Rallly is an open-source scheduling tool that helps groups find the best date and time to meet without lengthy back-and-forth coordination.
The tool addresses the friction of scheduling by letting organizers create polls with multiple date and time options, then share a link for participants to vote on their availability. Participants need no account to respond—they simply open the link and indicate which times work for them. The tool displays all responses in an availability grid so the organizer can see at a glance which option works best, and includes features like comments for discussion, notifications when people respond, and the ability to finalize and announce the chosen date.
Rallly suits anyone organizing meetings, events, or gatherings who wants a simpler alternative to email chains or calendar tools. It works well for small to medium groups where a quick poll suffices. The tool is available as a hosted cloud version requiring no setup, or as a self-hosted Docker image for those who prefer to run their own instance. The project supports multiple languages through community translation and includes features like email notifications and comment threads to keep discussion centralized.
The project maintains active community engagement through a Discord server and welcomes contributions from developers and translators. The codebase is built on a modern stack including Next.js, Prisma, tRPC, and TailwindCSS, making it accessible for developers familiar with these technologies. Documentation covers both self-hosting setup and configuration options, and the project has established contribution guidelines and a security policy for responsible disclosure.
