Open Source Alternatives to DuckDuckGo

A search engine and privacy suite that provides a private search experience, a web browser, and browser extensions to block web trackers. The product is designed for users seeking privacy alternatives to mainstream search engines and browsers. It is deployed as a web service, a standalone browser application, and browser extensions. The platform offers a free tier for basic search and browsing needs. Paid subscription tiers, specifically the Plus and Pro plans, expand the functionality by adding a VPN, personal information removal services, and identity theft restoration.

The software is available for download across various operating systems and as an extension for existing browsers.
