Zapier vs Nrth Star: who builds the automation, and who keeps it alive

Zapier is the reason most people know automation is possible at all. It has been around since 2011, it connects to several thousand apps, and if you have ever moved a form submission into a spreadsheet without writing code, you have probably done it there.

So this is a real comparison, not a category mix-up. Zapier and Nrth Star are trying to do the same thing for you. They disagree about how much of it you should have to do yourself.

The short version

Zapier gives you the tools. You decide what to build, you build it step by step, you connect the accounts, you test it, and from then on it is yours to keep alive. It is a very good workshop, and the work is still work.

Nrth Star does the job. It works out what is worth automating, writes the automation as a plan you read and approve, proves it against your last 30 days before it touches anything, and then maintains it. There is no editor, because there is nothing for you to assemble.

The difference is not features. It is where the work sits. Zapier assumes you know what to build and are willing to build it. Nrth Star assumes you do not and are not.

What Zapier is better at, plainly

Three things, and none of them are close.

Coverage. Zapier connects to several thousand apps. Nrth Star connects to 900+ natively and to anything else with a public API, which is most things, but the diagnostics are thinner on an app it does not know first-hand. If your agency runs on something genuinely obscure, check before you switch.

Control. In Zapier you can see every step and change any of them. If you want a filter that fires only on Tuesdays for clients in one pipeline stage whose name starts with a letter before M, you can build that in ten minutes and nobody has to agree with you. Nrth Star works from an approved plan, which is slower on purpose.

One-off jobs. Moving a form into a spreadsheet is two steps and five minutes in Zapier. That is not a problem worth an audit, a plan and a shadow run, and pretending otherwise would be silly.

If those matter more to you than what follows, use Zapier. It is a good product and this is not a trick question.

The three differences that actually matter

1. Zapier starts on a blank page

Open Zapier and it asks what you want to build. That is only a useful question if you already know the answer, and most agency owners do not. They know the month felt busy. They cannot say whether the time went on onboarding, on chasing quotes, or on rebuilding the same report.

This is the failure nobody logs. The automation you build is the one you happened to think of, not the one costing you the most, and there is no way to tell the difference from inside an editor.

Nrth Star starts with the audit: it asks how your agency runs, surveys the rest of the team anonymously so the picture covers the hours a founder never sees, and returns a ranked list with a number against each item. You pick from that. Nothing is connected, and no card is needed.

2. Somebody has to be the person who builds it

A Zap is assembled. Choose a trigger, add an action, map this field to that field, add a filter, add a formatter step because the date is in the wrong format, add a delay, test, discover the CRM returns the company as an ID rather than a name, add a lookup step.

None of that is hard. All of it is fiddly, and it lands on one person, usually the founder or the one operations hire who is good with software. Six months later that person is the only one who understands forty Zaps and cannot take a fortnight off.

Nrth Star has no editor. You describe the job in plain English and it writes back what the process is now, what should happen instead, and what it still needs to know. You approve that or correct it in ordinary words. There are no nodes, no canvas and no field mapping, because there is nothing for you to assemble.

3. Somebody has to keep it alive

This is the one that decides it, and it is invisible when you are choosing.

Third-party systems change. A field is renamed, an API version is retired, a permission is tightened. In Zapier the run fails, the Zap is turned off after enough failures, and you get an email. What the email cannot tell you is what to do about it, so somebody opens the editor and works out which of the seven steps changed underneath them.

Nrth Star watches for those changes. When one needs a decision you are told what stopped and what will fix it, the automation is paused rather than left half-working, and the fix waits for your approval. It never repairs itself quietly, because an automation that fixed itself wrong does not fail. It succeeds at doing the wrong thing to real clients.

Before it goes live

Zapier lets you test a step against a sample record. That tells you the step runs. It does not tell you what the whole automation would do to your actual client list, which is the question you have at 5pm on the day you turn something on.

Nrth Star does a shadow run. The automation is replayed across your last 30 days with everything switched off. No emails are sent and nothing changes. You see what it would have done, against real clients and real dates, and you find out there that it would have chased a client who had already paid, before it does.

Then arming it is its own deliberate action, and one press turns it off again.

Tasks versus automations

The pricing models are different in a way that matters more as you grow.

Zapier charges by tasks. Every step of every run counts, so a five-step automation that runs a thousand times a month draws down five thousand tasks. The bill therefore scales with how busy your agency is, which is the same thing as saying it goes up in your best months. Working out what next month costs means estimating volume and multiplying by step count.

Nrth Star charges by the number of automations you are running, whatever they run. Not tasks, not credits, not tokens, not seats. Starter is $49 a month for 2 active automations, and the AI writing is included with nothing to buy on top. You know the bill before you get it.

One automation means one thing that starts it. “Follow up on unanswered proposals” is one. “Welcome a new client” is another. If you describe three separate things that should happen, that is three, and they are built separately on purpose so one breaking never takes the others down with it.

Built for everyone, or built for agencies

Zapier is horizontal. It serves a dental practice, a logistics company and a marketing agency out of the same editor, which is why it connects to so much and why it cannot have an opinion about any of them.

Nrth Star only works with marketing agencies. That is a smaller market and a deliberate one: it means the audit already knows what a retainer is, what a proposal cycle looks like, and that reporting week is the worst week of the month. Advice that is right for everybody is usually not specific enough to act on.

So which one

Use Zapier if you know what you want to build, you want to see and control every step, you need an app we do not cover, or the job is small enough that building it yourself is genuinely faster. Plenty of agencies are in exactly that position.

Use Nrth Star if you know you are losing time and cannot say where, if nobody at your agency wants to become the automation person, or if you already have a pile of Zaps that somebody has to babysit and you would rather that stopped.

Plenty of agencies will keep both, and they do not conflict. Leave the two-step connections where they are. Hand over the things that break, the things that matter, and the things nobody has got round to building.

The audit is free permanently, connects to no accounts and needs no card. If you are not sure whether this is worth changing, it will tell you what your agency is actually losing time on, and that is a useful answer whichever tool you end up using.
