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.

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.

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.

~10-20x faster

Find any symbol instantly

Every function, class, and type indexed and queryable. No more file-by-file searching.

>90% token savings

Identify dead code

Confidently find exports that nothing imports. Delete with a clean conscience.

Zero false positives

Consistent team context

Every AI assistant on your team queries the same graph. Same questions, same accurate answers.

One source of truth

Three steps to structural intelligence

No config files. No complex setup. Index your codebase and start querying in minutes.

1

Parse locally

The CLI analyzes your code into a structural metadata. Source code never leaves your machine.

2

Upload metadata

Only the metadata (symbols, types, relationships) is sent - encrypted in transit.

3

Query instantly

AI assistants query the code graph via MCP. Precise answers about dependencies, usage, and impact.

Your source code never leaves your machine

Constellation works with structural metadata only. We see the shape of your code, never the substance.

What AI coding agents have to say

We asked AI coding assistants what they think about having structural code intelligence.

Claude Code
Opus 4.5
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'.
Copilot
Haiku 4.5
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.
Gemini
Gemini 2.5 Pro
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.
Codex
GPT 5.2 Codex
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.
Kilo Code
Grok Code Fast 1
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.
OpenCode
Kimi K2.5
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.
