Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Slack Workflow Builder

  • Limited to Pro and above pricing tiers, requiring paid Slack subscription
  • Maximum 15 conditional branches per workflow, limiting complex logic paths
  • Connectors must be explicitly configured per integration type
  • No native web interface for non-Slack users

Zapier

  • The free plan allows 100 tasks per month and only two-step Zaps, one trigger and one action
  • Multi-step Zaps, filters, paths, webhooks and the formatter all require a paid plan
  • Premium app connectors are withheld from the free plan
  • Free Zaps poll for new data every 15 minutes against 2 minutes on Professional and 1 minute on Team
  • Paying monthly rather than annually costs 50 percent more, so the 2,000-task Professional plan is $73.50 a month instead of $49
