CData Sync vs drt

CData Sync replicates data from databases, SaaS applications and APIs to databases, data lakes and data warehouses. CData says it supports over 250 sources and offers a catalog of cloud and on-premises destinations. Pipelines can use incremental loading and, for supported sources, real-time Change Data Capture. ETL and ELT transformations are available through SQL or dbt Core and Cloud. Users can schedule pipelines and receive email, Slack or Teams notifications when workflows finish or fail. Sync can run on premises, in cloud environments or through CData-hosted Sync Cloud, and is listed for Linux, Windows, web, API and self-hosted use. Its APIs and scripting can manage connections and jobs, inspect status and history, download logs, and run custom behavior around jobs. It can adjust destination schemas when source schemas change; its overview says it does not delete destination columns or reduce their size. CData documents TLS/SSL encryption and encrypted sensitive configuration values and reports third-party SOC 2 Type II and ISO/IEC 27001:2022 audits. A 14-day trial is available; there is no free plan.

drt is a free reverse ETL tool for moving modeled warehouse data into team tools. Teams define syncs in YAML, version them in Git, install drt-core with pip, and run jobs from the terminal. A dry run with a diff previews rows due to be added, updated, or deleted before writing. The project lists 13 sources and 34 destinations, including BigQuery, Snowflake, Postgres, Slack, and Salesforce, across warehouses, SaaS APIs, cloud storage, files, and webhooks. drt can read dbt projects and use `ref()` models to follow model lineage. Its listed orchestration integrations include Dagster, Prefect, Airflow, and a dbt manifest reader; a GitHub Action supports scheduled or event-triggered syncs. An optional MCP server lets compatible clients validate configuration, run syncs, list them, and inspect status. Data moves directly from the user's warehouse to the destination without a drt-hosted intermediary. Syncs are batch-based, the core is self-hosted, and the project is licensed under Apache 2.0. RBAC, audit logging, plugins, and managed cloud hosting are outside drt-core.
