Stacksync
What it is
Stacksync synchronizes CRM, ERP, SaaS, database, warehouse, and streaming-bus data in real time. Its two-way sync lets teams configure write direction, while almost all CRM, ERP, database, and warehouse connectors are bidirectional by default. The service lists 1,000+ production-ready connectors; some billing-event and observability sources are read-only. Workflows can react to record changes and be configured in a builder or YAML/JSON files. Ordered event queues support automatic retries, and AI agents can read and write live synced data. Stacksync is offered through API, self-hosted, and web options, with advanced transformations and reverse sync. It states that data is encrypted with TLS 1.2+ in transit and AES-256 at rest, with no record copy retained after writes land. Pricing starts at $1,000/mo billed annually, with a 14-day trial and no free plan.
