The short version

  • Only StackBlitz has a free tier, so it costs nothing to try first.
  • Each has a real cost: StackBlitz specific Teams and Enterprise pricing figures are not published; visitors must request a quote or infer from the pricing calculator.; Sumsub the published per-verification rate is undercut by a monthly minimum of 149 or 299 dollars, so low volume businesses pay a much higher effective rate than the headline suggests.
  • They diverge on capability: StackBlitz covers WebContainers, Sumsub covers Document verification.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

StackBlitz

  • Specific Teams and Enterprise pricing figures are not published; visitors must request a quote or infer from the pricing calculator.
  • Browser-based execution via WebContainers has limits on which native/binary dependencies can run compared to a real server-backed environment.
  • Heavy or resource-intensive workloads may be constrained by the end user's own browser and machine resources.

Sumsub

  • The published per-verification rate is undercut by a monthly minimum of 149 or 299 dollars, so low volume businesses pay a much higher effective rate than the headline suggests.
  • You are billed per verification attempt in most configurations, meaning applicant drop-off and resubmissions cost money without producing a customer.
  • Pass rates and document support vary noticeably by country, and a market that works well in Europe can produce materially worse rejection rates in parts of Africa and South East Asia.
  • The AML screening tier bundles list coverage that large institutions would normally buy separately and tune, giving less control over match thresholds than a dedicated screening vendor.
  • The company originated in Russia before restructuring to a UK entity, and some financial institutions still raise that history in vendor risk review, which can slow or block procurement at conservative banks.

Answered from the vendors’ own pages

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

Yes, the free Personal plan includes unlimited public StackBlitz projects, collections, and GitHub repositories, and lets anyone view and edit projects without needing a GitHub account.

Source
Sumsub: What does a verification actually cost?

1.35 USD on Basic and 1.85 USD on Compliance, but with 149 and 299 USD monthly minimums respectively. Below roughly 110 or 160 checks a month you are paying the minimum, not the rate.

StackBlitz: What does the Teams plan add?

Teams lets GitHub organizations add free or paid members; paid members get access to private collections and repositories, with permissions mirrored from GitHub-owned repos.

Source
Sumsub: Do failed verifications get charged?

Attempts are generally billable, so a poor onboarding funnel raises your bill. Confirm the exact resubmission policy in your contract.

StackBlitz: Is there an Enterprise option?

Yes, custom Enterprise plans are available and require contacting StackBlitz directly.

Source
Sumsub: Does it cover business verification?

Yes, KYB with company registry lookups and beneficial owner resolution is part of the platform rather than a separate product.
