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.

Room For Improvement

GeneXus requires better front-end, training, security, integration, collaboration, market awareness, UI, code speed, cost, community, alerts, performance, and language support.
Users seek better templates, UX/UI, integration, reporting, scalability, AI, and support, criticizing complexity and documentation.
Overall, Mendix platform is stable, but the IDE could be better.
Native development is not very strong, and some developer tools are missing, such as shortcuts to edit multiple variables.
Access to the database is limited in Mendix's public cloud, preventing direct database interaction or inspection.
 

Setup Cost

GeneXus offers costly multi-plan licenses but justifies the price by replacing multiple developers and including maintenance and upgrades.
Mendix is pricier but reduces development time; ideal for large enterprises, region-specific pricing can be negotiated.
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;
 

Valuable Features

GeneXus offers rapid deployment, seamless tech integration, error detection, multi-language support, automation, and a user-friendly architecture.
Mendix offers rapid app development with low-code capabilities, visual interface, system integrations, Agile support, and robust scalability.
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.
The solution is beneficial for integration with existing systems due to features like AI integration, SOAP integration, REST API integration, and various other options.

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.
