The short version

  • Only ToolJet has a free tier, so it costs nothing to try first.
  • Each has a real cost: ToolJet free and Pro tiers cap end users at 50, which may be too low for apps needing broad internal distribution.; 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: ToolJet covers Drag-and-drop app builder, 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.

ToolJet

  • Free and Pro tiers cap end users at 50, which may be too low for apps needing broad internal distribution.
  • Enterprise pricing starts at a steep $3,000/month, a large jump from the $199/month Team plan.
  • AI credits reset monthly and do not roll over, penalizing uneven month-to-month usage.
  • Smaller integration and community ecosystem than more established players like Retool.

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

ToolJet: What happens if I run out of AI credits?

Users can continue using all other ToolJet features as normal and can contact support to purchase additional AI credits when the monthly allotment runs out.

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.

ToolJet: Do unused AI credits roll over?

No, AI credits reset every month and unused credits do not carry over, which ToolJet says helps maintain consistent service quality.

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.

ToolJet: Can ToolJet be deployed on-premise?

Yes, both the community and enterprise editions support on-premise and air-gapped deployments, typically completed in under 30 minutes.

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.

ToolJet: Is there a free trial for paid plans?

ToolJet offers a 14-day free trial for both its business and enterprise editions.

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.
