About

Keeper.sh is a calendar syncing tool that helps you stop double-bookings, and increases your organizational capabilities: compatible with Google Calendar, Outlook, Microsoft 365, Apple Calendar, Fastmail, CalDAV and more. It syncs events in realtime, allows you to redact information so you only sync what you want, and helps you connect your calendars to your agents through a convenient MCP server and optional API. If you'd like to share your calendar with the privacy and calendar filters of your choice, you can also generate as many ICS links as you want. Keeper.sh has a convenient managed solution, but for privacy conscious users or technical hobbyists, it is open-source under AGPL-3.0, where you can get all premium features for free.

About

Tandem provides your entire scheduling team the ability to enter everything into one master calendar. Now your entire staff will be on the same page about what teams and groups are doing events in all your facilities. Tandem will automatically notify you when you are about to double book a facility, team or group. Once your events are all scheduled, Tandem can send them directly to your employee's online calendars and keep them updated with emails when events change or are canceled. Tandem will automatically alert you when an event will conflict with another before the event gets scheduled on your calendar. On facility or room bookings, equipment inventory removals, double booking times for specific groups or teams. Tandem provides your account admins the ability to "override conflicts" and book your event. Use Tandem to create your organizations step-by-step approval workflow for any of your buildings or facilities.
