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

StackBlitz

  • Specific Teams and Enterprise pricing figures are not published; visitors must request a quote or infer from the pricing calculator.
  • Browser-based execution via WebContainers has limits on which native/binary dependencies can run compared to a real server-backed environment.
  • Heavy or resource-intensive workloads may be constrained by the end user's own browser and machine resources.

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
StackBlitz: Is there a free plan, and what are its limits?

Yes, the free Personal plan includes unlimited public StackBlitz projects, collections, and GitHub repositories, and lets anyone view and edit projects without needing a GitHub account.

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
StackBlitz: What does the Teams plan add?

Teams lets GitHub organizations add free or paid members; paid members get access to private collections and repositories, with permissions mirrored from GitHub-owned repos.

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.

StackBlitz: Is there an Enterprise option?

Yes, custom Enterprise plans are available and require contacting StackBlitz directly.

Source
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.
