Builder.ai (discontinued) vs. Zeplin

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.

I still have some issues, especially with color integration between the style guide and also project. When we update the colors, it's not automatically sync to every project. Aside from that, zeplin solves my problem for hand-off design from design to developer. I set zeplin is source of truth design file

• Provides dimensions across iOS, Android and Web which saves developers from a lot of guess and check when implementing designs
• Allows for easy download of digital design assets for developers to easily organize and implement
• Great user experience in terms of the product itself and a great value for your money
• Automatically generates CSS for web designs which is AMAZING!

• It would be better if it has a dedicated web application
• It's not the easiest tool to learn and start working with
• It would be awesome if it had more features turning it into an all-around tool for mockups and prototypes

Zeplin's component management and style guide help us to be consistent across whole product and it so easy to use for non-technical person. It is now easy to collaboration for designes between different teams like stackholders, product owner, UI/UX, developers and testers. Now there is only one point of reference is Zeplin so it is so easy to get details without asking designer or developer again and again.

Zeplin has classic support with a chat from the website. It's working fine, and we're also getting the support needed when needed. However, Zeplin is very good at closing the incidents and moving on. It was a while ago we had a case with their support so that it might have improved since then.

Out of all of the products that I have used to support design-to-development handoffs, Zeplin is my favorite. It’s pretty lightweight and easy to use (once you get the hang of it). Zeplin also has a smooth interface and is, generally, clearer to use than other tools, such as InVision. Plus, all of the plug-ins that you can use with Zeplin have supported the design-development relationship and workflows in which I’ve been involved in more efficient, clear, and effective ways than I’ve seen with any other product.

Incentivized

• We're using the free plan, so it fits in our needs, although we're limited to create only one project at a time
• Sketch has some plugins that offers exactly what Zeplin does, for free
• The integration with design apps (Sketch, Photoshop, XD) and collaboration (Slack and Trello) helps our team to better communicate and be notified on every update
