Question 1

Is Mock-Lab free to use?

Accepted Answer

Yes! Mock-Lab is a free developer productivity suite. You can use the Mock API generator, JWT Simulator, and other tools without creating an account or paying a subscription.

Question 2

How does the Mock API Generator work?

Accepted Answer

Our Mock API Generator allows you to define a JSON schema and instantly get a working endpoint. You can simulate real-world scenarios like API latency, error states (404, 500), and pagination to test how your frontend handles them.

Question 3

Is my data private?

Accepted Answer

Absolutely. We are privacy-focused. For tools like the JWT Simulator and JSON formatting, processing happens locally in your browser when possible. For the Mock API, we only store the endpoint configuration you explicitly save.

Question 4

Can I use this for production testing?

Accepted Answer

Mock-Lab is designed for development and testing environments. While our infrastructure is reliable, we recommend using it primarily for prototyping, unit tests, and local development workflows.

Question 5

Do I need to install anything?

Accepted Answer

No. All tools run directly in your browser. There are no CLI tools, SDKs, or backend dependencies to install. Just open the URL and start debugging.
