Spec score 7.4 #22 of 28 in Semantic Layer Software

What it is

Strata turns database tables into a governed semantic model for self-service BI and warehouse access, so users can explore data without SQL. Teams define business-friendly fields, metrics, and relationships in YAML, with model changes tracked through migrations and Git. Query routing sends requests to a suitable datasource across a warehouse and fast OLAP tiers. The product includes dashboards with automatically laid out views, subscriptions, scheduled reports, and a Google Sheets add-on that refreshes results in place. Teams can also build agents on the governed model, inspect and edit their queries, and share agents; these inherit row-level security and masking and are restricted to modeled measures and dimensions. A REST API handles metadata discovery and query execution validated against semantic fields. Documented adapters include PostgreSQL, Snowflake, MySQL, SQL Server, Athena, Trino, DuckDB, Druid, ClickHouse, Databricks, SQLite, and Redshift. Strata Server is a self-hosted web application distributed as a private container image. The Free plan costs nothing and includes one developer, 25 users, and two data sources per project; Team and Enterprise prices are custom or unlisted.
