In their own words
Stacksync
Stacksync synchronizes CRM, ERP, SaaS, database, and warehouse data in real time, with two-way sync and configurable write direction. It lists more than 1,000 production-ready connectors, and almost all CRM, ERP, database, and warehouse connectors are bidirectional by default. Some sources, including billing event streams and observability platforms, are read-only by design. Workflows can react to record changes and be configured in a builder or as YAML/JSON files. Event queues process system events in order and support automatic retries. Stacksync AI agents can read and write the live data its syncs maintain. It offers API, self-hosted, and web options, with advanced transformations and reverse sync. The company says it encrypts data in transit and at rest and keeps no copy of records in the sync path after writes land. Starter costs $1,000 a month billed annually; a 14-day free trial is advertised without a credit card. Starter includes one active sync and 50K records in sync.
