The short version

  • Only Logto has a free tier, so it costs nothing to try first.
  • Each has a real cost: Logto advanced features like RBAC, organizations, MFA, and enterprise SSO are billed as separate paid add-ons rather than included in Pro.; Zencity social listening is structurally biased toward residents who post, so a city using the listening product without the survey product will consistently mistake volume for consensus.
  • They diverge on capability: Logto covers Prebuilt sign-in UI, Zencity covers Organic social listening.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

Logto

  • Advanced features like RBAC, organizations, MFA, and enterprise SSO are billed as separate paid add-ons rather than included in Pro.
  • Enterprise pricing is not published and requires contacting sales.
  • Token-based billing can make cost forecasting harder than flat per-MAU pricing for high-traffic apps.

Zencity

  • Social listening is structurally biased toward residents who post, so a city using the listening product without the survey product will consistently mistake volume for consensus.
  • Government analysis of residents' public speech, particularly by police departments, has drawn civil liberties criticism and records request scrutiny in United States cities, and agencies need a public answer ready before signing.
  • Sentiment classification of local slang, sarcasm and non English posts is imperfect, and a misclassified theme presented in a leadership briefing can be acted on before anyone checks the underlying posts.
  • Survey sample sizes at neighbourhood level are often small, so the district level breakdowns that councils most want are the least reliable numbers in the report.
  • It reports on opinion without connecting to service delivery systems, so acting on a finding remains a separate manual process in whatever operational software the agency runs.

Answered from the vendors’ own pages

Logto: What does Logto cost?

Logto offers a Free plan at $0/month, a Pro plan starting at $24/month with 50K free tokens included, and a custom-priced Enterprise plan. Extra add-ons like RBAC or MFA are billed separately on Pro.

Source
Zencity: Is this surveillance of residents?

It analyses publicly posted content and aggregated survey responses rather than private accounts, but the distinction has been contested publicly, especially for police use. Prepare an explanation before procurement.

Logto: Is there a free plan, and what are its limits?

Yes. The Free plan supports up to 50,000 monthly active users, 3 total applications, 1 machine-to-machine app, 3 social connectors, 1 webhook, and 3-day audit log retention.

Source
Zencity: Why pair listening with surveys?

Because the people who post are not representative of the people who live there. The gap between the two datasets is often the most useful output.

Logto: How is usage metered?

Logto uses token-based billing: only access tokens issued for authentication and authorization activity are counted, rather than charging purely per MAU.

Source
Zencity: What did Zencity acquire?

Elucd, in 2021, which brought community trust survey methodology used with police departments.

Zencity: Can residents find out what our city bought?

Yes. These are public contracts and several have been obtained and published through records requests.
