The short version

  • Only React has a free tier, so it costs nothing to try first.
  • Each has a real cost: React jSX requires a build step using Webpack, Babel, or other transpilers to convert to browser-executable JavaScript; Slack Workflow Builder limited to Pro and above pricing tiers, requiring paid Slack subscription
  • They diverge on capability: React covers Component-based architecture, Slack Workflow Builder covers Workflow builder.

React

  • JSX requires a build step using Webpack, Babel, or other transpilers to convert to browser-executable JavaScript
  • Routing and state management are separate dependencies, not included in core library
  • Configuration complexity for advanced features like server-side rendering without a meta-framework
  • Requires choosing and configuring build tools and development environment setup

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
