Overview

The public GitHub Pages archive offers more than 2,600 professional matches, grouped by series and searchable. It is free, read-only and needs neither an account nor installation, making it a low-friction way to explore existing games. The archive is not a place to upload personal matches: the separate Analyze page parses one demo in the browser using WebAssembly, and the file stays on your machine.

Freezetime converts demos into 16 Hz player-position data, kills, grenades and economy, with hundreds of features precomputed in database tables. That data-led approach supports detailed review beyond simply replaying a round. Self-hosting requires more work: the repository provides the engine, but no match data or database dumps, so users must supply their own demos.

Key features

Replay and analysis

Synchronized 2D replays bring together player health, economy, the kill feed, grenade trajectories, smoke and flash effects. This gives round review useful tactical context, while remaining a 2D presentation rather than a conventional game replay. Analysis tools include opponent reports, predictions, ML Lab, leaderboards, match comparison, heatmaps, ghost rounds, Moments and Pattern Finder. Their breadth will suit players who want to inspect patterns and compare performance, though the full data workflow is more involved than browsing the public archive.

Private demos and local operation

My DB lets users process private demos without changing the main archive, and the server does not keep a copy. Freezetime says its smart features use deterministic statistics, geometry and locally trained models without external AI services. That is a good fit for users who want analysis on their own machine and control over private match files; it is not a hosted private-match library that removes setup and data-management work.

Some capabilities—Presence queries, Scenarios, free-range heatmap windows and cross-match round overlays—are marked self-host only on the public site. Those are reasons to run the studio locally, but they also make self-hosting necessary for users who need those specific tools.

Pricing

Freezetime is free: the Free plan costs 0.00 USD per free, with a public archive, a self-hosted full studio and no per-use cost. The public archive is the simplest option for readers who only need to browse professional matches. The Analyze page offers a way to parse a single personal demo without setting up the studio, but it does not replace the self-hosted environment for its full analysis workflow.

The free plan carries no stated per-use charge, but self-hosting has a practical cost in effort: users must provide demos and database data and operate the system themselves. Freezetime is MIT licensed for use, modification and sharing, with no warranty. The project directs setup questions to GitHub Discussions and bug reports or feature requests to GitHub Issues.

Platforms

Freezetime supports Linux, macOS, web and self-hosted operation, and covers Counter-Strike 2. The public archive and browser-based demo parser serve web users; the full studio is for users prepared to run the system on their own machine. Its stack uses PostgreSQL, ClickHouse, MinIO and NATS JetStream in Docker, alongside Rust, Go, Python and React components, so this is a substantial self-hosted system rather than a lightweight desktop viewer.

Who it's for

Choose Freezetime if you want a free way to study professional CS2 matches, or if you are comfortable providing match data and operating a self-hosted analysis environment. It is less suitable if you want a private demo archive that is ready to use without setup, or analysis for games beyond Counter-Strike 2.

Pros and cons

Pros: The searchable archive of more than 2,600 professional matches is free and requires no account or installation.
Pros: Browser parsing keeps a single demo on the user's machine, while My DB avoids retaining a server copy of private demos.
Pros: Synchronized replays and a wide set of reports and pattern tools give serious match review more depth than replay alone.
Cons: The public archive is read-only, so personal match analysis requires the browser parser or a separate self-hosted setup.
Cons: Self-hosting requires users to supply match data and database dumps, and the underlying system has a multi-service stack.
Cons: Several advanced analysis features are self-host only, making the ready-to-browse archive insufficient for those workflows.

Alternatives

Game Replay Analyzers is the broader category for readers comparing replay-focused tools.

DataCoach is a better fit for players who want coaching output and training plans, with its free monthly plan including 10 replays, 10 chat tokens and progression tracking.
ReplayLabs suits readers looking for a web and API service with metered upload or request plans rather than Freezetime's self-hosted studio.
SC2 Tools is another free option for players who want its features across Linux, macOS, web and Windows; voluntary tips do not unlock extra features.
CS2 Demo Analysis Kit is a free macOS and Windows alternative with an AGPL-3.0-only Studio and MIT-licensed ecosystem packages and Python exporter.
ReplayDojo is a free browser-based replay-analysis option.
CaptureAge is a Windows alternative for readers focused on its supported game, with a free tier and a paid Pro plan.
CS Demo Analyzer is a free open-source CLI for analyzing and exporting CS2 and CS:GO demos, making it a better fit for command-line workflows.
Gamescan is another web option with paid plans that include monthly credits, game modes and clip analysis.

Verdict

Freezetime is an excellent choice for CS2 players who want a free professional-match archive or are equipped to run their own demo-analysis studio. Its combination of synchronized replay, detailed statistical tools and locally handled private demos is compelling. Look elsewhere if you need a turnkey hosted workspace for personal matches or analysis beyond Counter-Strike 2.
