The company behind the products

Built close to
the problem.

The best starting point isn't a feature list. It's the moment someone says, “There has to be a better way to do this.”

HTML Monitor is the public software home of Fill The Night LLC. We build useful products, put them to work, and let real use tell us what needs to get better.

That means caring about the small things: finding an item without a search party, seeing the next task clearly, or discovering a reason to head out tonight.
