Veilus is a desktop anti-detect browser for running many accounts on one computer, with automation your AI assistant writes and runs over MCP.

The problem: separate accounts on one machine can get linked through a shared fingerprint, cookies and IP address, and automating them by hand is slow and fragile.

Key features:

• Its own fingerprint and proxy (HTTP or SOCKS5) for every profile, on Veilus's own patched Chromium engine
• Built-in MCP server: Claude Code, Cursor or any MCP client can create profiles, drive pages, and write and test Playwright scripts
• Batch runs and schedules across profiles
• An approval step: a script added over MCP runs on at most 3 profiles until you approve it in the app
• Profile data stays on your machine; optional Veilus Sync copies it to your own Git repository or Google Drive

Who it is for: agencies managing client accounts, sellers with several storefronts, QA teams checking a site across devices and locations, and developers automating browsers with AI assistants.

Getting started: download for Windows 10/11 (x64) or macOS 13.5+ (Apple Silicon) at veilus.io. Free for 5 profiles on one device; the MCP server, local API and scripts need a paid plan or the 7-day Pro trial.

What makes it different: automation is built for AI assistants from the start, with a human approval step before anything runs unattended.
