This is based on private evaluation of a prerelease security product. I cannot comment further other than I am impressed by its output. This commit is a squash of several commits. The impactful commits have details underneath markdown heading twos. ## fix(metrics): don't expose pprof by default pprof[1] is the Go standard library profiling toolkit. It is invaluable for diagnosing how Go programs perform in the wild. However it also is able to expose secret data set with command line flags. This is not ideal and should be mitigated by correctly configured firewall rules. We don't live in a world where people correctly configure firewall rules, so we have to fix things for people. Welcome to 2026.

Ref: AWOO-002 ## fix(policy): mend an edge case with subrequest auth and query strings This fixes an unlikely edge case where using subrequest auth and query strings with path based filtering can cause reality to differ from administrator intent. This effectively strips the query string from subrequest auth checks. This deficiency should be fixed in the future. Ref: AWOO-004 ## fix(expressions): mend possible nil pointer deref edge case If Anubis just started up, load averages may not be set in memory. This can cause a nil pointer dereference which could fail requests with weird errors until the async thread sets the load averages. Ref: AWOO-005 ## fix(lib): mend case where domainless redirects could allow cross-domain redirects Ref: AWOO-009 ## fix(expressions): validate randInt bounds before rand.IntN Non-positive or platform-overflowing arguments to the CEL randInt helper used to reach rand.IntN unchecked, surfacing a CEL evaluator error during request processing when policies passed attacker-influenced values (e.g. contentLength). Reject non-positive bounds and detect int narrowing explicitly, returning a typed CEL error in both cases. Ref: AWOO-010 Signed-off-by: Xe Iaso <xe.iaso@techaro.lol>

Overview
Anubis is a Web AI Firewall Utility that weighs the soul of your connection using one or more challenges in order to protect upstream resources from scraper bots.
This program is designed to help protect the small internet from the endless storm of requests that flood in from AI companies. Anubis is as lightweight as possible to ensure that everyone can afford to protect the communities closest to them.
Anubis is a bit of a nuclear response. This will result in your website being blocked from smaller scrapers and may inhibit "good bots" like the Internet Archive. You can configure bot policy definitions to explicitly allowlist them and we are working on a curated set of "known good" bots to allow for a compromise between discoverability and uptime.
In most cases, you should not need this and can probably get by using Cloudflare to protect a given origin. However, for circumstances where you can't or won't use Cloudflare, Anubis is there for you.
If you want to try this out, visit the Anubis documentation site at anubis.techaro.lol.
