I can confirm, we use Temporal and used Tray.io for a bit. They're not operating at the same level at all, Tray/Zapier kind of drag and drop wire things together can be great to solve some quick pain points, but I would not build a product on top. Temporal has been great, it's also allowed us to significantly simplify our infra around workflows and made it a lot easier to understand what's going on, especially when things go wrong.
