As answered by people managing Braintrust.dev and ValuePair.app.
ValuePair.app's answer:
Next.js with Supabase and PostgreSQL and Capacitor.
ValuePair.app's answer:
There is no profile market place that tries to keep the users inside the app by browsing endless profiles and rate people by their looks. Instead it's all about sharing values. ValuePair asks everyone mandatory questions about their world views and their preferences etc. and then it introduces you to one person at a time.
ValuePair.app's answer:
It's difficult to find people with whom you really get along, that's why it's even more important to ask all the mandatory questions that help people to find out if you actually suit with someone. ValuePair is making this process easy and the core principle will be forever free. There are no ads and no paid features that lock you away from actually using the core principles.
ValuePair.app's answer:
The app is for young adults - 18+ The core audience is in the age range of 20-40
