Trellith is a tiny Trello clone PWA pursuing simplicity. It's a task management tool with a board view format, designed for individuals. You can organize your projects into boards like a kanban using lists and cards.
All you need to get started with the app is to just open the URL. There is no need to create any accounts.
The data is only stored in your browser's localStorage, not in the cloud. You can own your data.
Trellith works offline once you open the app. It operates normally even in unstable network conditions.
This is a project aimed at improving frontend and web design skills while creating a practical product.
Since data is stored in localStorage, the main thread gets blocked, and there is a 5MB size limit.
