Both are free. The difference is what you get: two-way match score and circular 3-way swaps at Byt og Flyt — co-op and owner-occupied homes and coordinated moving dates at Rumly.
Rumly.dk is free to use and has no paid tier. Byt og Flyt's basic version is free too. The big difference is functionality: at Byt og Flyt you see the match percentage from both sides, and 3-way swaps are found automatically. Rumly keeps it simpler — and covers co-op and owner-occupied homes as well.
