Show HN: Paradigm – Interactive Visualizer for Codebases (useparadigm.app)

Hi HN — we built Paradigm: a tool that turns a Python repo into an interactive visualization where you can click any node/edge and jump straight to the exact source.

It generates: - Call graphs (what calls what) - Module dependency graphs - “Processes”: end-to-end execution paths inferred from the call graph, from entrypoints (functions/methods with no callers) down to leaf calls (e.g. cli.main → pipeline.run → loader.load → db.fetch)

Why we built it: With AI-assisted coding it’s easy to lose your mental model of how things work. When an agent makes a large change, you still need to understand what it actually did. Paradigm keeps the architecture visible and tied to the source.

Would love feedback.
