SQLStream

What SQLStream is
SQLStream is a self-hosted tool for monitoring database queries and using AI agents to identify patterns that may affect performance. Its agents scan every five minutes for N+1 queries, missing indexes, slow queries, and anomalies, then produce reports with suggested SQL fixes, index recommendations, and performance projections. A live query stream shows queries as they execute and can be filtered by type, duration, database, or regex pattern. Latency histograms show P50, P95, and P99 by query fingerprint and compare baselines across deploys; captured queries can be opened in a one-click EXPLAIN ANALYZE. The product runs as a single Go binary with connection pooling, TLS passthrough, and automatic reconnection. Its proxy runs in the customer's infrastructure and sends anonymized metadata to SQLStream servers; the privacy policy says it does not collect database contents, credentials, connection strings, or query results. Data is encrypted in transit with TLS 1.3 and at rest with AES-256. Pro supports PostgreSQL and MySQL and costs $299, paid once, including one year of updates.
