About Devlens

Devlens turns your React and Next.js codebase into an interactive visual graph, helping you understand architecture, dependencies, and feature flows without digging through files. It’s especially useful for onboarding and PR reviews, where understanding the impact of changes is critical.

What you can do with it

  • Explore unfamiliar codebase architecture as a dependency graph
  • Trace blast radius before merging code changes
  • Review pull requests beyond the diff

Who it's for

Developers onboarding to or reviewing changes in TypeScript, JavaScript, Python, Java, Go, or Rust codebases
