Zapier

Zapier is the absolute, unquestioned, and globally ubiquitous titan of the "Consumer and Small Business Workflow Automation" sector. While MuleSoft is for massive Java developers connecting Oracle mainframes, Zapier completely democratized integration for the average internet user. It is the digital duct tape that holds the modern internet together, boasting the largest app ecosystem on earth (6,000+ apps). The absolute core differentiator of Zapier is its "Extreme Accessibility and Massive App Directory." A freelance marketer with zero coding knowledge can log in, click a button, and build a 'Zap': "When a new lead fills out a Facebook Ad Form, automatically add their email to Mailchimp and send me an SMS text message." It takes 30 seconds to build. Because it completely eradicated the barrier to entry for software integration, offering an incredibly generous free tier and flawless integrations with almost every SaaS tool in existence, Zapier is the inescapable standard for freelancers, marketing agencies, small businesses, and massive corporate 'shadow IT' departments looking for a quick fix.
