General Questions

What is is a Mock-As-A-Service solution. It provides tools that allow you to set up, manage, and troubleshoot your HTTP protocol API mocks in the cloud. This frees you up to focus on the logic of your mocks and not have to think about boilerplate code, infrastructure, hosting, and hardware maintenance. Changes made in your mocks are immediately available for mock clients, so you don't have to wait for time-consuming deployments of self-hosted mock services. supports a broad spectrum of use cases that allow the mocking of not only simple, static services but also complicated, dynamic ones.

What can I do with allows the mocking (simulation) of services exposed through the HTTP interface. The most common type of such services is RESTful web services., however, does not force any specific protocol/patterns to be used. You define matching rules for HTTP requests and specify what response to return when the request matches. You may simulate RESTful, SOAP, or any other services exposed through HTTP.

Does Smartmock support dynamic responses?

Yes - provides two ways to implement dynamic mocks. These are Template Mocks and Dynamic Mocks. Template Mocks use Moustache notation to include dynamic data in your mock's responses. Dynamic Mock is just Javascript code that renders an HTTP response (status code, headers, body). Please see our documentation for more information about Template and Dynamic Mocks.

Is there a way to simulate stateful behavior in Smartmock?

Yes - supports the concept of state which allows the simulation of stateful behavior. Please see our documentation for more information about states.

What is a workspace?

A workspace is a container for mocks and is identified by a unique URL. You'll use that URL to send requests to your mocks. We encourage you to treat a workspace as a contained environment for a single service/API/application you'd like to simulate. Doing this simplifies the management of workspaces and mocks. You may, however, merge many services/APIs into individual workspace if required.

Can accounts be merged? accounts cannot be merged from the user interface. If you and other users are from the same company and wish to consolidate your accounts, please consider signing up for a Large Plan and contact our support. We'll help you move your workspaces and mocks to the new account.

Can I change the owner of an account?

Changing the owner of an account or a team is currently not possible from the user interface. Please contact our support to request change of ownership.

Why is better than a self-hosted mock service? is an excellent example of a service where you may outsource some of your team duties. Maintaining self-hosted mocks usually consumes a considerable amount of time and effort. While creating self-hosted mocks, your team members need simultaneously to implement not only business logic but also choose frameworks and tools, and write lots of boilerplate code for logging, instrumentation, and setting up the infrastructure. Self-made mocks are often not as reliable and as well tested as production services which consumes additional time for troubleshooting and fixing problems. With you only focus on your mocks’ business logic.

I get an internal server error (HTTP 500) when requesting a mock endpoint. How can I troubleshoot the problem?

For each workspace, provides a console which shows the results of the last 100 requests made. You may inspect the cause of an error there. Usually, such errors appear for incorrect expressions in Template or Dynamic Mocks. You may also contact our support if you cannot diagnose the problem on your own.

Is GDPR Compliant?

Yes! is committed to customer privacy and is GDPR Compliant.

If you don't remove excessive entities after a week, they are removed automatically (youngest objects deleted first).
