Rallly

Rallly is an open-source scheduling and collaboration tool for organizing group meetings and events. It helps friends, colleagues, and teams find the best date and time based on participant availability, cutting down on back-and-forth email.

You create a meeting poll in seconds and share it so participants can respond without logging in. The app is built with Next.js, Prisma, tRPC, and TailwindCSS, and uses a PostgreSQL database.

Rallly is licensed under AGPLv3 or later. It is available as a hosted product at rallly.co, and it can also be self-hosted for those who want to run their own instance.
