ReplAudit

ReplAudit is a web app (with optional lightweight desktop/agent installers) that continuously validates database replication by running controlled, low-impact “canary” writes and end-to-end read checks across primary and replicas. Instead of relying only on vendor lag metrics, it measures what actually matters: whether specific tables, transactions, and constraints replicate correctly under real workloads. It produces an auditable trail for incident reviews and compliance: when drift started, which objects were affected, and what the blast radius was. It supports common setups like PostgreSQL streaming replication, MySQL/MariaDB, SQL Server, and cloud-managed replicas via read-only connections plus a minimal write channel. It’s a traditional app with a small AI component that summarizes incidents and suggests likely root causes based on observed patterns (network jitter, replica IO saturation, long transactions).
