PublicWWW Source Code Search

Search website source code via the PublicWWW API. Requires PUBLICWWW_KEY env var.

Caveat: PublicWWW indexes server-rendered HTML source only. CMPs injected purely via client-side JavaScript (e.g. tag managers, async script loaders) may not appear in results.

API

Download search results as CSV:

https://publicwww.com/websites/SEARCH_QUERY/?export=csvsnippetsu&key=$PUBLICWWW_KEY

CSV format: url;rank;snippet (one site per line, sorted by popularity rank).

Use export=csv instead of csvsnippetsu to get domain;rank without snippets.
