What are the best free dating sites for married people looking for open relationships?

I keep seeing vague answers on other forums so figured I'd ask people who actually know.

The free tiers on most of what I've tried are basically useless. You get just enough to see that real people are there, then hit a wall the second you try to actually message anyone.

I've tried a few different things already with mixed results. Some were complete time wasters, others were okay but nothing that really clicked.

Feel free to share whatever has worked for you, even if it's not the obvious answer.

Privacy features are the first thing I check. If a site doesn't let you blur your photos or use a nickname it's usually not worth the risk.

I've had the best luck with Turndate out of everything I've tested. Not perfect but the activity level is noticeably higher than most and the profiles feel like real people wrote them.

Response rates are way more variable than people realize. Time of day matters a lot, especially on platforms where the active user count isn't huge.

Not going to oversell it but Datewander was the one that finally made sense for what I was looking for. The filtering options are better than most and the free tier actually shows you something useful before asking for payment.

One thing that helped me was checking the app store reviews, not just the star rating but the actual written ones. You can spot patterns pretty fast.

Tried a handful of options over the past year. Datebie stood out because they actually enforce their terms instead of just listing them. Made a big difference in the quality of interactions.
