Imagine this: You’re using a free event management software platform to manage your event. You used it to create an event page for promotions, and you registered attendees with it. But, now it’s two days before the event, and you need to send a reminder email to all your registered attendees—but the software doesn’t offer that feature.

Failing to send a reminder email can result in a lot of no shows to the event, simply because it slipped their minds. Had you evaluated the software more thoroughly before choosing it, this situation could have been avoided.

There are several free and open source solutions on the market. However, finding a tool that meets all your needs requires an evaluation of its features. To help you do that, we have prepared this list of the best free and open source solutions. To be considered for this list, the software had to offer at least the following functionalities:

  • Enable organizers to create an event page or website with details such as location and times.
  • Allow attendees to register for events and/or buy tickets/passes.

Other important event management features include attendee management, barcode/QR scanning, email marketing, and mobile apps. However, these features were not requirements for inclusion in this list.

This article looks at three highly rated free event management software options. See the full list of free event management software solutions here.

What do we mean by “best”? Each of the three tools included in this article has had a minimum user rating of four out of five on Capterra’s software directory in the past year. For more details on how we selected these products, you can review our methodology here.

3 best free and open source event management software

1. Allevents.in

Allevents.in is an event discovery and online ticketing platform that doubles as an event management tool. The platform helps you tap into an existing base of event-goers online and reach audiences more quickly than setting up a web page from scratch would.

In its free service, the tool offers event listing and ticketing, as well as 200 email credits that can be used to send promotional emails to attendees (one email credit = one email).

The tool helps organizers bring their events to local audiences with dozens of city pages—spanning 18 countries—that list events happening in each locale. When users open the platform on a browser or mobile app, they are automatically shown the events in their location; they can also choose to view events in other cities.

Here’s what reviewers on Capterra say about Allevents.in:

Pros Cons
  • Event setup is quick and easy.
  • Integration with various social networks makes it easier to promote and market events.
  • Ability to create discount codes is a much-needed functionality.
  • The user interface could be simplified further to make it easier to navigate.

Cost to upgrade: Cost estimates not provided by the vendor; plans are customizable depending on buyer needs.

Mobile app: Android, iOS

Most suitable for: Organizers of one-time or recurring events that want to reach a mass audience. These can include food festivals, book readings, auto shows, dance festivals, and cultural festivals.

Highly rated by: In 2018 and 2019, all Allevents.in’s reviewers came from small businesses (fewer than 200 employees) spread across a mix of industries, including event services, entertainment, arts and crafts, and music.

2. Eventleaf

Eventleaf is a tool that allows you to create and promote event pages, as well as register attendees and sell tickets. The free version of the tool allows you to register up to 100 attendees per year, regardless of the number of events. It also allows you to build event websites and set up marketing campaigns for events.

While Eventleaf is primarily a cloud-based tool, the vendor also offers a desktop version. The desktop version functions while offline and syncs with the cloud version when connectivity is reestablished.

Here’s what reviewers on Capterra say about Eventleaf:

Pros Cons
  • It has a short learning curve, and it’s easy to navigate.
  • There is a high level of customization in the design and registration requirements when creating an event page.
  • It needs an auto-save functionality on the event creation page.
  • It lacks the ability to adjust the audience when sending out email campaigns or surveys.

Cost to upgrade: There are three paid plans: Basic ($1 per attendee), Professional ($2 per attendee), and Ultimate (custom pricing).

Mobile app: Not available.

Most suitable for: Organizers of one-time or recurring events with a niche audience. These can include trade shows, corporate training events, seminars, networking events, and conferences.

Highly rated by: In 2018 and 2019, 64% of Eventleaf’s reviewers came from small businesses (fewer than 200 employees), 18% from midsize (201 to 1,000 employees), and 18% from large businesses (over 1,000 employees). Reviewers are spread across a mix of industries.

3. Odoo Events

Odoo Events is open source software that offers features for all stages of the event planning process. You can use it to design and set up events pages, organize and schedule events on an event calendar, and manage attendee registrations. You can also use it to promote events via email marketing; integrate with social media, SEO tools, and Google Analytics; and do online and offline ticket sales.

The software integrates with other Odoo applications, such as Website Builder, Blogs, CRM, and Email Marketing. Given the platform’s open source architecture, you’ll need to take the costs of deployment into account. You can choose to host it on-premise if you already have the necessary infrastructure or budget to build it up. Otherwise, you can choose to host it on Odoo’s Cloud Platform for a custom price or with a third-party cloud provider.

Here’s what reviewers on Capterra say about Odoo:

Pros Cons
  • Customizability of the interface.
  • The tool is flexible enough to cater to the diverse needs of different users.
  • Self-service means users have to fix any glitches or errors by themselves.
  • Getting direct support from the vendor or affiliates is possible but can be pricey.

Cost to upgrade: The tool is available for free.

Mobile apps: Not available (Odoo integrates with third-party vendors for event-related apps and app integrations).

Most suitable for: Organizers of recurring events with a mass audience, such as sports leagues, music festivals, and auto shows.

Highly rated by: In 2018 and 2019, 82% of Odoo’s reviewers came from small businesses (fewer than 200 employees), 10% from midsize businesses (201 to 1,000 employees), and 8% from large businesses (over 1,000 employees). Reviewers are spread across a mix of industries, including sports, telecommunications, and marketing and advertising.

Next steps

Selecting event management software can be an overwhelming experience. There are various factors to consider, such as number of attendees, feature requirements, and hosting. Therefore, it is always a good idea to thoroughly explore a few solutions before choosing one.

To help you evaluate event management solutions, here are some important points to keep in mind:

  • Size of events you plan to host: While some free solutions are equipped to handle hundreds and even thousands of attendees, others might cap the attendees at 100. Before you choose a solution, know the size of the crowd you intend to cater to, and choose accordingly.
  • Marketing and promotions needs: Online marketing is an integral part of selling tickets for your events. While some tools let you do various marketing activities within the system, others integrate with third-party tools for marketing automation and promotional activities. Explore marketing-related functions of the tool thoroughly before choosing one.
  • Deployment options: In cloud-based deployment, the vendor is responsible for hosting the solution and taking care of any maintenance. You can choose a plan priced on a per-user per-month or per-attendee basis. On the other hand, with on-premise deployment, the responsibility of hosting and maintaining the solution lies with you. You might need technical expertise to host it. Choose a deployment model that you are technically as well as financially equipped for.
  • Experience of other users: Find out what the users of a tool have to say about it. Watch out for any common problems users are facing and what kind of customer support the tool offers. You can read user reviews on Capterra to learn more.

Please don’t confuse FREE as in FREEDOM, with free as in free of charge when talking about free software.
What matters more is the freedom of use, copy, study or modify that free software enables.

A software may be free of charge, but still locks its users down, limits and mistreats them. Like it is the case with many famous phone/computer operating systems and programs.

Otherwise, thank you for including some freedom respecting software in the article.


Thanks for sharing this information. I like to share a creative app for event
named orquideatech which is specially designed for an arrangement of events. It has a specific capacity, for example, customized profile, alarms, and individual timetable makes you fill inside an encounter advantageous.


Thanks for sharing great information with us. I would like to suggest one of the best online concerts, event and Live theater tickets selling sites. Etickets.ca https://www.etickets.ca/ here you can buy concert tickets with cheap price.


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


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.


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’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.


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 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!


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


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


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

[…] 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/ […]


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.


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.


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.


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.


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.


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.


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


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 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.



Thanks for sharing very useful informative article…


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


Excuse me but none of these are free.



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.


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 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.


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)


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.


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/


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?


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.


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.


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


Your Information on Event management Software was useful


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.


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.



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.


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.
