Relay.app is a no-code workflow automation platform with built-in AI steps and human-in-the-loop approvals, aimed at operations and business teams who want Zapier-style automation but with a safety checkpoint before an AI agent takes a risky or irreversible action.
Who it's for
Relay.app fits small-to-midsize teams — ops, marketing, sales, customer support — that already think in terms of triggers and actions across everyday SaaS tools and want to add AI without giving it free rein. It's a good match for anyone burned by fully autonomous automation making the wrong call, since Relay.app is built around letting a human review and approve a step before it runs. Teams that want deep, code-first agent frameworks or need thousands of niche integrations will find better fits elsewhere.
How it works
You build a workflow from triggers (event, schedule, manual, webhook, or email) and a chain of actions across 200+ native integrations such as Gmail, Notion and HubSpot. AI steps can draft content, classify data, or make decisions inside the flow, and human-in-the-loop checkpoints let a teammate approve, edit or reject an AI-proposed action — for example, approving a drafted customer reply before it sends. For the AI steps, Relay.app supports bring-your-own-API-key model access, so you can choose and pay for the underlying LLM provider directly rather than relying solely on Relay.app's markup.
Pricing
Relay.app has a free plan and paid plans starting from roughly $19 per month (Professional tier, billed annually), with a Team plan and custom Enterprise pricing above that; billing is usage/task-based as you scale. Because pricing tiers and included steps/credits change over time, check Relay.app's current pricing page before committing to a plan.
Strengths and trade-offs
The standout feature is human-in-the-loop design: rather than trusting an agent to always get it right, Relay.app builds a pause-and-approve step directly into the workflow, which makes it a comfortable entry point for teams nervous about autonomous AI touching customer-facing or financial actions. It also offers a genuinely useful free tier and SOC 2 certification for teams that need a compliance answer. The trade-off is scale of integrations: at roughly 200 native connectors, Relay.app covers far less ground than giants like Zapier, so teams with a long tail of niche or legacy tools may need to supplement with webhooks or custom API calls. Overall, Relay.app suits teams that want approachable, supervised AI automation rather than the broadest possible integration catalog or the deepest autonomous-agent capability.
