TabNews

Created by Brazilian developer Filipe Deschamps as an open-source, Hacker-News-style community for programmers and tech professionals, with a "tabcoin" reputation system for content quality. Fully open source with a public documented API (/api/v1/contents, /api/v1/users, /api/v1/status). Small but genuinely Brazil-native and senior-developer-focused, distinct from Reddit's general-purpose r/brasil community.
