Review summaries and opinions

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

ROI

Sentiment score
7.1
GeneXus offers high ROI for large companies, excels in banking apps, and is effective for both extensive and limited user systems.
Sentiment score
6.5
Mendix delivers high ROI through reduced development time and costs, quick deployment, and enhanced efficiency despite high license fees.
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.
SOFTWARE ENGINEER at Siemens Industry
I have seen a return on investment with Mendix, as in default software development, a team with 10 developers or more is needed, while here we can do it with one or two developers, so it is truly a money saver for the company.

Sentiment score
7.6
GeneXus customer service is fast, knowledgeable, cooperative, usually responding within 24 hours, and generally rated highly by users.
Sentiment score
7.0
Mendix support is praised for responsiveness, though improvements are needed in response times; partners receive prioritized assistance.
I haven't often needed to seek direct support from Mendix teams as their online resources and knowledge database are comprehensive.
Mendix Developer at Plieger
Mendix provides proper support, troubleshooting options, and a helping community.
Senior Software Engineer at a retailer with 5,001-10,000 employees
If it's about having an issue that I can't solve despite being a Mendix expert and having tried every single bit and piece, support can feel like a stone wall.
CTO at Blue Green Solutions
 

Scalability Issues

Sentiment score
8.4
GeneXus is scalable and adaptable, supporting growth from small projects to large systems with high ratings for ease and efficiency.
Sentiment score
7.0
Mendix is adaptable and scalable, but larger deployments may require expert modifications for optimal performance across different environments.
Mendix supports scaling well with its comprehensive online documentation and learning paths.
Mendix Developer at Plieger
Mendix provides options for handling scalability and maintainability through features like validation, workflow and nanoflow minimization, and user components, enabling projects to be easily managed and scaled.

Sentiment score

Room For Improvement

GeneXus requires better front-end, training, security, integration, collaboration, market awareness, UI, code speed, cost, community, alerts, performance, and language support.
Mendix requires enhancements in customization, UX/UI, integration, AI, scalability, pricing, IDE stability, learning, and database support.
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

GeneXus offers costly multi-plan licenses but justifies the price by replacing multiple developers and including maintenance and upgrades.
Mendix pricing is high and complex, suited for large enterprises with negotiable rates, but less ideal for startups.
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.

GeneXus offers rapid deployment, seamless tech integration, error detection, multi-language support, automation, and a user-friendly architecture.
Mendix excels in rapid app development with visual tools, ease of use, integration, security, and customization for scalability.

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.

Featured Reviews

Internal System Coordinator at Red CEDIA
Offers a simplified architecture with outstanding integration capabilities
The integration capabilities of GeneXus are highly valuable for our organization. The metadata obtained within the logic of different systems is also vital. Due to the solution, our company team doesn't have to work with multiple languages and integrations can be made with C Sharp. JavaScript can also be used with GeneXus, the tool takes charge of all the rest and has a simple architecture. The solution can be used out of the box without facing any issues and nothing much needs to be done with frameworks. In our case we need to use Python with GeneXus, we use Ironpython to embed python code in C# .
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.
