Aria Host is an AI's 'workstation': instead of having everything scattered, it brings into one environment what an AI needs to operate — its memory, its credentials, a browser, the language models and its tools. It can host Aria and other entities at once, each with its own space.
It runs first on its own machine (local-first) and is designed to move to the cloud without a rewrite. Each piece is an independent service, so it can be started, tested and scaled on its own.
Memory uses retrieval by meaning (RAG) and stays separated per entity. Credentials live in an encrypted secrets manager — never in plain text or in the logs — classified by project, service and client.
Everything is offered through a single tools surface (an MCP gateway + REST API): memory, secrets, browser, models and command execution. Commands run in an isolated container, not on your machine, and the model providers are swappable — no lock-in to a single one.
- Multi-entity RAG memory with retrieval by meaning
- Encrypted secrets manager (vault) by project and service
- Automated browser, multi-model engine and isolated execution
A single tools surface (MCP gateway + REST) through which the AI uses memory, secrets, browser, models and commands.
A REST API over each service — memory, vault, browser and model engine — with cost control, plus an MCP gateway for agents.
