Freeter is a free, open-source productivity app that helps developers and designers eliminate browser tab overload by creating custom workflows that search multiple sites simultaneously. Users can set up templated queries to instantly pull results from sources like Stack Overflow, Copilot, and DuckDuckGo for coding questions, or search icon repositories like Flaticon, Icons8, and The Noun Project side-by-side. The tool allows quick access via keyboard shortcuts and focuses on maintaining workflow efficiency without ads or subscriptions.
