Codeglance offers a fast and efficient way to familiarize oneself with any codebase. With a single command, gain insights into structure and framework, making onboarding and project evaluation simpler. No installation or configuration is needed—just run and understand.
You clone a repo. You have no idea what it is or how to run it. You spend 15 minutes opening files, reading the README, grepping for entry points.
codeglance fixes that.
npx codeglance
One command. No install. No config. No API keys.
| Question | Answer |
|---|---|
| What framework is this? | Not just "TypeScript project" — "Next.js 14 with Prisma and tRPC" |
| How do I run it? | Run/build/test commands pulled directly from the manifest file |
| Where do I start reading? | Ranked list of files to read first based on naming patterns and depth |
| What tools does it use? | CI, Docker, linting, env files — all detected automatically |
