Spectrale is a tool for discovering and visualizing technical system architectures. It combines software architecture mapping with an AI infrastructure assistant called Guardian. The platform discovers, visualizes, and helps users understand their technical architecture across code, services, data, and infrastructure. It follows authorized sources and available evidence to reconstruct the system map. The tool begins by connecting to a repository, domain, cloud account, or API. It reconstructs the architecture from the evidence it can reach and identifies remaining boundaries instead of assuming the map is complete. Users can explore components and relationships in context, inspect what was found and what still needs access, and re-run discovery as the environment changes. The architecture is presented as a panorama that links source and build processes, applications, data and state, infrastructure, and external services. Spectrale integrates with compatible AI tools through a secure Model Context Protocol (MCP) interface. This allows AI agents to understand components, dependencies, and discovery results within authorized boundaries. The platform also provides an AI-native IDE that turns the architecture into a visual workspace where users can edit components, redefine connections, and hand off changes to connected AI agents. Typical use cases include understanding the broader context of software systems, performing security analysis, and preparing infrastructure for AI agent interactions.
