NexSync keeps your databases, SaaS tools, and data warehouses in perfect sync — with sub-200ms latency, automatic schema handling, and a developer experience that doesn't make you angry.
Four phases. Minutes to set up. Runs forever.
Choose from 150+ pre-built connectors. Authenticate with OAuth, API keys, or database credentials — all stored in our encrypted vault. Most connections take under 60 seconds.
Log-based CDC that reads directly from your database transaction log. Zero performance impact on your source. Every insert, update, and delete — captured instantly.
True two-way sync with field-level conflict resolution. Define merge strategies per table. Audit every decision. Never lose data when both sides update simultaneously.
Sources change without warning. NexSync detects schema changes, adapts transformations automatically, and notifies you — instead of silently breaking or hard-stopping.
Drag-and-drop pipeline construction with inline transformation logic. Or declare everything in YAML and manage it through Git. Both are first-class experiences.
Per-event metrics, lag monitoring, throughput graphs, and anomaly detection built into the platform. Connect to Datadog, Grafana, or your own stack via OpenTelemetry.
Durable event buffering with configurable retention. Dead-letter queues, automatic retry with exponential backoff, and point-in-time replay for any pipeline.
Pre-built, maintained, and tested by our team. New connectors ship every two weeks.
Every pipeline is a file. Version control your entire sync configuration. Use our Terraform provider, CLI, or REST API from any CI/CD system.

"The bidirectional sync between Salesforce and our internal Postgres was the hardest problem we'd been putting off for 18 months. NexSync solved it in an afternoon."
"We evaluated Fivetran, Airbyte, and NexSync. NexSync was the only one that genuinely handled our Kafka-to-Snowflake pipeline without custom middleware."
All paid plans include a 14-day free trial, no credit card required.

NexSync is purpose-built for real-time, bidirectional sync — not just one-way ELT batch pipelines. We support log-based CDC (not query polling), native bidirectional conflict resolution, and schema drift handling that propagates changes automatically rather than halting your pipeline.
It means the median time between a transaction committing in your source database and the corresponding event arriving at your destination is under 200 milliseconds. This is measured end-to-end including network transit, not just within our infrastructure.
Enterprise plans include a private VPC deployment option where we run NexSync infrastructure inside your cloud account (AWS, GCP, or Azure). Your data never leaves your environment. Contact our sales team for architecture details.
Growth plans include 50M rows/month. If you exceed this, we charge $0.40 per additional million rows — no surprise invoices, we notify you at 80% and 95% of your limit. Enterprise plans are priced on committed volume with custom rates.
