COUNTER-STRIKE / STREAMING DEMO LABA match, byte by byte.
Stream a .dem or .dem.bz2 file to reveal players, events, and smoke volumes. When parsing finishes, choose a round to load its radar replay on demand. Files are processed on your device in browser workers.

Anatomy of a smoke
0 SMOKES CAPTUREDExplore smoke volumes as the demo is parsed, one recorded frame at a time.
Parse a modern CS2 .dem or .dem.bz2 file using the controls above.
Experimental density reconstruction. Blue: density cells · mint: seeds · coral: rejected cells · gold: detonation. Density is not opacity; bullet holes and HE visual effects are not reconstructed. The radar is a flat reference image.
Waiting for the browser to measure memory. It may wait for garbage collection.
INSIDE THE MATCH
From demo stream to match state.
Player entities drive the radar and statistics. Game events populate the match feed as the worker parses the demo. Scrub the radar history to revisit recent movement, or choose Go live to follow the parser.
Compressed demos are decoded with bzip2-codec before reaching DemoReader; raw .dem files stream directly into the parser. Explore the decompression showcase for byte distributions and throughput. Output is limited to 2 GiB per run.
