# CsStrats > The working surface for competitive Counter-Strike 2 teams: a tactics library, a .dem demo viewer with 2D and 3D playback, and a collaborative Strat Builder. Built in Odense, Denmark by IS Digital ApS. CsStrats is a web application used by competitive CS2 teams to prepare for matches and learn from them. Three tools share one room: the **Tactics library** (curated Tier 1 and Tier 2 pro plays by map, updated weekly), the **Demoviewer** (drop a .dem file or a FACEIT URL, get a parsed match with round-by-round playback, kill events, plants, defuses, and utility pops in 2D or 3D), and the **Strat Builder** (a collaborative 2D map tool with per-player timed paths, run and walk speeds, scheduled utility throws for smoke, flash, HE, and molotov, and timeline playback). The primary audience is IGLs, coaches, and managers running competitive CS2 teams globally, from amateur and semi-pro tiers to academy rosters. Serious individual players also use it to analyse their own demos before promotion games. ## Product - [Tactics library](https://csstrats.dk/#tactics): Curated Tier 1 / Tier 2 tactics by map, weekly updates, filter by side, type, map, team, and tags. - [Demoviewer](https://csstrats.dk/#demoviewer): Parsed CS2 demos with 2D and 3D playback, per-round annotations, custom callouts attached to map geometry. - [Strat Builder](https://csstrats.dk/#builder): Collaborative 2D map tool.
