Written by the company

Simulation Baseball is the most advanced baseball simulation game on the web, and the only one built for the way people actually play today. It runs entirely in your browser. Nothing to download, nothing to install, nothing to patch. Open a tab on your laptop, your phone, or your tablet and your franchise is right there, exactly where you left it. We offer a simulation engine that models the game down to the pitch. Every plate appearance, every bullpen move, every defensive alignment resolves against Statcast-grade player ratings and modern, sabermetric-aware logic. Leverage-based bullpen usage, platoon-aware lineups, surplus-value trade math, realistic aging curves, and full prospect development are built into the box, not bolted on as mods. You get the depth of a hardcore front-office simulator with none of the old-school clutter. You run the whole front office. Scout amateurs, draft and develop prospects, work the farm system, navigate free agency, build your 40-man roster, and make the trades that define your contention window. You make the calls. The engine plays them out and streams the results back as play-by-play and full box scores. Simulation Baseball is built for two kinds of players. Solo GMs get a complete single-player franchise against AI opponents that genuinely understand modern baseball. Online leagues get a true multiplayer home for 1 to 30 human managers, with AI covering any open seat and taking over the moment a manager joins or leaves mid-season. Trades execute the instant both sides accept. No FTP shuffle, no file swapping, no commissioner middleware, no "message the commish and wait." Live league chat, live game spectating, in-app dispute resolution, and commissioner-controlled sim schedules (daily, weekly, or real-time) keep every league running on its own terms, with enforced sim-freeze windows so nobody sims during your trade talks. It is mobile friendly from the first pitch. Bring your own universe. Start with a richly generated player world with realistic talent distribution, or import real rosters, custom leagues, and historical eras by CSV. Sign up, spin up a league in about five minutes, and start managing. Simulation Baseball. Your franchise, everywhere.

Been playing this genre since 2003

Been playing this genre since 2003. I've had every OOTP since 2004, have run hundred-year dynasties, I've played every possible version of the game. So when the simulationbaseball.com beta came through, I figured I knew exactly what I was walking into. Wrong. The depth was expected. What actually stopped me was the pitch-level modeling. This thing works off real velocity, movement, and location, then resolves contact into an actual ballistic outcome, exit velo, launch angle, where the ball lands on the field. Pull up a starter after a couple of simmed weeks and it hands you expected stats, xwOBA, spray charts, the kind of thing that normally means exporting to a spreadsheet just to look at. It evaluates arms on that level natively. A browser sim, going there, was not something I saw coming. Twenty-plus years in this hobby and there I sat, grinning like an idiot at a rookie's spray chart. That it runs in a chrome tab and still does this is a little ridiculous. If you care about the guts of how a sim decides what happens on a single pitch, get in the beta.
