Tired of feeling lost in huge codebases? AST Visualizer gives you a deterministic bird’s eye view of your code. Our dependency graph shows which files actually matter, where complexity (aka spaghetti code) hides, and makes spotting circular imports effortless. The maintainability score boils technical debt down to a single number..so you know exactly how bad things are. For vibecoders, AST Visualizer helps keep your LLM from turning your repo into a spaghetti factory

After working extensively with large, complex codebases, we kept seeing the same problems across every team: Onboarding takes ages: New engineers often need weeks or even months before they feel productive. Technical debt is inevitable: Whether you’re a team of senior devs or a solo builder with a trusty LLM, codebases tend to get messier over time. LLMs struggle with large codebases: context limits make it hard for them to give reliable guidance, often leaving you more confused than if you explored the code the old school way. That’s why we built AST Visualizer: to give developers a clear, deterministic view of what’s actually going on in their codebase. Ps. We’re also running an early adopters program: early users get full access to all Pro features for free, in exchange for feedback to help shape the product.

Can it go beyond understanding the codebase to finding security threats as well?
