Not enough high-code developers. Rising demand. A backlog that keeps growing. For enterprise teams, the pressure to deliver innovation while maintaining openness, control, and flexibility has never been greater. At Betty Blocks, we believe low-code can do more. That’s why we’re introducing the Wasm-based Action Builder, a next step in bridging high-code flexibility with low-code speed.
Low-code platforms have often been seen as limiting, great for prototyping, but restrictive when advanced business logic or custom control is required. With the Wasm-based Action Builder, that perception changes.
High-code developers can now build reusable Wasm components in languages like Rust, Python, C#, or Java, and bring them directly into the Betty Blocks platform. Once imported, these components are modeled visually and made available as drag-and-drop building blocks. Low-code developers can then orchestrate them without writing code.
The result? A truly collaborative model where low-code builders extend their capabilities, while high-code developers enjoy more control and flexibility within the same environment.
One of the biggest challenges in enterprise low-code adoption is vendor lock-in. Proprietary technologies often tie your business logic to a single platform, raising concerns about long-term flexibility.
Enterprises increasingly adopt open-source software, yet many still rely on development tooling that produces proprietary software or comes with proprietary dependencies. Low-code platforms have historically shared this problem: most players are proprietary-based and have a strong lock-in. Betty Blocks is here to break the mold and offer a solution to the all-too-familiar vendor lock-in with the Wasm-based Action Builder.
By allowing actions to be exported as Wasm components, your business logic is no longer locked inside Betty Blocks. These actions can be portable and, in the future, run beyond the platform. This shift empowers enterprise architects and IT leaders to adopt low-code without compromising ownership or freedom.
By embracing WebAssembly, Betty Blocks opens the door to a wider range of skills and project types. Developers aren’t confined to JavaScript, and they can leverage the languages they know best. This inclusivity not only accelerates adoption within enterprises but also enables new types of projects to be built with low-code foundations.
