I built a comprehensive key-value store management application that combines the simplicity of file-based storage with a modern web interface. It's like having your own lightweight database with a VS Code-like editor built right in.

Demo: https://kv.sekor.eu.org/ (admin@example.com / adminadmin)

Manager: https://github.com/skorotkiewicz/kvstore-manager Client: https://github.com/skorotkiewicz/kvstore-client

The interesting part is how it handles user isolation - each user gets their own directory structure under database/{user-id}/{database-name}/{store-name}.json.

It's perfect for prototyping, small applications, or when you need a simple key-value store without the overhead of Redis or similar.

The frontend includes a dashboard for managing databases/stores, Monaco editor for advanced editing, and comprehensive API docs. Backend is built with Hono.js (faster than Express) with token auth and rate limiting.

What do you think? Would this be useful for your projects?
