Query S3 without building around Athena and Glue
Map S3 buckets, Iceberg, S3 Tables, and Glue catalogs into one SQL runtime. Query in place, federate with warehouses, and expose governed access to BI and agents.
Query S3 directly
Map Parquet, CSV, JSON, Iceberg, S3 Tables, and Glue-backed catalogs into a live SQL namespace. No warehouse copy required first.
Query in place
Map bucket paths and query them with the same engine as managed catalogs.
Open table formats
Parquet, CSV, JSON, Iceberg, S3 Tables, Iceberg REST.
Glue catalog support
Connect Glue as an Iceberg REST catalog when it owns metadata.
Federated joins
Join S3 data with Postgres, warehouses, and managed lakehouse tables.
Interactive queries
Workers and caching for repeatable exploration, not one-off scans.
Agent access via MCP
Governed lakehouse access through MCP. No bucket credentials or exports.
What you get
S3 stays the storage layer. Altertable adds execution, federation, and governance.
Fewer copies
Query mapped object-storage data in place.
One SQL namespace
S3, warehouses, and operational databases in the same queries.
Repeatable analysis
Dashboards and apps on live data, not one-off Athena scans.
Governed agent access
Agents query through MCP, not raw bucket access.
Explore the rest of the platform
More workloads on the same engine, governance, and pricing.
AI Context
Give Claude, GPT, and other agents governed access to trusted data, metrics, and business context. Agents work from the same definitions and permissions as your team.
Tools & Integrations
Plug Altertable into BI, notebooks, SQL clients, and agents through open standards like Iceberg, Parquet, the Postgres wire, Arrow Flight, and MCP. Adopt it alongside your stack instead of replacing it.
Query S3 from one runtime
DuckDB workers on open formats, federated SQL across your existing systems,
and an MCP server for agents — at flat monthly pricing.
