mosparo is an open-source, self-hosted spam protection tool from Switzerland that replaces traditional CAPTCHAs.

mosparo is an open-source spam protection project based in Switzerland (EFTA). It is designed to be self-hosted, giving website owners full control over how form submissions are protected.

mosparo blocks spam through accessibility-friendly checks without showing users image puzzles, runs entirely on infrastructure you control, and avoids third-party tracking. As an open-source, self-hostable European tool, mosparo is a strong alternative to Google reCAPTCHA for organisations that want spam protection without external dependencies.
