Architecture
A real computer behind the conversation.
Matrix brings agents, tools, and persistent work into one private cloud workspace. Here is how the pieces fit together.
01
Your computer
A per-user cloud machine keeps the runtime, files, projects, and installed tools together. Production updates replace application code while preserving your home directory. Builder and Max support always-on work; Starter sleeps when inactive.
02
The AI kernel
The kernel coordinates agent sessions and tools. Matrix uses the Claude Agent SDK, with support for running other coding agent harnesses in the workspace. Available models, credentials, and usage limits depend on your setup.
03
Your interfaces
The web app and desktop app connect to the same core. Messaging adapters provide another way to reach supported agent workflows. The core can run independently of a visual interface.
04
Your data
Files hold projects, identity, configuration, and exportable state. Application and durable runtime data use PostgreSQL. Owner boundaries apply to personal, organization, and shared data.
05
Permissions and review
Authentication, input validation, tool permissions, resource limits, and timeouts form multiple layers of protection. Connected tools require appropriate access. Review outputs and explicitly authorize sensitive actions in your workflow.
