* cmd/anubis: add a debug option for benchmarking hashrate Having the ability to benchmark different proof-of-work implementations is useful for extending Anubis. This adds a flag `--debug-benchmark-js` (and its associated environment variable `DEBUG_BENCHMARK_JS`) for serving a tool to do so. Internally, a there is a new policy action, "DEBUG_BENCHMARK", which serves the benchmarking tool instead of a challenge. The flag then replaces all bot rules with a special rule matching every request to that action. The benchmark page makes heavy use of inline styles, because currently all global styles are shared across all pages. This could be fixed, but I wanted to avoid major changes to the templates. * web/js: add signal for aborting an active proof-of-work algorithm Both proof-of-work algorithms now take an optional `AbortSignal`, which immediately terminates all workers and returns `false` if aborted before the challenge is complete. * web/js: add algorithm comparison to the benchmark page "Compare:" is added to the benchmark page for testing the relative performance between two algorithms. Since benchmark runs generally have high variance, it may take a while for the averages to converge on a stable difference. --------- Signed-off-by: Xe Iaso <me@xeiaso.net> Co-authored-by: Xe Iaso <me@xeiaso.net>
Anubis
Anubis weighs the soul of your connection using a sha256 proof-of-work challenge in order to protect upstream resources from scraper bots.
Installing and using this will likely result in your website not being indexed by some search engines. This is considered a feature of Anubis, not a bug.
This is a bit of a nuclear response, but AI scraper bots scraping so aggressively have forced my hand. I hate that I have to do this, but this is what we get for the modern Internet because bots don't conform to standards like robots.txt, even when they claim to.
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.
