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

ROI

Sentiment score
6.1
Cloudflare improves performance, security, and financial outcomes with affordable plans, enhancing user satisfaction and operational efficiency significantly.
Sentiment score
7.1
HAProxy's open-source load balancer cuts costs, boosts efficiency, improves uptime, reduces staffing, and enhances scalability for users.
For the small project I was working on, using the basic tier provided a huge improvement at zero cost.
Security Specialist at a tech services company with 1,001-5,000 employees
In terms of return on investment with Cloudflare, it costs my time to set them up, but basically once they're set up, it's done.
Owner at Hga consulting
Operational efficiency has improved; we no longer have staff consistently monitoring backend servers during deployment or scaling events, as HAProxy's health checks and hitless reloads allow us to push changes with minimal manual intervention.
Junior System Administrator & DevOps at a tech services company with 11-50 employees
This resulted in a drastic decrease in costs and, at the same time, the accuracy of the hits coming on HAProxy was almost around 100% or 99.99%.
Head of DevOps at TripFactory
I estimate seeing a return on investment with HAProxy, as it significantly reduced staff requirements and enhanced scaling capabilities, particularly when transitioning from NGINX, which faced issues.
Principal Engineer Manager at a manufacturing company with 501-1,000 employees
 

Customer Service

Sentiment score
6.9
Cloudflare's customer service is praised for promptness, but technical support feedback varies, especially favoring Enterprise tier users.
Sentiment score
6.5
HAProxy's customer service and technical support are highly rated for quick, expert assistance, though documentation could improve.
Cloudflare does not offer hands-on technical support to fix customer problems but rather a self-service model.
Senior Consultant CDN at a comms service provider with 10,001+ employees
I would rate the technical support with Cloudflare as excellent every time I've had to call them.
Owner at Hga consulting
We use other solutions where support is available through Slack channels and is more interactive, with someone responding within a couple of minutes or seconds.
General Manager at bKash Limited
Since we are utilizing the open-source edition, community forums, mailing lists, and GitHub have been invaluable, with typically someone having encountered the same problems we faced.
Junior System Administrator & DevOps at a tech services company with 11-50 employees
My interactions with HAProxy's customer support were limited, but the feedback from my team indicated satisfactory service.
Principal Engineer Manager at a manufacturing company with 501-1,000 employees
 

Scalability Issues

7.9
Users praise Cloudflare's scalability, flexibility, and seamless tier transitions for maintaining high performance under increasing traffic and demands.
Sentiment score
7.9
HAProxy efficiently handles scalability, easily adapting configurations for growing traffic, ideal for small to medium businesses and larger environments.
It is a SaaS tool, but the fact that they have workloads deployed across the world proves that it is a highly scalable tool.
Principal Cyber Prevent and Defense Engineer at a comms service provider with 1,001-5,000 employees
The tool offers very good performance, even during high-traffic periods.
Engineer at SITMEXICO
I rate the solution’s scalability an eight out of ten.
Independent Consultant at Unaikui
We manage an automatic load balancing feature where we add HAProxy servers dynamically behind the application load balancer to handle more traffic.
Head of DevOps at TripFactory
HAProxy's scalability is excellent; as our traffic expands, it handles load increases effortlessly.
Junior System Administrator & DevOps at a tech services company with 11-50 employees
For scalability, HAProxy meets my needs, supporting our initial horizontal scaling and then adapting to vertical scaling in a VMware environment.
Principal Engineer Manager at a manufacturing company with 501-1,000 employees
 

Stability Issues

Sentiment score
7.5
Cloudflare is generally stable and reliable, with some initial setup challenges but excellent performance and positive user feedback.
Sentiment score
8.1
HAProxy is reliable, handles heavy traffic efficiently, with minimal downtime, quick support, and frequent updates enhancing stability and performance.
I rate the solution’s stability an eight out of ten.
Independent Consultant at Unaikui
The service is very stable with no impacts during high-traffic periods.
Engineer at SITMEXICO
This reliability serves as a key reason for our choice, providing us with confidence even when faced with heavy traffic.
Junior System Administrator & DevOps at a tech services company with 11-50 employees
The hot reload feature of HAProxy also really helped us so that we never had to shut it down to reload it.
Co-Founder, CEO at a tech services company with 1-10 employees
We have reduced a lot of servers, replacing them with one or two HAProxy servers which deliver better performance, accuracy, and an almost 100% success rate with requests.
Head of DevOps at TripFactory
 

Room For Improvement

Cloudflare needs enhancements in speed, support, reliability, pricing, and documentation, while expanding integration, security, and analytics capabilities.
HAProxy needs a revamped GUI, improved APIs, better AWS integration, real-time config, enhanced docs, and stronger monitoring and security.
Despite these challenges, overall, Cloudflare remains the preferred solution compared to Azure, AWS CloudFront, and Google Cloud Armor.
Managed Services Manager at Adapture Technology Group
Customers do not have options to modify any configuration parameters in Cloudflare, whereas other competitor solutions, such as F5 Distributed Cloud, allow customers to tune configurations according to their requirements.
General Manager at bKash Limited
Areas like how assessment, discovery, and payload are dealt with and how it all comes into your organization can be considered when trying to make suggestions to Cloudflare for improvements.
Senior Cloud Solution Architect at Integrated Technology Solution Group (ITSG)
The configuration syntax is powerful yet can become overwhelming for newcomers; a more beginner-friendly interface or a native GUI without relying on third-party tools would ease the onboarding process.
Junior System Administrator & DevOps at a tech services company with 11-50 employees
An easier desktop interface to connect to a remote server and make changes on my PC would be beneficial.
DevOps engineer at a tech services company with 1-10 employees
The reloading functionality is effective as it allows soft reloads without interrupting traffic patterns.
Principal Engineer Manager at a manufacturing company with 501-1,000 employees
 

Setup Cost

Enterprise users find Cloudflare cost-effective, with valuable upgrades and competitive pricing, despite unclear enterprise price lists.
Enterprise users value HAProxy's competitive pricing and cost-effective licensing, especially compared to F5 and Citrix, despite initial setup costs.
I find it to be cheap.
Engineer at SITMEXICO
I rate the product’s pricing a five out of ten, where one is cheap, and ten is expensive.
Senior Solutions Architect at Think Power Solutions
The tool is a premium product, so it is very expensive.
Principal Cyber Prevent and Defense Engineer at a comms service provider with 1,001-5,000 employees
Since we use the open-source edition, there are no licensing fees, with the main cost being the infrastructure running on EC2 instances in AWS, which helps maintain low expenses.
Junior System Administrator & DevOps at a tech services company with 11-50 employees
Setting up HAProxy didn't cost anything for me.
DevOps engineer at a tech services company with 1-10 employees
The pricing remains competitive compared to other vendors.
Principal Engineer Manager at a manufacturing company with 501-1,000 employees
 

Valuable Features

Cloudflare provides caching, DDoS protection, and CDN services with enhanced security features, making it vital for optimized web performance.
Users praise HAProxy for reliable load balancing, customization, low latency, open-source benefits, and advanced features like secure traffic management.
The most valuable features of the solution are performance and security.
Senior Cloud Solution Architect at Integrated Technology Solution Group (ITSG)
Techniques like minification and image compression reduce the size of assets, leading to better performance and faster user load times.
Senior Solutions Architect at Think Power Solutions
The solution has been able to compare it to the market, and I think the product has taken great strides in automating quite a bit of things, and they use a lot of AI.
Principal Cyber Prevent and Defense Engineer at a comms service provider with 1,001-5,000 employees
By moving all SSL termination to the load balancer, I now manage certificates in a single place, and I can also utilize Let's Encrypt with HAProxy's built-in ACME support, making renewal automatic.
Junior System Administrator & DevOps at a tech services company with 11-50 employees
HAProxy positively impacted our organization by exceeding scalability expectations, initially projected at 200k requests but ultimately handling over 15 million transactions per second without any issues.
Principal Engineer Manager at a manufacturing company with 501-1,000 employees
As a production engineer at that time, I definitely wanted to ensure that the system could handle massive connections, especially since we operated an e-commerce platform where we could not lose any customer calls.
Co-Founder, CEO at a tech services company with 1-10 employees

General Manager at bKash Limited
Advanced protection has secured critical web workloads and provides clear traffic visibility
From a security perspective, there remains a security loophole, as some browsers in the market can bypass the Turnstile solution, which requires approximately 40 seconds to do so. From a performance perspective, this is acceptable. We also tried Google reCAPTCHA, and that can also be bypassed. From a security perspective, I would say neither solution is completely secured. Regarding uptime, we have faced a couple of incidents due to Cloudflare in recent years, so I cannot say we receive 100% uptime for our region. We sometimes face challenges, including downtime and other issues. As a result, we are not receiving 100% uptime from Cloudflare's solution. Since most of our customers are in this region, we need alternatives. We need something more competitive than Cloudflare. Unfortunately, in Bangladesh, Cloudflare has three points of presence already, and we cannot find any other solution provider in Bangladesh as an alternative, which presents another challenge. Competitor solutions have more attack signatures, which ensure better security compared to Cloudflare's predefined configurations. Customers do not have options to modify any configuration parameters in Cloudflare, whereas other competitor solutions, such as F5 Distributed Cloud, allow customers to tune configurations according to their requirements. Cloudflare could improve in this area. Additionally, regarding visibility, Cloudflare has static visibility, but they could adopt dynamic graph features for their customers.

Handles high traffic efficiently and simplifies complex routing with rule-based logic
I think HAProxy is good as it stands now, but I believe there could be improvements. gRPC has recently been implemented, which is great, along with TLS 1.2 and 1.3 support, and HTTP 2.0 is also available. However, I'm unsure about the benchmark of those HTTP 2.0 requests on HAProxy. If there were any other protocol with better performance than HTTP 2.0, or perhaps mTLS and other similar features, including that in HAProxy would be really great. For improvements, I think that during setup and configuration, the steps provided are neat and clear. Anyone can easily install and configure it. There are many kernel tuning parameters also available, which is great. For specific improvement, in terms of logging, I think printing the full object of the request may help, or if there's a way to reference two requests, it would be beneficial to find a complete session history from a logged-in customer, as it would help analyze customer and user analytics.
