Description

Keeper.sh is an innovative calendar synchronization tool designed to eliminate double bookings while enhancing your ability to stay organized; it works seamlessly with platforms like Google Calendar, Outlook, Microsoft 365, Apple Calendar, Fastmail, CalDAV, and others. This tool syncs events in real-time and offers the ability to redact sensitive information, ensuring you only share what you wish, while also enabling connections to your agents via a user-friendly MCP server and an optional API. Additionally, users can generate an unlimited number of ICS links, allowing for customized calendar sharing with selected privacy and filtering options. For those who prefer a hands-off approach, Keeper.sh provides a managed solution, but it also caters to privacy-focused individuals and tech enthusiasts by being open-source under the AGPL-3.0 license, granting access to all premium features at no cost. This dual offering ensures that users can choose the level of control and privacy that best suits their needs.
