I built a free tool that ranks 84 cities for dating + living abroad — rip my data apart
I got tired of piecing together info from a hundred old threads every time someone asks "Thailand or Colombia?" So I built a comparison tool: 84 cities across SEA, Latin America, Europe, Eastern Europe, and MEA, each scored on 15 factors — female:male ratio (age 20–39), dating app activity, cost of living, English proficiency, safety, visa situation, nightlife, internet, healthcare, and so on.
The main thing: you set the weights. If ratio and cost matter to you and nightlife doesn't, slide them up and down and the whole ranking reorders live. There are one-click presets too — Marriage Minded, Nightlife & Apps, Shoestring Budget, etc. — and your slider setup gets saved in the URL so you can share your exact ranking with someone.
Other stuff in there:
- Visa filter for US passports — "show me only places I can stay 90+ days"
- Budget mode — enter your monthly number, cities get flagged affordable/tight/over
- Which dating apps actually work in each country, including the marriage-oriented ones (the Cupid network, Omiai, etc.) and where the locals-only apps shut foreigners out
- Best months to visit per city, side-by-side comparison of 2–3 cities, interactive map
It's free, no signup, works on your phone: https://foreignly.streamlit.app/
Now the ask: a lot of you actually live in these cities, and I don't. If a score looks wrong — ratio, cost, app activity, whatever — tell me in the comments or through the feedback link in the app. I'd rather get roasted and fix the data than have a pretty tool that's wrong. What cities/factors am I missing?
