How to upload a CS2 demo and get match analysis

A CS2 demo contains the decisions behind a match: positions, deaths, grenades, bomb events, money, weapons and timings. Uploading it to CS2 Browser Lab turns that raw file into a broader browser review and practice workspace.

Upload or import

Open CS2 Browser Lab, go to Demos, then upload a CS2 .dem file. If share-code import is configured on the server, you can paste a supported CS2 share code instead. The parser builds the timeline, player snapshots, deaths, utility and replay moments needed for analysis.

If you are new, start with a single close loss rather than a highlight match. Close losses usually reveal clearer rotation, utility and spacing mistakes.

Use the review panel

The review panel organizes the match into summary, rounds, events and utility. Use it like a checklist:

Find repeatable mistakes

Do not review every second with equal attention. Focus on deaths after advantage, late utility, bomb-site entries, post-plant spacing and retakes. These patterns are easier to improve than one-off aim misses.

When a death matters, move it into the replay workflow. Replay moments make the mistake active: you can preview the situation, replay it, and test whether a different route, timing or fight choice works better.

Free users can replay one moment per demo. PRO unlocks every replay moment, which is the fastest path from analysis to practice.

Share with a team

For team review, use screenshots, share links and map inspection. A clean viewpoint is often easier to discuss than a full VOD. PRO includes screenshot and share-link tools, making it easier to point teammates at the same round, angle or utility setup.
