Kestra vs Zapier

Kestra is a declarative orchestration platform for building, running, and governing workflows across an organization. Workflows, called flows, are defined in YAML and can combine tasks, dependencies, conditions, triggers, and runtime parameters. Execution controls include retries, failure policies, timeouts, concurrency limits, worker assignment, and log capture. Kestra advertises more than 2,000 plugins for connecting to external tools, with examples including Airbyte, AWS, Azure, BigQuery, dbt, Docker, GitHub, Kafka, Kubernetes, Slack, Snowflake, and Terraform. A flow can orchestrate SQL, Python, shell, APIs, Terraform, dbt, Spark, and custom tools. The platform includes an MCP server for AI agents and supports exposing flows as callable tools. Teams can self-host with Docker or Kubernetes; Enterprise Edition also supports cloud, on-premises, and air-gapped environments. Setup instructions cover macOS, Windows, and Linux, alongside web and API platforms. Kestra Cloud advertises up to two months free during team setup. The Open Source and Enterprise Edition plans have no price listed.

Zapier connects apps through automated workflows called Zaps. Each Zap starts with a trigger and carries out one or more actions; a task counts when a successful action moves data or completes work. The service offers automation across more than 9,000 apps, with multi-step workflows, conditional logic and webhook triggers. The Free plan costs nothing and includes 100 tasks per month, unlimited Zaps limited to two steps, one user and a 15-minute polling interval. Polling for new data does not count toward tasks, but successful actions do. Without pay-per-task billing, workflows pause at the task limit until the next usage period. Professional starts at $19.99 per month and Team starts at $69.00 per month; both offer free trials. Team includes 25 users and shared Zaps, folders and app connections. Annual billing has a lower monthly fee, with a 33% saving shown in the pricing selector. Zapier is web-based and headquartered in San Francisco, California.
