Building a multi-language platform: How to handle 15 languages as a solo creator

Hey everyone! 👋

I've been working on a gamified platform (ThankJapan) designed to help global users explore Japanese culture and language without requiring a sign-up.

One of the biggest challenges I faced recently was expanding support to 15 different languages as a solo creator. Managing UI text scaling across completely different scripts, handling localization efficiently, and keeping the onboarding friction as low as possible required a lot of trial and error.

For those of you who build global or multi-language products, what tools or strategies do you use to manage localization smoothly without slowing down your shipping speed? I’d love to hear your experiences! 🌍✨
