Partial The UI, MCP server, and local-first packaging are buildable, but accurately mapping API, service, and database connections across many languages and repos is a hard static-analysis problem.
What it would actually take: Build a local CLI/daemon with per-language parsers (AST-based, using tree-sitter or language servers) that extract endpoints, clients, schemas, and DB references, then store the graph in SQLite or a graph DB. Add a diff engine that flags breaking changes against that graph, plus an MCP server to expose it. The hard part is parser coverage and resolving cross-repo references with few false positives, which takes compiler-level expertise and extensive testing against real codebases.
