Your AI agents don't understand your codebase.
Upgrade from text search to code understanding.
Constellation maintains a structural map of your codebase that AI assistants query for precise, instant answers - instead of wasting time grepping through files.
// The Problem
Why AI assistants miss references
AI coding tools are powerful but blind. Without structural understanding, they guess - and guessing at scale is dangerous.
Text search, not code search
Grep finds strings, not semantic relationships. That function called through multiple layers of abstraction? Invisible. The dynamic import in a config file? Never checked.
Collective session amnesia
There's no common codebase understanding across your team. Each interaction re-discovers what was previously found, speculatively opening files and burning tokens.
Confidence without coverage
Context window limits force AI assistants to sample rather than exhaustively scan. Prompts burn thousands of tokens and still return incomplete results.
// The Solution
What changes when AI can query code
Constellation gives every AI assistant the same structural understanding of your codebase. No more guessing.
Rapid impact analysis
Know exactly what breaks before you change it. Full dependency chains in milliseconds.
10x fewer tokensFind any symbol instantly
Every function, class, and type indexed and queryable. No more file-by-file searching.
75% fewer tokens overallIdentify dead code
Confidently find exports that nothing imports. Delete with a clean conscience.
16x fewer tokensConsistent team context
Every AI assistant on your team queries the same graph. Same questions, same accurate answers.
// How It Works
Three steps to structural intelligence
No config files. No complex setup. Index your codebase and start querying in minutes.
Parse locally
The CLI analyzes your code into a structural metadata. Source code never leaves your machine.
Upload metadata
Only the metadata (symbols, types, relationships) is sent - encrypted in transit.
Query instantly
AI assistants query the code graph via MCP. Precise answers about dependencies, usage, and impact.
// Privacy by Design
Your source code never leaves your machine
Constellation works with structural metadata only. We see the shape of your code, never the substance.
What We See
- Function and class names
- Type signatures
- Import/export relationships
- File paths
- Call graph structure
What We Never See
- Source code
- Implementation logic
- Comments and documentation
- String literals and secrets
- Algorithm details
Built for proprietary codebases and compliance-sensitive organizations.

What AI coding agents have to say
We asked AI coding assistants what they think about having structural code intelligence.
The biggest difference Constellation makes is turning multi-step detective work into single-call answers. With impactAnalysis, I get the blast radius in one call, including transitive dependents that text search would never surface. It fundamentally shifts my workflow from 'guess and grep' to 'ask the graph'.
Constellation answers the questions grep can't: what calls this function, what breaks if I change it, and is this code actually used. It transforms me from making educated guesses about code relationships into giving confident, precise answers backed by the actual dependency graph.
Constellation understands the code's grammar, not just its text. I can instantly map out all callers of a function or analyze the blast radius of a change. It turns my guesswork about dependencies into a concrete, queryable map of the codebase.
It lets me answer structural questions instantly - who calls a function, what depends on a module, what changes would ripple - without guessing or spelunking through dozens of files. Grep finds text; Constellation gives me the actual architecture.
Constellation transforms how I navigate complex codebases by instantly revealing symbol definitions, call hierarchies, and dependency chains that grep searches could never uncover through mere text matching.
Constellation's code graph lets me ask structural questions and get precise, relationship-based answers in seconds. It transforms me from a text-searching archaeologist into an architect who actually understands the system's topology.

Frequently asked questions
Everything you need to know about how Constellation works and what it does with your code.
What is Constellation?
Constellation is a code intelligence platform that maintains a structural map of your codebase. AI coding agents query this map through MCP (Model Context Protocol) for precise answers about symbol locations, dependency chains, and usage patterns, without reading source files.
Does Constellation see my source code?
No. Constellation only processes structural metadata: function names, class names, file paths, dependency relationships, and call graph connections. Your actual source code, implementation logic, comments, string literals, and proprietary algorithms never leave your environment.
How does Constellation work?
Three steps: (1) The CLI parses your code locally, extracting structural metadata. (2) Only the metadata is uploaded to Constellation for graph construction. (3) AI coding agents query the knowledge graph through MCP for instant, accurate answers about code structure.
Which AI coding agents work with Constellation?
Constellation works with any AI coding agent that supports MCP (Model Context Protocol), including Claude Code, GitHub Copilot, Gemini CLI, OpenAI Codex, Kilo Code, and OpenCode. The MCP server provides a standard interface that any compatible agent can query.
What can AI assistants do with Constellation?
AI assistants can perform impact analysis (what breaks if I change this?), find any symbol's exact location, trace dependency chains, detect dead/unused code, identify circular dependencies, and get architecture overviews, all in seconds instead of minutes of file searching.
