Stacksync
Stacksync synchronizes data across CRM, ERP, SaaS, database, and warehouse systems in real time.
What Stacksync is
Stacksync synchronizes data across CRM, ERP, SaaS, database, and warehouse systems in real time. Its two-way sync supports configurable write direction, and it lists more than 1,000 production-ready connectors. Almost all CRM, ERP, database, and warehouse connectors are bidirectional by default, while some sources, such as billing event streams and observability platforms, are read-only. Workflows can respond to record changes and be set up in a builder or as YAML/JSON files. Event queues process events in order and can retry them automatically. Its AI agents can read and write the live data maintained by its syncs. Stacksync is available through API, self-hosted, and web options, with advanced transformation support and reverse sync. Starter is aimed at startups and growing teams; higher plans add capacity and support, while Enterprise includes options such as SSO and SCIM.
