+ +--- + +## ๐Ÿš€ Why CodeGraph? + +Without CodeGraph, Claude Code spawns expensive exploration agents that make dozens of API calls to understand your codebase. **CodeGraph changes that.** + + + + + + +
+ +### โŒ Without CodeGraph +``` +Exploring codebase... +โ†ณ 21 tool calls +โ†ณ 37,700 tokens consumed +โ†ณ 70 seconds +โ†ณ ~$0.50-2.00 per exploration +``` + + + +### โœ… With CodeGraph +``` +Building context... +โ†ณ 1-3 tool calls +โ†ณ Local MCP (0 tokens) +โ†ณ 35 seconds +โ†ณ $0.00 for exploration +``` + +

+ +### ๐Ÿง  Smart Context Building +One tool call returns everything Claude needsโ€”entry points, related symbols, and code snippets. No more expensive exploration agents. + + + +### ๐Ÿ” Semantic Search +Find code by meaning, not just text. Search for "authentication" and find `login`, `validateToken`, `AuthService`โ€”even with different naming conventions. + + + +### ๐Ÿ“ˆ Impact Analysis +Know exactly what breaks before you change it. Trace callers, callees, and the full impact radius of any symbol. + +
+ +### ๐ŸŒ 15+ Languages +TypeScript, JavaScript, Python, Go, Rust, Java, C#, PHP, Ruby, C, C++, Swift, Kotlinโ€”all with the same API. + + + +### ๐Ÿ”’ 100% Local +No data leaves your machine.
