interesting!

Thanks! Curious what you're running — are you seeing AI bot traffic on your site? Would love to know if the log formats you use are covered (Nginx, Apache, Cloudflare CSV, Vercel JSON supported right now).
len_chapaty•24m ago
nice, how are you calculation the cost?
newscombinatorY•20m ago
Hopefully not by using another AI bot... ( ͡° ͜ʖ ͡°)
plaintosapp•17m ago
Nope, pure JavaScript in your browser. No AI bots were harmed or employed in the making of this tool.
plaintosapp•18m ago
Good question. The cost estimate uses two components:

1. Bandwidth: total bytes served to bots divided by 1GB, multiplied by $0.09/GB (AWS/Cloudflare blended average rate)

2. Compute: total bot requests divided by 1 million, multiplied by $0.40 (Vercel/Lambda average per million invocations)

Both rates are configurable assumptions — the real value is seeing the relative breakdown between bots and the order of magnitude of waste. Your actual cost depends on your specific hosting provider.

Also wrote up the background on Dev.to if anyone wants more context on how it works: [https://dev.to/plaintos_app_fd54e75a054e/i-built-a-free-tool...]

I ran it on my personal domain that has just some kind of landing page and nothing else on it, and it's not advertised anywhere:

0% of traffic is non-human · <$0.01/yr projected

Well, 0% of traffic is AI bots. 99% of traffic is vulnerability scanners actually.
