CS2 Demo Analysis Kit vs valab

CS2 Demo Analysis Kit includes DAK Studio, a free desktop platform for analyzing Counter-Strike 2 demos locally. It links statistics to the source match, round and tick, with a 2D replay for inspection. The app runs on the user’s machine without an account, upload or server. Its modules cover replay, player profiles, duels and mechanics, utility and economy, tournaments, and coach preparation. The built-in exporter imports .dem files or cs2-demo-format v3 ZIPs and parses them on the computer. Windows and macOS downloads include a DMG, installer and portable ZIP options. The full Windows portable ZIP includes the Cologne Major 2026 event package and map data; the core ZIP contains runtime only. The runtime rejects v2 packages, which must be re-exported with cs2df. DAK Studio is AGPL-3.0-only, while ecosystem packages and the Python shell are MIT licensed. The analysis layer is also consumed by RivalHub and CS2 Insight Agent.

valab is a web service for analyzing VALORANT .vrf replay files. Uploads become browser playback, scouting reports, heatmaps, and statistics based on game data recorded in the replay rather than video estimates or a stats API. The viewer places all ten players on a map and shows their view angles, health, weapons, credits, abilities, and round events. Reports can cover you, teammates, or opponents, using every uploaded match in which a player appears. Regularly queued teammates are grouped automatically, while named stacks can be reviewed as one record. Metrics include opening duels, trades, clutches, headshot rates by gun and range, and round impact. The site checks replay builds against verified versions and flags unrecognized builds. Uploaded match data and reports stay private to the uploading account, with real identities removed before browser delivery. Original replay files are deleted after processing, while processed data remains until removed. A local inspector can read a .vrf entirely in the browser without uploading it.
