Macro is a large open-source monorepo (AGPLv3) for an all-in-one collaborative productivity platform that unifies email, messaging, documents, tasks, CRM, AI agents, and more. The backend consists of 42+ Rust microservices following a consistent hexagonal architecture (domain/inbound/outbound), with PostgreSQL, OpenSearch, Redis, S3, Kafka/SQS/EventBridge for data storage and event-driven processing. The frontend is a SolidJS single-page application with a heavily customized Lexical editor, block-based content system, real-time collaboration via CRDT (Loro), and Tauri-based desktop/iOS apps. AI is a first-class feature with agent harnesses, MCP integration, and an AI editing worker. Infrastructure is managed via Pulumi and Docker Compose for local development. The codebase demonstrates high engineering craftsmanship with consistent patterns, extensive testing, and comprehensive observability, though the sheer scale and volume of generated code introduce some maintenance overhead.
TidGi-Desktop is a cross-platform Electron application that integrates TiddlyWiki (a personal wiki) with AI agent capabilities, Git synchronization, and modern desktop features. It allows users to manage multiple workspaces (folder-based or single-file HTML wikis), sync with Git remotes, and interact with AI agents for chat, tool execution, and knowledge management. The architecture is Electron multi-process with main process, renderer processes (multiple windows), and a utility process for wiki worker. Services are wired via Inversify DI container and communicate via typed IPC (electron-ipc-cat). Key entry points include src/main.ts (Electron main), src/renderer.tsx (React renderer), src/services/agentInstance/ (AI agent lifecycle), src/services/wiki/ (wiki management), and src/services/git/ (Git operations). External dependencies include TiddlyWiki, Git (via dugite), SQLite (TypeORM), various AI SDKs (OpenAI, Anthropic, etc.), OAuth providers, and system-level integrations. The codebase is well-structured with a service-oriented architecture, extensive test coverage (unit, E2E, BDD), and a rich preference system driven by Zod schemas. It demonstrates high craftsmanship in areas like AI prompt concatenation, tool registration, and file system watching, though some modules are tightly coupled to the application's domain.
