CS2 Demo Analyzer vs DemoLens

CS2 Demo Analyzer is a free web tool on JumpThrow.gg for turning Counter-Strike 2 demo files into match reviews. Upload a standard.dem file to see match statistics, round details, utility data, player positions, and a 2D replay. Ratings are calculated in an HLTV style from raw demo data across every round. The event log covers actions such as kills, trades, plants, and utility throws; positional data supports heatmaps and replay views. Demos can come from any source, including Premier games, scrims, and matchmaking. You can start without an account. A free account adds connected FACEIT and Premier accounts, automatic Premier imports, and saved match reviews. The listed plan costs nothing, with no subscription currently offered. The service receives data from Steam and FACEIT and supports connecting those platforms for its features. Demo archives are retained while needed to verify, reproduce, or provide analysis, subject to valid deletion or objection requests and legal exceptions. Users must be at least 18 to create an account, connect a platform, or upload a demo.

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.
