The Verdict
Our pick: Zoho Flow. Zoho Flow wins based on its superior feature set and exceptional scalability within the Zoho ecosystem. It wins two of our five scoring categories and ties in two others, making it the stronger overall choice for businesses looking for a comprehensive and scalable automation solution.
However, Relay.app is the clear winner on Ease of Use and is the better choice for teams that need to inject manual approvals or human touchpoints into their automated workflows. If your primary need is collaborative automation with a modern interface, Relay.app is an excellent pick.

Feature Comparison
| Feature | Zoho Flow | Relay.app |
|---|---|---|
| Total Integrations | 1,000+ | 100+ |
| Visual Builder | Yes (Drag-and-drop) | Yes (Visual, step-by-step) |
| Conditional Logic | Yes (Decisions, custom functions) | Yes (Paths, branching logic) |
| Human-in-the-Loop | No (Requires custom development) | Yes (Core feature for approvals and data input) |
| AI Capabilities | Integrates with AI tools like ChatGPT and Zia. | Built-in AI actions (summarize, classify, extract) using GPT, Claude, & Gemini. |
| On-Premise Connectivity | Yes | No (Cloud-only) |
| Pre-built Templates | Yes (25,000+ in Flow Gallery) | Yes |
Zoho Flow wins the features category due to the sheer breadth of its capabilities. With over 1,000 integrations, it connects to a significantly wider range of business applications than Relay.app. This extensive connectivity, combined with advanced logic elements like custom functions and the ability to connect to on-premise applications, provides a more powerful and flexible automation toolkit.
Relay.app's feature set is more focused but highly effective at what it does. Its standout feature is the native "human-in-the-loop" functionality, which allows teams to easily insert manual approval or data entry steps into any workflow. This is a game-changer for processes that can't be fully automated, like payment approvals or content reviews. While its AI tools are more deeply embedded than Zoho Flow's, its smaller integration library gives Zoho the overall edge.
Ease of Use
Zoho Flow
- Traditional drag-and-drop interface is familiar but can get cluttered with complex flows.
- Deep customization options can present a steeper learning curve.
- Some users report documentation can be lacking for advanced use cases.
- Best for users familiar with the Zoho interface.
Relay.app
- Clean, modern, step-by-step builder is highly praised for its intuitiveness.
- Guided setup and live data previews simplify testing and building.
- Human-in-the-loop feature is simple to configure with a single toggle.
- Designed for non-technical users to build and deploy automations quickly.
Relay.app is the clear winner in ease of use. Its platform is designed from the ground up for simplicity and collaboration, earning praise for its intuitive, clean interface that allows non-technical users to build workflows in minutes. The process of adding human approval steps—a complex task in other systems—is effortless in Relay.app, making it exceptionally user-friendly for team-based processes.
Zoho Flow uses a more traditional drag-and-drop builder which is powerful but can become difficult to manage with highly complex, multi-step flows. While it's straightforward for simple connections, especially for those already accustomed to the Zoho ecosystem, its advanced features and custom functions require more technical expertise and the learning curve can be steeper.
Reliability & Ecosystem
| Category | Zoho Flow | Relay.app |
|---|---|---|
| Reliability | Comprehensive flow histories and audit trails for troubleshooting. Some users report connection instability. | Real-time monitoring of integrations. Strong early user feedback on reliability. |
| Support | Phone, email, online resources. Response times can be slow (48+ hours). | Email-only support, but praised as fast and helpful by users. |
| Ecosystem | Part of the Zoho suite of 50+ integrated business apps (CRM, Books, Desk, etc.). | Standalone platform focused on workflow automation. |
| Scalability | Extremely high for businesses invested in Zoho One; scales with your entire business operation. | Scales with usage tiers (steps/credits) and adding team members. |
Reliability & Support: Tie. Both platforms are considered reliable for their core functions. Zoho Flow provides detailed histories and audit logs for debugging, though some users have experienced connection issues. Relay.app receives strong praise for its stability from early adopters. While Zoho offers more support channels, users report that Relay.app's email-only support is often faster and more responsive, resulting in a tie for this category.
Ecosystem & Scalability: Zoho Flow wins. This is where Zoho Flow's advantage becomes undeniable. As part of the Zoho ecosystem, it integrates natively with over 50 other business applications, from CRM to finance and HR. For any company using other Zoho products, Flow is the default choice and offers nearly limitless scalability as the business grows and adopts more tools from the suite. Relay.app, as a standalone product, cannot compete on this front; it integrates with other ecosystems but does not have one of its own.
