Assumung you're referring to personal projects.

A couple of projects that are all mostly done, ready to be open sourced:

1. ComfyUI Mobile UI (Self Hosted Web App and Android App) - Originally built for a client in cinema VFX who needed to be able to queue and run existing workflows from anywhere. It's built with Typescript, Tailwind and React. All the existing solutions seemed incomplete or buggy. It includes a custom node that helps expose additional API functions. It doesn't require any additional user steps like exporting and importing workflows etc. It just connects to a server running the custom node, lists all the workflows, and then displays them in an ordered list with all their functionality.
2. ComfyUI Prometheus Exporter (ComfyUI custom node) - For the aforementioned client, a much more expansive Prometheus metric exporter that calculates and exposes over 100 useful metrics, with some Grafana dashboards. Python obviously.
3. IPTV Player (self hosted single user web app) - I tried lots of the existing open source solutions such as Viniplay and Nodecast. I found them all to be buggy and have various intricacies that annoyed me. It's built in Typescript, Tailwind and React again. It's quite basic, with no auth or settings. Just a simple playlist import, playlist editor, favourites, and a web player. The UI needs some polish if i am going to open source it. Undecided yet.

I'm a freelance dev who has been slogging away as the sole developer on a very boring but large website for a big non-tech-industry client for the last year. Have had to deal with lots of ridiculous changes and tweaks, so working on some totally different side projects has been a life saver for my motivation and mental health.
