Why it matters for a GTM stack

Per-task automation pricing grows with volume: Zapier's Professional plan lists 2,000 tasks at $49/mo and 100,000 at $489/mo (annual billing, pricing page fetched 2026-10-31). A RevOps team that already runs lead routing, enrichment syncs and CRM hygiene jobs at volume can move the heavy, predictable flows to Kestra and keep them reviewable in Git. Keep the long tail of one-off app connections where they are; move the expensive, high-volume jobs first.
