Best RSVP Tools for Event Registration & Conferences
Compare RSVP tools built for conference organisers, workshop hosts, and training coordinators. We tested 5 options — here's what actually works for collecting attendee info, managing waitlists, and tracking registrations.
Managing registrations for conferences, workshops, or training sessions? You need to collect attendee information reliably, confirm attendance, manage capacity, and ideally send reminders — all without wrestling with complex tools. We've tested 5 RSVP platforms used by event registration organisers and compared them on what actually matters: setup speed, attendee friction, confirmation reliability, waitlist management, and cost.
How we evaluated each tool:
Ease of setup
How quickly can you create a registration page and start collecting attendee information?
Attendee friction
Do attendees need to create an account or download an app to register?
Registration confirmations
Does it send automatic confirmation emails without manual work?
Capacity and waitlist management
Can you set attendance limits, close registration, and manage a waitlist?
Attendee data collection
Can you ask custom questions and export registrant information easily?
Free RSVP built for event registration organisers
Who's In is purpose-built for conference organisers, workshop hosts, and training coordinators. Registrants click a link — no account, no app — and you get instant confirmations, automatic 48-hour reminders, capacity limits, waitlists, and a live dashboard of who's attending. Custom form fields let you collect specific attendee information (dietary needs, experience level, company name) and export registrations in seconds.
Pros
- Registrants don't need an account or app download
- Free for community and corporate organisers
- Instant confirmation emails sent automatically
- Automatic 48-hour reminder reduces no-shows
- Capacity limits and waitlist management built-in
- Custom form fields — collect exactly what you need
- Live attendee dashboard — see registrations as they happen
- One-click export of all attendee data
- Works on any device without friction
Cons
- Focused on RSVP — not a full ticketing platform for paid events
Event ticketing and discovery platform
Eventbrite is the largest event platform. It's powerful for paid conferences and public discoverability, but adds complexity and cost for regular registration management. Processing fees apply on all paid ticket sales, and attendees must create an Eventbrite account to register.
Pros
- Large audience for event discovery
- Integrated payment processing for ticketed events
- Detailed attendee reporting and analytics
- Well-known brand builds attendee trust
Cons
- Transaction fees reduce revenue from paid registrations
- Attendees must create Eventbrite account — adds friction to registration
- Interface feels heavy for simple workshop or training registration
- Limited custom form fields without paid add-ons
- Overkill for smaller conferences and internal training
Community group discovery platform
Meetup helps organisers reach new attendees interested in their topic area. It's built for recurring community groups rather than one-off conferences or workshops. Organisers pay monthly, and attendees must have Meetup accounts to register.
Pros
- Good for discovering new local attendees interested in your topic
- Built for recurring community events
- Has active user base for discovery
Cons
- Monthly cost — not ideal for one-off conferences or workshops
- Attendees need Meetup account — adds registration friction
- Less control over your attendee data and community
- Custom registration questions are limited
- Automatic reminders require Meetup account integration
Free form builder
Google Forms is free and familiar for data collection. But it wasn't designed for event registration. There's no automated confirmation email, no capacity limits, no waitlist, no reminder system, and no attendee-facing experience — just form responses you manage manually.
Pros
- Free
- Familiar to most organisers
- Integrates with Google Sheets for data management
- Can ask unlimited custom questions
Cons
- No automatic confirmation emails to registrants
- No capacity limits or waitlist management
- No automatic reminders — you must email attendees manually
- No live dashboard — you check responses in sheets
- Poor attendee experience — looks and feels like a survey
- Manual work to manage registrations and send followups
- No real-time registration tracking
Social media event management
Facebook Events works for promotion if your attendees are already on Facebook. The "Interested" and "Going" signals are notoriously unreliable as attendance predictors — you typically see 3x more "Interested" responses than actual attendees show up. No capacity management or confirmation system to verify real attendance.
Pros
- Free
- Good reach if your audience uses Facebook actively
- Easy to share and promotes to friend networks
Cons
- Unreliable attendance signals — high no-show rates
- No confirmation system to verify registrations
- No capacity limits or waitlist
- No automatic reminders
- Declining relevance for under-35 audiences
- Can't collect custom attendee information
- No export of attendee data
Our verdict for event registration organisers
If you're running conferences, workshops, training sessions, or seminars, Who's In is the clear choice. It's free, has zero friction for registrants (no account needed), sends instant confirmations and automatic reminders, manages capacity and waitlists, collects custom attendee information, and gives you a live dashboard of registrations. You're set up in 2 minutes. Eventbrite is worth considering if you're running large paid ticketed conferences and want payment processing built-in. For everything else — workshops, training, seminars, webinars, networking events — Who's In removes the friction.
Frequently asked questions
What's the best free RSVP tool for collecting attendee information for conferences and workshops?
Who's In is free and designed specifically for event registration. You can ask custom questions (dietary needs, experience level, company name, etc.), collect attendee information, and export it instantly. Registrants get instant confirmations and automatic reminders — all without creating an account.
How do I reduce no-shows for my workshop or training event?
Three things work: (1) instant confirmation email when someone registers, (2) automatic reminder 48 hours before, and (3) making the RSVP easy so people actually complete it. Who's In does all three automatically. Eventbrite and Meetup require attendees to have accounts, which adds friction and reduces conversions.
Can I set a capacity limit and manage a waitlist for my event registration?
Yes — Who's In lets you set attendance limits, close registration automatically, and manage a waiting list. Eventbrite also has this for paid events. Google Forms and Facebook Events don't have capacity management at all, which means you'll manually track when you hit capacity.
Do I need to manually send confirmation and reminder emails?
No — Who's In sends instant confirmation emails when registrants sign up and automatic reminders 48 hours before your event. Eventbrite and Meetup also automate this. Google Forms doesn't send confirmations, so you'll need to email attendees manually. Facebook Events doesn't reliably reach people at all.
Which tool is best for collecting custom attendee information?
Who's In lets you ask unlimited custom questions and export all attendee data instantly. Google Forms also allows unlimited questions but has no automation or attendee experience. Eventbrite and Meetup allow some custom questions but limit them based on your plan. Facebook Events doesn't collect any structured information.
