I usually ask Claude Code to setup a software stack that can build/run whatever I am working on. Then I let it browse a website or navigate through screens. I also use Playwright to get screenshots of the website I am building. For e.g. apps or whatever application you are building, there should be a way to get screenshots too I guess.

Added benefit is that when Claude navigates and finds a bug, it will either add them to a list for human review or fix it automatically.

Pretty much a loop where building and debugging work together;-)
