Duolicious – Open-source dating app

Duolicious is an open-source dating app built as a fork of the original Tinder (which used a similar open-source codebase). It positions itself as a privacy-focused, community-owned alternative to mainstream dating platforms like Tinder, Bumble, and Hinge. Being open-source means its code is publicly visible and auditable, theoretically reducing risks of data misuse, opaque algorithms, or sudden policy changes by a central company. The app is developed by volunteers and relies on community contributions rather than venture capital, which appeals to users who are skeptical of big tech's handling of personal data and dating algorithms. The project is hosted on GitHub, a platform where software developers collaborate on open-source projects.
