Mullvad Leta is a new privacy-focused search engine that runs on diskless servers, similar to Mullvad's VPN service. The servers operate on RAM only and utilize a custom kernel. While it aims to improve privacy by caching search results for up to 30 days, concerns have been raised about the efficacy of this approach due to potential data loss upon server reboots. Users have expressed skepticism about its authenticity and practicality, likening it to a publicity stunt or a proxy for existing services like Google. This sentiment is underscored by the search engine's restriction under certain conditions, indicating potential limitations in usability. Users also question the costs associated with operating such a service and whether it truly offers significant privacy enhancements in comparison to standard browsing setups.
