About this project

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.

What is codeglance?

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.

What you get

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

Three modes

npx codeglance                              # terminal output
npx codeglance --for-ai                     # compact brief for Claude/Cursor/GPT
npx codeglance --markdown --output FILENAME # save as onboarding doc

Works on

Node.js · Python · Go · Rust · C/C++

Detects 130+ frameworks across all five ecosystems.

Honest limitations

Reads manifests and file structure only — not source code
Heuristic, not semantic — "files to read first" uses patterns, not import graph analysis
Java, Ruby, PHP not supported yet
