"Free event registration software": what to actually look for

April 28, 2026 · 8 min read

You've Googled "free event registration software." You're getting back a list of tools that claim to be free, plus a wall of comparison articles that look suspiciously like they were paid for. Before you sign up for any of them, it's worth knowing what "free" actually means in this category — because almost none of these products are free in the way you probably mean.

This is the version of the article we wish someone had written before we built our own tool. It walks through the four flavors of "free," what to look for based on your event, and the three things that quietly determine whether a free tool is actually free for you.

The four kinds of "free" you'll see

1. Free until you do anything useful

The most common pattern. Sign up free, then discover the free tier has a 25-person cap, or doesn't include reminders, or limits you to one active event. The product works fine for the empty-shell version of your event, then asks for $30/month the minute you have actual people.

This isn't dishonest — every SaaS does it — but if you're a PTA volunteer running a single event in the spring, "free with limits" can absolutely be enough. The trick is reading the limits before you've already invested an afternoon configuring the thing.

2. Free for free events, fees on paid events

The Eventbrite model and the Mercurylist model. The signup itself costs nothing; you pay a percentage when money changes hands. This is honest pricing — you only pay when you're collecting revenue — but the percentages vary a lot. We've seen tools charge anywhere from 2% (rare) to 8.95% + per-ticket fees (common).

For comparison: Mercurylist charges 5% on collected payments, with no per-ticket fee. If you don't collect payments, it's genuinely free.

3. Free, but the data isn't yours

A few "free" platforms make their money by owning the relationship with your attendees — they email people about other events, they use the data for marketing, they make it hard to export your contact list. If you're running a community built on relationships, this is the kind of "free" that costs you the most over time. Read the data export policy before you commit.

4. Genuinely free

Google Forms is the canonical example. It's a survey tool that gets pressed into event-signup duty, and for simple cases it's perfectly fine. The reason it's free is because it isn't really an event tool — Google built it for a different purpose and the event use case is incidental. (We wrote a longer comparison of Google Forms vs. dedicated tools if you want the deeper version.)

The three things that actually determine cost

Forget the headline pricing. The actual cost of any "free" event tool comes down to three questions. Answer these honestly about your event and you'll know which tier of which tool is the right fit.

Question 1: Are you collecting money?

If yes, the math gets serious. A 7% fee on a $30 ticket × 50 attendees per event × 12 events a year is $1,260 in fees annually. A 5% fee on the same numbers is $900. The difference between platforms is whatever you'd spend on a decent dinner out, every month.

If no — pure volunteer signups, no payments — almost any free tier will work. Optimize for usability instead.

Question 2: Do you need slots, capacity limits, or a waitlist?

This is the line that separates "form" tools from "event" tools. If your signup is "12 parents, 4 per shift, automatic waitlist when full" — Forms cannot do this. You need a tool that understands per-option capacity. Most free tiers of dedicated event tools include this; survey tools don't, no matter how much you'd like them to.

Question 3: Do you need automatic reminders?

The single most common reason people don't show up to a thing they signed up for is that they forgot. Reminders fix that. If reminders aren't included, you'll either build them yourself (an afternoon of fighting with email integrations) or absorb the no-show rate. Both have a cost. Reminders are usually included on free tiers of real event tools and almost never included on survey tools.

A practical decision tree

What "free" should actually mean

Our take, and the reason we built things the way we did: free should mean free. If you're not collecting money, you shouldn't pay anything — not a monthly fee, not a "premium" gate on basic features like reminders, not your contact list as payment. The product should be useful before it asks anything of you.

When you do start collecting payments, the fee should be predictable and modest enough that you don't lose track of it. A 5% platform fee on top of Stripe's processing means roughly 8% of every dollar goes to fees, which is the actual cost of running a payment platform. Anything materially higher is a markup, not a cost.

Whatever tool you pick, the test is the same: read the limits, do the fee math for your real numbers, and make sure you can leave with your data when you want to. The rest is just feature differences you can figure out in a free trial.
