Programming Language on new sites
Recently launched products built on Haskell
4 of the 19 sites using Haskell are product launches we list individually. The other 15 are new business and personal sites: they count towards the figures above but are not listed here. A watch sends them to you.
Belgium
Watches, exports and the API give you all 19 sites using Haskell, from £15 a month.
Notes
- These figures cover websites that went live since April 2026, not the web as a whole.
- Some products people expect to see here are filed under a related category: Backend Framework.
How this page is made
FirstSited looks at each new website near the day it goes live and records what it was built with. We do not go back later, so these figures describe what sites launch with, not what they run today. A site counts towards Haskell when we detect Haskell on it at that look.
Every share on this page is a proportion of the new sites we were tracking at the time. Sites we found across the wider web count towards the figures, but only product launches are listed by name. How we detect technologies · How we find new sites
