Zapier vs. Make vs. custom code: an honest comparison

This post sits inside a bigger guide — Your tools, finally working together: the integration playbook. The playbook says: wire your tools together, integration first. This post answers the next question: with what?

Nobody's paying me to write this. I build custom integrations for a living, and I'm going to tell you when you shouldn't hire someone like me.

Zapier: the easy button

What it is: the best-known automation tool. Point-and-click connections between thousands of apps. If both your apps are popular, the connector probably already exists.

Where it wins: speed and simplicity. A non-technical person can wire "new form submission → create CRM record → send Slack message" in an afternoon. The app library is the biggest in the business, and the docs are good.

Where it loses: the pricing. Zapier charges per "task," and every step of every automation counts. A five-step flow that runs 1,000 times a month isn't 1,000 tasks — it's 5,000. The bill grows with your success, which means the better your automation works, the more you pay for it.

Say what vendors won't: Zapier's pricing punishes your growth. That's not an accident — it's the business model. At low volume it's cheap and wonderful. At high volume you're paying a success tax every month, forever.

Pick Zapier when: your flows are simple, your volume is low (a few hundred runs a month), and you want somebody on your team to own it without calling a developer.

Make: the power tool

What it is: Zapier's main rival. Visual, drag-and-drop, but built for more complex logic — branching, loops, data transformation, the stuff that makes Zapier users hit a wall.

Where it wins: price per operation and flexibility. Make's "operations" are generally cheaper than Zapier's tasks, and one scenario can do work that would take three Zaps. If your flow has real logic in it — "if the deal is over $10k, do this, otherwise do that" — Make handles it gracefully.

Where it loses: the learning curve. It's visual, but it's not simple. Error handling, data mapping, and debugging take real practice. The template library is thinner, so you'll build more from scratch. And the operations math is genuinely confusing — figuring out what a scenario will actually cost takes a spreadsheet and some patience.

Say what vendors won't: Make is cheaper until you factor in the hours your team spends learning it and debugging it at 9pm. The tool is priced well; the expertise isn't free.

Pick Make when: your flows have real branching logic, your volume is medium to high, and someone on the team is willing to learn the tool properly.

Custom code: the owned asset

What it is: software written for your specific job — a small service that moves data between your apps exactly the way you need, running on your infrastructure.

Where it wins: at scale, the math flips hard. No per-task fees, no per-operation meter. Whether it runs 100 times a month or 100,000, the cost is the same: the server it runs on, which is usually pocket change. It also does things the platforms can't — weird APIs, custom logic, tight control over data, no dependence on a vendor's roadmap.

Where it loses: the upfront cost and the maintenance. Somebody has to write it, and somebody has to keep it running when APIs change. That's real money up front and a real (small) ongoing responsibility. For a simple low-volume flow, it's overkill — like hiring an architect to hang a shelf.

Say what vendors won't — including about people like me: most small businesses don't need custom code yet. If your volume is low and the flow is standard, Zapier or Make will get you 90% of the value at 10% of the cost. Any developer who tells you otherwise is selling, not advising. We'll tell you not to build it when the math doesn't work.

Pick custom code when: your volume is high enough that per-run pricing hurts, the logic is unusual enough that the platforms fight you, or you want to own the thing outright with no monthly meter.

How the cost curves bend

Here's the shape of it, as an illustration. Say a five-step flow runs 2,000 times a month:

• Zapier: 10,000 tasks/month lands you on a paid tier — roughly tens of dollars a month. Fine.
• Make: the same work costs meaningfully less in operations — often half or better. Fine.
• Custom code: a few thousand dollars to build, then nearly nothing to run. Overkill at this volume.

Now run it 50,000 times a month:

• Zapier: 250,000 tasks. You're now paying hundreds a month, every month, forever. Not fine.
• Make: still cheaper than Zapier, but the bill is real now.
• Custom code: still nearly nothing to run. The upfront cost paid for itself months ago.

The crossover point is different for every business, but the pattern is universal: platforms are cheap to start and expensive to scale; code is expensive to start and cheap to scale. Know which side of the curve you're on.

What we'd actually recommend

For most of the businesses reading this — 8 to 25 people, standard apps, standard flows — the honest answer is: start with Zapier or Make. Get the win. Feel the hours come back. Then, when the monthly bill starts to sting or the platform can't do what you need, that's the moment custom code earns its keep.

One more thing the vendors won't say: switching later is normal, and it's fine. Start on the platform, and when the bill stings, migrate the highest-volume flow to code first and leave the rest where it is. You don't have to pick one winner for everything — most businesses we work with end up with a mix: platforms for the odd low-volume flows, owned code for the heavy ones. Start cheap, graduate when the math says so.

And when that moment comes: fixed price, live in 2–4 weeks, you own everything outright. No meter, no lock-in, plain English the whole way. That's how we build.
