Event registration looks like a solved problem until you run an event that does not fit the shape the tools assume.
A conference with breakout sessions where capacity is enforced per session. A fundraising gala with table assignments and dietary requirements. A training programme where registration must verify eligibility before accepting payment. A webinar series where one registration covers six dates and attendance tracking matters per date.
The gap between “collect names and emails” and “manage a real event” is where most teams discover their tool was scoped for the former.
Here are eight options, spanning simple registration through full event management, with the boundary between them made explicit.
What to establish before you shortlist?
1. Capacity enforcement, and at what level.
Overall event capacity is easy. Per-session, per-ticket-type, and per-timeslot capacity with waitlisting is where tools separate.
2. Payment handling and what it drags in
. If you take payment on the registration form, PCI DSS obligations follow. The current standard is version 4.0.1 and the previously future-dated requirements have been mandatory since March 2025. Using a hosted payment page shifts more of that burden to the processor.
3. CRM behaviour.
Whether registration creates a Campaign Member against an existing Contact or generates a duplicate Lead is a question worth settling before launch rather than after.
4. What happens after registration.
Confirmations, reminders, changes, cancellations, check-in, and post-event follow-up. Registration is the start of a sequence, and tools that only handle the first step push the rest onto someone’s inbox.
Full event management platforms
1. Cvent
The enterprise standard for complex events, covering venue sourcing, registration, session management, attendee travel, onsite check-in, and reporting at a depth the rest of this list does not attempt.
It is priced and implemented accordingly. Organisations running a handful of events per year almost always find it disproportionate.
Best for: Enterprises running large, complex, recurring events.
2. Bizzabo
Strong on the attendee experience and hybrid or virtual formats, with event apps, networking features, and analytics designed around engagement rather than logistics alone.
Worth evaluating specifically if your events have meaningful digital components. Less compelling for straightforward in-person registration.
Best for: Hybrid and virtual events where engagement matters.
3. Splash
Splash prioritises branded event pages and marketing integration, which suits organisations where events are a marketing channel and design consistency is a real requirement.
Lighter on complex logistics than Cvent. Excellent for a launch party, thinner for a multi-track conference.
Best for: Marketing-led events where brand presentation is central.
Ticketing platforms
4. Eventbrite
The default for public, ticketed events, with discovery, ticketing, and payment handled end to end and no setup cost for free events.
The trade-offs are fees on paid tickets and limited control over the attendee relationship. For public events where discovery is valuable, that exchange is often worth it. For internal or invitation-only events, it rarely is.
Best for: Public paid events benefiting from discovery.
5. RegFox
Registration-focused with a transparent per-registrant fee model that frequently undercuts percentage-based competitors at higher ticket prices, plus a capable builder with conditional logic.
Narrower in scope than the event management platforms. Registration is the product, not a module within a suite.
Best for: Paid events where per-ticket fees materially affect margin.
Form platforms handling registration
6. FormAssembly
Registration as a form rather than as an event product, which is the right frame when the event is one process among many and the data needs to land correctly in your CRM.
Conditional logic handles session selection and eligibility branching, payment connectors handle transactions, and Salesforce writes create Campaign Members against matched Contacts rather than duplicate Leads. As event registration form software its advantage is that the same platform already handles your other intake, with consistent compliance and governance.
The honest limitation: no check-in app, no badge printing, no session capacity dashboard. It registers. It does not manage the event.
Best for: Salesforce organisations where registration data matters more than event tooling.
7. Jotform
Fast, inexpensive, with registration templates and payment integrations that cover simple events without much thought. For a single-track workshop or an internal training day, it is entirely sufficient.
Complexity is where it stops. Multi-session capacity, waitlisting, and sophisticated confirmation sequences are beyond what it does well.
Best for: Simple events on a small budget.
8. Formstack
Registration alongside document generation, which is genuinely useful when the event produces certificates, confirmations, or attendance records that need generating and sending.
Check plan tier coverage before committing, as capability distribution across Formstack’s plans is uneven.
Best for: Events producing per-attendee documents.
The three things that break on event day
Whatever you choose, these are where registration systems fail in public, and all three are configuration decisions rather than product limitations.
1. Capacity that was not really enforced.
Many tools cap total registrations but not per-session selections, so a breakout room with forty seats accepts ninety. Test this specifically before launch by registering past the limit yourself.
2. Confirmation emails in spam.
Registration confirmations are transactional and should send from an authenticated domain. Tools that send from their own infrastructure without proper authentication produce a predictable wave of “I never got a confirmation” emails the week of the event.
3. No self-service changes.
Attendees change their session, their meal, or their mind. If the only path to a change is emailing your team, your team becomes the change management system for the duration of registration. Confirm that respondents can edit their own submissions.
Making the choice
The dividing question is whether you are running an event or collecting registrations.
If you need check-in, badges, session capacity, and onsite operations, buy an event platform. A form builder will handle the first ten percent and leave you improvising the rest at the venue.
If the event is straightforward but the data matters, particularly if it needs to sit correctly in a CRM alongside everything else you know about those people, a form platform is the better purchase and considerably cheaper.
The pattern worth avoiding is buying an event platform for its registration form, then discovering that attendee data lives in a system your team does not use, disconnected from the records that would make it useful three months later.
A reasonable middle path exists for organisations that run one large event and many small ones. Licence the event platform for the flagship, run everything else through the form platform you already own, and accept that the two datasets need reconciling once a year. That is usually cheaper than either standardising everything on the expensive tool or improvising the flagship on the cheap one.
