Update 1/30/2018: This piece has been updated to reflect software pricing system changes, remove nonexistent systems, and reflect new software names and functionalities.

I love free stuff! That’s why I all troll the aisles of Costco every weekend looking to get my hands on free samples of the crackers and artisan cheese sold by the metric ton.

Free things brighten everyone’s day, whether it’s the snacks at your favorite grocery store or event management software.

I’ve compiled a list of free and open source event management software options containing at least one of the following key features:

  • Event attendee registration form

Bonus list: Pass the fees to attendees

In addition to these free and open source options, there’s software out there that forwards costs on to guests, eliminating the need for user fees. I pulled together a quick list of such systems; most are totally free for events that don’t charge admission, and charge attendee fees for paid events that can be rolled into ticket prices.

Standard features for these systems include event website creation, online registration, payment processing, email communication, social media integration, and analytics. Keep in mind that while these software options are easy-to-use, you’re trading off customization capabilities.

(Software options with no user fees for free events are marked with an asterisk.)

  • Brown Paper Tickets: $0.99 + 3.5% per ticket (includes Brown Paper Tickets’ credit card processing fees; event managers who use their own payment processing get 2.5% back)
  • Eventbee*: $1 to $3 per ticket (depending on features) + plus payment processing fees
  • Eventbrite*: 2.5% of the ticket price + $0.99 per ticket + 3% payment processing fee (only paid if buying through one of Eventbrite’s mobile apps)
  • EventLeaf*: $1 + 3% per ticket charged via third party processor; $1 + 6% per ticket charged via EventLeaf credit card processor
  • Eventzilla*: 1.5% (capped at $4.99) + $0.99 per ticket
  • Picatic: 2.5% +$1 per ticket, as well as 2.9% + $0.30 per credit card transaction
  • PlanetReg*: $0.50 + 2% of the cost of each registration (capped at $9) + processing fees
  • rsvpBOOK: $2.95 to $3.95 per registrant ($1.99 for nonprofits) + processing fees
  • Ticketbud*: $0.99 + 2% per ticket + card processing fees (2.9% for the Ticketbud system)
  • Ticketleap*: 2% + $1 for online sales + 3% credit card processing fee if using Ticketleap Payments (you pay your own processing fees if you use PayPal or Authorize.net); no fee for onsite sales

Bizzabo also provides users with the ability to pass registration costs on to attendees.

Our flexible fees allow organizers to pay the fees themselves, pass them on to attendees, or split fees between themselves and attendees.

OpenConf is a peer-review, conference, and abstract management web application that has been used by thousands of events in over 100 countries. The Community Edition is free to use for events supporting themselves. See http://www.OpenConf.com for more information.

Hi David,

Thanks so much for your comment–I don’t know how I missed Bizzabo, when I read your blog on a regular basis! I’m happy to add it to the list.


Thank you for including Event Track from Jolly Events, Hannah. We also have a full event registration solution now, branded as Eventleaf. There are both offline (desktop) and online versions of the software – and some really powerful features like:
– Register event attendees online or on-site
– Register quickly by scanning driver’s license or business card
– Register attendees for specific seminars or sessions
– Print professional name badges
– Scan and verify badges with barcodes or RFID tags

Oh, and there is a free edition of course.

Your Information on Event management Software was useful

The information was very helpful. Thanks for sharing. One of my companies manages various events, so this might come in handy.

Great article, thanks for posting! Having tried quite a few of the products on this list alone, I found that many were a bit too clunky for the type of work I needed to get done. If you’re looking for something a little lighter, I would recommend checking out RSVPify: https://rsvpify.com/

Though they seem to be more wedding oriented, the functionality extends for any type of event. My only complaint is that the free version only supports 100 responses, but the subscription cost is affordable.

Dryfta is the new kid on the block. It is the free, organiser-friendly event management platform. Use it to capture event data & measure event ROI, sell tickets (no service fees), create event website & native mobile apps, add schedules & let attendees check-in to sessions, design badges & retrieve leads for exhibitors, segment attendees & create email campaigns, share real-time reports with multiple teams, among other things.

Hi, thanks for posting this list. I help to run a group which organises regular social events. We currently have a facebook Group page to create events and send out invitations, and where members can log into the group and see what’s on, as well as post and organise events themselves. There are some members of the group who do not ‘do’ facebook for whatever reason, any suggestions for free & open source event management web-based packages which could replicate these tasks, and would be able to integrate with facebook so that events could be created in facebook and then automatically be published on the event management system?

Hi Jonathan,

Evite seems to have that functionality, but it looks like it’s only one way (Evite to Facebook, not the other way around): http://help.evite.com/customer/portal/articles/381652-for-a-free-invitation-how-do-i-invite-my-facebook-friends-or-post-my-event-on-facebook-

Similarly, Eventsbot seems to do this: http://www.eventsbot.com/blog/new-features-added-on-eventsbotcom-2/

As does Eventleaf: http://www.eventmanagerblog.com/eventleaf-online-event-registration-review/

It looks like Odoo may support this feature in the future through a third party app: https://zapier.com/zapbook/facebook-pages/odoo/

Very informative article. I am still really in need of a system that will work for a ‘sip and paint’ type of business. It needs to allow me to create unique invites to give to hostesses who can then forward to their invitees. Invitees need to be able to register and pay for that specific party. Hostesses need to be able to log in to review their invite list and party progress. I need to be able to create numerous unique party invites at one time, and give the hostesses the unique ‘party codes’ to pass on to their guests so the guests can get more party information and register (pay). I know these exist because I’ve seen them on other sites, but have found the paint and sip market to be filled to the brim with ‘consultants’ who choose not to freely share even a feature without payment. I’ve been searching for quite a while. Any assistance would be appreciated!!! BTW this is NOT a sip and paint business but something similar.

New conference management system from Czech republic univerisites in cooperation with Germany uni is http://www.proconfer.com – very easy, some special features (reviewer’s rating, autosending papers to conferences of same topics,..) and they have free pricing for small conferences (below 100 attendees)

I want to add free video invitations platform: https://inviter.com/. Using this you can manage RSVP’s, how many members attend and also allows to send reminders to your guests. The other features are call to action buttons, calendar integration and also have number of customized templates.

Does anyone have any good options for guest list management? I am with a nonprofit and we do a sitdown gala once a year, in which major sponsors purchase tables. I would like to be able to send them a link for them to input their own Guest lists. Currently they send me their guest lists via email, and someone has to manually input them into a spreadsheet


I have a church camp coming up and I would like to introduce an online registration portal for the participants. I would prefer it if it is open source. I also have the intention of hosting the webpage and database locally from my computer. Please recommend a software for me. Thank you.

Excuse me but none of these are free.

I’m an event manager working for not-for-profit organisations.
I need a affordable events programme that can allow for inputting of excel guests lists into the system to begin with, enable all types of reports, updating on payments, table hosts, seating plans etc, which one would you recommend? Thanks


Thanks for sharing very useful informative article…

Great article! I also wanted to add another tool to the list, http://www.whennow.com. WhenNow is a free online ticketing and registration platform. It’s super easy to use and there are NO buyer fees! They also have social sharing, mobile attendee check-in, and analytics reporting.

As for having some of the lowest transaction fees, there’s a cool price calculator to see how they stack up against other big companies like EventBrite, Ticket Spice, and others.

I would like to suggest one more online event planning service: http://www.partylabz.com. It is mostly focused for such events as birthdays, baby showers, weddings, graduations, house warming, getting together and any other celebrations. Though, any type of event can be created using the service. No registration required to create, manage and RSVP to an event. It is free but has some advanced paid options. I believe it is worthy alternative to services mentioned in articles above.

Great list of free tools. I noticed a few were a bit outdated (ex. 123ContactForm has a new look).

I recently posted a list of the best nonprofit event management software tools that includes a bunch of these free tools and some paid ones which also have a nonprofit discount: http://www.wildapricot.com/blogs/newsblog/2017/01/19/nonprofit-event-management-software-tools

Another one for those in Australia/New Zealand/Asia is http://digitaltickets.net they have various free and ‘pass fees on’ or solutions available for events, camps and groups.

At EventBank (https://www.eventbank.com) we are also supporting a lot of NGOs with our technology so they can run charity events such as balls, seminars or conferences more productively.

Hannah, feel free to add us to this list or reach out if you need more information or testimonials.

I work for a foreign embassy and we will need to manage our guest/attendee list. For security purposes we can not use online servers . Do you know any offline software able to create custom invites ( around 4000) including for each guest a custom qr code with name, organization position) to be fast indentified at check in.
Thanks in advance for your help.

Is there a updated version of this information for 2017? I am seeking a free open source event planning software that will allow minimal cost online ticketing for up to 140, registration, no buyer fee, social sharing, mobile attendee check in and analytics. I am a new startup that hosts events/concerts.

Sorry I noted the above update after my post. However, I am interested in free open source tools since I am with minimal budget as a start up.

Hey there–what about AllSeated? They have a free seating plan software that lets you map out the seating for your event. I am frankly quite surprised not to them here, as they are free and my go-to for event planning. If you haven’t already, definitely check them out.

[…] Here’s an awesome blog post with 11 free event management softwares that you can use for your campus event! https://blog.capterra.com/free-event-management-software/ […]

I expecting Ticketgateway.com in the list. which is known for best customer services and quick refunds.

Good article and Eventdex is also one of best event management software

Nice read! Another freebie: http://www.sci-db.com (Scientific DataBase), scientific events management system.

I have been playing around with the free version of Jotform for an upcoming arts and crafts festival. So far it seems very simple to use. You can create unlimited questions and it also allows for file uploads from registrants. Another positive is that it interfaces with Squarespace, which is the platform that our website is hosted on. The free version does limit you to only 100 submissions per month and a 500 mb storage limit. All in all I am really liking it!

Recently, we heard more and more event organizers complaining that their registration service vendors increased their fees.

Here is interesting article about it: “Why Event Registration Fees are Rising — What can You Do about It?”

I’ve just started using http://www.eventsframe.com for all the events at my school. Found them on Twitter. I think they have a paid option but it’s free for our free events.

Hi I would also like to share here eventsframe.com

Designed to simplify ticket creation and multi event management with comprehensive discount tools, EventsFrame is designed by event organisers for events organisers!

I would like to add another event management and ticketing platform to the list, i.e. Yapsody (https://www.yapsody.com/ticketing/).

Yapsody is a professional event ticketing platform that helps event organizers to create, manage, and sell event tickets online. Yapsody is free for free events.

Also add Eventdex to the list.Its one of the best customized event management software in the event industry.

for more info go through eventdex.com
