Know What Breaks
Before You Change It
Ask "what depends on this function?" and get an instant answer. ContextStream maps your entire codebase so you can refactor with confidence.
The Refactoring Problem
Every developer has broken something they didn't know depended on what they changed.
Hidden Dependencies
You change a utility function. Three services break in production. Nobody knew they all used it.
Circular Dependencies
Module A imports B, B imports C, C imports A. Build times explode. Nobody knows where to start fixing it.
Dead Code
Your codebase has thousands of lines nobody uses. You're afraid to delete anything because "what if something needs it?"
A Complete Map of Your Codebase
ContextStream builds a knowledge graph of how your code connects. Query it anytime.
Dependency Analysis
Query what depends on any file, function, or module. See the full dependency tree.
graph(action="dependencies",
target="src/utils/auth.ts")
→ 12 files, 47 functions
Impact Analysis
Before changing anything, see exactly what would be affected.
graph(action="impact",
target="validateUser")
→ 3 API routes, 2 middleware
Analysis Capabilities
Dependency Queries
See what depends on any file, function, or module in your codebase.
Call Path Tracing
Trace execution flows between any two points in your code.
Impact Analysis
Understand exactly what would be affected by proposed changes.
Circular Detection
Automatically detect and visualize circular dependency chains.
Dead Code Finder
Identify unreferenced exports and unused code for cleanup.
Graph Visualization
See your codebase as an interactive knowledge graph.
Two Levels of Analysis
Choose the depth of analysis that fits your needs.
Graph-Lite
Module-level import graph with 1-hop impact analysis. Perfect for understanding direct dependencies.
- Module-level dependency mapping
- Direct impact analysis (1-hop)
- Circular dependency detection
Full Graph
Complete call/dataflow/type analysis with deep impact tracing. Full codebase understanding.
- Function-level dependency mapping
- Deep impact analysis (multi-hop)
- Call path tracing
- Dead code detection
