Imdone is the closest option fitting your requirements, as it saves cards in a Markdown text format with special syntax. You can either have all cards in one text file, or individual files for each card. It's pretty flexible, and development is very active. Source: almost 2 years ago

I work full time as an advising consultant and software engineer, so I really need to automate a lot my work on imdone. For starters, I use imdone to plan and manage releases of imdone. - Source: dev.to / over 2 years ago

I use Obsidian (or, rather, the single top-level directory of markdown files) for my customized GTD process. Essential to me are the Imdone app (https://imdone.io) and the Tasks community plugin. They work well together. Source: over 2 years ago

Aren't you afraid of a potential lawsuit from Linear[1]? Your interface looks like a copy paste. Dont get me wrong, it's amazing what you've build but cloning a well funded startup may not be the best strategy. 1 https://linear.app. - Source: Hacker News / about 1 month ago

My current company is using Basecamp. I don't like it; it feels very disorganized, with work scattered across many message boards, chats, kanban boards, etc. Instead of Agile, it uses Shape Up (https://basecamp.com/shapeup), which has a "no backlog" philosophy (https://basecamp.com/shapeup/2.1-chapter-07#no-backlogs). In this system, I feel like most customer-originated work simply gets ignored and forgotten =/... - Source: Hacker News / about 2 months ago
