FootBoss is a free-to-start online football management game that runs in a web browser, with no download required. Players take charge of a club, shape its squad and tactics, simulate matches, manage finances, and build a career season by season. The game begins with a free career at lower-division clubs in Brazil or Spain, where managers can recruit players, develop young talent, and aim for promotion. Along the way, they balance wages and transfers, invest in the stadium and club facilities, and handle interviews and press attention that can affect their reputation and the dressing room.

As a career progresses, players can advance from coach to General Manager, overseeing the broader club project, including recruitment, budgets, and infrastructure. FootBoss offers a free plan with one active career and paid monthly and annual Premium subscriptions. Premium unlocks additional leagues and divisions, major competitions, personal and managerial progression features, and up to three active careers; the annual plan also includes unlimited archiving and early access to updates.
