Competitor map

Each alternative by how close its vector is to 5ch.io’s (x) and how much traffic it gets, how much of the stack it shares, or where it sits in the embedding space itself (y). Lines split each axis at the median. Hover for the numbers, click to jump to it in the list.

We can’t read 5ch.io’s homepage (bot protection page), so it’s compared on what Wikidata and Wikipedia say about it.
