Last updated 2026-08-26 · benchmark measured 2026-11-07 — deterministic & reproducible
Vast analyzes GitHub repositories to map architecture and flag code change risks.
Vast at a glance
Vast connects to a GitHub repository and generates a risk report that maps file dependencies and flags issues like cyclic dependencies or risky changes, for development teams working with AI-generated code.
Good for
- Teams reviewing code generated by AI tools like Cursor, Copilot, or Claude who need to see what changed and what it affects
- Engineering managers and code reviewers who want a plain-English summary of a scan-to-scan diff
- Developers who want to spot cyclic dependencies, god files, and risky exported function changes before release
Pricing
Free: $0/mo, 1 repo, basic analysis, 10 explanations/mo. Pro: $9/mo, unlimited repos, full analysis, team sharing. Yearly: 20% off.
Questions people ask
What does Vast do with my code?
Vast connects to your GitHub repository, reads its structure, and produces a risk report showing file dependencies and the impact of recent changes. It only reads the structure and never stores your code.
What kinds of issues does Vast detect?
It uses AST-based analysis to flag things like cyclic dependencies, god files (services with too many responsibilities), isolated nodes, and risky exported function signature changes.
Does Vast work with any codebase?
Vast works with any GitHub repository and shows logos for Python, TypeScript, Go, Docker, and Kubernetes; OpenAPI support is on the roadmap.
Can I use Vast for free?
Yes, the Free plan covers one repository with basic Impact Analysis and Risk Detection, 10 change explanations per month, and the last 5 scans in the timeline.
How does Vast help me use AI coding tools like Cursor or Copilot?
Vast provides a copy-ready risk and impact summary that you can paste into Cursor, Copilot, or Claude so the AI tool can fix the fragile part.
