DemoLens vs SC2 Tools

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.

SC2 Tools analyzes StarCraft II replays, supports build practice, and provides tools for stream production. Its automated analysis detects more than 100 openings and includes 3D replay viewing, opponent dossiers, MMR trends, and map, matchup, macro, and loss analysis. Practice options include a visual and voice Ghost Build coach, custom build rules, Build Roulette, community builds, and 18 replay-powered Arcade modes. Stream Studio offers 30 OBS widgets, seven virtual sets, automatic scene switching, layouts, B-roll, polls, alerts, and clip markers. It combines Twitch, Kick, YouTube, and TikTok chat and supports creator events including follows, subscriptions, gifts, rewards, cheers, and raids. The free plan costs nothing, with all features available and voluntary tips not unlocking anything. The desktop agent uploads replay data and original files to a private account library; Instant Analysis keeps reports in the browser unless games are saved. Windows requires Windows 10 or later and a live StarCraft II installation with a ranked game on disk; macOS and Linux installs are from source.
