This Python application automates the registration of new Cursor IDE accounts, including browser-based sign-up, email verification code retrieval (via tempmail.plus or IMAP/POP3), and updates of Cursor's local authentication tokens and machine identifiers. It serves as a workaround for Cursor's trial limitations by continuously generating fresh accounts. The architecture is a monolithic script with modular components: a browser manager (DrissionPage), email handler, configuration loader, authentication database updater, and machine ID resetter. The entry point is `cursor_pro_keep_alive.py`, which offers two modes: reset machine code only or full registration flow. The code is functional but not highly polished; it relies on third-party email services and browser automation that may break with Cursor or service changes. The project is explicitly deprecated by the author, who recommends alternative tools like Claude Code.
