Slido is built for live audience Q&A and polls, but its paid plans are annual-only and audience limits vary by tier. Some Reddit users have asked for an open-source option; another thread expresses frustration with Slido and Mentimeter but gives little detail. The alternatives here focus on event discovery, registration, ticketing, invitations and event programs. None is described in the published material as a direct replacement for Slido’s live interaction tools, so choose based on the work you need to move—not just the name on the invoice.
01Why people leave Slido
Annual-only paid plans
Slido’s paid plans are annual-only, according to the published product summary. That can be a poor fit if you need a shorter commitment.
Audience limits vary by tier
Slido’s audience limits are tiered. If your event size is close to a plan cap, check the current limit before renewing.
Some users want open source
A Reddit thread described a search for an open-source Slido alternative. The Reddit threads we read don’t establish how common that concern is.
02The alternatives, ranked by fit
- Best for event calendars
LumaLumaChoose Luma if your bigger need is publishing event calendars, ticketing and guest tools rather than running Slido-style live Q&A and polls. The pricing page gives it a free plan and a $59 starting price. It also flags a 5% fee and weekly send caps, so check those limits before moving a growing event program.
Trade-off: Event tools, not a listed replacement for live Q&A or polls.
7.2/10from
$59/mofree plan - Best for registration
RSVPifyRSVPifyRSVPify is a closer fit when the job is branded registration, managing guest groups, collecting meal choices or handling check-in. The pricing page shows a free plan and a $24 starting price. It also warns about registration caps and ticket fees, so compare those against your expected attendance and sales before switching from Slido.
Trade-off: Registration and guest controls replace a different part of the workflow.
7.2/10from
$24/mofree plan - Best for public discovery
EventbriteEventbritePick Eventbrite if people need to find local events or you organize free events. Its listing includes a free plan and a $15 starting price, plus public event discovery. That is a different job from Slido’s live audience Q&A and polls; paid-ticket fees can also add cost, so price the full ticket workflow before moving.
Trade-off: Paid-ticket fees can bite, and live interaction is not listed.
5.8/10from
$15/mofree plan - Best for recurring groups
Meetup ProMeetup ProMeetup Pro makes more sense when you manage multiple groups or run frequent events and need unlimited attendees. The pricing page puts it at $55 per group monthly. That is a substantial commitment compared with Slido’s from-$17.50 listing, and Meetup Pro is presented as an event platform, not a live Q&A or polling replacement.
Trade-off: $55 per group monthly; it does not cover Slido’s listed interaction use.
5.8/10from
$55/mo - Best for complex programs
CventCventConsider Cvent if you are replacing more than audience interaction: the pricing page highlights complex event programs, venue sourcing, registration and ROI reporting. Pricing is not published in the listing, and it flags reports of overkill. It may fit a larger event operation, but the available information is not enough to judge cost or whether it replaces Slido’s live tools.
Trade-off: Pricing is not published, and the listing flags possible overkill.
6.2/10from
Custom - Best for digital invitations
GreenvelopeGreenvelopeGreenvelope suits hosts whose priority is digital invitations, RSVP and survey tracking, or several yearly mailings. The pricing page shows a free plan and a $19 starting price. It is not presented as a live Q&A or polling tool, so switching makes sense only if invitations and guest responses—not audience interaction—are the work you need covered.
Trade-off: Invitation and RSVP tools, not a listed live-event interaction suite.
