The Problem

Understanding Code Shouldn't Be This Hard

Developers spend 60% of their time reading and understanding code. Traditional tools fall short when it comes to complex, contextual questions.

Keyword Search Fails

Grep and IDE search can't understand semantic meaning. Searching for 'user authentication' won't find 'login validation'.

Average: 23 minutes per search session

Documentation Gets Outdated

Static docs quickly become stale, missing critical implementation details and recent changes.

58% of docs are outdated

Generic AI Hallucinates

Standard LLMs make up plausible-sounding but incorrect answers. They don't know YOUR codebase.

Up to 40% incorrect answers
The Solution

How RAGly Works

RAGly combines intelligent code parsing, semantic understanding, and retrieval-augmented generation to answer your questions with 100% grounded accuracy.

01

Parse & Chunk

AST-based parsing extracts meaningful code chunks while preserving semantic boundaries and relationships.

Supports 50+ languages
02

Embed & Store

Generate vector embeddings and store in ChromaDB for lightning-fast semantic retrieval.

Sub-100ms queries
03

Retrieve

Semantic search finds the most relevant code chunks for your natural language query.

Context-aware ranking
04

Generate

LLM generates grounded answers using only retrieved context, with citations to source files.

How does the authentication middleware work?

The authentication middleware in src/middleware/auth.py uses JWT tokens to validate requests. Here's how it works:

src/middleware/auth.pyLines 15-28
@middleware
async def auth_middleware(request, call_next):
    token = request.headers.get("Authorization")
    if not token:
        raise HTTPException(401, "Missing token")
    
    payload = jwt.decode(token, SECRET_KEY)
    request.state.user = payload
    return await call_next(request)

Powerful Features

Everything you need to understand and navigate complex codebases efficiently.

Natural Language Queries

Ask questions about your code in plain English. RAGly understands context, intent, and technical nuance.

Source Citations

Every answer includes clickable file paths and line numbers. Verify and explore the actual source.

Multi-Repository Support

Connect multiple repositories and query across your entire codebase ecosystem seamlessly.

AST-Based Chunking

Intelligent parsing preserves code structure and semantic boundaries for superior retrieval accuracy.

Real-Time Indexing

File watcher detects changes and updates the index automatically. Always up-to-date, never stale.

Privacy-First Design

Your code stays on your machine. Use local LLMs for complete air-gapped privacy.

Visual Code Explorer

Browse your indexed codebase visually. See relationships, dependencies, and hot spots.

Query History

Full conversation history with search. Pick up where you left off across sessions.

Enterprise Ready

Frequently Asked Questions

Everything you need to know about RAGly.

Unlike generic AI tools, RAGly is specifically designed for codebase understanding. It indexes YOUR code and provides answers grounded in YOUR actual source files with citations, eliminating hallucinations.

RAGly is privacy-first. All indexing happens locally on your machine. Only when you query, the relevant chunks are sent to the LLM. You can also use local LLMs for complete privacy.

RAGly supports 50+ languages including Python, JavaScript, TypeScript, Java, Go, Rust, C++, Ruby, and more. Our AST-based parsing adapts to each language's syntax.

Initial indexing typically takes 1-5 minutes depending on codebase size. After that, RAGly watches for changes and updates incrementally in real-time.

RAGly works with any Git repository - public or private. It clones locally and indexes without ever exposing your code publicly.
