Yes. pretix, Hi.Events and alf.io sell tickets for events from your own server; see the Eventbrite alternatives page for the full list. ### Is Pretix free? Yes. Pretix is open-source software released under the AGPL-3.0 license, so you can self-host it at no cost. You only pay for the server it runs on, and some projects also offer an optional paid cloud plan. ### Can I run this stack with Docker? 9 of the 14 apps here publish Docker images, including Pretix, Hi.Events and osem, so most of the stack can run side by side with Docker Compose on one server. Size the server for the heaviest app and add off-site backups. ## Related questions - [What is the best open source budget management app?](https://appsgit.com/best/budget-management) - [What is the best open source software for crypto and web3 projects?](https://appsgit.com/best/open-source-software-for-crypto) - [What are the best open source AI tools for crypto and web3 teams?](https://appsgit.com/best/ai-tools-for-crypto) - [What is the best open source software for banks and fintech companies?](https://appsgit.com/best/open-source-software-for-fintech) - [What open source AI tools can banks and fintech companies self-host?](https://appsgit.com/best/ai-for-banking) - [What is the best open source software for hospitals and healthcare?](https://appsgit.com/best/open-source-software-for-hospitals) - [What are the best open source AI tools for hospitals?](https://appsgit.com/best/ai-tools-for-hospitals) - [What is the best open source software for e-commerce and retail?](https://appsgit.com/best/open-source-software-for-ecommerce) ## See also - [All e-commerce apps](https://appsgit.com/categories/e-commerce) - [All booking & scheduling apps](https://appsgit.com/categories/booking-scheduling) - [All polls, surveys & events apps](https://appsgit.com/categories/polls-events) - [All media servers apps](https://appsgit.com/categories/media-servers) - [Open-source alternatives to Eventbrite](https://appsgit.com/alternatives/eventbrite) - [Open-source alternatives to Calendly](https://appsgit.com/alternatives/calendly) - [Open-source alternatives to Typeform](https://appsgit.com/alternatives/typeform) - [Open-source alternatives to Google Forms](https://appsgit.com/alternatives/google-forms) - [Open-source alternatives to SurveyMonkey](https://appsgit.com/alternatives/surveymonkey) - [Open-source alternatives to YouTube](https://appsgit.com/alternatives/youtube) - [Jitsi Meet vs BigBlueButton](https://appsgit.com/compare/jitsi-meet-vs-bigbluebutton) --- Canonical page: https://appsgit.com/best/open-source-software-for-events Source: appsgit (https://appsgit.com), the app store for github.
