WhenFree is a web based scheduling tool designed to help groups find common availability for meetings or events without requiring participants to create accounts. The service allows a user to generate a unique link and share it with others. Each person who receives the link can enter their name and then drag across a visual grid to indicate the times when they are free. WhenFree then identifies the overlapping availability among all respondents and displays the optimal time slots. The platform has been described as a modern alternative to When2Meet. The primary function of WhenFree is to streamline the process of coordinating group schedules for informal gatherings, professional meetings, or any situation where multiple people need to agree on a time. The tool operates entirely through a web browser, and no registration or login is necessary for either the creator or the respondents. This reduces friction and allows for quick setup and participation. The interface relies on a straightforward grid based layout where users mark their free periods by dragging across the time slots. Typical usage begins with one person creating a new scheduling grid on the WhenFree website. That person then shares the generated link via email, messaging apps, or any other communication channel. Recipients open the link, enter their name, and drag across the grid to indicate their availability. Once all participants have responded, the system automatically consolidates the data and highlights the times when the most people are free. The results are presented in a clear visual format, making it easy to choose a suitable meeting time. WhenFree is hosted at whenfree.org and includes links to help documentation, accessibility information, and terms and privacy policies. The tool is maintained by Avi Klayman, who can be reached at avi@whenfree.org. There are no downloadable applications or account management requirements, making the service accessible from any device with a modern web browser and an internet connection.
