Top 5 Mock API Tools

Top 5 Mock API Tools

There are multiple tools available for mocking our API, creating endpoints, returning responses, changing status codes, etc. However, there can be significant differences among them if we analyze their functionalities and the interface they provide for us to work with them.

Let’s take a look at what we consider the 5 best tools for creating a mock server, taking into account their interface, ease of use, whether they have a free plan or not, and finally, their pricing if they have a paid plan.

Here is our top 5 list of mock API tools:

5. Beeceptor

Beeceptor is one of the most popular tools for mocking an API. If you search on Google, it will probably be one of the first tools you find for creating a mock server. While it's true that it doesn't stand out for its interface, it is quite simple, though not the most attractive. Creating an endpoint is straightforward but becomes more complicated when you want to edit it, as it's not as user-friendly as some of its competitors.

It has some interesting features, such as showing requests to your mock server in real time, and it offers comprehensive documentation.

Regarding the free tier, Beeceptor is a bit limited since it only allows you to have 1 endpoint with 50 requests per day. Compared to its competitors, it is very limited and falls short.

As for the paid plan, the cheapest starts at $10 per month and allows you to have 15k requests per month, which translates to only 500 requests per day per endpoint. It’s still quite limited, but if you only need a mock server for occasional testing, it might be a good option.

4. Mockapi.io

Mockapi.io is a tool for creating mock endpoints that is very attractive and easy to use. It has a simple yet well-designed style and allows you to create a mock server in very little time. Its interface relies more on using the graphical interface to define your mock endpoint response rather than a code editor, which can be somewhat tedious if you want to do something more complex. But if you're looking to quickly and easily mock an endpoint, it's one of the best mock server tools you can find.

3. Postman

Although we typically know Postman as a client for making API requests, it also has a feature that allows us to create a mock server. Given its numerous functionalities, it can be a bit cumbersome to use it solely as a mock server, but if you're already using it for making requests or documenting your API, it can be a good option as a mock API tool.

Its interface is very comprehensive and complex because, as we've mentioned, it has a lot of functionalities, but once you get the hang of it, creating a mock server is fairly straightforward.

It does not offer a free plan for mock servers, which is a significant downside, but many companies already pay for a premium Postman plan, so it might be worth using it as a mock server if you're already paying for it.

If you aren't paying, the cheapest plan that includes a mock server is the Basic plan at $14 per month, which allows you to make up to 10k requests per month.

2. Mockoon

Mockoon is a super intuitive and easy-to-use tool for creating a mock API, and it's also open-source. One of its biggest limitations is that it works locally, which makes it difficult to share your mocks easily with coworkers or others. However, it has a great interface and a ton of features that make creating a mock server quick and easy. Plus, since it works locally, you won’t need an internet connection to use it.

Mockoon is free, but it does have a paid version that deploys in the cloud, which solves the problems we mentioned earlier. It's called Mockoon Pro and allows you to share your mock API with others. The price starts at $15 per month and includes 50k requests per month, which is a bit pricey compared to its competitors.

1. Mockfly

For us, Mockfly is the best tool available on the market for creating a mock API. It has everything we look for in a mock server: a beautiful and simple interface, ease of use, and the functionalities we need when creating a mock server, such as generating random data, latency, etc.

Moreover, it has one of the most competitive free plans that allows you to try and use the tool without having to pay anything for your personal projects, offering 500 requests per day and 4 endpoints. In other words, compared to other tools that provide 15k requests per month with payment, Mockfly gives you 15k requests per month for free.

If you need something more professional, Mockfly's pricing is among the cheapest compared to its competitors, as for $8, you get unlimited requests to your mock server and unlimited endpoints to create your mock API.

For these reasons, Mockfly seems to us to be the most complete and competitive tool for creating a mock server, and that's why we put it in the first place.
