Relay.app

What Relay.app Actually Does

Relay.app is a workflow automation tool built around one core idea: not every step in a business process should be fully automated. Its standout feature is the ability to insert a human approval or input step mid-workflow — so automation runs up to a point, pauses for a person to act, then continues.

This is a real gap that tools like Zapier don't address well. If you're automating client onboarding and need a team member to review a proposal before it goes out, Relay handles that natively.

Where It Works Well

Relay fits teams running process-heavy operations where some steps carry enough risk or nuance that full automation isn't appropriate. Think:

• Sales outreach sequences with a human review before sending
• Content publishing workflows requiring editorial sign-off
• Client onboarding with conditional logic and manager checkpoints

The interface is clean and the workflow builder is approachable without being dumbed down. Setting up branching logic and assigning human tasks to specific team members is straightforward.

Where It Falls Short

The integration library is the biggest limitation. Relay supports the major platforms — Gmail, Slack, HubSpot, Airtable, Notion — but if your stack goes beyond that, you'll run into dead ends. Zapier's 5,000+ app catalog dwarfs what Relay currently offers.

The human-in-the-loop model is also a double-edged sword. If your team doesn't respond to approval requests promptly, workflows stall. You're essentially building bottlenecks into your automation, which defeats the purpose if team discipline is inconsistent.

At a ROI score of 49/100, Relay sits in uncertain territory. The concept is sound, but the time savings are inherently capped by how often humans need to intervene.

Pricing Reality

Starting at $9/mo, the entry point is low enough to test. But teams with meaningful workflow volume will likely need higher tiers. Evaluate based on your monthly run count and whether you need multiple collaborators on the same workflows.

Bottom Line

Relay.app is worth trying if you've been frustrated by fully-automated tools making costly mistakes without any human checkpoint. It's not the right pick if you need broad integrations or want hands-off automation at scale.
