Who this comparison is for
If you're in the swinging and lifestyle community and deciding which platform to use, this comparison matters, and the answer is more geographic than feature-based. Both platforms serve the same community, with meaningfully different geographic footprints. Understanding where each one has actual users will determine which one is useful to you.
The core difference: geography
Kasidie is a US-origin platform with its strongest user base in North America, the US and Canada. It has some European users but the density is much lower outside North America.
Fab Swingers originated in the UK and dominates the British lifestyle market. It also has meaningful user bases in Ireland, Australia, and parts of Europe. Its North American presence is small.
For most users, this geography point settles the question: use where the users are. Everything below elaborates the comparison for people who have real options in both.

Kasidie in depth
Kasidie launched in the early 2010s and has built a genuine community in the US and Canada. Its strengths are its events directory, which is the most comprehensive listing of North American lifestyle events available on any platform, and its community infrastructure (forums, groups, travel features for connecting at events).
The paid membership requirement for messaging is a real limitation. The free tier lets you create a profile and browse, but any actual connection requires payment. This is a meaningful barrier for people testing the platform, and means the active user pool is self-selected for commitment.
Kasidie's UX has improved in recent years, it went through a period of significant stagnation but has been updated. It's not cutting-edge, but it's functional. The mobile app works adequately.
For North American lifestyle users, Kasidie is the primary platform and the events directory alone justifies the membership. It's less useful outside North America.
Fab Swingers in depth
Fab Swingers (usually called "Fab" within the UK community) is the dominant UK lifestyle platform, not inherited, but earned. It has the largest UK user base of any lifestyle-specific platform, a functional free tier that allows real browsing and messaging, and the most comprehensive UK swinger club and event directory available anywhere.
The free tier is a genuine competitive advantage. Unlike Kasidie, you can send and receive messages on Fab without paying, which significantly lowers the barrier to getting started and keeps the active user pool larger and more diverse.
Fab has real community infrastructure beyond matching: regional forums, a large and active general forum, private party listings (not just club events), and a culture of event and party posting that makes it the primary discovery mechanism for much of the UK lifestyle scene.
Its Australian user base is a secondary strength, Fab has real density in Sydney and Melbourne in particular, making it more useful in Australia than Kasidie.
Which to use
If you're in the US or Canada: Kasidie. The user density, events directory, and community infrastructure in North America are its primary value, and there's no meaningful North American equivalent with the same community depth.
If you're in the UK or Ireland: Fab Swingers. Not a close call, it dominates the British market, and the free tier and events directory make it essential infrastructure for anyone in the UK lifestyle scene.
If you're in Australia: Fab Swingers for Sydney and Melbourne; worth checking both in other cities.
If you're in continental Europe: neither has strong density in most European markets. Feeld is more useful for CNM-adjacent dating; local platforms and in-person community (clubs, events, Facebook groups) are typically more valuable than either Kasidie or Fab.
If you travel between the US and UK regularly: both. They serve different geographic markets and don't replace each other.
