Hey all,
I created a colab notebook for the Flux Gym Lora training UI that uses that Kohya SS sd-scripts as its backbone. Its still a bit slow for training using the colab T4 GPU's but hoping some more advancements will come out in the near future that will speed things up. For now this a free alternative that can get folks started locally if you want to download it and run in a Juypter Notebook.

I provided a video tutorial below as well. Feel free to leave some comments on how we can improve this further.
