OSMSim is a tactics simulator for people who want to try an Online Soccer Manager line-up before the real match. You build two squads, set formations, playing styles, line instructions, marking, the offside trap and the sliders, and watch the match play out minute by minute with the score, stats, scorers and cards.
OSMSim does not use the Online Soccer Manager match engine. Results come from a separate, independent model, so they are estimates and may not match what OSM produces for the same line-up. Use it to compare tactics against each other, not to predict an exact scoreline.
This is an independent, unofficial project with no connection to, endorsement by, or affiliation with Gamebasics B.V. or Online Soccer Manager. All trademarks belong to their owners.
The simulation runs entirely in your browser. No account is needed, and the teams you save stay on this device. They are never uploaded to a server. Shared match links carry everything in the link itself, so those squads never reach a server either. An anonymous visit count is kept so it is possible to tell how many people use the site; nothing else about you is collected, you are not profiled or followed across sites, and no data is ever sold or handed on.
