## What it is
Codecrumbs is a tool for learning, designing, and documenting codebases by placing breadcrumb comments in source code, which are rendered as interactive visual schemes in a browser or desktop app. It supports multiple languages and live updates, helping developers explain how features map to code.

## Use cases
- understand an unknown large codebase faster
- onboard new developers to a project in days
- document how a feature maps to source code
- create interactive visual guides to share on a blog
- plan and design a big refactoring or architectural change
- annotate important places in code with breadcrumbs
- teach a team the architecture of an application

## When to choose
- you need to explore or explain a large or unfamiliar codebase visually
- you want to onboard newcomers with interactive, shareable code guides
- you want lightweight architecture documentation tied directly to source code

## When to avoid
- you need actively maintained tooling - the last release was in 2021 and development has stalled
- you need automated code analysis or flowchart generation without manual annotations
- you require deep IDE integration beyond the optional VS Code extension

## Facets
- artifact type: application
- maturity: maintenance
- function: documentation, developer-tools, gui, cli
- domain: developer-tools, documentation, education
- platform: cross-platform, windows, browser
- tags: code-comprehension, code-visualization, onboarding, architecture-documentation, code-annotations, interactive-guides, nodejs, web-server, macos, linux
