Builder.ai (discontinued) vs. Syncfusion® Essential Studio®

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.

The datagrid is probably their most popular control I would think. It is so flexible and configurable. Most of mine are plain views in ASP.NET Core, but I have a whole bunch that are dynamically created at runtime in my controller. That is so powerful.

• Integrates well into Microsoft tech stack. i.e. ASP.NET, Blazor etc. So it acts as a plug-n-play, which is great!
• Shrinks the development cycle without adding too much of its own ecosystem overhead.
• Provides different UI skins so the controls don't appear as "stitched".

• Sometimes links point to dead addresses in the documentation.
• Some components have a difficult learning curve but that is usually due to the complexity of the control.
• Minor version changes introduce breaking changes, for example updating from 20.1.x to 20.2.x gives us licensing errors, which in my opinion is a kind of breaking change as it requires all users to update their licenses.
• Theming with CSS variables is not possible. Access to Theme Studio code is not possible. So a fully custom solution is needed to make Syncfusion Essential Studio Enterprise Edition components themeable with CSS variables.

It takes effort to include a new component library into existing software, especially in our case where we have 5 large applications that are written and maintained by about 100 developers. So changing such a core thing comes with a lot of effort. The other reason we will very likely renew our use of Syncfusion Essential Studio Enterprise Edition is that it works really well and has helped us to speed up the development process.

See previous review

I would rate Syncfusion® Essential Studio® a 10 out of 10 for overall usability. The components are intuitive to implement, with clear APIs and consistent design patterns across the suite. This makes it easy for developers to get started quickly and reduces the learning curve even when working with new controls.
In addition, the documentation and sample projects provide practical guidance that helps accelerate development. The built-in customization options also allow us to adapt the components to fit our branding and business requirements without excessive effort. Overall, the usability is one of the key reasons why Syncfusion has become an essential part of our development toolset.

Although I have decades of software development experience, I had never created a website from scratch before, and my html and css skills are not particularly strong. Between documentation and incredible dedication from the support team they helped me overcome all of my challenges. It's amazing that they typically create sample code for most of the issues that I submitted. On rare occasions where I uncovered a defect they kept me informed as to its status, and typically resolved it in a short-term release, and/or gave me a reasonable workaround. They hopped on zoom calls with me on multiple occasions when necessary.

Feedback from the team has been very positive.

Firstly, there is a free version for small businesses and it allows you to jump start without risk. I found one of the other products a bit short in the number of out-of-the-box supported events handlers for each control and, although you can manually add them, I feel more comfortable to just have them ready. After using the free version I just felt in love with Syncfusion Essential Studio Enterprise Edition controls and decided to stay with them; they have all I need and more. The usage of Syncfusion Essential Studio Enterprise Edition controls is straightforward and intuitive. Support is world-class even for the free version; you get answers in 24 hours at most. Also, the support team is ready to remotely connect to your project in case it is needed; we have had one situation like this, and the issue was solved.

• First of all, I think the best positive impact is the reduce of time development. I do not know exactly how much time, but certainly, using the framework we save a lot of effort and time.
• About negative impact, sometimes using the controls of the framewrok have a signifcant impact in the execution time and page load.
• And of course, the use of Syncfusion Essential Studio Enterprise Edition has a significant impact of the learning of javascript and JQUERY.
