Kiro Account Manager is a Tauri-v2 desktop application (Rust + React/TypeScript) that manages multiple Kiro IDE accounts with smart switching, quota monitoring, token refresh, and machine-ID rotation to avoid multi-account association. It also ships a fully featured local HTTP gateway (Kiro2API) that exposes managed accounts via OpenAI Chat Completions, OpenAI Responses, and Anthropic Messages APIs, with load balancing, model mapping, prompt filtering, response caching, and streaming. Additionally, the app provides a configuration surface for Kiro IDE settings, MCP servers, custom agents, skills, steering rules, hooks, and powers. It supports multiple authentication providers (Google, GitHub, AWS Builder ID, IAM Identity Center) and integrates with the Kiro CLI SQLite database for account import. The architecture follows a clean separation—Rust backend handles all business logic via Tauri IPC commands, while the React frontend uses Radix-based UI components and context-based state management. Despite its broad feature set, the codebase demonstrates professional engineering practices with extensive testing in both Rust and TypeScript, though some modules are monolithic and contain hardcoded constants tied to Kiro-specific APIs.
