DemoLens vs FN-Tools Replay Analyzer

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.

FN-Tools Replay Analyzer is a web service for analyzing Fortnite replay files and compiling results across matches. Automated analysis displays match outcomes, player placements, eliminations, and party information. You can configure scoring rules and tally scores over multiple matches. Placement modes use replay data, kill-feed estimates, or a corrected combination of those sources. Results can be exported as images, web rankings, JSON, or CSV. The Free plan provides a five-match score tally, three simultaneous web rankings, one entry panel, and analysis of 15 files in a rolling 72-hour period. Pro is priced on request and raises those allowances to 300 matches, 25 simultaneous rankings, 10 entry panels, and 300 files in seven days. Pro users can send score images to Discord and assign Discord roles through FN-Tools BOT and FN-Tools Link. Uploads are limited to one replay at a time. Files are processed server-side and deleted afterward; history remains in browser IndexedDB. Public rankings remain available through their URL for the selected retention period.
