Relay.app is an AI-powered, visual workflow automation platform that helps teams build AI agents, connect business apps, and run human-in-the-loop processes.
Relay.app is an AI-powered, visual workflow automation platform designed to help teams and developers build automated pipelines without writing code. By offering an intuitive drag-and-drop canvas, it enables users to connect their business tools, design complex paths, and automate workflows in minutes. The tool is designed to make operational automation accessible to anyone, regardless of technical background.
At its core, Relay.app integrates advanced large language models (such as GPT-4, Claude, and Gemini) and custom logic structures directly into standard workflow nodes. It also includes unique "Human-in-the-Loop" checkpoints, allowing teams to require manual approval or feedback at key stages (like double-checking a drafted email before it goes live).

✔ Seamless visual drag-and-drop builder makes creating multi-app automations highly accessible.
✔ Robust Human-in-the-Loop features ensure manual review for high-impact actions like invoicing or approvals.
✔ Multi-model AI agent steps (like translation or classification) are natively supported within standard pipelines.
✔ Free plan includes a generous allotment of 200 automation steps and 500 AI credits monthly.
✔ Does not lock advanced features or integrations behind expensive enterprise plan tiers.
✔ Unlimited free test runs make it cheap and safe to debug and test complex automated sequences.
✔ Easy-to-configure team collaboration features on the Team plan with support for up to 10 users.
✖ The pre-built direct application integration list is smaller than legacy platforms like Zapier.
✖ Running high-volume AI processes can deplete your monthly AI credit allotment quickly.
✖ Advanced conditional branching or complex nested loops require some trial and error to configure.
✖ Free plan is limited to a single user seat and lacks team workspace permissions.
✖ Heavily relies on credit-based plans, which can lead to overage costs if usage spikes unexpectedly.
✖ Lacks advanced enterprise-grade security features like SAML SSO on the lower-priced plans.

Relay.app stands out by offering native AI steps (such as summarization or data extraction) and robust "Human-in-the-Loop" controls that pause workflows for manual review. Traditional tools like Zapier have a larger catalog of app integrations but lack built-in manual verification steps.
This feature allows you to insert approval or input steps directly into a workflow. For example, a workflow can automatically draft an email, pause for you to review or edit the text, and send it only after you click approve.
A step is any standard action performed in a workflow, such as moving data from a trigger to another app. An AI credit is specifically consumed when running an action powered by an AI model (like GPT or Claude) to parse, classify, or write copy.
Yes, Relay.app includes free test runs on all plans that refresh weekly. These runs allow you to dry-run and debug your integrations without consuming your monthly live automation limits.
No. Unlike some competitors that place specific premium integrations behind paywalls, Relay.app provides all integrations on all plans, including the Free tier. Plan upgrades are solely based on usage capacity (steps and credits) and collaboration seats.
