Kanbanero for Web

A lightweight, account-free Kanban board app that stores data as plain JSON files, allowing users to sync via Git and edit in text editors. Target users are developers and power users who want full control over their task data without cloud dependency.

The plain-text, local-first productivity movement has real momentum right now, driven by growing distrust of cloud lock-in and the success of tools like Obsidian proving developers will pay for data ownership. The closest substitute is Trello for the Kanban layer, but the more direct competition is actually the combination of Obsidian plugins and raw markdown task managers that this same audience already uses for free. At $500–2k/mo, the revenue band reflects reality: developers who want plain JSON and Git sync are also the most likely to just build this themselves in a weekend, which brutally caps willingness to pay and conversion rates. The single most likely failure is that the addressable audience, while vocal online, is too small and too DIY-inclined to sustain even modest subscription revenue — strong market signal here probably reflects enthusiasm in niche forums, not actual purchase intent.
