Where each one falls short

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

Merge

  • Cannot access data outside Merge's universal schema; no support for custom objects or deep field mappings
  • Merge holds customer OAuth tokens, creating vendor lock-in; switching providers requires re-authentication from all customers
  • No support for legacy systems without APIs; limited to modern SaaS applications
  • Pricing complexity at scale with multiple dimensions (workflows, tasks, connectors) affecting costs

Celigo

  • Prices are not published on any of the three editions
  • Billed on endpoints and flows, so the cost is driven by how many systems you connect rather than by volume through them
  • API Builder, lookup caching and a sandbox all require the Professional edition
  • Single sign-on is optional on Standard and included from Professional up
  • Unlimited endpoints and the full governance features are Enterprise only

Answered from the vendors’ own pages

Merge: What is a Linked Account in Merge?

A Linked Account represents an end customer's authenticated connection to a third-party application (like Salesforce, HubSpot, or Zendesk). Merge pricing is based on the number of production Linked Accounts your end users activate.

Source
Merge: Can I access custom data not in Merge's universal schema?

No. Merge works well for standardized integrations but hits limits with enterprise customers. You cannot access data outside Merge's universal schema, cannot customize integration behavior for specific customers, and cannot pull deeply custom data from source systems.

Source
Merge: What happens if I switch away from Merge?

Merge holds your customers' OAuth tokens. Switching providers means asking every customer to re-authenticate, resulting in potential customer churn and unhappy users.

Merge: Does Merge work with legacy systems?

No. Merge only works if there's an API. Legacy ERPs, government portals, insurance carriers, and older enterprise systems that customers depend on often don't have APIs, making Merge unable to support these integrations.
