Show HN: Codemap – A Powerful Code Visualizer

3 pointsby ru6xul6about 1 year ago
I want to share a tool I built, Codemap, that visualizes the function call stack of any codebase as a graph. Without any manual steps, it automatically parses a codebase and renders a high-level graph that engineers can interact with, great for understanding the high-level code flow. Supports many languages (Javascript&#x2F;Typescript, Python, Ruby, Go, Terraform) across major platforms (Mac, Linux, Windows).<p>Most importantly, the Codemap parser runs on your local machine to eliminate any privacy and security concerns, in contrast to other code analysis tools built on cloud with AI&#x2F;LLM. After all, code isn&#x27;t something to be easily shared.<p>I submitted this idea in 2020 when it was still a prototype (HN link: <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=24241997">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=24241997</a>), but a lot has changed since then, most notably: * More language support (Ruby, Go, Terraform). Particularly, it can visualize the entire cloud infrastructure by parsing Terraform code, which was helpful to my team as navigating a large Terraform codebase isn&#x27;t always straightforward. * Supports the file-level graph. I found this most useful for frontend engineers who manage large number of React&#x2F;Vue&#x2F;Angular components because, often with one component per file, the file-graph is essentially the component-graph! * Supports Windows, one of the most asked features. * Supports free use without any account sign-up. That said, there are 2k users with a constant flow of new users.<p>Please let me know what you think. Any feedback is welcomed!
