What is GrowthBook?
GrowthBook is an open-source feature flagging and A/B testing platform that lets teams run experiments and manage feature rollouts using their existing data warehouse, rather than relying on a separate analytics silo. This warehouse-native, open-source approach is its defining feature: GrowthBook connects to the data you already have (in warehouses like Snowflake, BigQuery and others), so your experiment results are based on your real, trusted metrics, and you maintain control and ownership over your data and infrastructure.
The platform provides feature flags to roll out and control features safely — gradual releases, targeting and instant rollbacks — alongside a powerful experimentation engine for running A/B tests and analyzing their statistical results. Because it queries your data warehouse for results, you can measure the impact of experiments on the metrics that matter to your business using data you trust, without duplicating tracking or depending on a vendor's numbers. Being open source, GrowthBook can be self-hosted for full control, privacy and cost efficiency, with a managed cloud option available, and it benefits from transparency and community contributions.
GrowthBook is popular with product, engineering and data teams that want a rigorous, data-driven approach to experimentation and feature management while keeping their data in their own warehouse and avoiding lock-in. Its combination of feature flags, warehouse-native experimentation and open source appeals especially to data-mature teams and those who value ownership and flexibility. As experimentation becomes a core practice for building better products and companies increasingly centralize their data in warehouses, warehouse-native, open-source experimentation tools are a natural fit. For teams that want to manage feature flags and run trustworthy A/B tests using their existing data warehouse — with the freedom of open source — GrowthBook offers a capable, transparent and well-designed solution.
What is Lightdash?
Lightdash is an open-source business intelligence (BI) platform built to work natively with dbt, the popular data transformation tool that has become a standard in the modern data stack. Lightdash's core idea is to let data teams define their metrics and models once, in dbt, and then expose them through a self-serve BI layer so the whole organization can explore data and build dashboards — without duplicating metric definitions or maintaining a separate, disconnected BI semantic layer. This keeps a single source of truth from data modeling all the way to the charts business users see.
For data teams already using dbt, this integration is genuinely elegant. The metrics and dimensions you define in your dbt project become directly available in Lightdash, so analysts and business users can slice and visualize data confidently, knowing the numbers are governed and consistent. This solves a perennial problem where BI tools redefine metrics separately, leading to conflicting numbers and endless "why don't these match?" debates. Lightdash keeps the definitions in code, version-controlled and trustworthy.
As an open-source tool, Lightdash can be self-hosted for control and cost efficiency, inspected and extended, and adopted without the lock-in and expense of proprietary enterprise BI platforms; a cloud option exists for convenience. It provides the expected BI capabilities — interactive exploration, dashboards, charts, scheduling and sharing — while staying close to the developer-friendly, code-first ethos of the modern data stack. This makes it especially appealing to data-savvy teams who use dbt and want their BI to align with that workflow. For organizations that want governed, self-serve analytics built on a single source of truth, and that value open source and the dbt ecosystem, Lightdash offers a thoughtful, modern and well-integrated BI solution.
