Top 5 open-source form builders

Online forms are important in the digital world, used in many fields and industries. Whether running a business, marketing products, conducting research, or seeking opinions, an efficient online form builder is a must-have tool.


Forms are the foundation of data collection. It is a link between you and the valuable data you seek.

However, in a world where data security and customization are critical, self-hosted form builders are gaining attention. These are not just tools; they offer autonomy in data management.

Let’s explore the universe of self-hosted form builders, where you can control your data.

What is a self-hosted form builder?

A self-hosted form builder is a software that lets users create and manage online forms on their own servers. This form builder provides greater control over data and the form-building process compared to traditional platforms.

With a self-hosted form builder, users install and run the form-building software on their servers or hosting infrastructure. Users control their data stored on their servers, not on external servers managed by a third-party service provider.

Organizations that value data ownership, privacy, and customization prefer using a self-hosted form builder. The form builder requires more technical setup than cloud-based options. However, many users believe that the control and security benefits outweigh the added complexity.

Open-source form builders offer several advantages, making it a preferred choice for individuals and organizations with specific needs and preferences. Here are some key reasons why someone might choose a self-hosted form builder:

  • Ownership: With a self-hosted solution, you have full ownership and control over the data collected through your forms. It is crucial for sensitive information and when compliance with data protection regulations is a priority.
