indxr vs barbacane

indxr: indxr gives AI coding agents a structural map of codebases, reducing token costs by ~5x compared to reading full files. It supports 27 languages, provides a 22-tool MCP server for live queries, and features incremental caching, git structural diffing, and dependency graphs. Setup is one-command with `indxr init` for popular AI coding agents.; barbacane: Barbacane is a spec-driven API gateway built in Rust. It uses OpenAPI/AsyncAPI specs as configuration, compiles them into sealed artifacts, and provides routing, validation, authentication, AI traffic management, and MCP support. It features fast performance, security by default, and an extensible plugin system.
