Hey Product Hunt 👋 I built Vast after one too many "vibe coded" PRs broke something nobody expected - you ask Cursor or Claude Code to change one file, and three services quietly break because nobody could see the dependency chain. Vast connects to your GitHub repo, builds a dependency graph with tree-sitter, and shows you exactly what a change touches before you commit - cycles, god services, overloaded modules, all of it. It went through a pretty big pivot to get here - started as a 3D architecture visualizer, ended up as a focused impact-analysis tool because that's the part people actually needed on a daily basis. A couple of things worth knowing: - Your source code is never stored, only the dependency graph structure - Free tier covers 1 repo, and early-bird Pro pricing is live for the first 100 users here Would genuinely love your feedback - especially if you're shipping a lot of AI-generated code and have felt this pain yourself. Happy to answer anything in the comments today.
