Czech Pirate Party would love to use a proven preferential on-line voting system. We generally like Belenios, which is written in OCaml and makes use of the Eliom web framework.
The thing is, we don’t really have the capacity to customize it for our needs and we don’t even know where to start integrating it with our member database and Keycloak single sign-on.
If you’d be willing to help us out, please contact me via Matrix
@mordae:matrix.org or a message here on Lobsters.
