Opal

As a no-code AI app builder from Google Labs, Opal differs from most in that you describe what you want in plain language and get a working mini-app, with hosting already taken care of.

Opal lets you discover, build, edit and share these mini-apps without writing code.

Each one is a multi-step flow that chains prompts, model calls and tools together.

You can work in a visual editor built around a node-based workflow, so the steps of an app are laid out where you can see and change them.

That makes it a reasonable fit for rapid prototyping, since an idea can become a usable app in minutes.

Because Opal runs the hosting, finished apps are usable and shareable straight away, with no deployment setup on your side.

The catch is that you are building mini-apps and flows, not full software products with custom code.
