Afina Browser is a professional antidetect browser designed for secure, scalable, and realistic multi-account management. It helps marketers, agencies, eCommerce teams, and automation professionals safely manage multiple online identities while avoiding detection, tracking, and account bans. Unlike traditional antidetect browsers that rely on aggressive fingerprint spoofing, Afina prioritizes realistic browser behavior. Each browser profile is built using consistent, real-world device characteristics, reducing fingerprint collisions and improving long-term account stability. Profiles are fully isolated to prevent cross-tracking, data leakage, and session correlation. One of Afina’s key differentiators is its native SOCKS5 UDP support, enabling real QUIC and HTTP/3 traffic through proxies. This allows websites to observe authentic modern network behavior instead of forced TCP fallbacks, which are increasingly detected by advanced anti-fraud systems. Afina does not simulate QUIC — it runs it natively. Afina follows a local-first security architecture. All browser profiles, cookies, and session data are encrypted and stored locally or in the user’s own cloud storage. Encryption keys remain under the user’s control, ensuring maximum privacy and protection even in the event of infrastructure compromise. Built for professional use, Afina Browser supports unlimited browser profiles, advanced proxy management, tagging and grouping, team collaboration with permission controls, and a local API for automation and integrations. Profiles remain stable across long sessions and restarts, making Afina suitable for daily operations and large-scale workflows. By combining realistic fingerprints, true network behavior, strong encryption, and modern protocol support, Afina Browser delivers a reliable and future-proof solution for professional multi-account management.
