Redash

Redash is a browser-based analytics tool for exploring, querying, visualizing, and sharing data from many data sources. It helps SQL users build reports and gives other people in the organization a way to use those results through shared links and dashboards.

It includes a query editor with schema browser and auto-complete, drag-and-drop visualizations, dashboards, scheduled refreshes, alerts, and a REST API. It supports SQL and NoSQL queries and can connect to more than 35 data sources, including Amazon Athena, BigQuery, Databricks, MySQL, PostgreSQL, Redshift, Snowflake, and SQLite.

Redash is open source under the BSD-2-Clause license and self-hosted. Setup is documented with ready-made AWS and GCE images, and an extensible data source API lets you add support for sources beyond the built-in list.
