Three Pillars of Intelligent Code Analysis
Token efficiency, code quality metrics, and local semantic search — all exposed as MCP tools that Claude Code can call directly.
Cheaper to Build, Smarter AI Usage
Reduce AI costs by 60-90% with intelligent context retrieval. Only send what matters - not your entire codebase - to AI models.
Comprehensive Analysis & Metrics
Real-time complexity scoring, maintainability index, and technical debt detection. Know exactly which code will break before you ship.
On-Prem Security & Lightning Speed
Your code never leaves your machine. Local semantic search with local embedding model. Zero latency, complete control, HIPAA/SOC2 ready.
Token Efficiency: Dramatically Reduce AI Costs
Tested on SWE-bench problems, Stellarion's intelligent context retrieval delivers massive token savings compared to traditional approaches. By sending only the most relevant code to your AI, you'll see dramatic reductions in both input and output tokens - translating to lower costs and faster responses.
With Stellarion's intelligent context selection, you can achieve 60-90% token reduction - meaning dramatically lower AI costs and faster response times. Only send what matters, not your entire codebase.
Code Quality: Know What to Fix and When
Stop guessing. Our AI-powered quality dashboard shows you the highest-impact improvements ranked by ROI - so you can ship faster without sacrificing quality.

Your code never leaves your machine. AI-powered semantic search, complete refactoring analysis, and dependency mapping - all running locally with zero cloud dependencies.
All analysis runs on-device via a local embedding model. No API calls, no telemetry, no data leaving your network. Drop-in for HIPAA/SOC2 environments where cloud-based tooling is a non-starter.
BGE embeddings + HNSW vector index let you search by intent, not keyword. Query "payment processing" and get ranked matches across TypeScript, Python, Go, Java, Rust, C#, C++, and more — in milliseconds.
Pattern matching operates on the AST, not raw text — so renames and structural rewrites are syntax-safe. Batch operations across hundreds of files with a single MCP tool call.
Per-function complexity grades (A–D) with cyclomatic and cognitive scores. Identify functions above threshold before they become unmaintainable — integrated directly into Claude Code's context.
Persistent semantic graph (RocksDB-backed) tracks import edges, call edges, and transitive dependencies. Get a risk score and full blast radius before touching shared infrastructure code.
BM25 + vector hybrid retrieval surfaces the right code even when naming is inconsistent. Useful when onboarding to a new codebase or navigating a monorepo with thousands of files.
Built for Every Role on Your Team
Different problems, same engine — the tools adapt to what you're trying to understand
Navigating legacy microservices?
Traverse import/call graphs to understand service boundaries. Impact analysis shows transitive dependents before any refactor.
Estimating refactor scope?
Objective complexity grades per file and function. Understand what's grade D before committing sprint capacity to it.
Codebase growing faster than your team?
Detect circular dependencies, unused exports, and high-coupling modules early — before they compound.
Unknown blast radius on every deploy?
Risk scores and transitive dependent lists, generated locally in CI. Block high-risk PRs before they hit production.
Beyond Basic Linting
Static analyzers find syntax errors. We find the code that will break at 3am.
ESLint tells you about semicolons
We tell you about circular dependencies
SonarQube shows complexity scores
We show you WHY it's complex and how to fix it
Copilot generates code
We tell you if that generated code will scale
We understand your entire codebase. Not just the file you're looking at.
