Why ClaudeBot traffic triggers usage limits on Vercel Hobby plan

Problem

  • ClaudeBot request surge triggered a Vercel block/limit on my Hobby account.
  • Even with Vercel Firewall blocking the traffic, it seems to still count toward Hobby plan usage.
  • Because of the block/limit, my microfrontend deploy is restricted (so I can’t add files like robots.ts / sitemap.ts).

Questions

  • Need to know the block trigger + how long until deploy is unlocked/reset.
  • Whether Firewall-blocked requests still count toward Hobby usage.

Thanks in advance for any guidance.

I’ve prevented auto blocking on your account for the next 30 days. I hope that helps!

ClaudeBot traffic counts toward your Hobby plan’s Edge Request limit (1M/month) even when blocked by Vercel Firewall. Only traffic blocked by Attack Challenge Mode, persistent IP blocks, or DDoS mitigation doesn’t count toward usage.

I recommend using the AI Bots Managed Ruleset to block ClaudeBot and similar crawlers.
