AdoptSoft
AdoptSoft is a free and open-source animal shelter system that smaller rescues or fosters can install on Windows/Linux. It tracks animals by name, ID, and intake date, plus medical records or adoption screening statuses. Administrators define custom fields (e.g., breed mixes, special diets). The software supports exporting adoptable animal lists to CSV for uploading to pet listing websites. A minimal volunteer scheduling feature allows signups for feeding, cleaning, or weekend adoption events. With no monthly costs, AdoptSoft suits budget-conscious rescues wanting basic tracking functionalities.
