I like to sell it as team/site license for large dev team in the future. The traction doesn't seem to be there yet.
Because my burn rate is < $150 per year, I have ~1500 users / month come to the site from pure google search alone.

The ux is ok. A few gigabytes of code db running in a cheapest $5 instance of Digital Ocean.
The app is very simple ~8 mb of standalone binary, no external dependency do any other app/db.
