Airbyte

Airbyte is a data integration platform that moves data from your many sources — databases, SaaS apps, APIs, files — into your data warehouse, lake, or other destinations, so it can be analyzed in one place. It follows the modern ELT approach (extract and load first, transform later in the warehouse) and is best known for being open-source with a very large, community-driven catalog of connectors, which means broad coverage and the ability to add or customize connectors yourself.

Airbyte comes in flavors: the open-source Core edition is free to self-host (you provide the infrastructure), while Airbyte Cloud is a managed service with usage-based pricing, plus Teams and Enterprise tiers for scale, governance, and support. It handles incremental syncs, scheduling, normalization, and works with the rest of the modern data stack (dbt for transformation, warehouses like Snowflake and BigQuery). Its open-source roots and connector breadth make it a go-to for data teams who want control and to avoid per-connector vendor lock-in.

Airbyte suits data engineers and teams building a modern data stack who want flexible, ownable data pipelines, especially those who value open-source and a wide connector catalog. Pricing ranges from free self-hosting to usage-based cloud and capacity-based enterprise, so cost depends on whether you self-host and how much data you sync.
