Answered from the vendors’ own pages

Slack Workflow Builder: Is Slack Workflow Builder included in all Slack plans?

No, Workflow Builder is only available in Slack Pro, Business+, and Enterprise plans. It is not included in the Free plan.

Source
Zapier Plus: How much does Zapier cost and what is included in each plan?

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.

Source
Slack Workflow Builder: Can Workflow Builder connect to external applications?

Yes, Workflow Builder supports connectors that translate actions in Slack to instant results in third-party tools, allowing workflows to interact with your full application stack.

Source
Zapier Plus: What is a task in Zapier and how much does it cost if I exceed my plan limit?

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.

Source
Slack Workflow Builder: What is the maximum complexity of Slack Workflows?

Workflows support conditional logic with up to 15 conditions, enabling complex decision paths for automation.

Source
Zapier Plus: What can I do with Zapier's free plan?

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.

Source
Zapier Plus: How many apps and integrations does Zapier support?

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.

Source
Zapier Plus: Does Zapier support webhooks and advanced workflow features?

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.

Source
Zapier Plus: What are Zapier's limitations for complex automation scenarios?

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.
