Residential vs datacenter vs mobile proxies

A proxy gives each browser profile its own IP address and location. Choosing the right type — and assigning one dedicated proxy per profile — is one of the biggest factors in keeping multiple accounts separate and trusted.

What type of proxy fits which workflow?

It depends on how sensitive the platform is and your budget:

Proxy type	Trust level	Speed	Cost	Best for
Residential	High — real ISP IPs	Medium	Medium	Most multi-account work; social, e-commerce
Mobile	Highest — carrier IPs shared by many users	Medium/variable	High	The most sensitive or high-value accounts
Datacenter	Lower — easy to flag	Fastest	Lowest	Scraping public data, low-risk tasks

As a rule of thumb: residential is the default sweet spot, mobile is the safest for your most important accounts, and datacenter is for speed-sensitive, low-risk jobs where detection matters less.

How many accounts can I run per proxy?

For logged-in account management on sensitive platforms, use one dedicated IP per account. Sharing one IP across many accounts is a classic way to get them linked — if one is flagged, the others on the same IP are at risk. Rotating proxies are great for scraping, but for accounts you log into, a sticky, per-profile IP is safer.

Match the proxy to the fingerprint

A proxy alone isn't enough. The profile's timezone, locale, and language should match the proxy's region — a US IP paired with a Moscow timezone is an obvious mismatch. Good multi-profile browsers keep these aligned automatically.

How do I assign a proxy to a profile in Alias Browser?

Alias Browser lets you attach a specific proxy (HTTP, HTTPS, or SOCKS) or a built-in WireGuard VPN tunnel to each profile individually. You can test a proxy's connectivity before launching, and the browser keeps each profile's timezone and locale consistent with its assigned region — so every identity has a clean, coherent network footprint.
