Overview

AI-generated overview

DataRaum is a local metadata context engine that learns the concepts, relationships, rules and measures behind an organization's data and grounds them in the 数据

What you can do
Learns what data columns mean — concepts, relationships, rules and measures — and grounds each in the actual data with a measured confidence score, going beyond a column-name semantic layer. Runs durable analysis over data sources and writes metadata into a per-workspace Postgres schema. Hosts a chat agent in a web cockpit that renders results and triggers engine workflows. Organizes work into isolated workspaces, each with its own engine and cockpit containers behind a portal and reverse proxy. Supports running from source or from published release images.
When to use it
Use it when you want an assistant to help build and explore a semantic understanding of an organization's own data — its concepts, relationships and measures — rather than just column names. Suited to teams willing to run a multi-container platform locally or on a deploy host.
Requirements
Runs as a local multi-container platform (Docker Compose) with Postgres, an S3 object store and Temporal, plus a portal and Caddy ingress. Requires an Anthropic API key in ANTHROPIC_API_KEY for LLM-powered semantic analysis. DATARAUM_HOME sets the root directory for workspaces, sessions and exports. Caddy binds port 80 by default; a build toolchain is needed unless using published release images.
Before you install
Requires an Anthropic API key, which is placed in an environment file and used for LLM-powered analysis, so data may be sent to that provider. The stack writes metadata to Postgres and an object store and provisions workspaces. The README shows default development credentials for the portal; do not expose them. Caddy needs port 80, which may conflict with other services.

Installation

In SourceWeft

  1. Open DataRaum in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

README

DataRaum

[License]

The understanding layer that grounds an organization's operating model in its own data.

A semantic layer tells BI tools what columns are called. DataRaum learns what they mean — the concepts, relationships, rules, and measures of the organization — and grounds each one in the actual data, with a measured confidence behind it. See the docs for the full picture.

Status

DataRaum runs as a multi-container platform, isolated per workspace:

  • engine (Python) — a Temporal activity worker, no HTTP. Does the durable analysis (add_source, begin_session, operating_model) and writes metadata to the workspace's Postgres schema.
  • cockpit (TanStack Start) — the web app you use. Hosts the chat agent, renders the results, and orchestrates the journey by triggering engine workflows via Temporal.

Each workspace runs its own pair of those two containers. In front of them sit the portal (the cockpit image in a second role — login, membership routing, workspace provisioning) and Caddy, which serves the portal on the parent domain and each workspace on its own subdomain.

They share one substrate: Postgres (metadata + cockpit state + catalogs), an S3 object store (the DuckLake data lake + uploads), and Temporal (durable orchestration). No HTTP seam between engine and cockpit — the integration surface is Postgres + Temporal. See the platform architecture.

Quick start

bash
# Set the LLM keycp packages/infra/.env.example packages/infra/.envecho "ANTHROPIC_API_KEY=sk-ant-..." >> packages/infra/.env
# Bring up the whole installation (substrate, engine worker + cockpit for the# default workspace, portal, and the Caddy ingress)docker compose -f packages/infra/docker-compose.yml up -d --wait
# Engine health = the Temporal worker heartbeat (no HTTP endpoint):docker compose -f packages/infra/docker-compose.yml run --rm --no-deps \  --entrypoint temporal temporal-admin-tools \  worker list --namespace default --address temporal:7233   # → Status: Running
# Sign in at the portal, then open the default workspace from thereopen http://dataraum.localhost              # [email protected] / dataraum-dev

Caddy routes by hostname: the parent domain serves the portal (login + your workspaces), and each workspace has its own subdomain (http://ws1.dataraum.localhost). localhost:3000 is published for debugging only — the session cookie is scoped to the parent domain, so a browser there is redirected to the portal and a script gets 401.

The thing that bites on a first run: Caddy binds port 80. If something already holds it (macOS ships Apache), up fails at container start and the portal never comes up — set CADDY_HTTP_PORT and a matching DATARAUM_PORTAL_ORIGIN to move it. (*.localhost needs no /etc/hosts entry.)

Compose defines exactly one workspace pair — bootstrap scaffolding, so a fresh install has something to log into and something for the provisioner to clone. Every other workspace is created from the portal (New workspace) or bun run workspace:create; compose does not grow a service per workspace.

Full walkthrough, including troubleshooting: Running the stack.

For UI iteration, run the cockpit dev server outside docker for hot reload — see packages/cockpit/README.md.

Run a released version (published images)

The quick start above builds the engine and cockpit from source. To run the published release images instead — a deploy host, no build toolchain — layer the release overlay and name the version:

bash
export DATARAUM_VERSION=1.2.3          # any tag from a GitHub Releasedocker compose \  -f packages/infra/docker-compose.yml -f packages/infra/docker-compose.release.yml \  --env-file packages/infra/.env up -d --wait --no-build

This pulls ghcr.io/dataraum/{dataraum, dataraum-cockpit, dataraum-cockpit-migrate} at that tag. See Deployment for the images, schema/migration handling, and the per-workspace topology.

Develop

  • Engine (Python): cd packages/engine && uv sync --group dev && uv run pytest --testmon tests/unit -q. See packages/engine/README.md and packages/engine/CLAUDE.md.
  • Cockpit (TypeScript): cd packages/cockpit && bun install && bun --bun run dev (the --bun flag is required). See packages/cockpit/README.md and packages/cockpit/CLAUDE.md.
  • Pull the engine metadata schema (cockpit): cd packages/cockpit && DATARAUM_WORKSPACE_ID=<id> METADATA_DATABASE_URL=<url> bun run db:pull:metadata. Re-run after the engine adds/changes SQLAlchemy models.

Documentation

Platform docs live in docs/ (workspace root) and are published via Zensical. Start at docs/index.md, or serve the site locally:

bash
uv run --project packages/engine zensical serve   # run from the repo root
