"Open-Source API Testing Made Effortless"

4.5/5

What do you like best about Mockoon?

I like that Mockoon is open source and free, so I don't need to sign up for an account and re-login many times. The app is not overloaded and seems pretty responsive, so it doesn't slow down my work. It's fast and doesn't have the annoying logouts and lags that I experienced with other tools. Review collected by and hosted on G2.com.

What do you dislike about Mockoon?

Maybe small parts of UI can be improved, like better tooltips. Maybe improving documentation may help too Review collected by and hosted on G2.com.

"Easiest tool to mock REST APIs"

5/5

What do you like best about Mockoon?

The tool is pretty straightforward; the best part is it's free and open-source. Review collected by and hosted on G2.com.

What do you dislike about Mockoon?

It's good overall, but the only thing is very few user-experience documents available on the internet. Review collected by and hosted on G2.com.

What problems is Mockoon solving and how is that benefiting you?

Mockoon is a free, easy-to-use tool for API mocking. With Mockoon, we can quickly mock third-party API calls locally for REST API testing. As API engineers, it saves us a lot of time and energy while doing testing. These third-party API calls take a lot of time, so testing our in-house APIs becomes a task, and so mocking ensures a fixed response time. In short, mockoon provides this medium to mock those third-party calls taking too long. Review collected by and hosted on G2.com.

"A must have for every backend developer"

4/5

What do you like best about Mockoon?

Mockoon is really useful for mocking APIs quickly and easily. It can create an unlimited number of mock APIs and routes. It can create multiple mock responses for each API endpoint if the user does not have access to the remote server's API. Review collected by and hosted on G2.com.

What do you dislike about Mockoon?

The user interface can be intimidating for first-time users, but once the user gets the hang of it, it will save a lot of time to create APIs, especially for backend developers. Review collected by and hosted on G2.com.

"Useful mock REST Apis creation software!"

4.5/5

What do you like best about Mockoon?

Mockoon is completely free to use unlike many other applications in the market to test the REST Apis without deployment of the application which needs to be created. Review collected by and hosted on G2.com.

What do you dislike about Mockoon?

Mockoon does not have a very good-looking user interface and sometimes it becomes difficult for a developer who is new to the field of APIs to use it. It also takes a lot of time sometimes to create a new environment. Review collected by and hosted on G2.com.

"Very handy while developing applications for efficient integration of front-end and back-end parts"

5/5

What do you like best about Mockoon?

Mockoon is very helpful for front-end developers to integrate and ensure compatibility of their projects with the back-end being developed.

The application gives a lot of customizability for creating Mock APIs for testing the functionality of our application as per the requirements and schemas followed. Review collected by and hosted on G2.com.

What do you dislike about Mockoon?

The software doesn't have much to dislike; however, it can consume quite a bit of memory if left running for a while. However, the effect on performance can be improved by efficient planning of requirements and APIs to execute. Review collected by and hosted on G2.com.

Recommendations to others considering Mockoon:

If you build an application where different teams are creating other parts of the project simultaneously, this software will save a lot of hassle and time. Review collected by and hosted on G2.com.

What problems is Mockoon solving and how is that benefiting you?

I used Mackoon a few months ago while working on a Vue.js project as a participant in a Hackathon.

In a restricted environment where building the project in a constrained time is very important, it helps a lot by creating mock APIs while actual APIs are being developed. Review collected by and hosted on G2.com.
