Public Beta — all plans free while we scale infrastructure

Frugal & fair pricing.

Because C and H2O run on almost nothing, our server costs are a fraction of traditional CAPTCHA services. We pass that directly to you.

All plans are completely free during the Beta — original prices shown for transparency.
