Relay.app Review 2026: Is It Worth It?

Relay.app Review Summary

Relay.app is shutting down. Subscriptions were cancelled 16 July 2026, free access ends 15 August 2026, and the service closes on 14 September 2026 (see what to do). This review is retained as a historical record.

Relay.app was an automation platform built around the concept of human-in-the-loop workflows — automations that pause at designated steps to request human approval, input, or review before proceeding. As of March 2026, the platform targets teams that need automation with human oversight, such as content approval, expense authorization, and hiring workflows. This review evaluates Relay.app on its unique capabilities, integration depth, pricing, and overall value.

Strengths

1. Native Human-in-the-Loop

Relay.app's core differentiator is built-in human approval steps. Workflows can pause at any point and send an approval request to a designated person via email, Slack, or the Relay.app dashboard. The approver can approve, reject, or provide input that gets passed to subsequent workflow steps. This is not a workaround — it is the platform's primary design pattern.

2. Per-Run Pricing

Runs are counted per workflow execution, not per step. A 6-step workflow with an approval pause counts as 1 run. This makes Relay.app substantially cheaper per equivalent workload than Zapier's per-action-step task billing. The Pro plan at $9.99/month for 2,500 runs offers strong value.

3. Clean Interface

The workflow builder is clean and intuitive. Approval steps are visually distinct, making it easy to see where human interaction points occur in a workflow. The approval request interface (what the approver sees) is well-designed with clear context about what is being approved.

4. Practical Free Tier

The free plan with 100 runs per month is sufficient for testing and low-volume approval workflows. Many small teams can operate within this limit indefinitely for their most critical approval processes.

Weaknesses

1. Limited Integration Ecosystem

Relay.app supports approximately 100 integrations as of March 2026. This is a fraction of Zapier's 9,000+ or Make's 2,000+. Organizations using niche SaaS tools will frequently encounter missing integrations. Webhook and HTTP request steps provide workarounds for technical users.

2. Narrow Use Case

If workflows do not require human approval steps, Relay.app provides no advantage over Zapier or Make. The platform's value proposition is tied entirely to the human-in-the-loop capability. Teams with fully automated workflows should choose a broader platform.

3. No Self-Hosted Option

Relay.app is cloud-only. Organizations with data residency requirements or preferences for self-hosted automation have no option.

4. Limited Advanced Features

The platform lacks advanced features found in more mature tools: no sub-workflows, limited error handling configuration, no native AI/LLM steps, and limited data transformation capabilities.

Verdict: 6.8/10

Relay.app is a purpose-built tool for a specific need: automations that require human judgment at critical steps. For that use case, it provides a cleaner, more cost-effective solution than building approval workarounds on Zapier or Make. The per-run pricing model and built-in approval interface are genuine differentiators. However, the limited integration ecosystem and narrow focus mean most teams will need a secondary automation platform for workflows that do not require human approval.

Editor's Note: We deployed Relay.app Pro ($9.99/month) for a marketing team that needed manager approval for social media posts, blog publications, and ad spend above $500. The team runs 12 approval workflows processing approximately 350 runs per month. The approval experience — receiving a Slack notification with the content to review and approving with one click — is noticeably smoother than the Zapier-based approval process the team previously used (which required checking email, clicking a link, and filling out a form). The main limitation: the team also uses 8 fully automated workflows (no approval needed) that run on Zapier separately, because Relay.app's integration coverage did not support 3 of the required tools. For approval-heavy teams, it is worth the $9.99/month as a supplementary tool alongside a broader platform.
