Moitime is a scheduling coordination service that helps a group of people quickly find a time that works for everyone. Instead of a back and forth chat about availability, one person creates a shared link, and everyone in the group marks the times they are free on a shared calendar-like board organized by date and day of the week. The whole point is to skip the usual round of messages asking who is free when, and let the group see the answer at a glance instead. Each participant marks their available times by clicking or dragging across time slots on the board. As people fill in their availability, the results build into a heatmap, so the group can see at a glance which time slots have the most overlap without needing to compare everyone's answers manually. Darker or more filled-in cells on the board mean more people are free at that time, so the best meeting slot stands out visually rather than needing to be worked out by hand. The service also supports connecting a Google Calendar, which can automatically fill in a person's available times based on when their calendar is already free, saving them from marking it by hand. The project is a live web service, reachable through its own website rather than something you need to install, and the README includes screenshots of the home screen, the scheduling board, and a couple of example boards to show what using it looks like in practice. The README itself is written in Korean and links to a short video walkthrough showing the service in action, alongside places to report bugs or suggest new features. Moitime is released under the MIT License, which is a permissive open source license, and the project also has a separate security policy document describing how to report a vulnerability responsibly. Because it runs as a hosted GitHub Pages site, no setup is needed to use it beyond opening the shared link.
