What is The Open Index?

A community-curated web directory — websites filed by subject by people, in the spirit of the early-web directories.

How is the index organised?

Sites are sorted by hand into 22 categories (794 listings in total), so you browse by topic instead of guessing keywords.

How do I add my site?

Hit “Add your site”, choose a category, and submit the URL — we fetch the description for you.

Do you review what gets added?

Yes, every submission is checked by a person to keep the index useful and free of spam.

About the Open Index

The Open Index is a free, community-curated catalogue of the web — 789 sites filed by hand into 22 categories. Think of it as a modern take on the directories that mapped the early internet: you browse by subject, stumble on sites a search engine would bury, and list your own for nothing. Nothing here is auto-generated or pay-to-rank; every entry is reviewed by a person and carries a short description lifted from the site, so the index stays honest and quick to scan.
