Best Slido alternatives for conferences in 2026

We build EVOCA, so it is listed first. The notes on other tools say where they are the better call. Competitor details were last checked in September 2026; plan names move, so confirm them before you sign a contract.

The wider roundup, including quiz and classroom tools, is 7 best Slido alternatives in 2026. The feature-by-feature table is EVOCA vs Slido.

What a conference actually needs

Attendees will not install an app between sessions. Each talk needs its own question list, or the 11:00 track answers questions asked in the room next door. Speakers need the top questions next to the slides, not buried on a laptop they cannot see. And the invoice should match a three-day event if that is all you run.

EVOCA covers that path: phone join, emoji reactions, upvoted Q&A beside the slides, and a star rating plus comment when the speaker ends the session. EVOCA does not include live polls. Setup for a multi-day agenda is the tech conference how-to, and the organizer story is live engagement for tech conferences.

1. 1

   EVOCA

   Best for: Developer conferences that want reactions, Q&A, and a one-event price

   Each talk runs its own live session, so parallel tracks do not share a question list. Attendees join from a phone with a QR code or link. They send emoji reactions and upvote questions; the top unanswered questions sit beside the speaker's slides. When the session ends, they leave a star rating and an optional comment. EVOCA does not include live polls. Events up to 100 attendees are free. A larger conference can pay €49 once for a 7-day window, €29/month on Growth (3 admin users, call for papers), or €89/month billed yearly on Scale.

2. 2

   Slido

   Best for: Conferences already tied to PowerPoint, Webex, or an enterprise contract

   Slido is a mature Q&A product with a long enterprise track record and slide-tool integrations. That maturity is the reason to stay if your venue already depends on it. Our head-to-head lists live emoji reactions, a speaker-facing engagement view, and one-time event pricing as the differences that usually matter for a developer conference. Confirm Slido's current plan names on their site before you budget.

3. 3

   Mentimeter

   Best for: Workshops and keynotes built around visual slide interactions

   Mentimeter is strong when the session is a designed sequence of word clouds and slide interactions. It is a weaker fit when the job is a multi-track schedule, a call for papers, and a Q&A wall per talk. The free tier limits how many questions a presentation can include, so check that cap against a full conference day.

4. 4

   Vevox

   Best for: Anonymous questions in regulated or internal conferences

   Vevox emphasizes anonymous Q&A and enterprise controls. That is a real advantage for an internal or regulated audience. Public developer conferences usually care more about a fast join and a visible reaction wall than about those controls.

5. 5

   AhaSlides

   Best for: Education-style sessions on a tight budget

   AhaSlides covers quizzes and Q&A at accessible prices and is widely used in teaching. Free plans cap participants, so compare that cap with your largest room before you commit a track to it.

How to choose

Pick Slido when the venue contract or the slide integration is the constraint. Pick Mentimeter when the keynote is a sequence of visual prompts. Pick Vevox when anonymity and admin controls outrank a public reaction wall. Pick AhaSlides for a teaching-style session with a small room.

Pick EVOCA when the conference is a set of talks that should take questions and reactions from the phone, then keep a rating after the speaker steps off stage. Current figures are on the pricing page.
