The record

Purpose: SQLStream monitors database queries and uses AI agents to analyze query patterns and produce reports with suggested fixes.
Analysis cadence: AI agents scan query patterns every five minutes for issues including N+1 queries, missing indexes, slow queries, and anomalies.
AI providers: The product supports OpenAI, Anthropic, and local Ollama, using a bring-your-own API key model.
Reports: Reports include SQL fixes, index recommendations, and performance projections.
Query monitoring: The live query stream displays queries as they execute and can be filtered by type, duration, database, or regex pattern.
Latency metrics: Latency histograms show P50, P95, and P99 by query fingerprint and compare baselines across deploys.
Explain plans: The product offers one-click EXPLAIN ANALYZE for captured queries.
Proxy: SQLStream is a single Go binary with connection pooling, TLS passthrough, and automatic reconnection; the page says applications can fall back to a direct database connection if the proxy fails.
Databases: The Pro plan supports PostgreSQL and MySQL.
Setup: The download instructions describe a single binary for macOS or Linux and say no Docker, dependencies, or SDK are required.
Security and privacy: The privacy policy says the proxy runs in the customer's infrastructure, sends anonymized metadata to SQLStream servers, and does not collect database table contents, credentials, connection strings, or query results.
Encryption and compliance: The privacy policy states that data is encrypted in transit with TLS 1.3 and at rest with AES-256, and describes its data handling as GDPR compliant.
Updates: The Pro purchase includes one year of updates.
Support contact: The site lists [email protected] as its contact email.
