BETTY BLOCKS, Alkmaar, the Netherlands, August 27, 2025 – Betty Blocks, a leading innovator in low-code development, has announced the launch of Betty Blocks Open, making it the first low-code platform to leverage WebAssembly (Wasm) components as the foundation for generating applications. This groundbreaking step empowers enterprises to break free from vendor lock-in, giving developers unprecedented freedom to build, export, and fully own the code behind their applications.
Unlike traditional low-code solutions that confine users to closed ecosystems, Betty Blocks Open delivers true transparency and portability. Developers can now create components in multiple coding languages, such as JavaScript/TypeScript, Python, C/C++, C#, and Rust, and integrate them seamlessly into their low-code applications. Through the Wasm-based Action Builder, these components can be exported as reusable modules, deployed independently, or integrated into existing IT infrastructures.

Portable app components provide software architects with the flexibility to design systems that scale across various vendor platforms, dependencies, and technology stacks. Businesses can pivot without being held back by software rigidity and stay ahead of rapidly changing market demands.
“Most platforms force organizations to choose between speed and control,” said Chris Obdam, CEO and co-founder of Betty Blocks. “With Betty Blocks Open, enterprises no longer need to compromise. They can accelerate development while retaining complete control over their software. Wasm-based components ensure that innovation isn’t limited by proprietary systems.”
How Betty Blocks Open is disrupting the low-code status quo:
• Codebase ownership: Users always have access to the code of your applications built in Betty Blocks.
• Eliminate Vendor Lock-In: Export application components and deploy them anywhere, independent of the platform.
• Hybrid Development: Enable high-code and low-code developers to collaborate seamlessly.
• Wasm-Powered Performance: Run compute-heavy web apps, such as portals, client platforms, and data processing tools, at native speed in the browser.
• Tech-Stack Integration: Design flexible architectures that integrate with existing systems using open, non-proprietary standards.
By pioneering WebAssembly in low-code, Betty Blocks ensures that enterprises can build future-proof business applications without the risks associated with closed ecosystems. From running high-performance apps to integrating modular components across diverse environments, Betty Blocks Open puts developers firmly back in control.
“Enterprise IT should never be boxed in,” added Chris. “Betty Blocks Open represents the next era of low-code: fast where it should be, flexible where it must be, and open where it counts.”
