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
6.2
Mendix reduces development time by 30%-40%, enhances efficiency, but high license fees may affect ROI despite growth potential.
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.
I see a fair return on investment using Mendix.
 

Customer Service

Sentiment score
7.6
GeneXus customer service is fast, knowledgeable, cooperative, usually responding within 24 hours, and generally rated highly by users.
Sentiment score
6.9
Mendix offers excellent support, with praised forums, valued resources, and varied response based on user plans and subscription.
I haven't often needed to seek direct support from Mendix teams as their online resources and knowledge database are comprehensive.
Mendix provides proper support, troubleshooting options, and a helping community.
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.
 

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
6.9
Mendix offers robust scalability and flexibility for diverse applications, effectively supporting small to large enterprise use cases.
Mendix supports scaling well with its comprehensive online documentation and learning paths.
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.
Also solutions processing data at scale, talking about one million packages a day.
 

Stability Issues

Sentiment score
8.1
GeneXus offers high stability with bi-monthly upgrades, rated 8-10 by users, best suited for simpler front-end applications.
Sentiment score
7.3
Mendix offers high stability with minimal issues, improved scalability, frequent updates, and strong performance, especially on stable versions.
Mendix has been stable in my experience, with reliable performance for enterprise applications and minimal downtime or critical issues.
I recently encountered an issue with deploying applications on the Mendix sandbox, which took a week to resolve.
 

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 needs better document templates, non-relational database support, legacy integration, licensing, UI/UX, reporting, AI, support, and scalability.
Access to the database is limited in Mendix's public cloud, preventing direct database interaction or inspection.
I choose a seven mainly due to the issues we've faced with slowdowns and bugs during development, while runtime has been very stable.
Native development is not very strong, and some developer tools are missing, such as shortcuts to edit multiple variables.
 

Setup Cost

GeneXus offers costly multi-plan licenses but justifies the price by replacing multiple developers and including maintenance and upgrades.
Mendix is seen as costly for small businesses, but it's cost-effective for enterprises with negotiable, transparent pricing.
The app license costs between $13,000 to $14,000, which is prohibitive for startups.
My experience with pricing, setup cost, and licensing is reasonable;
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

GeneXus offers rapid deployment, seamless tech integration, error detection, multi-language support, automation, and a user-friendly architecture.
Mendix enables rapid, low-code app development with visual modeling, seamless integration, and built-in security to enhance efficiency and reduce costs.
Mendix's integration capabilities are impressive, allowing for rapid and on-the-fly integration of almost anything imaginable.
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.
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

XavierEspinoza - PeerSpot reviewer
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
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.
