See what AI bots cost your site. Then cap them.

BotBill is a WordPress plugin that shows how many requests and how much bandwidth GPTBot, ClaudeBot, Bytespider and 100+ other crawlers take from your server, in dollars. Then it blocks or rate-limits them for real, not just with a robots.txt line they can ignore.

Why robots.txt isn't enough

Bots can ignore it

robots.txt is a polite request. Badly behaved crawlers, and bots that fake a browser name, ignore it.

You can't see the cost

Host dashboards show total bandwidth, not which bot used it. You can't decide what to block without that.

Blocking everything has a price

Some AI crawlers send you visitors. Cut the expensive ones, keep the useful ones.

What BotBill does

Cost per bot

Requests, bandwidth and estimated cost for each crawler, by day, at your host's price per GB.

Real blocking

Return 403 to the bots you choose, before WordPress spends time building the page.

Rate limits

Allow a crawler, but only 100 pages an hour. Keep the traffic, lose the load spikes.

Fake-bot check

Checks claimed crawlers against their companies' published IP ranges and flags impostors.

Questions

Does it slow my site down?

It records a few fields per crawler request and checks the user agent early, before the page is built. Human visitors are not logged.

Does it see pages served from a CDN or cache?

It counts requests that reach WordPress. If a CDN such as Cloudflare answers a request first, BotBill won't see it, and the CDN's own logs are the place to look.

Is my data sent anywhere?

No. Logs stay in your WordPress database.

BotBill isn't out yet

I'm checking whether enough people want it before building it. Leave your email and you'll get Pro at the launch price of $29/year. No payment now, one email at launch, nothing else.
