Illa – An open-source alternative to Retool
Hey HNs: This is Vincent from the ILLA team. I'm sure you guys see tons of "Open-source" and "Alternative to Retool" these days. I won't deny Retool is a great product, and so are many open-source competitors such as Appsmith, Budibase, Tooljet etc. However, what makes ILLA so special? What advantages does ILLA have that allow users to choose ILLA instead of others? Well, I would like to answer those questions to all folks at HN one by one. First, we are similar to Retool, or Appsmith but we have many different our own features. We are a true open-source project all the folks here can check…
In plain words
ILLA is an open-source platform for building internal tools and applications, positioning itself as an alternative to Retool. It provides a development environment where users can create custom applications with visual builders and code components. The platform is fully open-source, allowing developers to review and modify the codebase. ILLA targets developers and teams who need to build internal tools while maintaining control over their infrastructure and source code.

Hey HNs: This is Vincent from the ILLA team. I'm sure you guys see tons of "Open-source" and "Alternative to Retool" these days. I won't deny Retool is a great product, and so are many open-source competitors such as Appsmith, Budibase, Tooljet etc. However, what makes ILLA so special? What advantages does ILLA have that allow users to choose ILLA instead of others? Well, I would like to answer those questions to all folks at HN one by one. First, we are similar to Retool, or Appsmith but we have many different our own features. We are a true open-source project all the folks here can check and review our Code here: https://github.com/illacloud/illa-builder. We believe as developers the basic ethic is to be honest, especially in "open-source" circumstances. You have to be honest with your team, users, and contributors in order to grow. Therefore, we welcome all the contributors from around the world to build ILLA together, this is a promising project and won't let you down. With your code, we can build the next DevTool together instead of just making some cash. Ok, so maybe some folks here would say that I don't care about "Code Integrity", and there are many different options such as Appsmith, Budibase, and Tooljet. Why should I use ILLA here? Well, we believe the difference between animals and homo sapiens is that people know to use tools to improve their work efficiencies. Our whole team members are developer backgrounds and we know many itch issues we would like to solve for developers. So maybe our newest 1.3.3 version is not good enough, but just give us a little more time and I'm you will see the differences. In the end, We are also "open-source" first. We are willing to collaborate with different open-source alternatives as much as we can. For example, we just partnered with PingCAP a few weeks ago. We will support many other open-source databases such as MindsDB, Supabase, etc soon. We can also support many other open-source alternatives, if you are interested, you can always find us in our Discord community. Our Repo again: https://github.com/illacloud/illa-builder

I made a thing! In 2014, I was holding a stack of iPhones and thought to myself: "Hey, if I had each phone display a playing card, I could click a button and they'd shuffle themselves" I pared that idea all the way down to this: trading cards made of e-ink displays. Right now, each card costs me about $20 each, but with only a bit more scale, I think I can get that down to $10. In doing this project, I learned how to design electronics and circuit boards. I learned Rust and wrote my first driver, I upped my CAD skills, 3D printed, and did my first resin casting. I generated the images on the…
