docglow 0.4.1

Next-generation dbt documentation site generator

docglow

Next-generation documentation site generator for dbt™ Core projects.

Why Docglow?

Over 60,000 teams use dbt Core without access to dbt Cloud's documentation features. The built-in dbt docs serve generates a dated, hard-to-navigate static site that doesn't scale.

Docglow replaces it with a modern, interactive single-page application — and it works with any dbt Core project out of the box.

• No dbt Cloud required — generate and serve docs locally or deploy anywhere
• Unlimited models, unlimited viewers — no seat caps, no model limits
• Zero configuration — just point it at a dbt project with compiled artifacts and go
• Interactive lineage explorer — drag, filter, and trace upstream/downstream dependencies visually
• Project health scoring — get a coverage report for descriptions, tests, and documentation completeness

Interactive lineage explorer — layer-grouped DAG with upstream/downstream filtering, depth control, and folder grouping

Column-level lineage — expand nodes to trace individual columns across models with transformation labels (direct, derived, aggregated)

Column table with lineage — view types, descriptions, tests, and upstream/downstream dependencies for every column. Click a lineage badge to jump directly to that column in the linked model.

Install

pip install docglow

Try It in 60 Seconds

pip install docglow
git clone https://github.com/docglow/docglow.git
cd docglow
docglow generate --project-dir examples/jaffle-shop --output-dir ./demo-site
docglow serve --dir ./demo-site

This uses the bundled jaffle_shop example project with pre-built dbt artifacts.

Quick Start

# Generate the site from your dbt project
docglow generate --project-dir /path/to/dbt/project --output-dir ./site

# Serve locally
docglow serve --dir ./site

Features

• Interactive lineage explorer — drag, filter, and explore upstream/downstream dependencies with configurable depth and layer visualization
• Column-level documentation — searchable column tables with descriptions, types, and test status
• Project health score — coverage metrics for descriptions, tests, and documentation completeness
• Full-text search — instant search across all models, sources, and columns
• Single static site — no backend required, deploy anywhere (S3, GitHub Pages, Netlify, etc.)
• Dark mode — auto, light, and dark themes (follows system preference by default)

CLI Commands

Command	Description
docglow generate	Generate the documentation site from dbt artifacts
docglow serve	Serve the generated site locally
docglow health	Show project health score and coverage metrics
docglow init	Generate a starter docglow.yml configuration file
docglow profile	Run column-level profiling (requires docglow[profiling])

Single-File Mode

Generate a completely self-contained HTML file — no server needed:

docglow generate --project-dir /path/to/dbt --static
# Open target/docglow/index.html directly in your browser

The entire site (data, styles, JavaScript) is embedded in one file. Perfect for sharing via email, Slack, or committing to a repository.

Configuration

Add a docglow.yml to your dbt project root for optional customization (layer definitions, display settings, etc.). Docglow works out of the box without any configuration — just point it at a dbt project with compiled artifacts in target/.

Generate a starter config with all options documented:

docglow init

Theme

Docglow supports three themes: auto (follows system preference), light, and dark.

docglow generate --theme dark

Or in docglow.yml:

theme: dark  # auto | light | dark

CI/CD

Use Docglow as a CI quality gate with the --fail-under flag:

# .github/workflows/docs.yml
- name: Check documentation health
  run: docglow health --project-dir . --fail-under 75

- name: Generate and deploy docs
  run: docglow generate --project-dir . --output-dir ./site

Ready-to-copy workflow files for GitHub Pages, S3, and health checks are available in docs/ci-examples/.

Pre-commit

Add Docglow's health check to your existing pre-commit workflow:

# .pre-commit-config.yaml
repos:
  - repo: https://github.com/docglow/docglow
    rev: v0.4.0
    hooks:
      - id: docglow-health
        args: ['--fail-under', '75']

Requirements

• Python 3.10+
• A dbt project with target/manifest.json (run dbt compile or dbt run first)
• See Compatibility for supported dbt versions and adapters
