About Bot Butcher

Bot Butcher is a spam-classification API for contact forms that replaces a CAPTCHA with a server-side LLM judgement on the message itself. Rather than asking the human visitor to prove they are not a robot by clicking traffic lights, the form submits normally and your backend posts the message to Bot Butcher, which classifies it as spam or legitimate and returns a verdict you act on. That inversion is the product's argument: the friction moves off the visitor and onto your server, so conversion on the form does not pay for the spam filtering, and there is no third-party widget loading in the browser and no reCAPTCHA cookie to disclose — the site publishes a privacy angle around exactly that. It is deliberately narrow: an API key, one endpoint, unlimited forms, and documentation aimed at wiring it into an existing contact-form handler rather than a dashboard product with its own form builder. The pricing is usage-metered with a genuinely free band for low-traffic sites, which fits the indie-site and agency-client use case it is aimed at — a portfolio or brochure site taking a handful of enquiries a month never pays anything, and cost only starts once volume implies the form is worth protecting.
