Comparisons anchored on Airbyte, the ELT platform whose core is under the Elastic License 2.0 while connectors are MIT, against open-source data loading tools.
Platform against CLI framework for ELT: Airbyte's Kubernetes-deployed platform and connector catalog against Meltano's Singer-based, Git-versioned projects, compared on licensing (ELv2 against MIT), deployment and how pipelines are managed.
A data movement platform against a Python library: Airbyte's UI, connectors and Helm deployment against dlt running inside existing code, notebooks or Airflow, compared on schema handling, incremental loading, licensing and operating effort.
Batch-style ELT replication against streaming CDC: Airbyte syncs to warehouses against Debezium's row-level change events through Kafka Connect, Debezium Server or an embedded engine, compared on latency, sources and infrastructure.
The three self-hosted ELT options data teams shortlist: Airbyte's platform, Meltano's CLI and dlt's library, compared on licensing, connectors, deployment model, state and schema handling, and who should run each.
