Overview

CS Demo Analyzer is a command-line tool and developer API for analyzing and exporting CS2 and CS:GO demos. It suits developers building Counter-Strike data workflows who want an open-source parser route rather than a player-facing coaching service. Its focused scope and multiple integration paths are useful; teams seeking a ready-made analysis interface should look elsewhere.

Key features

The CLI exports demo data as CSV, JSON, or CSDM, making it practical to feed spreadsheets, scripts, or downstream tools. An optional position flag adds entity locations, including players and grenades, when spatial analysis matters; leaving it optional avoids requiring that data for every export.

Users can force a demo source, with supported values including FACEIT, ESEA, ESL, and Valve. That gives developers a way to specify the origin expected by their workflow. The Go API supports analyzing a demo or analyzing and exporting it, while the @akiver/cs-demo-analyzer NPM wrapper brings the Go CLI into Node.js projects with TypeScript types and constants.

The project uses the demoinfocs-golang parser, created by Markus W. and maintained by him and AkiVer. Its MIT license permits use, modification, and distribution subject to the license conditions. GitHub Issues and Discussions provide project support channels. The repository page shows no security advisories, which is not a substitute for a security review by teams evaluating a dependency.

Pricing

CS Demo Analyzer — 0.00 USD per free. The free, open-source CLI analyzes and exports CS2 and CS:GO demo files. There is no paid tier or trial; the value is direct access to the tool and APIs without a subscription. The trade-off is scope: it is a developer-oriented analyzer, not a turnkey coaching product or graphical demo workspace.

Platforms

CS Demo Analyzer supports API use and runs on Linux, macOS, and Windows. The Go API and Node.js wrapper give teams options for integrating analysis into their existing code, while the CLI suits command-line pipelines. It is not presented as a web application.

Who it's for

This is a good fit for developers who need automated analysis and structured extraction from CS2 or CS:GO demos, especially when they want to choose between CSV, JSON, and CSDM output or add position data selectively. Its source selection and language integrations are relevant to teams building their own tooling. Players looking for coaching, visual review, or a self-contained interface should consider a companion or alternative product instead.

The companion CS Demo Manager is the more application-oriented option: it lists demo statistics, grenade finding, heatmaps, VAC tracking, video generation, demo downloads, search, and export. Its export options include XLSX or JSON files and direct SQL access to its database. Those features make it a better direction for users seeking a broader demo-management workflow than the analyzer alone provides.

Pros and cons

Pros: Free and MIT-licensed, with CLI, Go API, and Node.js integration routes; useful for teams choosing an implementation path without committing to a paid service.
Pros: CSV, JSON, and CSDM export, optional entity positions, and selectable demo sources support varied data pipelines.
Cons: Its scope is limited to CS2 and CS:GO demos, so it is not a general game replay analyzer.
Cons: The developer-focused CLI and APIs are a poor fit for users who want coaching or a graphical analysis experience without building around the tool.

Alternatives

Browse Game Replay Analyzers to compare tools across the category. For coaching rather than a developer parser, DataCoach offers a web-based free plan with 10 monthly replays, 10 DataCoach Chat tokens, training plans, core coaching output, and progression tracking; its free trial may also suit a short evaluation.

Gamescan is a web alternative with free access and paid plans starting at 4.99 USD per month for 2,000 credits, three Super Mode games, and clip analysis; choose it when those player-facing capabilities matter more than a CLI/API workflow. my-csmanager Demo Viewer is another web alternative. CARL2 Analysis Tool is a free Windows desktop companion for Rocket League analysis, so it fits a different game and platform.

CS2 Demo Analysis Kit is a free macOS and Windows option with DAK Studio under AGPL-3.0-only and ecosystem packages and a Python exporter under MIT; it is worth considering for teams whose preferred platform or Python exporter aligns with that package set. CS2 Demo Analyzer is a free web alternative. Freezetime offers a free public archive and self-hosted full studio across Linux, macOS, and web, making it a better fit for users who want an archive or studio rather than this CLI/API tool.

Mercurial is a web-based alternative with a free plan limited to one AI Deep Scan per day, own demos only, and two saved Setup Lab profiles; its Plus plan is 5.00 USD per month. Pick it when those AI-assisted web workflows are a better match than building around exported demo data.

Verdict

Choose CS Demo Analyzer if you need a free, open-source way to analyze CS2 or CS:GO demos from a CLI or integrate the work through Go or Node.js. Its main advantage is control over structured exports and implementation; look elsewhere if you need a ready-to-use coaching, web, or visual review experience.
