n8n Architecture: How It Actually Works
How the n8n codebase is structured: module map, load-bearing symbols, and dependency structure, generated by Symvanta.
Symvanta Architecture
These are auto-generated software architecture maps: real module structure, dependency cycles, and load-bearing symbols computed straight from the Symvanta code graph of well-known open source repositories. Each page is pinned to a single commit, so every number and diagram is reproducible against that exact snapshot. The same analysis runs on any private codebase you point Symvanta at: see it on your own code with a free 7-day trial.
Read one to see how a large system actually fits together: which modules everything depends on, where the dependency cycles hide, and which few symbols carry most of the call graph. This is the view an AI agent gets over MCP before it touches your code, so blast radius and cross-repo impact are known up front instead of discovered in review.
