KanjiIQ Documentation¶
Kanji learning platform with multilingual support.¶
KanjiIQ is a Mobile and web-based language learning platform. This is the beta version and we are starting with Japanese Kanji used in the standard JLPT exams, supporting 51 languages through locale detection. Built with Flutter, Dart Frog, and deployed on Kubernetes.
Some of the future features we are working on include: Pronunciation, gamification, live online and on-demand lessons tailored to each level.
Architecture¶
Multi-container pod design with Flutter Web frontend, Dart Frog REST API, and PostgreSQL — all orchestrated by Kubernetes.
51 Languages¶
Intelligent locale-based language selection that automatically shows region-relevant languages to users across 30 pre-configured locales.
Tech Stack¶
Flutter and Dart Frog share the same language, enabling code reuse between frontend and backend. Self-hosted on Hetzner with k3s.
Cloud Native¶
Standard Kubernetes APIs with no vendor lock-in. Ready to migrate to AWS EKS, GCP GKE, or any CNCF-conformant cluster.
