Codemap

Codemap is a code visualization tool that creates interactive graphs of function calls and dependencies within software codebases. It helps developers understand complex software architecture by mapping out how different parts of a codebase connect and interact. The tool works by parsing your code locally and displaying the relationships between functions, classes, modules, and files as a navigable graph.

What makes Codemap stand out is its local-first approach—it runs entirely on your computer using the Language Server Protocol (the same technology that powers code completion in IDEs) and never uploads your code to remote servers. This ensures complete privacy and security for proprietary codebases. It supports multiple programming languages including TypeScript, JavaScript, Python, Java, Ruby, PHP, Go, and Terraform configurations, making it versatile for different tech stacks.

Codemap is particularly valuable for software developers and engineering teams who need to quickly understand complex codebases, whether they're onboarding new team members, planning refactoring work, or trying to avoid breaking changes in production systems. It's especially useful for visualizing frontend component relationships, backend function dependencies, and Terraform infrastructure configurations, helping engineers make informed decisions about code changes.
