MockBase

No. You can create up to three mocks with up to ten routes each anonymously and call them 2,000 times a month. Signing in with GitHub or Google lifts that to unlimited mocks and routes, unlocks callouts and Record & Replay, and — during the beta — gives you Pro's 20,000 request monthly quota for free.

Those run on your machine. That is genuinely better if everything happens on one laptop and you never need a shared URL — Mockoon is free and offline forever. MockBase is hosted, so the endpoint is reachable by a teammate, a phone, or a CI job the moment you make it, and it adds conditional matching, templating, stateful CRUD, chaos scenarios, and a live inspector on top. We wrote an honest comparison for Mockoon, Beeceptor, WireMock, Postman, json-server, and Apidog, including where each of them wins.

Yes. GraphQL requests all share one path and method, so MockBase routes on the operation name — read from operationName, or parsed out of the query text when the client doesn't send one. SOAP works the same way: match on an element inside the XML envelope by name, ignoring namespace prefixes, and return a raw XML envelope. There is no WSDL parsing and no gRPC.

Yes, and in more than one shape. Chaos injection fails a percentage of requests using weighted scenarios you define — a slow gateway timeout, a truncated body, an empty response, or a genuine connection reset (the client sees the connection die before a body arrives, the same as a crashed backend). Rate limit simulation is separate and deterministic: after N requests in a window, every further one gets a 429 with a Retry-After header. Both can run on the same route.

Every save snapshots the previous state automatically. The version history keeps 30 versions per mock for 90 days, shows what restoring one would add, remove, or change before you click, and restoring is itself undoable. You can also take a named snapshot on purpose before a risky set of edits.

Yes. Generate a personal API key from Account → API keys, then either use it with mockbase-cli (a dependency-free script that pushes a JSON config file to create or update a mock, and pulls one back into a file) or point an MCP server at it so Claude Desktop or Claude Code can create, edit, and inspect a mock's traffic directly. Both are documented at /docs/mock-as-code and /docs/mcp-server.

A higher monthly request quota: 20,000 instead of 500. Every feature — custom subdomains (acme.mockbase.org), token-protected endpoints, chaos injection, callouts and Record & Replay — is available on the free plan too (callouts and Record & Replay need a signed-in account). During the public beta every signed-in account gets the Pro quota at no cost and without a credit card.
