Websites treat datacenter and cloud IPs as higher risk, so an agent browsing from a VM often hits a 403, CAPTCHA, Cloudflare challenge, or throttle. A residential or mobile IP in the right country sometimes clears that. It is not a guarantee.
Aluvia runs a small proxy next to the agent. One command turns it on, and every tab leaves through a residential or mobile IP. Aluvia does not claim to beat fingerprint, Linux Chrome, TLS, or canvas. Do not use it for a normal login wall. If a login page appeared because the IP is a datacenter, changing to a residential or mobile IP is the job. A password, SSO, or 2FA problem is not.
