BitBrowser Complete Setup Guide: Integrate Rainproxy with BitBrowser

BitBrowser is an antidetect browser for people who run several online accounts and need each one to look like a separate person. Every profile gets its own fingerprint — canvas, WebGL, fonts, timezone, hardware — so a platform can't tie your accounts together.

That only works if the connection underneath matches. A perfect fingerprint arriving from a flagged datacenter IP is still a flagged visit. This guide covers the whole setup with Rainproxy: where the credentials come from, how the username string works, how to hold one IP for a session, and the small settings that decide whether a profile survives its first week.

Who BitBrowser is for

• E-commerce sellers running multiple stores
• Social media marketers running multiple accounts
• Affiliate marketers managing campaigns
• Ad buyers running several ad accounts
• Privacy-conscious users who want profiles kept apart

What BitBrowser gives you

Fingerprint management — a unique browser fingerprint per profile, hardware spoofing, and timezone and geolocation you set yourself.

Multi-account management — unlimited profiles, each running independently, with team sharing if you work with other people.

Set the timezone and language to match the country of the proxy. A US IP on an Amsterdam clock is one of the easiest mismatches for a platform to spot.

Why pair it with Rainproxy

• Residential proxies — 110M+ rotating residential IPs
• Mobile proxies — real 4G/5G carrier IPs
• ISP proxies — 50,000+ US ISP-hosted IPs with unlimited bandwidth
• Session control — sticky sessions by second, minute or hour
• Quality filtering — clean IPs, checked before they reach you
• 250 MB on us when you sign up with Google, no card needed
• 24/7 support — live chat, Discord and email

Part 1: Rainproxy setup

Step 1 — open your dashboard. Log in and you'll land on your plans. No account yet? Sign up with Google and the first 250 MB is free.

Step 2 — pick your proxy type. Residential for general work and scraping, mobile for the strictest social platforms, ISP when you want one address that never changes.

Step 3 — generate the endpoint. Open the endpoint generator and set your targeting:

• Country — the market you're working in
• State / city — optional, for local pricing and local results
• Session control — how long one IP should stay with you
• Speed — optimisation level from 1 to 10

Step 4 — copy the credentials. You'll get something in this shape:

Host:     resi.rainproxy.io
Port:     9090
Username: yourname-country-us-session-abc123-sessTime-30
Password: your account password

HTTP, HTTPS and SOCKS5 all work. All targeting lives in the username, so nothing extra needs configuring inside BitBrowser.

Part 2: BitBrowser configuration

Step 5 — launch BitBrowser and open Browser Profiles in the left sidebar.

Step 6 — click the blue Add button.

Step 7 — fill in the basics. Give the profile a name you'll recognise six months from now, like Rainproxy - US - Store 1. Group profiles by purpose, pick the platform, and set Multi-open to Allowed.

Step 8 — scroll to the proxy block and enter:

• Method: Custom
• Lookup channel: DB-IP
• Type: HTTP, HTTPS or SOCKS5
• Protocol: IPv4
• Host: resi.rainproxy.io
• Port: 9090
• Username: your username with targeting options
• Password: your Rainproxy password

Hit Check proxy before saving. It should come back with the country you asked for. If it shows the wrong country, the targeting flag in the username is wrong — fix it there, not in BitBrowser.

Username flags worth knowing

Flag	What it does
country-us	Country targeting
state-newyork	State targeting
city-miami	City targeting
session-abc123	Names a sticky session
sessTime-30	Holds that session for 30 minutes
speed-[1-10]	Speed optimisation level
quality-[low/medium/high]	IP quality filtering
strict-[1-10]	Location accuracy level

Details that decide whether the profile lasts

One session per profile. Give each profile its own session- value. Two profiles sharing an IP is the fastest way to get them linked.

Match the timezone. Set it to the proxy's country, not yours.

Leave WebRTC on BitBrowser's default. Its replace mode reports the proxy address. Turning WebRTC fully off is itself unusual and stands out.

Warm the profile up. Browse normally for a few minutes before logging in. A brand-new fingerprint whose very first action is a login attempt looks like exactly what it is.

Keep the same IP with the same account. Sticky sessions exist for this. An account that hops countries between logins gets checked.

Support

• Rainproxy: live chat on the site, Discord and email, 24/7
• BitBrowser: bitbrowser.net/contact

You're set

That combination gives you isolated profiles on top of 110M+ residential IPs, with country, state, city and ISP targeting and sticky sessions when you need them. Start on the free 250 MB, prove the setup on one profile, then scale. If anything looks off, our team would rather hear from you early than after a ban.
