Google has introduced Opal, an experimental tool for creating mini AI applications without the need for coding. This tool combines visual blocks and natural language instructions and is currently being tested in the United States.

Opal: Google’s New Coding-Free Development Tool
On July 24, 2025, Google announced its latest innovation through a blog post. While Google had previously ventured into AI-assisted coding tasks with its tool named Jules, Opal marks the company’s first foray into “vibe coding.” Unlike Jules, which automates development tasks by interacting directly with source code, Opal allows anyone to create mini AI applications by simply describing their intentions, without writing any code.
Google suggests that Opal is perfect for speeding up the prototyping of ideas and AI workflows, demonstrating a proof of concept with a functional application, creating customized productivity tools, and much more.
Opal not only automates code through AI but also facilitates the design of tools that incorporate AI capabilities. This feature is reminiscent of the one recently introduced by Claude in its Artifacts. However, unlike its competitor, Google does not provide access to the underlying code or APIs; everything is managed through a closed, visual interface.
How Opal Works According to Google
Google has designed Opal’s interface to be exceptionally user-friendly. There are two main modes available:

- Editor, where users can visually assemble the blocks that define the application’s functionality (input, processing, output), with guidelines on how these blocks interact.
- App, which presents a simplified, interactive version of the application as it will appear to end-users.
Users can switch freely between these modes to test, tweak, or refine their application’s appearance. Each block can be configured or modified using the mouse, or by simply describing the desired functionality in natural language through a prompt bar. Once the application meets their satisfaction, it can be shared instantly via a URL.
Those eager to try out Opal will need to be patient a bit longer. The platform, still in public beta, is currently only available to users in the United States. Google has not yet disclosed any plans for a broader rollout.
