Windmill vs Zapier Plus

Windmill's Free and Open-source edition is $0/month for self-hosted use with unlimited executions, while Enterprise starts at $120/month with unlimited workspaces and uncapped SSO seats, priced further by developer/operator seats and compute units.

Zapier offers a Free plan with 100 tasks per month at no cost. The Professional plan starts at $19.99 per month (billed annually) for 750 tasks, with pricing scaling up based on task volume. The Team plan starts at $69 per month for 2,000 tasks. Enterprise plans are custom priced. Annual subscriptions receive 33% off compared to month-to-month billing.

The free self-hosted plan supports unlimited executions but caps SSO at 10 users, workspaces at 3, groups/permissions at 4, and email triggers at 100 per day.

Each trigger and action pair in a Zapier workflow counts as one task. For example, a 5-step Zap that runs 1,000 times per month uses 5,000 tasks. If you exceed your plan's task limit, you can enable pay-per-task overage pricing. At higher volumes, Zapier can cost significantly more than competitors like Make or n8n.

Enterprise usage is metered through seats (developer seats at $20/month, operator seats at $10/month) and compute units, e.g. $100/month for 2 standard-worker compute units.

The Free plan includes 100 tasks per month, unlimited Zap workflows, unlimited Tables and Forms, two-factor authentication, and basic AI features. However, it is limited to simple 2-step Zaps (one trigger, one action), no webhook support, 15-minute polling intervals for trigger checks, and only 2,500 records in Tables.

The pricing page addresses this directly as an FAQ topic, noting that self-hosted applications built on the open-source edition can continue running independently of Windmill the company.

Zapier supports integration with over 7,000 applications and services, including all major SaaS platforms such as Salesforce, HubSpot, Slack, Notion, GitHub, Stripe, Xero, and QuickBooks. This extensive app library is one of Zapier's main competitive advantages.

Professional and higher plans support webhooks, allowing data from apps without native Zapier integrations. Multi-step Zaps support conditional paths, filters, and approval workflows. Code steps allow custom JavaScript or Python logic for advanced automation. The free plan does not support webhooks.

Zapier's linear workflow builder struggles with deeply nested conditions and multi-outcome branching logic. As a third-party orchestration layer, Zapier adds latency compared to native integrations. Free plan polling is every 15 minutes, limiting real-time responsiveness. For high-volume automation (10,000+ tasks/month), Zapier becomes significantly more expensive than alternatives.
