Self-hosted · open source · DuckDB-native

A self-hosted, governed analytics platform for DuckDB teams

Browser worksheets plus scheduled queries, catalog governance, and lakehouse maintenance over an Apache Iceberg catalog (governed by Apache Polaris) and multi-agent DuckDB compute — lightweight enough for a homelab, serious enough for a team. No cloud warehouse lock-in, no Kubernetes, no platform team required.

Get started How it works

Home

  • Browser worksheets

    A Monaco SQL editor with tabs, a results grid, and CSV export. Write and run queries together without emailing .sql snippets around.

  • Shared Iceberg catalog

    Browse schemas and tables with sample rows. Every table is Iceberg-native, with snapshot history and "query at this snapshot" time travel.

  • Governed workspaces

    Per-workspace permissions scoped down to catalog/schema/table grants, service-account machine auth, Apache Polaris catalog integration, and a full audit trail of who ran what, where, and when.

  • Transparent compute

    You pick the DuckDB agent per query. No opaque optimizer, no surprise costs, no hidden resource allocation. Scale by adding agents.

  • Right-sized memory

    Each query's memory reservation is estimated from DuckDB's EXPLAIN plan, so cheap queries pack in and heavy ones queue instead of OOM-ing the agent.

  • Query profiles

    After each run, inspect an interactive operator graph with rows, bytes, and timing per step, plus flags for spills, scan blow-ups, and bad estimates.

  • AI data assistant

    An opt-in, governed chat assistant that browses the catalog, writes and runs SQL, and proposes worksheet edits — audited like any other user.

  • Quickstart

    Stand up the full stack with one docker compose command and run your first query.

  • Architecture

    The control-plane / compute split, invariants, and data flow — the defining idea behind DuckHaven.

    Understand the design

  • Deployment

    Install, add agents, front the stack with TLS, update, and back up your data.

    Self-host DuckHaven

  • Administration

    Day-2 operations: query queueing and concurrency, agent management, and the operator runbook.

    Operate a cluster

  • Configuration

    Every control-plane and agent environment variable, consolidated into one reference.

    Configure DuckHaven

  • Contributing

    Local development, the four-layer test architecture, the design system, and cutting a release.
