Relay.app is the hybrid AI workflow pick that blends AI steps with human-in-the-loop approval gates. Founded 2022 in San Francisco and backed by Tiger Global and Khosla Ventures. Around 50,000-plus users by Q4 2024. The wedge for free readers: Free tier ships 200 workflow steps monthly with 50-plus integrations and explicit support for steps requiring human review before continuing. No other catalog pick designs around approval gates at the free tier.
Free ships 200 workflow steps a month with the integration library and AI plus human-in-loop steps. Professional is the upgrade tier at nine dollars per user monthly with five thousand steps and premium AI models. Team adds 25K steps plus shared workflows and roles. Free readers run small personal approval workflows indefinitely; the upgrade hits when step count or team size grows.
The trade-off versus Lindy is autonomous-only versus approval-gated; Relay.app is intentionally human-supervised where Lindy runs autonomously by default. The trade-off versus n8n is workflow complexity; Relay.app is purpose-built for human-supervised steps where n8n handles general automation. For free readers running business processes that require human oversight, Relay.app fits cleanest.
