ROI

Sentiment score

Mendix's free version and automation enhance efficiency, reduce costs, and support growth, despite high license fees impacting returns.
Sentiment score
6.6
OutSystems typically offers high ROI through fast development and cost savings, though initial expenses and developer skills impact outcomes.
Sentiment score
7.8
Organizations using Temenos Quantum report increased development efficiency, cost savings, improved security, seamless integration, and scalable architecture benefits.
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.
Developing that same project in OutSystems can be completed in around 40 to 50% less time, requiring only six resources.
 

Customer Service

Sentiment score
6.8
Mendix offers comprehensive resources and active community support but experiences mixed reviews on response times and portal improvements.
Sentiment score
7.0
OutSystems' service is generally proactive and responsive, but advanced help varies by SLA, location, and contract tier.
Sentiment score
5.7
Temenos Quantum's support is generally helpful with a good ticketing system, but response times and experiences vary.
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.
Many helpful videos and documentation are available on the OutSystems site, making it relatively easy to learn the platform.

Sentiment score
7.5
OutSystems offers scalable, adaptable solutions for enterprises, with seamless cloud expansion and efficient management, despite pricing concerns.
Sentiment score
7.0
Temenos Quantum is praised for scalability and performance, supporting 100-1000 users, despite some complexity concerns compared to Flutter or React.
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.
They can be deployed vertically and horizontally, supporting as many deployments as needed.
 

Stability Issues

Sentiment score
7.3
Mendix is highly stable with minor performance issues, reliable architecture, effective support, and high user satisfaction post-Siemens investment.
Sentiment score
7.8
OutSystems is praised for stability and reliability, handling large systems well, with minor issues on high data loads.
Sentiment score
7.5
Temenos Quantum is stable and reliable with frequent updates, but areas like pending applications and front-end need improvement.
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

Users seek enhancements in Mendix's templates, integration, UX, databases, reporting, pricing, version control, AI, support, and customization.
OutSystems faces performance and integration issues, high licensing costs, and needs improvements in support, automation, UI, and documentation.
Temenos Quantum requires security, interface, and stability enhancements, better integration, faster support, flexible widgets, and improved development tools.
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.
It is crucial to be aware of which module corresponds to which application in real-time projects, as there are multiple applications.
I would like to see more integration between the use of artificial intelligence to speed up the process delivery time.
What I would like to see is more servicing business analysts in the next release of OutSystems.
 

Setup Cost

Mendix is costly but efficient, suitable for large enterprises with budgets, yet less accessible to startups.
OutSystems is costly, suited for larger enterprises, with yearly fees varying by usage, covering licenses and infrastructure.
Temenos Quantum is costly, with prices ranging from $70,000 to $500,000, though some users find it affordable.
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;
Subsequent users can be added at an additional cost per user; exact pricing details can be found on the OutSystems site.
 

Valuable Features

Mendix offers rapid, low-code development with seamless integrations and agile support for secure, scalable enterprise and mobile applications.
OutSystems streamlines development with low-code tools, offering rapid deployment, easy integration, and enhanced productivity through reusable components.
Temenos Quantum is valued for its user-friendliness, customizability, integration, security, and comprehensive mobile and web development features.
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.
OutSystems offers a lot of reusable components and solutions that I can simply drag and drop and use, which has a significant impact on project delivery time.
OutSystems has a very good learning curve for developers.
I have recommended it in situations where very rigid enterprise structures are blocking them from being agile.

Featured Reviews

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.
Sukrut Joshi - PeerSpot reviewer
Enables users to develop applications quickly and has a responsive and helpful technical support team
The time to market is quite good. We can quickly develop an application using the tool. OutSystems is developed using .NET and Java. We can easily find technical resources who have worked on .NET and Java and leverage their previous knowledge to develop OutSystems applications. It can also be used for application development. If an end-user does not want to use the solution after two to three years, OutSystems sends the source code and the applications to the end-user. There is no dependency. It’s one of the major factors I found quite good in OutSystems.
Saad Zia Soomro - PeerSpot reviewer
Enhancing banking with robust security but lacking in comprehensive support
When it comes to their support team, my experience hasn't been particularly positive. We've had numerous interactions with them, and a lot of issues have arisen during these encounters. Most of the time, the support team has been unable to provide guidance or in-depth knowledge about their own product and it seems that the development team, the core team, understands the product far better than the support team.
