The short version

  • Each has a real cost: SurveyCTO pricing is by submission volume, forms and storage rather than by users, so a small team running continuous high-volume collection can pay more than a 200-person survey team that runs for six weeks; Umami there is no cohort analysis, retention curve, session replay or multi-touch attribution, so a marketing team that needs to justify channel spend will still buy a second tool and Umami becomes a supplementary dashboard.
  • They diverge on capability: SurveyCTO covers Offline collection, Umami covers Cookie-free tracking.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

SurveyCTO

  • A household survey with 200 enumerators across a country where paying per seat would cost more than the fieldworknot Umami
  • An impact evaluation that needs audio auditing and timing metadata to prove interviews were conducted as reportednot Umami
  • A panel study revisiting the same households annually and needing offline case assignment to find them againnot Umami
  • A statistics unit that must keep data inside a specific region and produce a SOC 2 report for its fundernot Umami

Umami

  • A developer who wants traffic numbers on a personal or client site without adding a consent bannernot SurveyCTO
  • An organisation whose legal or procurement team has ruled out sending visitor data to a US advertising companynot SurveyCTO
  • A high-traffic site where hosted analytics priced by pageview band has become expensive and self-hosting removes the ceiling entirelynot SurveyCTO
  • A team that wants analytics data in a database they already control so they can query and join it themselvesnot SurveyCTO

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

SurveyCTO

  • Pricing is by submission volume, forms and storage rather than by users, so a small team running continuous high-volume collection can pay more than a 200-person survey team that runs for six weeks
  • Forms are authored in XLSForm spreadsheet syntax, which is precise and versionable but has a real learning curve, and organisations without someone comfortable in it stall at form design
  • Overage is charged at 100 US dollars per 1,000 extra submissions, which is easy to trigger on the Basic tier at 5,000 a month and produces surprise invoices during an active field round
  • Server region selection only appears on the Pro tier and a custom GDPR data processing agreement only on Advanced, so European data protection requirements push the price to at least 315 and often 630 dollars a month regardless of volume
  • It is built for structured research fieldwork, not for business process forms, so it has no dispatch, no invoicing and no formatted document output, and a field service business would be buying the wrong tool

Umami

  • There is no cohort analysis, retention curve, session replay or multi-touch attribution, so a marketing team that needs to justify channel spend will still buy a second tool and Umami becomes a supplementary dashboard.
  • Self-hosting is only free in licence terms; you own the database, the upgrades, the backups and the query performance at scale, and a busy site's events table grows quickly enough to need real attention.
  • Because it stores no persistent identifier, it cannot follow a user across devices or sessions in any meaningful way, which makes returning-visitor and lifetime-value questions unanswerable by design rather than by omission.
  • Cloud overage is billed per event beyond the plan allowance, so a traffic spike or a badly instrumented custom event can produce a bill materially above the $20 or $200 headline before anyone notices.
  • It is maintained by a small team, so the pace of new capability is modest and enterprise expectations such as SSO, granular role permissions and formal support agreements are limited compared with commercial analytics vendors.

Answered from the vendors’ own pages

SurveyCTO: Do I pay per enumerator?

No. Users and devices are unlimited on every paid tier. You pay for monthly submissions, forms and storage.

Umami: Is Umami really free?

Self-hosted, yes; it is MIT licensed with no event cap. You pay for the server and database. Umami Cloud has a free tier at 100,000 events a month and paid tiers from $20.

SurveyCTO: Is there a free version?

Yes, a permanent community subscription with 10 forms, 200 monthly submissions and 200 MB of storage, intended for testing and training rather than production.

Umami: Do I need a cookie consent banner?

For Umami analytics specifically, generally no, because it sets no cookies and stores no personal data. Other tags on your site may still require one.

SurveyCTO: What happens if I exceed my submissions?

Extra credits are 100 US dollars per 1,000, with discounts of 20 per cent or more at volume. Plan the tier around your peak field month, not your average.

Umami: Can it replace Google Analytics?

For traffic, referrers and event counts, yes. For attribution modelling, audiences and advertising integration, no.

SurveyCTO: Can I choose where the data is stored?

Only on Pro and above. If data residency matters, budget for at least the Pro tier.

Umami: What does it need to run?

A container and a PostgreSQL or MySQL database. Most people deploy it on infrastructure they already pay for.
