Cal

Cal is a software publisher that focuses on open scheduling infrastructure, offering a single flagship product simply named Cal. The application positions itself as a privacy-first alternative to mainstream booking platforms, providing individuals, teams, and enterprises with a self-hostable or cloud-based calendar coordination layer. Typical use cases revolve around eliminating the back-and-forth of meeting arrangement: consultants embed a personal booking page on their websites so clients can self-select available slots, human-resources departments set up multi-round interview workflows that automatically respect panelist time zones, educators create office-hour sign-ups that cap student numbers per session, and healthcare practices route patients to the correct clinician based on service type. Built with developer extensibility in mind, the software exposes APIs and webhooks that let organizations weave scheduling into CRM, payment, video-conferencing, and marketing automation stacks, while end-users still interact through a clean, mobile-responsive interface that supports round-robin assignment, collective meetings, paid bookings, and multi-language confirmations. Cal is available for free on get.nero.com, where the latest Windows build is delivered through trusted package sources such as winget, ensuring users always receive the most recent version and can install it alongside other applications in a single batch operation.
