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
Temporal: What programming languages does Temporal support?

Temporal provides native SDKs for Go, Java, .NET, PHP, Python, Ruby, Rust, and TypeScript.

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
Temporal: Can I run Temporal on-premises or self-hosted?

Yes. Temporal is available as open-source software under the MIT license, allowing self-hosted deployment. Temporal Cloud is also available as a managed service alternative.

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.

Temporal: What is included in the free tier?

$1,000 in free credits for new users to explore Temporal Cloud. Self-hosted Temporal is available free with full platform functionality.

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.
