The short version
- Only WeWeb has a free tier, so it costs nothing to try first.
- Each has a real cost: WeWeb there is no database, authentication provider or server-side logic layer, so a WeWeb project is always at least two subscriptions and the total cost is never the price on the pricing page.; 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: WeWeb covers Backend agnostic, Whalesync covers Two-way sync.
- Prices and features above were last checked on 31 August 2026.

What people use each for
The jobs each tool is most often brought in to do.
WeWeb
- Building an interface over data that already lives in Supabase or PostgreSQLnot Whalesync
- Agency work where the client contract requires an application that runs without the vendornot Whalesync
- Replacing the front end of a no-code application that has outgrown its original platformnot Whalesync
- Internal tools for staff where the database and its permissions already exist and must not be duplicatednot Whalesync
Whalesync
- A team that plans work in Notion but reports from Airtable and needs one edit to appear in both without anyone copying it acrossnot WeWeb
- A marketing site built in Webflow whose content is authored and managed in Airtable, kept in step continuously rather than republished on a schedulenot WeWeb
- A startup keeping a Postgres application database and an internal Airtable operations view aligned without building a sync servicenot WeWeb
- An agency keeping a client CRM and a project tracker consistent so account managers and delivery staff work from the same recordsnot WeWeb
Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
WeWeb
- There is no database, authentication provider or server-side logic layer, so a WeWeb project is always at least two subscriptions and the total cost is never the price on the pricing page.
- Self-hosting and the more useful delivery options sit on higher tiers, so on entry plans you are hosting with WeWeb and depending on its uptime for a production application.
- The learning curve is closer to a front-end framework than to a drag and drop builder; collections, bindings and state assume you understand how data flows through an interface, which defeats non-technical buyers.
- Output is web only. There is no native mobile build, so anything that must appear in the App Store needs a wrapper or a different tool entirely.
- It is a small European vendor competing against far larger platforms, so procurement teams that assess supplier viability, support depth and long-term roadmap will need convincing before signing.
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.

- Yes. WeWeb has a free tier, so you can try it without paying. Whalesync starts at $40/month.
- What is WeWeb best used for?
- WeWeb is most often used for building an interface over data that already lives in supabase or postgresql, agency work where the client contract requires an application that runs without the vendor, replacing the front end of a no-code application that has outgrown its original platform, internal tools for staff where the database and its permissions already exist and must not be duplicated.

Answered from the vendors’ own pages
WeWeb: Do I need another product to use WeWeb?
Yes. It builds the front end only. You need a backend such as Supabase, an existing database or an API before the application does anything useful.
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.
WeWeb: Can I host the app myself?
On the higher tiers, yes. That is one of the main reasons agencies choose it, because the delivered application can run without the vendor in the path.
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.
WeWeb: Is it suitable for someone who cannot code?
Less so than most no-code builders. You do not have to write code, but you do have to think like a front-end developer about state, collections and bindings.
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.
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.
