Gumloop vs Relay.app (2026)
Overview
Gumloop is an AI-native workflow automation platform often called the "AI Zapier." It lets users build complex AI automations visually — chaining LLM calls, web scraping, data processing, and API integrations into multi-step workflows. Designed from the ground up for AI use cases rather than retrofitting AI onto traditional automation.
Relay.app is a collaborative workflow automation platform built around human-in-the-loop AI. It combines traditional automation with AI steps and human approval gates, letting teams build workflows where AI handles the bulk of work but humans review and approve critical decisions. The leading choice for teams that need AI automation with oversight.
