Hi HN.I built Kanbanero because I wanted a kanban app without an account or server and with data in a format I could easily read.Each board is a plain JSON file in a folder you pick, so you can back it up with Git and edit it in your text editor.It s a macOS app. Built with Flutter. keyboard-driven, light and dark themes.$8.99 one-time on the Mac App Store. No subscription, no IAP or ads.Happy to answer any questions.
