AddaxA stable and efficient heterogeneous data sync tool

Define read → transform → write as a single JSON job, and operate it like an engineering artifact

Quickstart

Observability for data quality

Strong typing + stats reports help you quickly separate data issues from configuration issues.

Open stats report

Built-in transforms (plus Groovy)

Mask, filter, enrich, and cast types with built-in transformers, or write Groovy for custom logic.

Learn transforms

Operable, high-throughput sync

Define the job once, run via CLI anywhere—ideal for CI/CD, schedulers, and standardized operations.

Start with job setup

One JSON file. That's all it takes.

Declare reader and writer plugins in JSON — no code needed to sync data between heterogeneous sources.
