What is it?

Timeful is a scheduling tool for finding a time that works for a group. Organizers create a poll with a date and time range, participants mark when they are available, and the site shows where everyone's availability overlaps. Responses can be marked as available or as "if needed", and a subset of participants can be checked to see when they are free.

The project integrates with Google Calendar, Outlook and Apple calendar so that availability can be pulled from real calendars rather than entered by hand. It supports scheduling across different time zones, email notifications and reminders, and availability groups that track members' calendars over time. Polls can be duplicated, results can be exported as CSV, and responses can be restricted so only the creator sees them.

The codebase uses Vue 2 for the frontend, Go for the backend, MongoDB for storage and TailwindCSS for styling. A plugin API lets developers read and set availability on Timeful events from browser extensions, and the repository includes deployment guides for Docker Compose and NixOS.
