Overview
Rallly is an open-source group scheduling and meeting-poll tool. Instead of fixed booking pages, it lets an organizer propose multiple dates/times and have participants vote on their availability, Doodle-style, to converge on the best slot. It is built with Next.js, Prisma and PostgreSQL, and offers both self-hosting and a managed cloud.
Where it falls short of Calendly
- Focused on group availability polling rather than one-on-one booking pages, so it does not replace Calendly's personal booking links.
- No direct calendar-availability checking or two-way calendar sync to auto-block busy times.
- No built-in payment collection or paid-appointment support.
- Requires PostgreSQL and SMTP configuration to self-host; not a single-binary deploy.
We list the gaps honestly so you can decide if the trade-off is worth owning your data.
