For general-purpose business intelligence, start with Metabase; for infrastructure and observability dashboards, consider Grafana OSS; and for analytics teams that work from dbt models or code, look at Lightdash. They solve different problems, so the best choice depends on your data workflow, who will operate the software, and whether you need customer-facing embedding.
“Free” and “open source” are not interchangeable: a free hosted service may be proprietary, while self-hosted open-source software can still require infrastructure and staff time. Google Data Studio is now commonly referred to as Looker Studio in current comparisons, but the alternatives below are assessed on their own workflows and terms, not on unverified claims about Google’s current features or pricing.
Which alternative fits your analytics workflow?
| Tool | Best fit | Workflow | Deployment and licensing notes |
|---|---|---|---|
| Metabase | General-purpose business reporting and data exploration | Visual question building and SQL | Can be self-hosted or used through Metabase Cloud. Its Open Source Edition is AGPL-licensed; commercial features and some embedding paths have separate terms. |
| Grafana OSS | Infrastructure, application monitoring, and observability dashboards | Explore and visualize metrics, logs, and traces; configure alerts | Self-managed. You take on infrastructure, maintenance, and engineering time; enterprise governance and managed infrastructure are not part of the OSS edition. |
| Lightdash | Data teams using governed metrics and code-centered analytics | Context-layer analytics using dbt projects or standalone Lightdash YAML | Can be self-hosted. Most repository code is MIT-licensed, but the backend enterprise directory is an explicit licensing exception. |
These are not interchangeable dashboard builders. Metabase is the broadest starting point for teams that need business-facing reporting with visual and SQL options. Grafana is oriented toward operational data and monitoring. Lightdash is aimed at teams that want analytics grounded in a modeled context layer. Apache Superset also appears in a recent secondary comparison of free and open-source BI tools, but detailed setup, feature, and license claims should be checked against its current official documentation before relying on them.
Metabase: visual exploration and SQL in one BI tool
Metabase describes itself as an open-source BI platform for asking questions of data and building dashboards. Its documentation covers a graphical question-building workflow as well as a SQL editor, along with interactive dashboards. That combination makes it a reasonable first candidate when analysts and less technical colleagues need to work with the same reporting environment.
Metabase can be run as a JAR or in Docker, or used through Metabase Cloud. Self-hosting avoids a hosted-service dependency but leaves deployment and ongoing operation to your team. The Open Source Edition is AGPL-licensed, while enterprise features and some embedding options have separate terms. Review the current licensing and embedding conditions before adopting it for a product or customer-facing analytics.

Grafana OSS: dashboards for monitoring and observability
Choose Grafana OSS when the questions are about systems: how an application is behaving, whether infrastructure is healthy, or what logs and traces show. Its documentation describes querying, visualizing, alerting on, and exploring metrics, logs, and traces, with plugins available for additional data sources. It is designed for operational dashboards, not as a direct substitute for every business-user reporting workflow.
Grafana OSS is self-managed. Although there is no license charge for the OSS edition, you must account for the infrastructure, engineering time, and maintenance needed to run it. Grafana’s documentation puts the distinction plainly: “Free to license doesn’t mean free to run.” Managed infrastructure and enterprise governance features are outside the OSS edition.

Lightdash: modeled metrics and analytics-as-code
Lightdash is a stronger fit for data teams that want analytics tied to a governed context layer rather than a collection of independently defined dashboard calculations. Its workflows center on metrics and dashboards built with dbt projects or standalone Lightdash YAML, making it more natural for teams already comfortable maintaining analytics definitions as code.
Lightdash describes an open-source BI core and supports self-hosting, alongside commercial enterprise features. Its repository license is MIT for code outside specified exceptions; the backend enterprise directory has its own license. Do not assume every component is covered by the same license.

- What are you measuring? For business reporting and exploratory analysis, evaluate Metabase or Lightdash. For metrics, logs, traces, alerting, and operational monitoring, evaluate Grafana OSS.
- How will people query data? Metabase offers visual question building and SQL. Lightdash emphasizes modeled metrics and code-centered workflows. Grafana focuses on exploring and visualizing operational data.
- Who will run it? Compare hosted use with self-managed deployment. Self-hosted software requires someone to provision and maintain infrastructure; license cost alone does not capture the work.
- Will you embed analytics? Check the specific edition and current terms before building customer-facing embedding, especially where AGPL licensing or separate commercial terms may apply.
- Which governance and support features do you need? Separate open-source capabilities from managed hosting, commercial features, and official support. Verify the current boundaries in each product’s documentation rather than assuming editions are equivalent.
What “free and open source” means in practice
A no-cost hosted product and open-source software are different choices. With hosted software, the provider operates the service; with self-managed software, your organization takes responsibility for installation and operation. Open-source licensing also does not guarantee that every feature, deployment option, or embedding use is available under the same terms. Read the license and edition documentation for the exact version and use case you plan to adopt.
