flower is a simple kanban board written with React and Redux storing the data using localStorage. Hence no data is transferred to any servers.
yarn and then yarn start. Since the board is using localStorage, you can reload the page and the data will persist.
You can also try it out here: https://ragzter.github.io/flower/
Just a hobby project to practise React and Redux and in fact also because I personally want to use it. I feel like all other alternatives are bloated / cost money.
