PGSync Pro builds on the open-source PGSync tool to sync data from PostgreSQL, MySQL, and MariaDB into Elasticsearch or OpenSearch in real time. It adds intelligent semantic and hybrid search capabilities that monitor for meaning changes before triggering expensive embedding operations. The system treats your database as the single source of truth while maintaining a fresh vector index for semantic search. It is designed for developers who need production-grade, self-hosted search infrastructure without sending sensitive data to external services.
PGSync Pro sits in PulseGate's Frameworks & SDKs category. It focuses on keeping a fresh, up-to-date vector index in Elasticsearch that only re-embeds documents when their semantic meaning actually changes without data leaving your infrastructure. PGSync Pro is an open-source project aimed at developers. Pricing is paid. The product ships for the web, embeddable surfaces, the command line, and API, and it can be self-hosted.
Behind PGSync Pro is toluaina, based in the United Kingdom, and the product first shipped in 2019. The project is developed in the open on GitHub with 1.4k stars and 13 commits in the last 90 days. Among its 6 catalogued features are Real-time Sync, Semantic Search, and Change Data Capture. It exposes integrations via a public API.
