    TLDR: 28 months into a 6 month project. They stopped developing it without a working MVP, fired all the developers, and do not respond to my requests that involve figuring out what’s happening and when I will be getting a refund.First, please feel free to reach out before removing this review. Builder.ai has taken down our bad reviews in the past saying they couldn’t verify them. I’ll be happy to point you in the direction of the people I’ve worked with including Jason.Second, when I say this is a fraud from the top down, I’m not exaggerating. Please take a look at the news articles that have come out within the last two years regarding their CEO, CFO, and official auditor.If you are still reading, that means you’re still considering it, so let me tell you about my experience.I started this process by meeting with the sales team at the Silicon Slopes Conference in late 2022. I told them about what I wanted to build and they said that would be very easy and doable. We spent the rest of 2022 meeting with developers who reconfirmed how simple this would be and that even with a relaxed timeframe, we could expect a product in about six months. January 2, 2023, I signed the contract.We had a number of problems from the very beginning, including them giving me the wrong documents to sign and mixing my product up with another. We kept meeting, moving forward, struggled constantly with getting the money flow correct. Weeks turned into months and eventually all of the deadlines were past due with no communication on when they would get updated. Near the end of 2023, we escalated and very clearly said that if they cannot develop this, it’s OK to just say as much and give us our money back. They repeated that they could, added additional developers to the team, and said they would be pushing forward with an MVP shortly.When they released the MVP, the flow of money still didn’t work. Whenever I would bring that up or that I wanted to do end to end testing, they would say that they will be able to do that when it’s ready for full release. Again, months passed of this and I stayed patient. I have to say my patience has been the biggest mistake of this entire process.In November 2024, 23 months in on a six month project, they marked it complete. It wasn’t. The money was still wrong, features I had previously approved had vanished, and when I asked why features I paid for weren’t on there, they said they had questions but decided not to ask them and just mark it complete instead. I was furious, but once again I was trying to make it work. I worked with my project manager, and we spent December creating an entire list of every acceptance criteria. I required photo or video evidence for each piece that it was complete or I wasn’t going to mark it done. I also told them they had until the end of March.As we moved through January and February 2025, they started slipping in comments about how they didn’t think we would make the deadline. I continued escalating, people tried to work with me on it, and I decided to once again, find my patience. It did me no good.On March 26, my project manager told me that they were no longer working on developing my project. They had fired everyone who would’ve been part of developing it and had no plans on what to do going forward. They were supposed to tell me the week before when it happened and he expected that I should get an email about it that week. When I tried reaching out to the legal team that same week about canceling any sort of ongoing contract and getting my money back, they told me they were going to refer me to another group. It is April 18, 2025 and still I have received no communication. My patience now means that I have signed myself up for a painful legal battle. I’m leaving this review to let others know that if they already have a contract, chances are no development work has happened for the last month and they need to demand answers. This is also here for people considering this company. Do not fall for it.

    Mendix excels in scenarios involving Business Process Automation, making it a strong choice for applications requiring workflow automation, including processes like request approvals, document management, and other business workflows.Conversely, Mendix may be less suitable for projects that demand highly customized solutions with extensive custom coding. Its primary focus on low-code development may not align well with the requirements of projects that heavily rely on intricate and specialized coding.

    • We're able to really easily develop different views that are very specific to a customer's needs or customer's different types of user needs. So for example, the production managers can have a certain view that's relevant to them and then certain line managers can have views that are specific to them that allow them to run different scenarios which they define. So it allows us to easily build customized apps for each different type of user.

    • Earlier versions lacked in UI/Ux. This is still improving.
    • Since everyone and anyone can create custom add ons (widgets), Mendix could improve their quality checks (but not as rigid as eg Apple).
    • Upgradeability used to be somewhat of an issue. Version 7 looks to be handling this better than previous versions.

    A 10 would say I have nothing to wish for. A 9 means I haven't seen anything better.This tool really helps you in the whole creation and maintenace cycle, so from requirements to building/modeling to testing to deploying to capturing feedback.

    Response times are quick and you will get updates regularly about the status of your request. Even with very technical questions they have specialists that can help you with your problems it will give you an answer or help you with a work around.

    Mendix would be my preferred system all the way. The system is designed for these kinds of works. I've worked with WP and DNN but they should be used just for websites. To create an app for a business value, I would suggest Mendix. Also, the offline capabilities of Mendix have greatly improved since the deployment of Mendix 7.13.

    • It helps to speed up application development because of its low code by the fact that it's low code. It allows professional developers to focus more on specialized application development rather than the more routine application development that business IT and super users can do for themselves with some coaching from the IT department. So it's just allowing the more specialist professional developers.net, for example, Java in our organization to focus on more complex engineering application developments.
