Arq

PostgreSQL intelligence platform. Continuous detection, root-cause diagnosis, and resolution guidance for teams that need precision.

Arq detects problems in your PostgreSQL databases, explains why they happen, and tells you exactly how to fix them. It is not a dashboard. It is a diagnosis and guidance system that improves every database decision your team makes.

Arq runs continuously alongside your database, building context over time. Early on, it finds the obvious wins. Over weeks and months, it catches slow regressions, identifies configuration drift, and guides capacity decisions.

Three integrated surfaces

Detection, analysis, and resolution in a single platform.

Arq Signal

Always-on monitoring that groups correlated symptoms into single root-cause findings. Regression detection ties performance changes to specific deployments.

Arq Analyzer

Execution-based query analysis with planner misestimation detection, index recommendations, and workload profiling. Not just EXPLAIN plans.

Arq Workbench

Interactive workspace for investigation and verification. Compare plans, test index changes, and confirm improvements before deploying to production.

Key capabilities

--Root-cause grouping: correlated symptoms surfaced as a single finding, not separate alerts
--Regression detection tied to specific deployments, schema changes, or config updates
--Execution-based analysis using actual row counts, buffer hits, and timing
--Targeted recommendations with projected improvement, not generic best practices
--Before/after verification so you know the fix works before it ships
--On-premise deployment: your data stays in your network

Deployment

Arq runs in your infrastructure. It connects to PostgreSQL using read-only credentials via the standard protocol. No agents to install on database hosts, no schema changes, no sidecar processes.

Designed for environments subject to SOC 2, PCI DSS, and financial regulatory requirements. Query text and result data never leave your network.
