The megathread mentions Diffusion Toolkit, although this is a Windows-only tool.
There is also Breadboard, however I consider this abandoned and lacks some features like rating/scoring.
My hacky tool and why I want something better
I've been using a hacky Python script to interpret prompts and other PNG Info metadata as tags and inserting them into a booru-like software which lets me search and sort by any of those tags (including a prompt keyword, seed, steps, my own rating scores). This tool was useful in a lot of ways when using tag style prompting, but as I move towards natural language prompts with newer models, a tag-based media software will make it harder to search and to compare prompts between images. Also, my hack was hacky and somewhat manual to use, images wouldn't automatically be imported when generated.
So I'd like to start using a purpose-made tool instead, but I'm struggling to find any other options. I'd rather know if a good tool exists before I start rebuilding my duct-tape conveyor belt.
I helped some guy to make this run on linux

It's very hacky and doesnt cache previous results but it works...
