n8n

Bottom Line
Last reviewed: August 2026
n8n and Relay.app both compete in Automation, overlapping most directly on automation. n8n carries the higher rating (4.7 vs 4.5), but a gap that size rarely overrides a real workflow fit on its own.
Choose n8n if…
Best for teams that want automation they can self-host and fully control, and its edge is free and self-hostable, with the same visual workflow builder as the paid competitors. The best choice when you want Zapier's flexibility without the recurring cost.
Choose Relay.app if…
Best for teams whose workflows genuinely need a human approval or review step, not full automated end-to-end flows, and its edge is builds structured human decision points directly into the automation instead of treating every step as fire-and-forget. The right tool when human judgment matters mid-workflow, it's a newer, smaller product than Make for complex flows.
