The short version

  • Only RoboForm has a free tier, so it costs nothing to try first.
  • Each has a real cost: RoboForm free plan is restricted to a single device; syncing across multiple devices requires the Premium plan; 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.
  • 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.

RoboForm

  • Free plan is restricted to a single device; syncing across multiple devices requires the Premium plan
  • Premium's advertised $2.49 per month rate is a first-year discount that renews at $29.88 per year
  • Family plan covers only up to 5 accounts and likewise renews at a higher $47.75 per year after the first-year discount

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.
