A data-driven rundown of the 10 best open-source BI tools in 2025, ranked by feature depth, usability, cost, and community strength—so data teams can choose the right analytics stack with confidence.
The best Top Open Source BI Tools in 2025 are Apache Superset, Metabase, and Lightdash. Apache Superset excels at large-scale, cloud-native dashboards; Metabase offers unrivaled simplicity for non-technical teams; Lightdash is ideal for metrics-layer modeling directly on top of your dbt project.
In 2025, the open-source BI leaders are Apache Superset, Metabase, Lightdash, Redash (OSS fork), Grafana, Pentaho CE, BIRT, GoodData.CN, Cube, and SQLPad. They stand out for extensibility, no-license cost, and vibrant communities that keep pace with modern data stacks.
We scored each project across seven weighted criteria: feature depth (25%), ease of use (15%), pricing flexibility (15%), integration breadth (15%), performance (10%), community activity (10%), and support options (10%). Public GitHub metrics, release cadence, docs quality, and verified user reviews informed the scoring.
Superset tops the chart for its cloud-native architecture, SQL Lab IDE, role-based security, and 40+ built-in visualizations. New in 2025, the unified “Smart Dashboard Builder” adds drag-and-drop filters powered by Apache ECharts, reducing dashboard build time by 30% according to user reports.
Data platform teams that need multi-tenant analytics on massive datasets, run on Kubernetes, and value Python extensibility will thrive with Superset.
Metabase ranks second for its intuitive “Ask a Question” interface, automated model suggestions, and 2025’s revamped Pulses for Slack & Teams. It offers click-through exploration without SQL, yet power users can write SQL or use the MetaBot AI assistant released this year.
Start-ups and product teams needing self-serve dashboards for non-technical stakeholders benefit from Metabase’s ease and minimal setup.
Lightdash places third by embedding a semantic layer on top of dbt models. The 2025 Metrics Explorer lets analysts define governed metrics once and reuse them everywhere, ensuring metric consistency across charts and dashboards.
Companies already invested in dbt that want governed metrics and version-controlled BI will love Lightdash’s Git-native workflow.
Yes. The OSS fork—maintained under the “redash-project” GitHub org—adds native DuckDB support and new alerting in 2025. Its lightweight query editor and shareable dashboards keep it popular with engineers needing quick insights.
Grafana’s Loki & Tempo backends made it observability royalty, but Grafana 11 (2025) bundles SQL data-source improvements, notebook-style panels, and business-chart templates, expanding its BI use. Its plug-in marketplace offers 100+ connectors.
Pentaho CE remains the most feature-rich ETL-plus-BI suite. The 2025 community build ships with a lightweight React dashboard designer and renewed support for Snowflake. The aging UI creates a learning curve, but enterprise ETL fans still rely on it.
BIRT 6.0 (2025) introduces a web-based designer, shedding its IDE dependency. It excels at pixel-perfect reporting for finance and manufacturing where PDF accuracy matters more than ad-hoc exploration.
GoodData.CN offers a headless, containerized analytics service with open-source core and commercial add-ons. Its 2025 “Logical Data Modeler” simplifies semantic modeling through YAML. REST and GraphQL APIs appeal to product teams embedding analytics.
Cube 0.35 (2025) adds WASM-based SQL transpilation for sub-second queries and an Authz SDK for row-level security. Developers use Cube to expose consistent analytic APIs to React, Vue, or Python apps.
SQLPad 8.0 remains a lightweight SQL IDE with charting. Its 2025 release ships with AI-assisted query hints and a Dark Mode UI refresh. Small teams wanting self-hosted query notebooks without heavyweight stacks choose SQLPad.
Choose Superset for massive scale, Metabase for non-technical users, Lightdash for dbt alignment, Redash for quick SQL sharing, Grafana for mixed observability/BI, Pentaho for ETL + BI, BIRT for pixel reports, GoodData.CN or Cube for headless embedding, and SQLPad for lean query work.
Galaxy is a modern SQL editor with an AI copilot and collaboration baked in. Pairing Galaxy with any BI tool accelerates query authoring, enforces SQL standards, and centralizes reusable logic before dashboards are built, boosting productivity across data teams.
Yes. Superset’s 2025 release introduces a Smart Dashboard Builder, fine-grained security, and performance improvements that keep it the most feature-complete OSS BI tool for large-scale deployments.
Metabase takes the crown for simplicity thanks to its "Ask a Question" UI, automatic data modeling, and 2025’s MetaBot AI assistant that converts natural language into charts.
Lightdash focuses on metrics governance on top of dbt, while Cube provides a headless analytics API for custom apps. Choose Lightdash for BI dashboards and Cube for embedding analytics via REST or GraphQL.
Galaxy’s lightning-fast editor and AI copilot speed up SQL authoring, enforce best practices, and centralize query sharing before you feed data into Superset, Metabase, or any BI layer—saving time and reducing errors.
