credibility, and match context. The analyzer grades counter-strafing shot by shot and measures crosshair placement, utility use, pre-aim, ping, and spray shake. Match Coach gives advice tied to individual rounds, while Form Check reviews form after every five scored games. Setup Lab lets players tag matches with equipment and settings, compare setups, and receive AI suggestions. Demos can come from Valve matchmaking, FACEIT, or community servers. The Free plan analyzes only your own demos and includes one AI Deep Scan daily. Plus costs $5 a month; Ultra costs $10 a month and adds priority support. Results can include false positives and false negatives.
