butterbase vs structurizr

butterbase: Butterbase is an open-source, AI-native backend-as-a-service built on Postgres. Each app gets its own database with row-level security, plus auth, file storage, serverless functions, realtime subscriptions, an AI gateway, RAG and an MCP server, so coding agents can operate the backend through tools. It can be self-hosted with Docker Compose or used as a managed cloud.; structurizr: Structurizr is a "models as code" tool that helps create multiple software architecture diagrams from a single model using its DSL, based on the C4 model. It offers both a web-based playground and a local Docker-based solution for diagram generation.
