Strata

Product: Strata is a semantic layer platform for self-service BI and warehouse access, turning database tables into a governed business-ready model for data exploration without SQL.
Modeling: Semantic models define business-friendly fields, metrics, and relationships in YAML, with changes tracked through migrations and Git.
Query routing: Strata routes queries across a warehouse and fast OLAP tiers to a datasource that can satisfy them.
BI: The product includes self-service dashboards with automatically laid out views, report subscriptions, scheduled reports, and a Google Sheets add-on that refreshes results in place.
AI agents: Users can build agents on the governed semantic model, inspect and edit their queries, and share agents with their team.
Agent security: Agents inherit row-level security and masking, and can use only the governed measures and dimensions in the model.
Integrations: Documented datasource adapters include PostgreSQL, Snowflake, MySQL, SQL Server, Athena, Trino, DuckDB, Druid, ClickHouse, Databricks, SQLite, and Redshift.
API: Strata documents a REST API for metadata discovery and query execution, with requests validated against semantic fields.
Deployment: Strata Server is a self-hosted web application distributed as a private container image, with deployment guides for quick install, production, and AWS ECS.
Security: The privacy policy says Strata uses encryption, firewalls, and SSL technology as security measures, while noting that these do not guarantee protection from breaches.
Support: Free includes email support with a 3-day response, docs, and community; Team aims for a 24-hour response; Enterprise support is custom.
Audience: Strata is aimed at teams opening warehouse data to non-technical users and AI agents; its pricing page says it is not intended as another query tool for SQL-fluent analysts.
Company: The maker identifies itself as Strata Business Intelligence, LLC and lists its address in Vienna, Virginia.
Price from: Free
