Traffic management has reduced incidents and has provided faster, more controlled releases
While our overall experience with NGINX API Gateway has been positive, there are a few areas where I feel it could be improved. One is an easy centralized management UI. A lot of advanced configuration is still heavily file-based and engineering-driven, so for larger enterprise environments, a modern, intuitive centralized management dashboard would help operational teams significantly. More built-in API lifecycle management features would also be helpful. Compared to some enterprise API management platforms, features such as developer portals, API monetization, and version lifecycle management are not as comprehensive out-of-the-box. Configuration complexity at scale is another concern. As an environment grows, managing large configuration files across many services can become difficult. We handle this through automations and templating, but it still requires an experienced engineer. The learning curve for advanced tuning also presents challenges. The basic setup is straightforward, but optimizing performance, caching, and traffic strategies for higher traffic requires deep expertise. In our case, none of these are blockers, but improving these areas would make the platform even more enterprise-friendly and easier to operate at a very large scale. A few additional improvements come to mind regarding NGINX API Gateway. One area is documentation for advanced enterprise use cases. The basic setup documentation is quite good, but when dealing with complex traffic routing, multi-region deployments, advanced caching strategies, or large-scale Kubernetes integrations, teams often need to rely heavily on community forums and internal experimentations. More real-world architecture examples and enterprise deployment patterns would be very helpful. Support response quality can also vary depending on the complexity of the issue. For standard operational problems, support is generally responsive, but for highly specific performance tuning or advanced configuration challenges, resolution sometimes requires deep internal troubleshooting from the engineering team. Another improvement area is operational visibility. While integration with monitoring tools works well, having more built-in dashboards for traffic analytics, latency trends, upstream health, and API usage would reduce dependency on external observability platforms. Finally, although performance is excellent, onboarding newer engineers can take some time because advanced NGINX API Gateway configurations and migration patterns require fairly strong infrastructure knowledge. More guidance, templates, automation recommendations, and best-practice deployment blueprints would make adoption easier for a growing team.

In my opinion, OPNsense could improve by incorporating either an open side of wireless management or a way that you can also manage your interconnected devices. You could easily have SNMP, Simple Network Management Protocol, incorporated in it so that you can easily manage the devices and easily get the information about the devices that you are managing. Additionally, the inclusion of Pi-hole would allow you to create an ad-free network instead of adding it on a separate device. I would prefer that incorporated into OPNsense, or if it is there, I would appreciate guidance on how to use it.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"We do not face any lags."
"We use it for container deployment, mostly for Kubernetes, and sometimes we also use it for testing purposes as I am using it for my own personal learning purposes."
"It's easy to install, and the performance is good."
"API routing is the most valuable feature."
"NGINX API Gateway has been a reliable and high-performance platform for our organization, providing an excellent balance between performance, flexibility, and operational efficiency while handling large API traffic very well and remaining lightweight and relatively cost-effective compared to some heavyweight enterprise solutions."
"The best features of NGINX API Gateway are the authentication aspects, since it adds a barrier to your application before requests hit the main service, and also the load balancing aspects where it handles system downtimes by routing requests to the next available service."
"The system in general is quite flexible."
"Its pricing is unbeatable in comparison to other firewalls."
"Its user interface is one of the best interfaces I have used."
"The initial implementation process is simple."
"I find the solution to be user-friendly. It has a lot of reports and easy settings."
"We have found pretty much all the features of the solution to be valuable."
"The DNS-level filtering is impressive for thwarting time scanners."
"I feel that its valuable features are that it is simple and free."
 

Cons

"While our overall experience with NGINX API Gateway has been positive, there are a few areas where I feel it could be improved."
"I believe NGINX API Gateway could improve by offering token authentication in the normal version instead of only in NGINX Plus, as it currently requires migration to enterprise for that feature."
"The product must improve its security features."
"The UI could be more attractive."
"It could be more secure because security is always a problem."
"I confirm that I am currently still working with OPNsense and still using their product. However, because of the hardware that I am using, sometimes it ends up freezing quite often, especially the interfaces, most of the busy interfaces."
"Given that OPNsense plays a pivotal role as a firewall, safeguarding against various threats, having a reliable backup ensures uninterrupted protection even if unforeseen events impact the primary virtual machine."
"The scalability needs improvement."
"My mark for OPNsense technical support is a four for the free version since they do not care when they realize you are using the free version; they just ghost on you."
"You will need additional training before you can actually start to use it."
"There are issues with stability and reliability."
"The solution could be more secure."
"I think the most important thing is that it should be easily accessible, but currently, that doesn't seem to be the case. We need a hardware platform that's based on common standards and open computing principles, which would be like a commodity and benefit us greatly."
 

Pricing and Cost Advice

"We are using the open-source version."
"We are using the open source version, so there is no cost involved."
"It is free."
"It is not an expensive product. Basically, I deployed it because it was the fastest solution to satisfy our needs in open source."
"It's not expensive."
"I'm using the free version of OPNsense. I didn't check the pricing for the solution because I still need to test it before getting the approval to purchase OPNsense, and it isn't easy to get approval from the higher-ups."
"As an appliance, it's in the medium price range."
"There are no licensing costs for OPNsence."
"The price of OPNsense is good."
"OPNsense is a well known open-source tool."
