Parahub is an open-source civic platform developed by a nonprofit organization from Portugal, designed to help people trade, communicate, and coordinate without relying on corporate middlemen. It brings a market, payments, messaging, governance, and mobility tools together in one app, with zero commissions. Users can buy, sell, or barter directly, including through multi-step exchanges when a straightforward swap is not possible. Its bankless finance features display prices in euros and US dollars and support instant payments with near-zero fees.

Parahub also offers identity and reputation profiles built through personal endorsements, encrypted messaging with an anti-spam micro-fee for first-time messages, and tools for signing agreements, resolving disputes through community arbitration, and voting or delegating votes. For travel, community maps provide carpooling, public transit routes, and vehicle tracking. The platform describes itself as privacy-focused and decentralized, with public code that users can inspect, adapt, or run independently. Community mesh networks are intended to help neighbors stay connected during internet outages.
