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
7.2
Boomi AtomSphere Flow streamlines processes, reduces errors, improves productivity, and enhances integration, automation, data visibility, and decision-making.
Sentiment score
6.6
Mendix's free version and automation enhance efficiency, reduce costs, and support growth, despite high license fees impacting returns.
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
6.5
Boomi AtomSphere Flow support is effective but inconsistent, with strong documentation aiding users in resolving issues independently.
Sentiment score
6.8
Mendix offers comprehensive resources and active community support but experiences mixed reviews on response times and portal improvements.
It lacks clarity on how to reach out, write emails, or understand responsiveness.
I have not personally dealt with Boomi's customer support, but my team mentions that support is not good.
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
7.5
Boomi AtomSphere Flow is effective and rated highly for scalability but requires manual adjustments for resource scaling.
Sentiment score
6.9
Mendix efficiently scales horizontally and vertically, offering flexible solutions for private cloud users despite some public cloud limitations.
I would rate the scalability as nine out of ten, as it effectively scales to meet our clients’ needs.
In terms of scalability, the tool is quite scalable, and I would rate it eight or nine.
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
7.3
Boomi AtomSphere Flow is stable and efficient for moderate use but struggles with heavy data loads and API integration bugs.
Sentiment score
7.3
Mendix is highly stable with minor performance issues, reliable architecture, effective support, and high user satisfaction post-Siemens investment.
The solution maintains high stability, which makes it reliable.
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

Boomi AtomSphere Flow needs user-friendliness, stability, AI enhancements, better support, and flexibility for complex integrations and large datasets.
Users seek enhancements in Mendix's templates, integration, UX, databases, reporting, pricing, version control, AI, support, and customization.
We are particularly interested in exploring AI features more thoroughly, focusing on next-generation enhancements like ChatGPT.
For complex integration scenarios, Boomi could improve its flexibility.
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

Boomi AtomSphere Flow's pricing is seen as reasonable, especially for small-scale operations, with ratings averaging 6.5-7/10.
Mendix is costly but efficient, suitable for large enterprises with budgets, yet less accessible to startups.
The pricing is considered a bit expensive yet not excessively so, particularly when compared to similar solutions like MuleSoft.
The pricing is good for a small-scale company like ours, and the licensing cost is reasonable.
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

Boomi AtomSphere Flow streamlines integration with a low-code interface, boosting scalability, security, and efficiency across diverse systems.
Mendix offers rapid, low-code development with seamless integrations and agile support for secure, scalable enterprise and mobile applications.
We use Boomi for various types of integrations, such as SFTP integration, database integration, Snowflake integration, and we also perform transformations using maps and scripts.
The most valuable features include the ease of designing Boomi flows and the significant cost savings and reduced time to market they offer our clients.
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.

A tool that helps save money in the long run with a need to offer users the ability to deal with large datasets
From an improvement perspective, Boomi AtomSphere Flow should come up with the ability to deal with large datasets. The data integration part is a concern when you try to connect to an on-premises environment since the latency is high, making it an aspect where improvements are required to reduce the latency. Whenever Boomi AtomSphere Flow gets integrated with applications like SAP, it is important to ensure that what you develop is user-friendly, which is a process that takes time, especially when compared with webMethods.io or TIBCO. The development effort with Boomi AtomSphere Flow is more when you compare it with other tools, which is a drawback and an area of improvement.
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.
