Open source event registration software

For those of you counting along at home, that was only four event registration software solutions. Our fifth and last software option doesn’t strictly meet our methodology guidelines as it currently doesn’t have any user reviews on Capterra’s directory.

Hi Cary,
You should check out our directory on Event Management Software for an extensive list of options. You can use the filtering tool on the left to narrow down your results, and each software page has a more in-depth look at the software features they provide.
Please let me know if I can help with anything else!


While these look to be nice options what I need is for a small local convention that I can enter people who pre register and if they have purchased any of the other options such as meals or memorabilia and then print their badge. It would also be able to be changed each year to accommodate any changes in what is offered. It would need to track how many people registered, meals sold and so forth with the ability to run reports. Does such software exist?


Hey Nick, Thanks for sharing the great list! Eventdex is also one of the best event registration software, Eventdex is all-in-one event management solution that even offers robust online and onsite registration platform, event app, lead retrieval, matchmaking solution and an attendee check-in app. We charge just a small flat fee $0.75 per ticket. Unlike other ticketing services and we do NOT charge an additional percentage fee. No charge for free tickets. Do check us out if you have a minute: http://bit.ly/2OW4yEY


If you are just planning to list an event online then you can try event registration systems such as https://www.eventry.com. It’s an completely unique and free for promoting an event.


This is a great list. I’d also recommend Picatic as another great option. It’s also completely free to run a free event. https://www.picatic.com/p/tour


If you’re looking for something free and SIMPLE, just for listings? Planaby has a plugin that you can list your events on partner or friend sites really easily – that let’s folks like music acts grow their reach because sometimes other sites have a lot more traffic and potential audience than than the one for your band or local wine shop. Also, planaby has a separate website and even a mobile app where activity seekers can discovery you and your events. https://wordpress.org/plugins/planaby-shows-and-events-widget


Great list. Another popular open source event registration solution for the Joomla CMS that is worthy of mention is Event Registration Pro. We have used it for many of our clients successfully for many years. It is also supported well and has tons of great features. I highly recommend it. You can find it here https://www.joomlashowroom.com/products/event-registration-pro-calendar


I totally agree with Jose Bort. Another thing is that using Open Source is sort of risky because of low security resons. Attendees details are crucial and should be secured at the highest level possible. If everyone is allowed to modify the code of the application it becomes like an open book. Some people will be applying modifications to gather registrations in a better way and others will be looking for ways to break inside and use these registrations for totally different reasons. I am founder of CONREGO – software that is between SaaS and OpenSource – for Event Managers who prefer to keep all data secure on their own server. Do not hesitate to mail me if you want to know more.


Thanks for this resource, Nick. Using free vs. paid registration software ultimately boils down to the needs of an event organiser. While fundamental functions can be enjoyed from free software, there are specific functions that can only be utilised from paid services. A good example of paid functions is ticketing (as mentioned in the article). It’s very convenient to use a registration platform that allows for online ticketing and payments. This may allow for better event turnout since the entire process can be done in a matter of seconds. There are also check-in apps that may be paired with these registration software to significantly reduce headaches associated to these vital activities. If the success of your event depends on the amount of sales you generate, research well to see if any free or paid software can meet your specific needs.


Hi Nick,

Thanks for the writeup on Ticketbud! We’ve found that most people pass on our (competitive) service rate, so we’re effectively free to use for anyone. We also offer a nonprofit reduced rate for charities, fundraisers, and the like. : )

Have a great week!
