One feature I found most valuable in Apigee is its simplicity. All features remain the same in all of the API tools, and I have experience with IBM API Connect and Apigee, but Apigee is easier to work with, plus the learning curve is not that steep.
Another thing I like about this solution is that the support is really good, and this gives Apigee advantage over other providers.
I like the development feature of Apigee. You will find it easier to work with Apigee than IBM API Connect.
We found a glitch in Apigee, and we raised it with them: It's the response overlapping from the API with high traffic.
They have been working on that, and they have shared a patch with us, but I'm not sure if that is publicly available for all users. It was made available to our organization: one single patch of Apigee.
I've been using Apigee for over two years, and I've used it in the last 12 months.
This product is is stable.
Apigee is a scalable product.
Technical support for Apigee is very good.
I used IBM API Connect, but found it easier to work with Apigee.
I evaluated IBM API Connect.
I'm both a user and an integrator of Apigee.
We have deployments both on-premises and via cloud. We use both, like Google SaaS and the on-premises solution.
We are a consultant for different organizations. Some organizations prefer on-premises deployment, with everything on their private cloud, and this means they use the older version of Apigee. Some organizations use the latest version because they're using Google SaaS directly.
My advice to people who are looking into implementing Apigee in their organization: If it fits your budget, then it is a good product. If it fits into your ecosystem, e.g. you are in that ecosystem, not in IBM or other CA-based ones, Apigee is something you can go for. It is a good platform.
I haven't worked with CA, and there are others, e.g. MuleSoft, so I can't comment on how Apigee compares with those competitors, but compared to IBM API Connect, Apigee is a good one.
I'm rating Apigee eight over ten. There's still room for improvement, so it's an eight for me.
