Doodle-style date polls with every answer in one grid
Rallly is a date poll. The organizer suggests a few days or time slots, sends the link around, and each participant ticks the ones that work for them. A single grid holds everyone's answers, readable at a glance. The project pitches itself as an alternative to Doodle and When2meet. You can use the hosted service or run it on your own server; the code is AGPL-3.0 or later.
Cal.com and Easy!Appointments solve a different problem: a booking page lists open slots and each guest takes one. In Rallly, the group votes on options the organizer picked. The comparison of open source scheduling tools puts this kind of poll next to booking pages and service calendars.
Account-free voting and slots in each voter's time zone
- Voting without an account: participants open the link and answer. On rallly.co, the organizer can also create a poll without signing up.
- Time zones: each participant sees the time slots converted to their own time zone.
- Private notes: since v4.12.0, a participant can attach a note to their answer that only the organizer reads.
- Finalizing: the chosen option goes out to participants by email, with an
.icscalendar invite. A connected Google Meet account adds the meeting link, on every plan. - SSO when self-hosted: Google, Microsoft or any OpenID Connect provider, and the
ALLOWED_EMAILSvariable limits sign-up to listed addresses or domains. - Sixteen languages: community translations managed on Crowdin, French and German among them.
Paid licenses past one self-hosted account; SMTP required
Self-hosted, free stops at one account. Since v4.0.0 (May 28, 2025), an instance with several users calls for a license. Licenses are perpetual and cover the whole 4.x series: Plus at $49 for up to 5 users, Organization at $299 for up to 50 (a limited-time price, down from $499), Enterprise from $999. Only registered accounts count; people who vote without one do not. Enforcement runs on the honor system: past the limit, the instance keeps working and shows a banner that links to the licensing page. White labeling is stricter and requires an Enterprise license with the white-label add-on.
On rallly.co, the free plan deletes inactive polls. Hobby caps neither polls nor participants, but it deletes a poll once all its dates are in the past and it has seen no activity for more than 30 days. Pro, at $6 per seat per month billed yearly, keeps polls indefinitely and adds poll duplication, advanced settings, email invites, team spaces, custom branding, the API and webhooks. According to the documentation, only the hosted version serves the API. Microsoft Teams and Webex links also require a Pro subscription.
Self-hosting means a full Docker stack, SMTP included. The install script sets up Postgres, S3 storage (Garage), Traefik for HTTPS and the app; any of them can be swapped for an external service. The documentation asks for at least 2 GB of RAM, ports 80 and 443, a domain name and an SMTP server. Without SMTP, neither sign-in links nor notifications go out. The built-in backup copies the database only, not the garage-data volume that holds uploaded files.
Comments are off by default. Since v4.12.0 (August 3, 2026), the organizer has to turn them on in the poll settings. That release announced comments would be removed; v4.14.0 took the warning out, and no decision has been made.
One main developer, frequent releases. Luke Vella authored 3,453 of the 3,558 commits on the main branch. Thirty-one versions shipped in 2026, up to v4.15.4 on October 6. That release fixes a critical Next.js flaw (server-side code execution, CVSS score 9.5) present since v4.8.0 and exploitable without signing in. For anyone who cannot upgrade right away, the release notes advise blocking /api/og-image-poll at the reverse proxy.
