Base44

Base44 is an AI application builder focused on business use cases. Where many AI builders start from the website side and extend into apps, Base44 starts from business logic: what does this tool need to do, who uses it, and how does data flow through it?

What it builds

Base44 is designed for custom business applications: internal tools your team uses, dashboards for tracking business metrics, client-facing portals, custom workflow tools. If you have ever thought "I wish we had software that did exactly this specific thing for our business," Base44 is the right place to start.

Who it is for

Base44 works best for business owners who have a clear picture of a process they want to systematise. A cleaning company that wants a job scheduling tool. An estate agent who wants a custom client tracker. A consultant who wants a bespoke project management tool that fits exactly how they work.

If you can describe the process step by step, Base44 can often build the tool to support it.

How it compares

Compared to Lovable, Base44 leans more heavily into the business tool use case. Both are capable, and it is worth trying both for complex applications to see which produces the better result for your specific need.

For standard websites, Bolt is a better fit. Base44 is for when you need something functional and custom.

Getting started

Visit base44.com, describe the tool you want to build, and work through the conversation to refine it. Start simple and add complexity once the core is working. A working prototype that does 80% of what you need is far more valuable than a spec that does 100%.
