Tech Stack Detection

argus automatically detects languages, frameworks, libraries, and tools in your project.

Languages

Detected by analyzing file extensions and their prevalence:

• Go - .go files
• JavaScript/TypeScript - .js, .jsx, .ts, .tsx
• Python - .py
• Rust - .rs
• Java - .java
• Ruby - .rb
• And many more...

Frameworks

Web Frameworks

Framework	Detection Method
React	react in dependencies
Vue	vue in dependencies
Angular	@angular/core in dependencies
Next.js	next in dependencies
Express	express in dependencies
FastAPI	fastapi in imports
Django	django in imports
Flask	flask in imports
Gin	github.com/gin-gonic/gin
Echo	github.com/labstack/echo

Testing Frameworks

Framework	Detection Method
Jest	jest in dependencies
Vitest	vitest in dependencies
pytest	pytest in imports
Go testing	testing package imports

Libraries

argus identifies common libraries:

• State management (Redux, Zustand, MobX)
• Data fetching (React Query, SWR, Axios)
• UI components (Material-UI, Chakra, Tailwind)
• ORMs (Prisma, Drizzle, GORM, SQLAlchemy)
• And more...

Tools

Detected from configuration files:

Tool	Config File
ESLint	.eslintrc.*
Prettier	.prettierrc
Docker	Dockerfile
GitHub Actions	.github/workflows/
CircleCI	.circleci/config.yml

AST-Based Detection

For JavaScript/TypeScript and Python, argus uses AST parsing for accurate detection:

// Detects actual imports, not just file patterns
import { useState } from 'react';  // ✓ React detected
const react = 'not a framework';   // ✗ Not detected

This avoids false positives from comments or string literals.
