fedi‑map

A map of how fediverse instances connect, and how those connections change over time.

No posts, media, or account names are stored. fedi-map uses public instance metadata and daily aggregate counts.

If you found this crawler in your logs, it identifies itself as:

fedi-map/0.1 (+https://map.wizard.casa/about)

For instance admins

Opt-in and opt-out requests must come from a staff account published by the instance.

Remove your instance and its data

Send a direct message saying “opt out” to @fedi-map@wizard.casa.

You can also contact @nimda@wizard.casa and name the domain you want removed.

Opting out stops crawling and deletes the data collected about your instance. Only the domain and an opt-out flag are kept to prevent another crawl.

Stop crawler requests with robots.txt

Add this to https://your.instance/robots.txt:

User-agent: fedi-map
Disallow: /

This blocks crawler requests. It does not delete data already collected; use the opt-out above for that.

Opting in

As an instance admin, send a direct message saying “opt in” to @fedi-map@wizard.casa. This reverses an earlier opt-out and lets smaller instances join the map.

What is collected

Public instance metadata, including software, user count, and peers.
Daily post and mention counts from public timelines.
Origin domains and timestamps from public live activity.

Public timelines are read for instances with at least ten users. Smaller instances can opt in.

Crawl load

At most one request per host runs at a time. fedi-map respects robots.txt, rate limits, and Crawl-delay. The average is about 0.68 requests per instance per day.
