Lightdash

Lightdash

Open-core, dbt-native BI that turns metrics and dashboards into version-controlled code. The MIT core is self-hostable; SSO and fine-grained RBAC sit behind the paid tier.

🩺 Vitals

What do these metrics mean?
  • Last active: when code was last pushed, as of our last check. The dot is green when that was recent, grey otherwise. A long gap can mean a tool is finished and stable, not only unmaintained.
  • Latest release: the most recent tagged, packaged version the maintainers published. Not every healthy project tags releases.
  • Open issues: unresolved reports and requests. A high number is normal for a popular project and is not a warning on its own.
  • Stars: how many people bookmarked the project on its forge. A rough popularity signal, not a measure of quality.

🏗️ Profile

1. The Executive Summary

What is it? Lightdash is a business intelligence tool that lives inside the dbt workflow. (dbt is the standard tool data teams use to define and transform data in the warehouse.) Instead of rebuilding metric definitions inside a separate BI interface, Lightdash reads the metrics already defined in your dbt project and turns them into charts and dashboards. Every dashboard exports to version-controlled YAML, so your BI layer lives in git alongside your code rather than locked in a vendor's UI.

This is the sharpest expression of BI-as-code in the open source landscape. Where Metabase and Redash connect to a database and let analysts build queries in their own interface, Lightdash treats your dbt project as the single source of truth, so metric definitions move into code review instead of living as clicks. The trade-off is scope: the free MIT core is a genuine BI platform, but the governance features enterprises expect (SSO beyond Google OAuth, fine-grained RBAC, SCIM) sit behind the paid Enterprise tier.

The Strategic Verdict:

2. The "Hidden" Costs (TCO Analysis)

Cost Component Looker (SaaS) Lightdash (Self-Hosted)
Semantic Layer LookML (proprietary, Looker-locked) dbt (open, git-tracked)
Analyst & Viewer Seats Per-user platform licensing $0 (Unlimited, Core)
SSO & Custom RBAC Bundled in platform Enterprise tier (paid)
