How to Pick the Right Open-Source API Management Platform?

1. Features

When it comes to finding an answer to ‘how do you choose the best API management (APIM) solution’, the foremost factor to consider is the features of API management platforms.

Every open-source API management tool has specific requirements and implementation limitations. So, performing an API management platform comparison in terms of your technical and non-technical requirements can be really helpful.

2. Deployment Complexity

When it comes to deployment, some gateways require a single node while others run on multiple types of nodes for setting up a database. Besides, some gateways operate with many databases, which can be a complicated thing to manage.

So, focusing upon the deployment complexity can also help you with finding the right API management open source tool.

3. On-Premise vs Cloud hosted

On-Premise tools, as depicted from the name, are located within the physical premises of a company. One can add more time to the deployment and maintenance process. 

But, in the case of Cloud-hosted, the API management open source tools are located at a virtual location and its services are made available via Cloud computing. They can introduce more latency due to the extra hop and even lower down the availability of your service when the vendor goes down.

So, analyzing the pros and cons of both the options to determine which open-source API management tool to embrace can also be a profitable idea.

4. Community Support

Last but not least, having an idea of the type of community support each API management open source tool  needs also helps in choosing the right one. The larger and active a community is, the higher are the chances of receiving updates and solutions to your queries; ultimately resulting in a better experience.

With this, we have gone through the list of 20 best Open-source API management platforms and the approach to find the best one. The next step is to actually put this information into practical solutions, aka, employ an open-source API management tool into your mobile project.
