OpenTrace

A knowledge graph that maps your codebase structure, service architecture, and system relationships — then exposes it all through MCP so AI tools can understand your systems.

Try it now at oss.opentrace.ai — no install required, runs entirely in your browser.

What It Does

OpenTrace indexes source code directly in your browser — no server required. Point it at a GitHub or GitLab repo and it will:

1. Parse every file using tree-sitter WASM grammars (12 languages)
2. Extract classes, functions, imports, and call relationships
3. Build a knowledge graph stored in LadybugDB WASM (embedded graph database)
4. Summarize every node using template-based identifier analysis
5. Expose the graph to an in-app chat agent via MCP tools

Quick Start

git clone https://github.com/opentrace/opentrace.git
cd opentrace
make install
make ui

Open http://localhost:5173, add a GitHub repo, and explore the graph.
