Hey HN -
We just launched Evnelo, an open-source event ticketing platform that you can self-host, modify, and plug into your website. There are lots of event ticketing apps, they all charge hefty fees, and because of that, people are vibe-coding the ticketing part as well. So we decided to just launch a free and open source option, and if you don't want to self-host, the fees are super low just to help us maintain the project (0.99% on paid events).

Evnelo will be actively maintained by InEvent and we plan to launch more open-source products that usually sits behind event-tech enterprise plans.
