Relay.app

What is Relay.app?

Relay.app is a workflow automation platform that combines classic app integrations with AI steps and optional human-in-the-loop approvals. Unlike many competitors, all integrations are included in every plan. The free tier provides a monthly step and credit allowance; the Professional plan increases both.

As with other platforms, automations are built from a trigger and a series of actions that talk to services like Gmail, Slack, HubSpot, or Notion through app integrations. Two things set Relay.app apart: first, you can insert AI steps that, for example, summarize text, generate content, or classify data — useful for not just moving data around but actually "understanding" it. Second, it has a well-thought-out human-in-the-loop feature: at critical points a workflow can pause and wait for a human approval or input before continuing. That makes the platform particularly interesting for processes where full automation would be too risky.

Relay.app: Strengths and weaknesses

The biggest strengths are its transparent pricing and human-in-the-loop logic. The fact that all integrations are included in every plan avoids the common competitor annoyance where "premium apps" force you onto a more expensive tier. The approval steps fill a genuine gap between full automation and manual control — ideal, for example, for approval workflows or AI-generated content that should be reviewed before sending. The interface is regarded as modern and clean.

Relay.app is weaker on the sheer breadth and maturity of its integration ecosystem: as a younger platform, it doesn't (yet) match the thousands of connections offered by established providers. Anyone who needs a very specific niche app is more likely to find it on Zapier or Make. For complex, branching logic and self-hosting, specialized platforms like n8n are also more flexible. For common business processes with AI and approval steps, however, Relay.app is a compelling and fair option.

Pricing and plans

Relay.app is a freemium tool. The free tier provides a monthly allowance of workflow steps and AI credits and is well-suited to testing as well as smaller automations. The paid Professional plan starts at around $19 per month and significantly increases both the step and the credit allowance; above that sit Team and Enterprise tiers with more capacity and collaboration. Importantly, all integrations are included in every plan — differences come mainly from volume and team features. Current pricing is always listed on the official Relay.app website.

Who is Relay.app for?

Relay.app is especially well-suited to teams and individuals who want to automate common business processes while building in AI steps and targeted human control — such as approval workflows, AI-assisted reply drafts, or onboarding processes with sign-offs. Its fair pricing structure also makes it attractive to price-sensitive users. Those who need the broadest possible integration ecosystem or self-hosting, by contrast, should additionally check out Zapier, Make, or n8n.
