The short version

  • Only Avo has a free tier, so it costs nothing to try first.
  • Each has a real cost: Avo editor seats are the metered unit and only five are included on the Team plan, so a company where many squads define their own events pays 50 dollars per additional editor and the real cost quickly exceeds the headline 250.; 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: Avo covers Tracking plan, 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.

Avo

  • Editor seats are the metered unit and only five are included on the Team plan, so a company where many squads define their own events pays 50 dollars per additional editor and the real cost quickly exceeds the headline 250.
  • Avo governs event definitions but does not fix historic data, so an organisation with years of inconsistent tracking still faces the backfill problem it cannot solve.
  • Code generation requires engineering teams to adopt generated modules in their build, and in practice some platform teams resist, leaving parts of the estate ungoverned and the plan only partly enforced.
  • Inspector event volume is capped by tier, at 100,000 on free and one million on enterprise, so a high-traffic consumer product samples rather than observes everything and drift can hide in the unobserved portion.
  • It is an additional tool in an analytics stack that already costs money, and justifying it requires the organisation to accept that its existing data is unreliable, which is a political argument as much as a budgetary one.

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.

Answered from the vendors’ own pages

Avo: Is the free tier usable in production?

Yes. It includes two editors, code generation and 100,000 events observed in Inspector, which is enough for a small team.

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.

Avo: What exactly does code generation give me?

Type-safe tracking functions per platform, so a wrong event name or property type fails at compile time rather than in production data.

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.

Avo: Does Avo replace Amplitude or Mixpanel?

No. It governs the events those tools receive; you still need an analytics product.

Sardine: Is pricing published?

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

Avo: How much is the Team plan?

250 US dollars a month billed annually for five editors, or 300 billed monthly, with extra editors at 50 dollars.
