Builder.ai (discontinued) vs. OutSystems

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.

OutSystems excels with building web interfaces fast and lends itself to custom integrations written in .Net. Most anything can be brought in given this ability to be extended. One of the drawbacks to the speed of development is that most quality control teams become quickly overwhelmed and may be unable to keep up.

• Deployment management – OutSystems has a built in robust, multi-environment deployment system that helps ensures the clean and error free deployment of applications through the development, testing and production product lifecycle
• Rapid application development – Through the low code, graphical development environment you can develop applications far quicker than with more traditional development environments
• Cross platform mobile development – OutSystems handle the development and building of mobile application for both iOS and Android in a simple streamlined way that removes 90% of the problems normally associated with multi platform development

• The platform controls all the parts. While great for development and overall maintenance, it could lead to discussions with your DBA (who has to trust the platform). As a developer I love the platform, as a DBA I would like more control.
• By making software development model driven using flows, you are forced to rethink the way of programming. It makes it easier, but sometimes the way of working leads to code which could be optimized (standard problem in model based software development).
• Most of the code is generated, so the technical knowledge of the inner working of coding are not Essentials. This could lead to degration of this knowlegde. As part of this, most technologies will only be used when OutSystems supports it. They do a good job on implementing these things. But things like Node.js would be nice.

We are very happy with OutSystems and our developers deliver good work. OutSystems lets us build new software on a regulare (2 weekly) basis, which is highly flexible and adjustable. Even without very much experience, our developers manage to build usefull software, which is working a lot better than our previous (legacy) software.

See previous review

OutSystems has a feature in which we can develop a functionality in a application and can use that functionality in another application without developing it again. That is main plus point for the development team so they can work with different functionalities rather focusing on the same thing again and again. if we want to make any change on the user side then we can make it live with just the deployment using the service center.

The tech support is very reachable. Usually by [email] from but also by phone if needed. We had some difficulties at the start with understanding "what our machine was doing" under high performance load. After some good sessions understanding our needs they delivered good solutions for our problems we had in the beginning.

Excellent material full of hands on that improve the understanding of the platform.

The online training material is well designed and explanations are step by step, helping trainees to understand and follow each exercise and new concept.

In a large company, patiently and consistently work the behind the scenes politics with business and IT partners across the firm.
This is transformational - you will need a solid set of key business partners to lock arms together to move forward.

Totally different products of cource. Sitecore is best suited for full fledged websites with extensive support for analytics. OutSystems for modular business processes with a UI. Hence, there is no overlap. But even for small websites, or even landingpages, I would recommend OutSystems, with a custom made analytics part or a plugin.

• The ease of use of the OutSystems development process has been the biggest ROI for us. We have developed our Framework product and maintained/enhanced it with only 4 workers.
• OutSystems has enhanced their product very significantly over the last 4 years. They have gone from a simple to use tool to a very simple to use sophisticated tool that covers the standard mainframe-based computing apps and the apps used on handheld mobile devices all using the same basic set of development tools.
