# GridOS > League control for sim racing, run from one dashboard and posted to Discord. Sign-ups, a race calendar with > RSVPs, results and championship standings, stewarding with incident reports and appeals, driver licences > with penalty points, team grids, and a per-driver calendar feed. Free for every league. GridOS is a web dashboard plus a Discord bot for the people who run sim racing leagues. One league lives in one Discord server; the dashboard is where it is run and Discord is where everybody reads it. It is used with F1, Gran Turismo, Assetto Corsa and Assetto Corsa Competizione, iRacing, Le Mans Ultimate, MotoGP, rFactor 2, Forza, EA WRC and others; the games it knows are listed on the front page. Everything a league needs is free and stays free. GridOS Turbo is a bigger version of some of it (longer history, more clips per report, the league's own colours on its posts); nothing a league needs sits behind it. ## What it does - **Sign-ups**: a driver fills in one GridOS profile and applies to a tier. Managers accept or decline, and the driver is told either way. A tier can let drivers name a team of their own, which is created when the sign-up is accepted. - **Calendar and attendance**: each round is posted to Discord with RSVP buttons, the count stays current as people answer, and reminders go out before lights out. Every driver can subscribe to their own races as a calendar feed. - **Results and standings**: results are entered once and posted as a graphic, with intervals to the leader, pole and fastest lap. Championship standings follow, with dropped rounds, sprint points and custom bonuses. - **Stewarding**: a driver reports an incident with footage from Discord or the dashboard. Each report opens a private Discord thread with the drivers and the stewards in it, and anything written there lands on the report itself. Stewards vote, one of them signs the verdict, and the driver has one appeal. - **Licences**: penalty points per driver, from verdicts or written on by hand, with their own expiry. - **Teams**: official grids for F1, F2, MotoGP and WEC, each team with its real badge, or a league's own teams with their own colours, seats, cars and principals. - **Access**: staff roles map to Discord roles, and a role can be pointed at one game so a league running two series keeps its panels apart. ## Pages - [Front page](https://gridos.world/): what it runs, the sims it knows, live usage across every league. - [Discover leagues](https://gridos.world/discover): leagues taking drivers, by sim, each with an invite. - [Privacy policy](https://gridos.world/privacy): what is stored, for how long, and how to have it deleted. - [Terms of service](https://gridos.world/terms) ## Facts worth quoting - GridOS is free for every league. Payment for GridOS Turbo is not built yet; Turbo is given, not sold. - A league needs a Discord server. The bot is invited from the dashboard, and the dashboard signs in with Discord; there is no separate account to make. - Drivers keep one profile across every league they race in: name, in-game name, platforms, country. - GridOS stores no personal data beyond what a league needs to run: Discord ids and names, what was entered about a race, and the footage attached to a report. Clips are deleted on a schedule the operator sets. - It is one person's work, run as a public service, and the source of truth for what it does is this site. ## Contact - Discord: the GridOS league, linked from [the discover page](https://gridos.world/discover). - Suggestions and bug reports: `/gridos suggest` and `/gridos bug` in any server the bot is in, or the feedback form in the dashboard.
