Best Fluidspace (beta) Alternatives - 2025

ToolJet is an open-source low-code framework to build and deploy internal tools and business applications. ToolJet is an open-source alternative to Retool, Mendix, Microsoft Power Apps and Outsystems.

ToolJet is a game-changer for anyone trying to get into web app development or prototyping! I was amazed by how simple it was to use. Even with limited experience with similar softwares, I could quickly build prototypes that felt super complex at first. It’s intuitive, beginner-friendly, and honestly just fun to work with. What I love most is how approachable the community is—they’re always ready to help, no matter how basic or tricky your question is. It’s like having a team of supportive friends who genuinely want you to succeed.

Amazing app! Easy to build, flexible and powerful! (I use it with an Airtable base, and syncs perfectly)

Build & customize your internal tool or a business app. Connect datasources, integrate with third-party APIs, add business logic, share your app securely.

I originally started with 3 Low-Code Solutions for our application: 1) Retool 2) Appsmith 3) UI.Bakery Myself personally, I created the application in literally all 3 before choosing my favorite. Reasons for my selection: 1) Price...clear and simple...no price per user, no price per database call, etc...the competitors are VERY quick to hide these details. 2) UI...we presented our demo to quite a few people, and UI Bakery stood out as the clear winner 3) Customer Support...I have never quite met a company that is SO engaged. The chat window is INSTANT. Meeting requests are very fast and often the next day 4) This tool can be used for simple applications or complicated ones (such as mine with heavy Javascript coding). It really covers it all.
