Which open-source cryptocurrency exchange scripts are best today?

[Michalsteve]

I’m researching open-source cryptocurrency exchange scripts and would appreciate insights from developers or founders who’ve used them in production. Which scripts stand out today for security, performance, and ease of customization? What challenges did you face during setup, scaling, or compliance? I’ve seen some teams consult experts like Beleaf Technologies to review options and architectures through free demos or consultancy, which seems helpful when comparing open-source solutions. A few established clients reportedly chose this approach before development. Interested in real-world experiences and recommendations.
