DriftLedger

DriftLedger is a web app (with a lightweight desktop agent) that continuously validates database replication correctness, not just lag. It compares source vs replica at the row and schema level using sampling and targeted checks, then pinpoints exactly where drift starts (table, primary key range, transaction window). It supports common setups like Postgres streaming replication, MySQL replicas, and logical replication pipelines (e.g., Debezium/Kafka) by reading WAL/binlog metadata plus periodic consistency probes. Alerts are actionable: it tells you whether the issue is missing writes, out-of-order events, schema mismatch, or replica apply errors, and suggests the safest remediation steps (re-sync table, rebuild slot, fix DDL ordering). It also produces audit-ready reports showing replication health over time, useful for compliance and incident postmortems. This is a combination traditional + AI app: AI summarizes incidents and recommends playbooks, but core detection is deterministic.
