In their own words
PrestoDB
PrestoDB is a free, open-source distributed SQL query engine for querying large data sets across different kinds of data systems. Connectors access sources through a standard API, with documented options including Hive, Iceberg, Kafka, Cassandra, MongoDB, MySQL, PostgreSQL, BigQuery, Redshift, and SQL Server. Queries run across a coordinator and worker nodes. The project provides a server tarball, command line interface, JDBC driver, and Docker container, with deployment guidance for Docker, Helm, and Homebrew. Presto documents Kerberos, LDAP, password-file, and OAuth 2.0 authentication, plus access control and secure internal communication; SSL/TLS can protect communication between cluster nodes. It is self-hosted and governed as an independent open-source project under the Linux Foundation. The documentation cautions that SQL familiarity does not mean Presto includes the features of a standard database. The project directs users to its Slack community to connect with engineers and other users. The listed current release is version 0.299, dated August 31, 2026.
Query Streams
Query Streams gives spreadsheets, AI clients, apps, and scheduled syncs governed access to databases and APIs through an outbound-only Network Agent. Nova AI accepts plain-English questions, reads a database schema, runs read-only SQL, and returns metrics, tables, and charts. A hosted MCP server connects sources to Claude, Cursor, ChatGPT, and Grok using a revocable key. Excel and Google Sheets add-ins run shared saved queries and stream live results into cells without exposing SQL to recipients. Federated queries join data from multiple databases and API sources in one SQL statement. Scheduled results can be sent to supported services as often as every five minutes. The Network Agent makes an encrypted outbound connection, needs no inbound ports or VPN, restricts queries to SELECT, WITH, and EXPLAIN, and keeps database credentials on the user's network. The Free tier is free and includes 5 MB/month query traffic; paid plans start at $15 a month. New accounts receive a 30-day trial with every feature unlocked and no credit card.
