As answered by people managing DevFinanceTools and RepIndex.org.
RepIndex.org's answer:
RepIndex is community reputation for social accounts — votes plus reasons from real people, not a secret model or platform score. One entity can link X and Instagram handles. Beyond ratings you get public lists, zero-knowledge encrypted private lists, notes, OSINT badges (shown separately from votes), Pulse stories, and a free Chrome extension for live badges on X.
RepIndex.org's answer:
Most social analytics tools measure reach or sentiment. RepIndex is built for trust: reason-backed community votes, weighted scoring against brigading, optional anonymous vote direction, and OSINT context without mixing it into the score. Public and encrypted private lists plus notes help researchers organize accounts without leaking watchlists. Free EN/FA web + Chrome extension.
RepIndex.org's answer:
RepIndex.org's answer:
People who need context before they trust or amplify an account: Iranian/Persian X users and diaspora communities dealing with spam, scams, and coordinated propaganda; plus researchers, journalists, and anyone screening sellers, collaborators, or sources on X (and Instagram-linked profiles on the web).
RepIndex.org's answer:
RepIndex started from Iranian X discourse — including “white simcard” accounts that bypass censorship while ordinary users are blocked — and the need for transparent, community-driven trust signals. It grew into a free reputation layer: vote with reasons, browse Pulse and analytics, organize lists (including encrypted private ones), and check live scores via a Chrome extension on X.
RepIndex.org's answer:
Chrome Extension (Manifest V3), Vue.js website, Express API, Supabase/Postgres, Coolify hosting. Client-side Web Crypto (AES-256-GCM / Argon2id) for encrypted private lists. X OAuth for sign-in. EN/FA localization.
