Comparison Buyer's Guide

Executive Summary

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
6.7
Google Firebase is cost-effective for large apps, with valuable features and manageable for small teams, despite some expenses.
Sentiment score
6.5
Mendix offers cost savings and quick app development but substantial fees may affect overall investment returns for some users.
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
7.1
Users rarely need support due to excellent documentation and community resources, but views on direct support vary.
Sentiment score
7.0
Mendix support is responsive and helpful, with efficient issue resolution and valuable online resources, though non-pay users may face challenges.

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
6.8
Firebase is scalable and flexible, though some users face challenges with pricing and configuration as usage increases.
Sentiment score
7.0
Mendix offers smooth scalability and flexibility but may face challenges with larger user numbers and public cloud environments.
It can handle all tiers of the market effectively.
DIV head at a tech services company with 201-500 employees
Google also has some other cloud services, but when we compare Google Firebase, it is not as scalable.
Chief Technical Advisor at a tech services company with 1-10 employees
I would rate the scalability of Google Firebase as eight because I miss some features from MS SQL, particularly the SQL functions.
IT specialist at CUADRO OCHO INC
Mendix supports scaling well with its comprehensive online documentation and learning paths.
Mendix Developer at Plieger
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.

8.0
Google Firebase is praised for its stability and reliability, with minor concerns about downtime and performance by some users.
Sentiment score
7.4
Mendix offers stable performance with effective support, though large deployments may face challenges; stable versions are recommended.

Room For Improvement

Users want improved control, logging, queries, pricing, support, interface, documentation, and integration for better Cloud Function performance.
Mendix needs better UI, reporting, integration, pricing clarity, AI features, and improved stability, documentation, and training resources.
Since Google Firebase is a NoSQL platform, areas for improvement include enhancing query functionalities to be more equivalent to SQL, like MS SQL.
IT specialist at CUADRO OCHO INC
Automation testing with mobile devices could be improved, especially in regression testing to ensure that new feature launches do not affect other features.
DIV head at a tech services company with 201-500 employees
Access to the database is limited in Mendix's public cloud, preventing direct database interaction or inspection.
Mendix developer at a tech vendor with 10,001+ employees
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
 

Setup Cost

Google Firebase offers a free tier and scalable pricing, but users should carefully manage costs due to potential fluctuations.
Mendix pricing is high for small businesses but offers transparency and potential discounts for large enterprises and long-term commitments.
They could have implemented credits based on usage so that users would be able to easily calculate the pricing and provide it to customers.
Chief Technical Advisor at a tech services company with 1-10 employees
Google Firebase offers a reasonable pricing structure.
DIV head at a tech services company with 201-500 employees
The app license costs between $13,000 to $14,000, which is prohibitive for startups.
Mendix developer at a tech vendor with 10,001+ employees
My experience with pricing, setup cost, and licensing is reasonable;
CTO at Blue Green Solutions
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

Firebase excels with real-time database, authentication, cloud functions, push notifications, and scalability, ideal for rapid app development.
Mendix excels in rapid app development with low-code tools, strong integration, security, and collaborative features for agile businesses.
What I appreciate most about Google Firebase is the speed, accuracy, and security it offers.
IT specialist at CUADRO OCHO INC
It allows for pre-launch testing without publishing it on Google Play right away.
DIV head at a tech services company with 201-500 employees
A real-time database.
Chief Technical Advisor at a tech services company with 1-10 employees
Mendix's integration capabilities are impressive, allowing for rapid and on-the-fly integration of almost anything imaginable.
Mendix developer at a tech vendor with 10,001+ employees
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.
CTO at Blue Green Solutions
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.

Leverage rapid prototype development for application building
The pricing structure needs improvement since it uses cloud billing. We do not know how the pricing is calculated as it is all on the cloud. The concept that the more you use, the more you have to pay could have been much better. They could have implemented credits based on usage so that users would be able to easily calculate the pricing and provide it to customers. I am the co-founder and CTO of the company called Aiwox (A I W O O X). We have numerous projects for mobile application development, and we have shifted from Google Firebase to Supabase because there is a fixed price for Supabase. Supabase is built on top of AWS, and it provides a very good pricing model. Some of the credits are free, and once you reach a certain limit, you know the charges. The second improvement area is related to SQL. They provide the real-time database, which is very good, and they have gradually started including PostgreSQL, which is a relational database, but it is not production-ready yet. I may be incorrect; perhaps they have released something new, but PostgreSQL database real-time database remains a challenge with Google Firebase.
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.
