If you want a free, open-source alternative to Google Data Studio, start by matching the tool to your workload: Metabase is the broadest fit for business reporting and visual or SQL-based exploration; Grafana OSS is built around operational data such as metrics, logs, and traces; and Lightdash suits analytics teams that work with code and governed metrics. They are not interchangeable, and “free” does not mean there are no hosting, maintenance, or licensing considerations.
What “free” and “open source” mean when choosing a replacement
Free access and open-source licensing are different things. A hosted product can be free to use without making its code open source, while open-source software may still require paid infrastructure and staff time to deploy and maintain. A recent comparison makes this distinction for Looker Studio and the alternatives it discusses, but it is secondary coverage rather than an official Google source: Capterra’s comparison of open-source BI tools.

The title uses the older name “Google Data Studio.” The available comparison refers to the product as Looker Studio, but the sources gathered here do not establish Google’s naming history, current feature set, or pricing. This article therefore focuses on the alternatives and does not make claims about Google’s current plans.
Which alternative fits your analytics work?
| Tool | Best fit | Typical workflow | Key consideration |
|---|---|---|---|
| Metabase | General-purpose business intelligence and reporting | Visual question building or SQL, followed by dashboards | Its Open Source Edition is AGPL-licensed; review edition and embedding terms. |
| Grafana OSS | Infrastructure, application monitoring, and operational dashboards | Query and visualize metrics, logs, and traces; configure alerts | Self-managed, so infrastructure, engineering time, and maintenance are part of the cost. |
| Lightdash | Code-centered analytics teams that want governed metrics | Work through a context layer using a dbt project or standalone Lightdash YAML | The repository’s MIT grant has an explicit exception for the backend enterprise directory. |
Metabase: a flexible starting point for business reporting
Metabase describes itself as an open-source BI platform for exploring data and building dashboards. Its documentation covers both a graphical question builder and SQL editor, along with interactive dashboards. It can be run as a JAR or in Docker, or used through Metabase Cloud; those routes involve different deployment and operating responsibilities. See the Metabase documentation.
#1 Best Overall
That combination makes it a practical candidate when some colleagues want to explore data visually while others prefer writing SQL. The Open Source Edition is licensed under AGPL. Metabase distinguishes it from commercial licensing and source-available Enterprise features, and its licensing page describes conditions for embedding. Teams planning customer-facing embedded analytics should read the current terms rather than assume that self-hosting or an open-source edition automatically permits every use: Metabase licensing information.
Choosing a no-license-charge edition does not determine your total cost: a self-hosted deployment still needs infrastructure and someone to operate it. Metabase Cloud is a separate hosted route, not evidence that all deployment options are free.

Grafana OSS: choose it for operational data, not as a generic BI clone
Grafana OSS is designed to query, visualize, alert on, and explore metrics, logs, and traces. Its documentation emphasizes infrastructure and application monitoring, observability, and operational dashboards, and describes a plugin framework for other data sources. That makes it a strong fit when the audience needs to watch systems and investigate changing operational signals—not necessarily when business users mainly need conventional reporting. Consult Grafana’s OSS documentation and its Grafana OSS overview.
The OSS edition is self-managed and does not include managed infrastructure or enterprise governance features described for other offerings. Grafana Labs puts the trade-off plainly: “Free to license doesn’t mean free to run.” Infrastructure, engineering time, and maintenance remain real costs even when there is no software license charge.
Lightdash: for analytics-as-code and governed metrics
Lightdash is aimed at data teams that want metrics and dashboards organized through a context layer and code-oriented workflows. Its repository describes using a dbt project or standalone Lightdash YAML, as well as self-hosting and commercial enterprise features. This approach is most natural when the team is comfortable managing definitions in code and wants analytics to reflect a governed model rather than relying only on ad hoc dashboard building. See the Lightdash documentation and Lightdash repository.
Read the repository license carefully: the general MIT grant excludes the backend enterprise directory, which has its own license. It would be inaccurate to describe every component as MIT-licensed.

How to make the choice
- Start with the data and audience. For broad business reporting, explore Metabase. For metrics, logs, traces, and operations teams, consider Grafana OSS. For modeled metrics and a code-centered data team, consider Lightdash.
- Match the query workflow. Decide whether users need visual exploration, direct SQL, or analytics built around code and modeled definitions. Metabase documents visual and SQL workflows; Lightdash documents its context-layer approach; Grafana’s focus is operational exploration and monitoring.
- Decide who will run it. If you choose a self-managed edition, account for infrastructure, upgrades, maintenance, and the people responsible for them. Metabase also documents a hosted option; hosted availability and terms are separate from the open-source software.
- Check license and embedding needs. Confirm the current license for the exact edition and components you plan to use. For AGPL software or customer-facing embedding, review the vendor’s applicable terms and obtain legal advice if the intended use is unclear.
- Separate core software from managed support. Verify which features belong to the open-source edition and which require managed hosting, commercial features, or official support before committing to a deployment.
What about Apache Superset?
Apache Superset appears in a recent secondary comparison as a free, open-source BI option for SQL-driven analytics. The source available here does not establish its current license, setup requirements, or detailed feature set from primary documentation. Treat it as a candidate for further evaluation, not as a fully assessed recommendation; verify those details against Apache Superset’s official materials before selecting it.
