The short version

  • Only ProtoPie has a free tier, so it costs nothing to try first.
  • Each has a real cost: ProtoPie the free plan allows 2 prototypes, 8 scenes per prototype and 50MB of cloud storage; Whalesync pricing counts records held in sync rather than changes made, so a large but rarely edited catalogue costs the same as a highly active one and the economics punish exactly the datasets that need the least work.
  • They diverge on capability: ProtoPie covers Interactive prototyping, Whalesync covers Two-way sync.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

ProtoPie

  • The free plan allows 2 prototypes, 8 scenes per prototype and 50MB of cloud storage
  • Free prototypes carry a watermark and shareable links require the Basic plan
  • Saving prototypes locally requires the Pro plan
  • Team libraries and handoff recordings require the Pro plan
  • Basic caps storage at 500MB and prototypes at 20
  • Single sign on, private servers, custom fonts and custom hardware integrations are Enterprise only
  • Enterprise requires a minimum of 3 seats and is priced by quote
  • Connect Core is a paid add on at $20 per user per month

Whalesync

  • Pricing counts records held in sync rather than changes made, so a large but rarely edited catalogue costs the same as a highly active one and the economics punish exactly the datasets that need the least work.
  • The gap between the 1,000 record starter tier and the million record higher tiers is very wide with no published intermediate price, so a business at ten thousand records cannot tell what it will pay without contacting the vendor.
  • Bidirectional sync has conflict semantics, and when two people edit the same field in two tools within a sync interval one edit is lost, which is silent and only discovered when someone notices their change reverted.
  • It is a small company holding a live connection in the middle of operational data, so continuity risk is real and any team relying on it should keep an export routine and know how it would rebuild the mapping.
  • It syncs records between tools but does not transform or model data, so anything requiring aggregation, deduplication or business logic between the two ends still needs a separate tool or a warehouse.

Answered from the vendors’ own pages

ProtoPie: How much does ProtoPie cost?

ProtoPie offers a free plan ($0/month), Basic at $25/month, and Pro at $47/month per editor. Annual billing offers up to 26% savings. Enterprise pricing is custom for minimum 3 seats.

Source
Whalesync: How is this different from Zapier?

Zapier triggers one-way actions. Whalesync maintains a persistent mapping between two copies of a record so edits flow both ways without loops or duplicates, which two zaps cannot achieve reliably.

ProtoPie: Is there a free version of ProtoPie?

Yes. The free plan includes 2 prototypes, 8 scenes per prototype, and 50MB cloud storage. Perfect for trying the platform.

Source
Whalesync: What counts as a record in sync?

A record becomes counted the first time it syncs, and records are not double counted across the two applications, so a thousand paired rows count once rather than twice.

ProtoPie: What is included in the Pro plan?

Pro plan at $47/month includes unlimited prototypes, unlimited handoff recordings, 5GB team storage, local saving, and team libraries per editor.

Source
Whalesync: Is there a free plan?

No, only a seven day trial. Paid plans start around 40 US dollars a month for a thousand records.

ProtoPie: What add-on products does ProtoPie offer?

Connect Core ($20/month per user), Connect Enterprise and Connect Embedded (custom pricing), and User Testing (custom pricing, annual-only for Pro plan users).

Source
Whalesync: What happens on a sync conflict?

One side wins and the other edit is discarded. Teams that expect simultaneous editing of the same fields in two tools should establish an owning system per field rather than relying on the sync to arbitrate.
