8 Best Dudle Alternatives for Private Group Polls (2026)
First, a naming note that trips people up: Dudle has been renamed. The old dudle.inf.tu-dresden.de address now redirects to DuD-Poll, hosted at dud-poll.inf.tu-dresden.de by TU Dresden. The tool itself is still running and still free.
Dudle was never trying to be Doodle with a better interface. It came out of an academic privacy group, and its distinguishing feature is access control that minimises how much you have to trust the polling server itself. No email collection, no registration, no analytics, and the source is open so you can host it yourself.
The trade-offs are the ones you would expect from a university research project: the interface is spartan, there is no calendar integration, and there is no company behind it promising it will still be there in five years. Here are 8 Dudle alternatives.
1. Carly
Carly keeps polls private in the way most people actually mean it. Participants can connect Google Calendar or Outlook, and their busy blocks fill the grid automatically, but nobody else sees event titles or attendees. Only free and busy crosses the boundary.
Gray cells are auto-filled from connected calendars. Teal intensity shows group overlap.
No account is required to vote, and the poll page carries no ads or trackers. If a grid is the wrong format for your group, Carly can run the scheduling over email instead and propose times directly. One-on-one meetings get free booking pages.
What makes it different from Dudle: Dudle protects privacy by keeping the server ignorant, which also means it can never help you. Carly pre-fills availability from real calendars while keeping event details private, so you get the accuracy without handing over your schedule contents.
Pricing: Free Zapier-style workflows and scheduling; AI agents from $35/month
2. Framadate
The closest philosophical match. Framasoft is a French non-profit that runs Framadate with no tracking, no cookies, and no account, and publishes the source for self-hosting. Date polls and opinion polls both work.
Polls expire after 180 days by default, with a two-month window to extend before deletion.
Best for: Groups who want Dudle’s privacy stance with a maintained interface and an active non-profit behind it.
Pricing: Free (open source)
3. Rallly
Open source, self-hostable, and considerably better looking than either Dudle or Framadate. Uses the vote-on-candidate-times model. No ads, and voting requires nothing from participants.
Best for: Privacy-minded teams who also want the tool to feel modern.
Pricing: Free (open source)
4. Crab.fit
Open-source availability grid with a live-updating heat map and automatic timezone handling. Anonymous by default, source on GitHub, native Android app.
Best for: Groups who want the When2Meet grid model with open source and real timezone support.
Pricing: Free (open source)
5. Nextcloud Polls
If your organisation already runs Nextcloud, the Polls app gives you date and opinion polls entirely inside infrastructure you control. Nothing leaves your servers, which is the strongest version of the guarantee Dudle approximates.
Best for: Organisations with data sovereignty requirements and existing Nextcloud deployments.
Pricing: Free (open source, self-hosted)
6. When2Meet
No account, no email, no tracking beyond the basics, and an interface that has barely changed in twenty years. Not privacy-engineered the way Dudle is, but it collects almost nothing because it does almost nothing.
Best for: Groups who want minimal data collection through minimal features.
Pricing: Free
7. Xoyondo
Broader feature set than Dudle, with anonymous polls, sign-up sheets, file attachments, and a message board. The free tier shows ads on the poll page, which is a meaningful downgrade if you came to Dudle specifically to avoid third-party scripts. Removing them costs $29 per year.
Best for: Groups who want more poll types and will pay to drop the ads.
Pricing: Free with ads; Premium $29/year
8. LettuceMeet
A clean modern grid with optional Google Calendar overlay. No privacy story to speak of, but it is free, fast, and guests do not need accounts.
Best for: Groups who want ease of use more than data minimisation.
Pricing: Free

Two different definitions of private
Dudle’s model is server-side ignorance: the less the host knows, the less anyone can take. That is the right threat model for activists, researchers, and anyone who does not trust the operator.
It is the wrong trade for most teams, because a server that knows nothing cannot catch the conflict that puts a meeting on top of an existing appointment. Calendar-connected scheduling draws the line somewhere else, sharing free and busy while keeping the contents of your calendar out of the poll entirely. Worth deciding which of those two you actually need before picking a replacement.

See what people say
"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
