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
6.5
Mendix delivers high ROI through reduced development time and costs, quick deployment, and enhanced efficiency despite high license fees.
Sentiment score
6.6
OutSystems typically offers high ROI through fast development and cost savings, though initial expenses and developer skills impact outcomes.
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

Room For Improvement

Mendix requires enhancements in customization, UX/UI, integration, AI, scalability, pricing, IDE stability, learning, and database support.
OutSystems faces performance and integration issues, high licensing costs, and needs improvements in support, automation, UI, and documentation.
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.
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
It is crucial to be aware of which module corresponds to which application in real-time projects, as there are multiple applications.

Setup Cost

Mendix pricing is high and complex, suited for large enterprises with negotiable rates, but less ideal for startups.
OutSystems is costly, suited for larger enterprises, with yearly fees varying by usage, covering licenses and infrastructure.
The app license costs between $13,000 to $14,000, which is prohibitive for startups.

Featured Reviews

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.

OutSystems facilitates rapid application development and effective project management
What I find valuable about OutSystems is that it has a very good learning curve for developers. Within two weeks, we can gain knowledge in OutSystems, and it is very easy to learn. With my background being .NET, OutSystems is straightforward to learn, which is beneficial. Developing applications in OutSystems is good, and the flexibility allowed by OutSystems for application development is excellent compared to my experiences with other low-code technologies, where I've faced some challenges. The clean separation of concerns in the architecture provided by OutSystems is a key benefit compared to other platforms. OutSystems integrates with our existing tech infrastructure and provides flexible integration. If we want to integrate with third-party services, OutSystems has SOAP and RESTful services that allow us to consume external services, integrate with external databases such as SQL or Oracle, and includes integration studio for writing custom .NET code. After developing a .NET component, we can reference it in service studio, creating a reference file that makes integration easy. OutSystems officially supports various integrations and also includes an API discovery tool for consuming and exposing services, providing a lot of information about incoming URLs, similar to how we use Postman.

Mendix can be improved in that, while it is good at pricing, it lacks a small business budget project for startups wanting to build their portfolio. The company can improve in that perspective, and...
