The sweet spot: an IDE you do not have to install, with an agent when you get stuck.
The IDE is in the browser, which matches this preference.

A good step up once you can follow a change even if you did not write every line.

If you do not want to read code

The order changes. Editor tools drop, even when they are famous.

1. Replit · fit 84
2. Bolt.new · fit 77 — You can fake a simple browser game. This is not a game toolchain.
3. Lovable · fit 77 — The canvas is a web app builder, not a game engine.

Editor and CLI tools move up. Browser builders stay useful for a first UI pass.
