Kestra

Kestra is worth adding because it covers a broader orchestration shape than many workflow tools in the catalog. The official docs position it as an open-source, infinitely scalable orchestration platform for business-critical workflows defined declaratively in code. That is important because Kestra is not limited to data pipelines. It spans dbt orchestration, microservices, infrastructure tasks, manual approvals, and scheduled or event-driven automation, which makes it a real platform choice rather than just another pipeline runner.

Its pricing page is also clear enough to describe responsibly. Kestra Open Source is free under Apache 2.0. The commercial plans are Team, Pro, and Enterprise, sold on an annual subscription and per-instance basis, with unlimited flows, tasks, and executions. Kestra does not publish list prices for those paid tiers, but it is explicit about the packaging model and about what becomes commercial: governance, multitenancy, worker groups, secret management, plugin controls, and broader platform capabilities.
