Hosting a Brick Hill set is a main way to show off your build or scripting capabilities to other players. Nowadays, with the shutdown Brick Hill site API (which was used to make an access to player information¹⁾ ), you can host a set locally²⁾.

So, you have made a set on some unofficial Workshop executable (BrickBuilder³⁾, for example), but you don't have Node Hill installed. Refer to https://brickhill.gitlab.io/open-source/node-hill/.

But, if you have Node Hill fully configured but you wanna host a set locally, you must change the local option to true in start.js script of your root Node Hill folder and only then you can type node .\start.js in terminal⁴⁾.

As it is stated in notes, >October 2017 Host executables require patching just in order to make them work correctly (not as intended, though). Ditto with Pre-October 2017 Host executables (, requires information).
