MultiZen
MultiZen relaunched in 2026 as a free desktop app that lets AI agents drive isolated profiles over MCP, after the original multi-session browser sat unchanged from 2023 to 2025. GitHub reports from mid-2026 cover launch failures on Ubuntu 24.04 and Intel Macs, an ignored time-zone setting and DNS errors, most fixed within days. Independent reviews are still rare.

MultiZen is free and MIT-licensed with no paid tier, account or license server, and its site lists unlimited profiles at $0. Each profile runs either the CloakBrowser Chromium engine or Camoufox (Firefox), and the site calls the project open core.

Product
After no updates between mid-2023 and 2025, MultiZen was rebuilt in early 2026 from a multi-session browser into an MCP-driven antidetect profile manager for AI agents.

Antidetect browsers are used to run several accounts side by side, for ad verification and for privacy. Using them to break a platform’s rules can still get accounts banned.
