Community find. Not personally tested by Ash.

What it does

Replit combines a browser-based development workspace with AI assistance and publishing tools. It gives you a place to inspect the project as you move from a written idea to a running app.

When to use it

You want to build and inspect a prototype without first configuring a local development environment.

What you need: A Replit account and a small app idea with a clear success condition.

Try a small build

A suggested exercise to help you evaluate the resource.

Create a project for a simple habit tracker using sample data. Describe how checking and unchecking a habit should behave.
Run the app and inspect the files. Check whether refreshing the page preserves or resets the data, and decide what you need.
Test an empty list and a long habit name before exploring deployment. Read the current publishing and usage requirements.

You should end up with: A running prototype and a clear understanding of where its data lives.

Keep in mind

A working preview does not prove that authentication, storage, or production configuration is complete.
