Aster

About Aster

Aster is a self-hosted AI workspace you run yourself. One durable place where a single owner can:

• hold persistent AI conversations with streamed responses
• plug in any OpenAI-compatible model endpoint, with explicit role routing
• maintain approved, queryable memory across sessions
• attach private documents with lexical + embedding search
• run bounded agents that can call tools but stay inside limits you set
• automate against IMAP / Discord / other channels

Highlights

• Provider-neutral — model catalogs, per-model profiles, ordered fallbacks
• Approved memory — the agent can't remember anything you didn't allow
• Controlled tools — MCP over Streamable HTTP or stdio, per-tool enablement, confirmation flow, full audit history
• Private media — image generation and editing kept in your local storage
• Durable workspace — automations, IMAP/Discord communications, manual and AI-assisted scheduling

Deployment

docker compose up — one Postgres, one volume for media, one Aster service. No external SaaS required.
