Comparisons · 12 pages

AI build decisions,
compared.

Each of these takes a position. Where our commercial interest points one way and the honest answer points the other, we have gone with the honest answer — those are the ones worth reading.

Introduction transcript. Client: Build our own, or buy something ready-made? Qubi: Two good options. Let’s put them on the table. Qubi: We compare the cost, the control, and what your team needs. Client: Even if buying means less work for you? Qubi: Of course. A good answer should help you choose. Qubi: Let’s find the trade-off that fits.

At a glance

How to read a comparison here.

01 Who wrote it
We build custom AI systems, so the pages about building custom AI systems deserve suspicion. The test is whether we argued the other side properly.
02 The standard
Each page leads with the case against the option we sell. A comparison that never concedes anything is not a comparison.
03 What decides it
Where a decision depends on your circumstances, the page names the variable that decides it: your cloud commitment, whether data may leave your perimeter, traffic volume, continuous or bounded work.
04 Figures and dates
Figures are indicative European ranges as of 2026, unsourced and labelled as such. Technology comparisons carry a review date, because a table written six months ago will mislead.
HOW TO READ THESE

Argued from both sides.

Most vendor comparisons are written by whoever benefits from one particular answer. So are these — we build custom AI systems, which means the pages about building custom AI systems deserve your suspicion. The useful test is whether we argued the other side properly.

That is the standard we hold them to. Each one leads with the case against the option we sell: the build-vs-buy page opens by telling you to buy, the agency-vs-in-house page opens with the conditions under which hiring is clearly better, and the no-code page opens by recommending you start on Zapier and stay there if it works. A comparison that never concedes anything is not a comparison.

Where a decision genuinely depends on your circumstances, we say so and name the variable that actually decides it — which cloud you are already committed to, whether data may leave your perimeter, traffic volume, whether the work is continuous or bounded. A page that resolves every trade-off in the same direction is telling you about its author rather than about the decision.

Figures are indicative European ranges as of 2026, unsourced and labelled as such. The technology comparisons carry a review date, because the major model providers ship frequently enough that a table written six months ago will mislead you. If something here has aged badly, it is a bug — tell us.

ARGUE THE OTHER SIDE

Argue the other side.

Pick a decision and read its side first. Each side is the page’s own opening argument, with the variable it turns on.

Choose a decision

Each side is drawn from its comparison page’s opening argument. Read the page for the whole case.

Build vs buy

Telling you to buy, first.

Build vs Buy AI opens by telling you to buy. It sets out when an off-the-shelf AI product is the right call, and when it structurally cannot be.

Build vs buy, the other side

Building is the answer when the variable points there.

We build custom AI systems, so treat this side with the suspicion the page asks for. These are the variables the comparisons name as deciding it.

Agency vs in-house

Hiring is clearly better under some conditions.

AI Agency vs In-House Team opens with the conditions under which hiring is clearly better, then sets out the real cost and time of hiring an AI team against engaging one.

No-code vs custom AI

Start on Zapier, and stay there if it works.

The no-code page opens by recommending you start on Zapier and stay there if it works. It sets out where Zapier, Make and n8n stop being enough, and what replaces them.
