What Stacksync is
Stacksync synchronizes data in real time across CRM, ERP, SaaS, database, and warehouse systems. It supports two-way sync with configurable write direction and lists more than 1,000 production-ready connectors. Almost all CRM, ERP, database, and warehouse connectors are bidirectional by default, while some sources, including billing event streams and observability platforms, are read-only by design. Workflows can trigger actions when records change and can be configured in a builder or as YAML or JSON files. Event queues process system events in order and can retry them automatically. Its AI agents can read and write the live data maintained by its syncs. Stacksync says it encrypts data in transit with TLS 1.2+ and at rest with AES-256, and retains no copy of records in the sync path after writes land. Paid plans start at $1,000/mo billed annually, and the homepage advertises a 14-day free trial with no credit card. Starter includes one active sync and 50K records in sync.
