Deepwiki was instrumental in our refactor of a large codebase away from playwright to pure CDP @ browser-use. Huge props to the team that built it, I regularly refer to it as one of the few strictly net positive AI coding tools.

The auto-overviews and diagrams are great, but where it truly shines is the "deep research" follow-up questions system at the bottom. It's much better than using OpenAI deep research of perplexity to ask questions about complex codebases like puppeteer/playwright/chromium/etc.
