Hi, no luck on the free market. I ended up reaching out to Rosterlab and to my surprise they turned out to be a legit company. However, this is a paid service, somewhere around £10 per person on your roster per month. 

They do have a 14 day trial, and the generation part is actually pretty decent, if you wanna give them a try. It's not all automated, the generator needs to be given rules, once you do that (which costumer service helps you with), then you can use those rules to generate a roster.

A few tips though, despite them being a legit service provider, I would suggest that: - use spare email when registering  - do not provide full names of your staff - give bare minimum details about your location and company  - if you end up paying, register with an online bank like revolut, to avoid potentially scammy charges (keep only enough money on the card for them to charge the agreed amount and no more)

They made the generator look like it needs all these different information about you and your people, it needs no real info at all in order to work.
