  • 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.; Transmit Security pricing is not published, so it cannot be compared early against competitors that post per monthly active user rates, and the eventual quote often mixes per-user and per-transaction units.
  • They diverge on capability: StackBlitz covers WebContainers, Transmit Security covers Passwordless authentication.
  • 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.

Transmit Security

  • Pricing is not published, so it cannot be compared early against competitors that post per monthly active user rates, and the eventual quote often mixes per-user and per-transaction units.
  • Migrating a live consumer identity base is a high risk project, and credential migration constraints mean some users must re-register, which shows up as measurable churn.
  • The vendor is smaller than the identity incumbents, so the partner and systems integrator pool is thinner and staffing a large programme is harder.
  • Workforce identity is not the focus, so an organisation wanting one vendor for employees and customers will still run two platforms.
  • The fraud detection value depends on traffic volume feeding the models, so a smaller deployment gets less benefit from exactly the capability that justified choosing it over a plain identity provider.

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
Transmit Security: Do we have to replace our existing identity provider?

No. The services are composable, so detection and response or verification can be adopted alongside an existing provider such as Okta or Entra ID.

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
Transmit Security: Is fraud detection an extra licence?

It is a separate service, but it is designed to run inside the authentication flow rather than as a bolted-on second vendor. Confirm which services are in your quote.

StackBlitz: Is there an Enterprise option?

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

Source
Transmit Security: Is there a way to try it?
