I built todotree to solve a problem I kept running into: TODO lists scale poorly once tasks start depending on each other.

Instead of a flat list or grep output, todotree treats TODOs as nodes in a dependency tree (inspired by Makefiles structure and Markdown format). This makes it easier to see what’s actionable, what’s blocked, and how tasks relate.

Key features: - Tree-based visualization of TODOs and their dependencies

- Automatically highlights actionable tasks (red)

- Supports completed (~ / ~~) tasks, shown in blue

- Multiple output formats: terminal, HTML, Markdown, JSON

- Simple Markdown-based input format

- Fast, standalone CLI tool (written in Rust)

I primarily use it to track technical debt and project planning in Markdown files, but it can also be used to visualize TODOs in any structured task list.

Demo + examples are in the repo: https://github.com/daimh/todotree

I’d really appreciate feedback:

- Is the dependency-tree model useful for TODOs?

- Are there similar tools people prefer?

- What would make this more useful in real projects?

Thanks!
