The Tool Money Lab Verdict

Our editorial call on Relay.app vs Zapier

After spending real time with both Relay.app and Zapier, our editorial view is that these tools solve overlapping problems in very different ways. Relay.app is built for teams that want ai automation with approval steps., while Zapier is aimed at non-technical teams automating saas workflows.. Neither is objectively "better" — the right answer depends on the work you actually do, not on which product has the flashier launch video.

Zapier takes the edge on our internal scorecard (90/100 vs 84/100), but that headline number hides the nuance. Relay.app tends to win on human approvals built in, while Zapier pulls ahead on largest app catalogue. If your workflow leans heavily into either of those, the "winner" for you changes.

Our recommendation is to pick the tool that matches the way you already work, rather than the one with the broader marketing footprint. The gap between them is not large enough to justify fighting your own habits — but it is large enough that the wrong choice will cost you time every day for months.
