Almost every automation conversation we have starts here, so it is worth writing down properly.
Breadth of integrations and a gentler learning curve. If your stack is mainstream and your workflows are linear — this happens, then that happens — Zapier will get you live faster and your team will be able to read what you built without training.
Complexity and cost at volume. Make's visual scenario builder handles branching, iteration and error handling in a way Zapier makes awkward, and once you are running tens of thousands of operations a month the pricing difference stops being academic.
Under ten steps, mainstream apps, low volume: Zapier. Branching logic, data transformation, high volume, or anything you expect to keep extending: Make.com. If you are genuinely torn, build the first workflow in Make — it is easier to simplify later than to outgrow a tool and migrate.
If you find yourself fighting the tool for more than a day, that is the signal to write actual code. No-code platforms are excellent up to a ceiling, and past that ceiling a small custom script is cheaper to run and easier to reason about.
