InfoPeak Captcha stops bots without bothering your visitors and without sending their data to the US.
Instead of tracking visitors or making them click traffic lights, it uses proof-of-work: the visitor’s browser solves a small computational challenge in the background, the moment they start filling in a form. Bots pay a CPU cost that makes mass abuse expensive; humans wait a fraction of a second and never see a puzzle.
Why site owners choose it
What this plugin protects
Each can be toggled individually on the settings page.
Setup takes two minutes
You can try the plugin first with the public test credentials ipk_test_sitekey / ipk_test_secret – they work on any domain and never count against a quota.
This plugin relies on the InfoPeak Captcha service to do its job. The service is operated by InfoPeak and hosted entirely in the EU.
It is used for two things:
https://captcha.infopeak.io/infopeak-captcha.js is loaded in the visitor’s browser on the pages where a protected form appears. The browser then requests a challenge and submits the solved proof of work. This sends the site’s public sitekey and the computed solution. No cookies are set and no visitor is tracked.https://captcha.infopeak.io/api/v1/pow/siteverify and receives back whether the token is valid. Nothing about the visitor is included.No personal data about your visitors is stored by the service. See the privacy policy and the terms of service.
