Relay

Relay.app is a no-code workflow automation platform built around AI agents, triggers, and multi-step workflows. It’s aimed at business teams and operations-focused users who want to automate processes across many tools, including custom internal systems, without writing code or heavily involving IT.

The platform runs in the browser and provides templates, integrations, and AI agent solutions (for example, for marketing workflows). You can start from predefined templates or build workflows that react to external events via webhooks, call external APIs, and include human-in-the-loop steps. According to their security page, Relay.app is designed to be adopted without deep technical setup, but the team can work directly with your IT and security teams if you have stricter requirements.

Relay.app appears well-suited for organizations that need reliable, API-level automation rather than just simple chatbots. Webhook triggers let you start workflows instantly from virtually any app or internal service, while custom HTTP requests make it possible to push or pull data from systems that don’t have native integrations. The ability to pause a workflow and wait for an incoming webhook, combined with human-in-the-loop steps, supports more complex, stateful processes where external systems or people need to weigh in.

From a security standpoint, Relay.app is SOC 2 Type II compliant, with a report available on request, which will matter if you’re in a regulated or enterprise environment. However, the publicly visible content doesn’t specify which AI models are used, how data is handled beyond SOC 2 controls, or the finer details of data retention and training, so you’ll likely need to review their documentation or contact them for a full privacy and architecture picture. Pricing details aren’t exposed in the provided content, only that there are multiple plans and a way to "start for free."

Relay.app is not an open-source or self-hosted framework, so if you require full on-prem control or deep model-level customization, it may not be the right fit. It’s also more of a general-purpose workflow and API automation tool than a personal assistant or home automation system, so teams looking for consumer smart home use cases will likely want alternatives.
