mosparo

Overview

mosparo is a modern, open-source spam protection system designed to effectively guard your website forms against unwanted spam messages. Unlike traditional CAPTCHAs that often involve puzzles or calculations, mosparo offers a seamless user experience, requiring no complex interactions from legitimate users. It focuses on analyzing form entries, IP addresses, and user agents to identify and block spam before it reaches your inbox.

One of mosparo's core strengths is its commitment to data privacy. It only processes the data entered into the form, along with the user's IP address and user agent, without collecting any other personal data or utilizing cookies. All stored data is automatically encrypted or hashed, and form entries are purged after 14 days, ensuring minimal data retention and enhanced privacy for both website owners and users. Its customizable design also allows it to blend perfectly with any website's aesthetic.
