The short version

  • Only Earthly has a free tier, so it costs nothing to try first.
  • Each has a real cost: Earthly pricing model not published; requires sales contact; 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: Earthly covers Policy as code, 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.

Earthly

  • Pricing model not published; requires sales contact
  • Earthly Lunar is a recent launch (2025) with limited track record
  • Primarily GitHub-focused; limited integration with other platforms
  • No public documentation on pricing or feature tiers

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

Earthly: What is the difference between Earthfiles and Earthly Lunar?

Earthfiles is an open-source build tool that reached 12,000 GitHub stars and is used by companies like NVIDIA, Intel, and Databricks. Earthly Lunar is a separate governance platform launched in 2025 for enforcing standards across development workflows.

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.

Earthly: How does Earthly Lunar enforce standards?

Lunar converts engineering standards, compliance requirements, and processes documented in AGENTS.md files, wikis, and incident postmortems into enforceable guardrails that apply consistently across repositories and development stages.

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.

Earthly: What is the pricing for Earthly Lunar?

Pricing is not published on the website. Interested customers should contact Earthly's sales team for current pricing and feature tiers.

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

Yes, a free developer tier exists for evaluation, though production use is an enterprise agreement.
