A Graphical User Interface (GUI) is a visual interface that lets users interact with computers using icons, buttons, and menus instead of text commands. For software developers, these tools offer a bridge between complex coding and visual design, allowing for greater focus on core functionality. UI/UX designers rely on GUI software to experiment with layouts and interactions.
The problem is many struggle to find tools that balance enhanced functionality with ease of use. Developers often face challenges in customizing pre-built components to meet specific project needs, while designers may feel limited by inflexible templates. Plus, the high cost of some GUI solutions can put them out of reach for smaller teams or individual developers.
This article presents the top 10 GUI software tools of 2024 that offer high customization, robust features, and seamless integration capabilities. So, by the end, you'll have a clear understanding of which tools can help you prototype interfaces quickly and streamline the interface design process.
What is GUI software?
GUI software refers to tools that enable designers and developers to create visual interfaces for applications, websites, and other digital products. These tools allow users to design, prototype, and sometimes even code interfaces using graphical elements rather than relying solely on text-based programming.
Why use GUI software?
Let's explore three key advantages of using GUI software:
- Rapid prototyping: GUI software allows designers to quickly create and iterate on interface designs. With drag-and-drop functionality and pre-built components, you can assemble prototypes in a fraction of the time it would take to code them from scratch. This speed enables more experimentation which often leads to better design outcomes.
- Improved collaboration: Most GUI tools offer features that facilitate teamwork, such as real-time editing, commenting, and version control. This collaborative environment allows designers, developers, and stakeholders to work together seamlessly.
- Consistency and scalability: Many GUI tools include design systems and component libraries, making it easier to maintain consistency across large projects. This feature is particularly valuable for creating cohesive user experiences in complex applications.

How to choose the right GUI software
Choosing GUI software doesn't have to be a headache. Check out these important factors before you decide:
- Ease of use: The interface is just the beginning of understanding a tool's usability. Complex tasks, like creating interactive prototypes or setting up design systems, will show you the true depth of user-friendliness. After a week of use, the tool's intuitiveness becomes apparent, so you'll probably come across any quirks or shortcuts you've had to learn. Plus, the keyboard shortcuts can impact ease of use and save you a few clicks, so don't neglect this one.
- Integration capabilities: Smooth integration with current tools is essential for maintaining a seamless workflow. Adobe Creative Suite and Sketch are common integrations but look beyond these. Consider integrations with project management tools like Jira or Confluence for better team coordination. Data-driven design? Check for Airtable, Typeform, or database connections to power dynamic prototypes. Don't forget about communication tool integrations like Slack, which can improve team collaboration.
- Export options: Standard formats like PDF and various image formats (PNG, JPG, SVG) should be available, but that's just the baseline. Look for options to export design specs or developer handoffs in formats that your development team prefers. Check if you can export to HTML/CSS for quick prototypes. Some tools offer the ability to export to other design software formats, which can be useful for cross-tool workflows.
- Pricing and plans: Analyze the pricing structure across different tiers and calculate the long-term cost based on your expected usage and team growth. For example, look for any hidden limits, such as restrictions on file storage, export options, or the number of collaborators on each plan. Also, check for any volume discounts for teams or educational pricing if applicable. For larger organizations, inquire about custom enterprise plans that might offer better value. Many companies, like Softr, provide enterprise tiers with advanced security and integration capabilities.
- Trial availability: The trial period should accommodate a real project timeline - 14-day trials are common, but longer is better. Then, check if the trial requires a credit card - no-card-required trials reduce the barrier to testing. Look for any limitations during the trial period, such as export restrictions or team size limits. Some companies even offer a money-back guarantee period after purchase, so you can consider this as well.
- Learning resources: Evaluate the depth and breadth of learning materials available. For example, check for a comprehensive, regularly updated knowledge base or documentation. Then, if applicable, assess the activity level and helpfulness of user forums or community platforms offered by the company since a community can be an invaluable resource for problem-solving. Also, evaluate any certification programs or academies offered. Lastly, look for interactive workshops, similar to what Softr provides, for hands-on learning experiences.
