farmOS is the record book, map, and planning board for a working farm, replacing the notebook, the spreadsheet, and the whiteboard with one web app the whole crew can check from the field. The dashboard opens on a map of your land, so you click a field, a barn, or a pasture to reach every record tied to that place. Assets are the things you manage, from fields and animals to equipment and plantings, and Logs are everything that happens to them: seedings, harvests, treatments, movements, and observations, each with dates, notes, and photos. Quantities attach real numbers to those logs, such as kilograms harvested, litres applied, or hours worked, turning daily notes into yields and input costs you can compare across seasons. Quick forms make common entries fast on a phone, and upcoming or late tasks on the dashboard keep pending work from being forgotten. Plans group assets and logs around a purpose such as a grazing rotation or a season of crop production, while reports summarize the records for analysis. Crew members get their own accounts with permissions, records stay private by default, and an API plus add-on modules connect sensors and other farm tools.
