Zapier connects over 6,000 apps so that an event in one triggers an action in another. A new form response can create a Trello card, a Stripe payment can update a spreadsheet, a GitHub issue can post to Slack. Each connection is called a Zap, and you build them with a visual editor and no code.

For developers who want to offload routine automation to non-technical teammates, it removes the need to build custom integrations for every tool. The free tier allows a limited number of Zaps and tasks per month. More complex workflows with filters and multi-step logic require paid plans. It is one of the most widely used automation platforms for a reason.
