Open-source Power BI alternatives

Apache Superset is a data exploration and visualization platform that runs as a web application. Analysts and business users can connect it to a database, build charts without code, assemble them into dashboards and share them, so it can augment or replace proprietary business intelligence tools for many teams.

The no-code chart builder sits next to a web-based SQL editor for advanced queries, and a lightweight semantic layer lets teams define reusable dimensions and metrics. Visualizations range from simple bar charts to geospatial views. Superset can query any SQL datastore or engine provided a matching Python database driver and SQLAlchemy dialect exist, including Presto, Trino and Athena. A configurable caching layer reduces database load, and security roles and authentication options are extensible.

The stack is Python with Flask on the back end and React on the front end, under the Apache-2.0 license. A REST API and extension framework allow programmatic control and customization. Documentation is split into guides for users, administrators and developers, and it is a typical choice for organizations that want a self-managed BI layer.

Metabase is an open-source business intelligence and embedded analytics tool meant for everyone in a company, not only analysts. People can ask questions about their data without knowing SQL, while an SQL editor is available for more complex queries. Written in Clojure, it connects to databases such as PostgreSQL and MySQL.

Its features include interactive dashboards with filters, auto-refresh and custom click behavior, plus documents for long-form analysis that colleagues can comment on. An AI assistant called Metabot helps answer questions and write queries, and you can build your own AI agent against your data. Data Studio supports transforming raw data into analytics-ready tables and defining canonical metrics. Alerts and scheduled dashboard subscriptions go to email, Slack or a webhook, and a Library plus Git integration help version your work.

Metabase can also be embedded in your own product with components for charts, dashboards, a data browser and AI chat, and granular permissions work for internal teams and embedded customers. You can self-host it or use Metabase Cloud, which the project says includes support, backups, upgrades and a free trial. The repository license is listed as 'Other', so review its terms.

Redash is an open-source business intelligence and data exploration tool that works entirely in the browser. SQL users connect it to a data source, write queries, turn results into visualizations and share them, so that colleagues without SQL skills can use the results too.

The query editor accepts both SQL and NoSQL queries and offers a schema browser plus auto-complete. Visualizations are built by drag and drop and can be combined into dashboards, and every chart or query has a shareable URL that supports collaboration and peer review. Charts and dashboards can refresh on a schedule, and alerts can notify you when results cross a threshold. Topics mention many sources, including Redshift, BigQuery, Athena, MySQL, PostgreSQL and Databricks.

Redash is written in Python and JavaScript and licensed under BSD-2-Clause. You deploy it on your own infrastructure, commonly with Docker, and it is aimed at analysts and engineers who want a lightweight, query-first dashboard tool rather than a heavy BI suite.

DataEase is an open-source BI tool that helps users analyze data and spot business trends. It connects to a wide range of data sources, lets you build charts by dragging and dropping, and supports sharing results with others. The project describes itself as an open-source alternative to Tableau and is developed by FIT2CLOUD in Java, with a Chinese-language README.

Supported data sources include OLTP databases such as MySQL, Oracle, SQL Server, PostgreSQL, MariaDB, Db2, TiDB and MongoDB, OLAP engines such as ClickHouse, Apache Doris, Apache Impala and StarRocks, Amazon Redshift, Excel and CSV files, and API sources. The stack uses Vue.js, Spring Boot, AntV for charts, Apache Calcite and SeaTunnel, and Docker. Installation uses an offline package on a Linux server with at least 2 cores and 4 GB of memory, or the 1Panel app store. V3 uses the FIT2CLOUD Open Source License, essentially GPLv3 with extra restrictions, and commercial licensing is available.

Evidence is a code-first business intelligence tool, released as open source, offered in place of drag-and-drop BI products. Reports and dashboards are written as Markdown with SQL queries, which keeps them in version control and lets analysts build interactive data visualizations without a point-and-click builder.

The README calls it agent-ready: you can develop with Evidence's own agent, or locally with coding assistants such as Claude Code or Cursor. Topics mention dbt, DuckDB, Svelte, Tailwind CSS, WebAssembly and self-hosting. A project is created from an installer for macOS, Linux or Windows, and the result can be published on Evidence Studio for hosted reports, or built as a static site and self-hosted on your own infrastructure.

Evidence is written in TypeScript with Svelte and licensed under MIT, and has a Slack community for help. It suits data teams and analysts who are comfortable with SQL and want reports reviewed and deployed like software, rather than assembling dashboards in a GUI.

Lightdash is an open-source business intelligence platform that it describes as agentic BI, meant for data teams that want analytics to be shipped like software. Metrics, joins, permissions, business logic and caching are defined once in a context layer, and that layer feeds MCP, SDKs, embedded analytics, data apps, AI agents and dashboards.

Analytics can be built as code: metrics, charts and dashboards live as files that you can edit with coding agents, preview from the Lightdash CLI, validate in CI and review in pull requests. Business users can pose questions in plain English, browse dashboards or build custom data apps, all while governance stays in place. Agents answer from the context layer rather than guessing from raw tables, respect permissions and return queries that can be inspected. The repository topics mention dbt.

Lightdash is written in TypeScript. The vendor recommends starting with Lightdash Cloud, which needs no infrastructure to run, and also offers a live demo, documentation and a sales call. The repository lists its licence as other, so check the terms before self-hosting.

Chartbrew is an open-source web application that connects directly to databases and APIs and uses the data to build charts and dashboards. Its tools include a chart builder, editable dashboards, embeddable charts, a query and request editor and team features for sharing reports.

The platform also includes an AI assistant and scheduling, and its topics reference MySQL, PostgreSQL, MongoDB, Firestore and Firebase as data sources, with the latest list of supported sources on the project website. To self-host, the README lists Node.js 22 or newer, MySQL 5 or PostgreSQL 12.5 or newer, and Redis 6 or newer as prerequisites. The front end uses React and the back end Node.js.

A hosted Chartbrew service is available, and the repository license is listed as 'Other' on GitHub, so check the terms for your use. Chartbrew suits agencies, startups and teams who want shareable client dashboards without building a BI stack.

Saiku began in 2010 as an open-source OLAP browser for Mondrian and was rebuilt in 2026 as a modern semantic layer for analytics. It defines business cubes once and then exposes them to different consumers: a drag-and-drop browser interface, Excel through MDX and XMLA, dashboards, and AI agents through MCP.

In the browser, users drag fields onto rows, columns and filters and the application writes MDX for them. The back end uses a fork of Mondrian 4.8 with an Apache Calcite-based SQL planner, which can reach modern engines such as lakehouse systems. A typed REST interface allows AI agents to query data without handling MDX. A demo mode ships with a self-contained H2 database and the FoodMart sample cube.

Saiku is written in Java and licensed under Apache-2.0. It runs from a Docker image, which runs as a non-root user and requires setting an admin password for real deployments, and a hosted demo instance resets nightly. It suits analytics and BI teams that need governed, reusable metric definitions across spreadsheets, dashboards and AI tools.

Shaper is an open-source tool for building data dashboards, reports and customer-facing analytics by writing SQL. It is developed by Taleshape and powered by DuckDB, and it aims to make analytics simple for developers: you write queries, and Shaper turns them into charts and shareable pages.

The data visualization side is SQL-first and designed to work with AI, with a Git-based workflow and the ability to query across data sources. Embedded analytics features include white-labeling and custom styles, row-level security through JWT tokens, and embedding via JavaScript and React SDKs without an iframe. Automated reporting can generate PDF, PNG, CSV and Excel files, send scheduled alerts and reports, and share password-protected links.

Shaper is written in Go and licensed under MPL-2.0. You can try it with a single Docker command or follow the deployment guide for production. Taleshape also offers managed hosting, in its own cloud or in your infrastructure, plus hands-on support, and explains the shared-responsibility model between self-hosting and managed service. It suits product teams adding analytics to their apps.

Frappe Insights is an open-source business intelligence tool that aims to make data analysis and reporting accessible to both technical and non-technical users. It grew out of the experience of working with Frappe Framework applications, where building structured data was easy but extracting reports usually required SQL knowledge.

You can connect multiple sources, including databases, files and spreadsheets, and use a step-by-step query builder to select tables, add joins, apply filters and calculations without writing SQL. Results can be visualized with various charts, with the tool suggesting a fitting chart, and dashboards are assembled by drag and drop with dashboard filters. Supported databases include MySQL, PostgreSQL, DuckDB and BigQuery. A SQL editor is also available.

Insights is built on the Frappe Framework, Frappe UI with Vue, and the Ibis library for composing SQL with dataframe APIs. It is written in Python, licensed under AGPL-3.0, and can be self-hosted, with a live demo and documentation. It suits ERPNext and Frappe users as well as teams wanting a lightweight BI tool.
