https://lipcolourmatch.com - a niche search engine built with a simple Flask app + SQLite
(yes, I do still suck at frontend development, but it has a niche userbase that finds it moderately useful)
I am curious, how do you/did you get it in front of your customers? I havean idea for an ultra niche site, in DIY space, but have no clue how to market it.
Thanks for sharing ...
