About Rallly
Rallly is an open source scheduling and collaboration tool built to help groups find the best date and time to meet. Instead of exchanging messages about availability, a person creates a poll with several candidate dates and times, shares the link, and participants vote on the options that work for them.

The project is written in TypeScript and released under the AGPL 3.0 license, with the source hosted publicly and the hosted service available at rallly.co.…
