I'm working part-time on my project https://chartbrew.com

It's an open-source data visualization and reporting platform that I started in 2018, I abandoned in 2019, then resumed working on it more seriously in 2020.

Currently, the platform is doing $1,138 in MRR from then managed hosting service and has made over $11k in revenue so far. It's been growing steadily in the last few months but going through a rough Dec-Jan period at the moment. You can see the open page at https://chartbrew.com/open

Onwards and great job everyone at working to make side projects work for you!
