Are there tools that can run stateful mock servers with real CRUD behavior backed by a datastore, so our mocks remember what was created between requests?

“Best for simple persistent CRUD”

“Persistence: Mutations are written back to db.json. Records survive server restarts.”

“It's particularly convenient because you can define a data model:”

“Best built-in CRUD simulation”

“Register a resource such as /users, and it automatically generates:”

“Supports seed data and automatic ID generation.”

“Persistence: Its CRUD datastore is in-memory, so it remembers changes between requests but not across resets or restarts.”

“Offers programmable stores that let you:”

“Good when you need more sophisticated stateful behavior than basic CRUD.”

“Supports stateful scenarios, where the response depends on previous requests.”

“More suitable for modeling workflows than providing a general-purpose database-backed CRUD API.”
