Mo does field-level form analytics too — and it is free for your first site. Below is an honest comparison, including the parts where Zuko is the better choice.
Zuko has been doing this for years and it shows. Session replay, hourly behaviour alerts, AI-written abandonment summaries and a dedicated Shopify checkout product are all things Mo does not have. They run in an ISO 27001 data centre and publish named enterprise customers — Capital One, Experian and Hiscox among them.
If you are buying through a procurement process that asks for references and certifications, that is a real advantage and we are not going to pretend otherwise.
Price, and the ability to start without talking to anyone. Zuko's entry plan is £50 a month for 5,000 sessions and there is no permanently free tier at all. Mo gives you 1,000 sessions a month on one site free, forever, and £29 a month buys up to 10,000 sessions.
Every core report is on the free plan — funnels, field drop-off, abandonment. You outgrow Mo on volume; only alerts and the journey evidence report are kept for Business and Build your own.
Zuko figures taken from their published pricing and feature pages, checked on 9 August 2026. Monthly billing; they also offer roughly 20% off for annual.

| AI-written summaries | No | Yes |
| Shopify checkout product | No | Yes, a dedicated product |
| Page quality checks | Yes — unnamed and duplicated links, from the page structure | Form Health Check, AI-powered |
| Consent | Reads and writes nothing until consent is granted | States GDPR compliance and no PII transmitted |

| Security certification | None published | ISO 27001 data centre |
A comparison where the author wins every row is marketing, not information. These are the cases where we would tell you to go elsewhere.
Session replay answers "what on earth were they doing" in a way no aggregate can. Mo has no equivalent and no plans to pretend otherwise.
Named enterprise customers and an ISO 27001 data centre clear hurdles that a new product simply cannot. If your security review has a checklist, Zuko will pass more of it.
Hourly behaviour alerts and AI-written summaries push findings at you. Mo emails a daily drop-off alert on Business and Build your own; otherwise it expects you to open the dashboard.
Zuko sells a product built specifically for that. Mo tracks it as it would any other multi-step form, with nothing Shopify-aware.
The free plan is free permanently, not for fourteen days, and it takes one script tag. If Mo turns out not to be enough, you will have lost an afternoon and learned which field is costing you the form.
