Top 7 low-code tools that can compete with Stacker

To turn your idea into life, you need to develop your app backbone first. Software development requires using code. Well, it used to. Now, you don’t necessarily have to spend time on hand-coding from scratch to create business logic, build an interface, etc. 

With the use of a low-code internal tool builder, you can assemble your app from the pre-made templates and building blocks. You can further connect your database to it, share the app with your team, investors, stakeholders.

With modern low-code platforms like Stacker, Retool, UI Bakery, you can build almost anything – from CRUD apps to complex internal tools and web applications.
