DemoLens vs Freezetime

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.

Freezetime is a free, self-hosted analysis platform for Counter-Strike 2 demos. Its public archive is a read-only site with more than 2,600 professional matches, searchable and grouped by series, and needs no installation or account. For a personal demo, the Analyze page parses one file in the browser using WebAssembly, so the file stays on the user's machine. Processing produces 16 Hz player positions along with kills, grenades, and economy data. Synchronized 2D replays show player health, economy, kill feed, grenade trajectories, smoke, and flash effects. Analysis tools include opponent reports, predictions, ML Lab, leaderboards, match comparison, heatmaps, ghost rounds, Moments, and Pattern Finder. My DB can process private demos without the server keeping a copy. Self-hosting unlocks features marked self-host only, but users must supply their own demos because the repository contains no match data or database dumps. The project says smart features use deterministic methods and locally trained models rather than external AI services. Freezetime is MIT licensed, with no warranty.
