ROI

Sentiment score
5.5
IBM API Connect enhances efficiency and flexibility, reducing service exposure time and enabling data monetization with significant ROI improvements.
Sentiment score
5.4
Kong Konnect boosted debugging efficiency, reducing costs and downtime, while enhancing API performance, deployment speed, and security management.
Reducing development hours from eighty to four for an API was possible due to reusing existing scripts from DataPower.
Software Engineer IV at Royal Cyber Inc.
I have seen a return on investment from using IBM API Connect, as we created multiple plans based on customer usage.
Works at a outsourcing company with 5,001-10,000 employees
Time saved is a relevant metric; it used to take us a week, but now it takes us only a day.
Lead Software Engineer at a computer software company with 51-200 employees
I have seen a return on investment with Kong Konnect, as it helps manage security very well, allows for faster API deployments saving developer time, and reduces salary costs with better uptime and minimal downtime, thus preventing potential business loss.
Open Shift Engineer at Dhanyaayai enterprise private limited
Our debugging time during regression cycles reduced roughly by 25% to 30%, mainly because the gateway layer helped us quickly identify whether issues were coming from authentication policies, rate limiting, throttling, or the backend services.

Room For Improvement

IBM API Connect needs better monitoring, integration, user experience, and DevOps tools, while facing complaints about cost and complexity.
Kong Konnect needs improved debugging tools, documentation, UI, RBAC, pricing, CI/CD integration, and beginner-friendly features.
Examples include the lack of connectivity to MQ.
Software Engineer IV at Royal Cyber Inc.
You need to know when traffic peaks, so use auto-scaling when traffic comes.
Works at a outsourcing company with 5,001-10,000 employees
Connectivity to MQ is not available in IBM API Connect.
Software Engineer IV at a financial services firm with 1,001-5,000 employees
A bit more granular and easily accessible logs would make troubleshooting faster.
Software Development Engineering Testing at HighLevel
The licensing model could be simplified, especially in how they charge and track usage.
IT Soulutoin Expert at a tech vendor with 10,001+ employees
When comparing documentation, Kong's documentation is not on par with Google, Amazon, or other cloud providers.
API Technical Architect at Independent API Consultant
 

Setup Cost

IBM API Connect offers tiered pricing with robust features, seen as cost-effective despite higher costs compared to competitors.
Enterprise users have mixed reviews on Kong Konnect's pricing, citing initial appeal but potential high long-term costs.
Pricing depends on how many instances run across environments.
Software Engineer IV at Royal Cyber Inc.
Pricing was the issue as it becomes very expensive due to the nature of local circumstances.
Senior Software Engineer at Netenrich
While the pricing model isn't very clear on how usage is tracked, the initial cost and setup for using Kong Konnect are reasonable.
IT Soulutoin Expert at a tech vendor with 10,001+ employees
I purchase it from Kong vendors, not from the cloud marketplace because the cloud marketplace has a limitation on the number of API services it supports.
API Technical Architect at Independent API Consultant
 

Valuable Features

IBM API Connect offers comprehensive API lifecycle management with user-friendly development, security, analytics, and cloud integration features.
Kong Konnect offers centralized API management, analytics, and security, enhancing productivity with easy integration and scalable hybrid architecture.
It offers significant development efficiency, reducing man-hours from eighty to four when creating APIs.
Software Engineer IV at Royal Cyber Inc.
We can add some policies to provide extra security, protect your backend, validate the consumers, and analyze based on the traffic limit to throw things out.
Works at a outsourcing company with 5,001-10,000 employees
IBM API Connect has a designer and CLI features which can be used to completely automate the API.
Software Engineer IV at a financial services firm with 1,001-5,000 employees
The documentation is excellent, and it includes a developer portal, which helps create a common distribution channel for APIs within and outside the enterprise.
IT Soulutoin Expert at a tech vendor with 10,001+ employees
When I mention scalability, it means that when we experience peak traffic, Kong made it easy for us to scale and spawn new machines.
Lead Software Engineer at a computer software company with 51-200 employees
The security features of Kong Konnect have helped my team mainly by allowing us to use auth and JWT for applications needing external identity provider authentications, such as LDAP or other authentication providers that need to be connected to back-end applications.

API management has strengthened security and monitoring but still needs better support and tooling
There are areas of IBM API Connect that need to be improved. I want what Gravitee made, which is much better. Gravitee made many samples for different use cases. First of all, they made examples of use cases, codes, and what the module expects and what the module returns for multiple examples and use cases inside the development. I do not even have to go to the documentation website because everything is included inside the tool when I work on it. This is great, in fact. IBM API Connect should show examples. One other thing is the support. The support of IBM is in India. Every time I want to ask something, they say they need logs, they want this, they want that. Gravitee API asks me to explain the problem without asking a thousand times as if it is a request for a green card in the USA. Then they really explain quickly. IBM is a big company, so everything is standardized with the approach of "You do that, you do that, you request that. If you do not have that, you do not reply to the client." Clients want flexibility today, even if it is a huge company. A stressed client is a client that will want to change to other flexible solutions. When everything is fine, we do not care, but when there is stress and problems, that is when the customer of IBM evaluates the tool really. It is when there are problems. IBM makes a lot of efforts on sales and technical sales, and then that is it.

Centralized gateway testing has improved debugging speed and validates real-world API behavior
Kong Konnect requires some improvement, but overall the experience is quite positive. One thing I can think of currently is around debugging visibility. While I know that the analytics are helpful, sometimes getting very detailed request-level insights during failures, especially in CI runs, required additional digging. A bit more granular and easily accessible logs would make troubleshooting faster. Also, in some cases, configuration changes were not immediately intuitive to validate from a testing standpoint. Having better tooling or previews to simulate how a policy change would impact API behavior could be useful. Nothing major, but these kinds of improvements would make it even more efficient for teams, especially our teams, which heavily rely on automation and CI pipelines. Better integration visibility with CI/CD tools would make it easier to quickly correlate test failures and gateway behavior without switching between multiple dashboards. This should be improved.
