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

ROI

Sentiment score
6.3
Fireworks AI boosts efficiency by reducing task time and costs, enhancing performance, and accelerating time to market by six months.
Sentiment score
6.4
Mendix's low-code platform accelerates development, reduces costs, and enhances productivity, offering significant ROI and efficiency over traditional methods.
Time to market has been accelerated by six months.
Co-Founder and CEO at Seismora
We do not have to worry about engineering effort, leading to a twenty to thirty percent reduction in the engineering time for data engineers working on infrastructure.
Product Manager at a tech vendor with 11-50 employees
Fireworks AI has saved my team around half of what we used to take because initially, we had to manually research all the models.
full stack developer intern at a tech services company with 1-10 employees
Traditional applications tend to have larger sizes and higher deployment costs, whereas with Mendix, the time of delivering applications, manageability, and smaller team sizes are significantly lower.
Senior Software Developer at RapidData
It's not that they're really firing that personnel, but they can often focus on the core that really matters instead of repetitive processes in Excel forms and all of the overhead and human error that comes with that.
CTO at Blue Green Solutions
Since Mendix is a low-code platform, the ROI is significant; we save a lot of money and require fewer people to do an application, reduced to two, which drastically decreases development time because this is not traditional programming; just drag and drop, and we can complete projects that would take years within months.

Room For Improvement

Fireworks AI requires better documentation, debugging, cost transparency, integrations, and user-friendly improvements to enhance flexibility and reduce expenses.
Mendix needs improved integration, documentation, design, language support, pricing, stability, native mobile development, and easier automated testing.
Fireworks AI is based on tool calling, so I think it needs to add more other kinds of connections to enable faster data retention and optimization.
Ai스페셜리스트매니저 at a tech vendor with 501-1,000 employees
I think it has zero video generation capabilities, making it really hard for someone wanting to make a visual AI project.
full stack developer intern at a tech services company with 1-10 employees
A product sold as 'pay-as-you-go' should never produce a surprise $40,000 charge with no spending cap, no real-time threshold alert, and no notification.
Principal Software Engineer at a consultancy with 1-10 employees
Access to the database is limited in Mendix's public cloud, preventing direct database interaction or inspection.
Mendix developer at a tech vendor with 10,001+ employees
I choose a seven mainly due to the issues we've faced with slowdowns and bugs during development, while runtime has been very stable.
CTO at Blue Green Solutions
Native development is not very strong, and some developer tools are missing, such as shortcuts to edit multiple variables.
Software Development Intern at a educational organization with 1,001-5,000 employees
 

Setup Cost

Mendix's pricing is steep for smaller businesses, though it offers flexibility and efficiency for large enterprises.
We received a sudden $40,000 charge via AWS Marketplace, which we obviously never used, and we filed a case for it.
Principal Software Engineer at a consultancy with 1-10 employees
The app license costs between $13,000 to $14,000, which is prohibitive for startups.
Mendix developer at a tech vendor with 10,001+ employees
My experience with pricing, setup cost, and licensing is reasonable;
CTO at Blue Green Solutions
From the pricing shown on the Mendix webpage, we have a basic package where you pay 60 Euros a month for five users and 10 Euros per additional user.

Valuable Features

Fireworks AI enhances AI deployment with rapid speed, cost efficiency, seamless integration, and extensive customization, boosting performance and development.
Mendix provides rapid development with low-code tools, model-driven architecture, and integration, enhancing collaboration, scalability, and efficient deployment.
It follows standard OpenAI-compatible endpoints, which meant we could swap out models or integrate new ones without rewriting our entire service layer.
FullStack Developer at EnactOn Technologies
After introducing Fireworks AI's high-speed inference engine, I found that communication speed between agents was about twice as fast as before.
Ai스페셜리스트매니저 at a tech vendor with 501-1,000 employees
Having access to multiple model tiers helps our team balance quality and cost by giving us leverage where we can make options and look at what best suits our company and what we could use, which is beneficial because when you have multiple choices, you can tailor your approach and get what you actually need, so our options are not limited.
Assistant Banking Officer at Zenith-bank
Mendix's integration capabilities are impressive, allowing for rapid and on-the-fly integration of almost anything imaginable.
Mendix developer at a tech vendor with 10,001+ employees
The best features that Mendix offers are proper guardrails that prevent starting from scratch, ensuring a certain level of security, user experience, and standardization for implementing workflows, API integrations, and how you set up your domain model.
CTO at Blue Green Solutions
For security, I value the built-in authentication, role-based access control, and data protection features, which make enterprise apps safer without needing heavy custom setup.

Automation has accelerated agent workflows and now needs broader connections for enterprise data
In the current function calling, if Fireworks AI could be added as part of our RAG system not only with the function calling we are using now but also with a variety of other connections, then an even better situation would be possible. Fireworks is based on tool calling, so it needs to add more different kinds of connections to enable faster data retention and optimization. Although multiple optimal optimization or measurement methodologies for using LLMs are being discussed, when using them inside enterprises, the main thing is actually measuring work handling capability or work processing speed. Based on that, and also through what might be called interviews with business-side staff, we measured the speed improvements in a somewhat indirect manner.
Mitchel Mol BGS - PeerSpot reviewer
CTO at Blue Green Solutions
Has improved development quality and speed but has introduced persistent IDE slowdowns
In recent years, the IDE has been more buggy and slower, and although there have been more features added, I would like to see more stability, as some areas that used to work for a fairly long time are now slower in my development, which feels like a step back. I choose a seven mainly due to the issues we've faced with slowdowns and bugs during development, while runtime has been very stable, and the overall output on Mendix platform is still good; there is definitely some room for improvement, and I would probably have given it an eight or even a nine if those issues weren't hurting my developer output for the past few years. Overall, Mendix platform is stable, but the IDE could be better.
