The short version

  • Only Moonrepo has a free tier, so it costs nothing to try first.
  • Each has a real cost: Moonrepo smaller community compared to established build systems like Bazel; Sardine signal quality depends on the SDK being embedded in your own web and mobile clients, so fraud improvements become dependent on your app release cycle and any coverage gap is a blind spot.
  • They diverge on capability: Moonrepo covers Task orchestration, Sardine covers Device intelligence.
  • 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.

Moonrepo

  • Smaller community compared to established build systems like Bazel
  • Limited integrations with enterprise CI/CD platforms
  • Documentation gaps in some advanced use cases
  • No commercial support option for organizations requiring guaranteed SLAs

Sardine

  • Signal quality depends on the SDK being embedded in your own web and mobile clients, so fraud improvements become dependent on your app release cycle and any coverage gap is a blind spot.
  • Behavioural and device telemetry collection needs a documented lawful basis under GDPR, and EU privacy reviews frequently delay rollouts that were scoped as engineering work.
  • Pricing is per session or per active user, so a consumer product with many low value sessions pays in proportion to traffic rather than to fraud exposure.
  • As a younger private company it lacks the enforcement-tested audit history that a bank examiner expects, which makes it a harder sell inside a regulated bank than inside a fintech.
  • It is strongest on session-time signals and weaker as a system of record for long horizon AML typologies, so larger institutions end up running it alongside a traditional monitoring platform rather than instead of one.

Source
Sardine: Does Sardine do document verification?

It focuses on device, behavioural and transaction signals, and integrates identity verification providers rather than being one. Treat it as complementary to a KYC vendor.

Moonrepo: Is Moonrepo suitable for large monorepos?

Yes, Moonrepo is designed to scale to monorepos of any size with intelligent caching and task orchestration to maintain build performance.

Source
Sardine: What does it need from us to work?

An SDK in your web and mobile applications plus transaction feeds. Without the client side collector you lose the signals that differentiate it.

Moonrepo: Can I use just moon or just proto separately?

Yes, moon and proto are independent tools that can be adopted separately or together to address specific team needs.

Source
Sardine: Is pricing published?

No. It is quoted, typically per session or per monthly active user with an annual volume commitment.
