Data Mirror vs PGSync

Data Mirror vs PGSync

The closest open-source alternative — minus the Kafka, plus monitoring

PGSync syncs PostgreSQL/MySQL to Elasticsearch and OpenSearch. Data Mirror does the same — plus Meilisearch, a built-in monitoring dashboard, and no extra services to run. One-time $49 licence.

Why Data Mirror

  • Meilisearch support — PGSync targets Elasticsearch/OpenSearch only
  • Built-in monitoring dashboard — pipeline health, throughput, latency, DLQ out of the box
  • Runs as a single Docker container — no external dependencies
  • Bulk initial snapshot plus CDC from the first run
  • One-time $49 licence with 6 months of support

Where PGSync wins

  • PGSync is free and open source — no licence cost
  • PGSync has a larger community and more battle-tested history
  • If you are already running Elasticsearch and want zero extra tooling, PGSync is a proven choice
