Antidetect browser for multiple accounts.Native on Windows and Apple Silicon Macs.
A separate browser, device fingerprint and proxy for every account you run, from one desktop app — so no two accounts share cookies, storage or a device identity.
Tested against these identity checkers
How it works
Three steps from install to your first isolated browser session.
Create a profile
Name your profile and choose an OS. JustBrowser generates a complete, consistent device identity across 40+ parameters -- screen, timezone, hardware, and more.
Assign a proxy
Attach an HTTP, HTTPS, or SOCKS5 proxy so each profile's location matches its identity. Run a health check to verify connectivity before launch.
Launch & browse
Hit Start. A dedicated Chromium instance opens with your profile's identity and proxy active. Close it whenever -- your session persists for next time.
Every profile looks like a real device
JustBrowser creates a complete, internally consistent browser fingerprint for each profile -- canvas, WebGL, audio, fonts, screen, timezone, language, and 30+ more parameters. Built on a custom Chromium engine with native C++ integration, not browser extensions.
- Canvas & WebGL rendering (native C++ level)
- GPU identities matched to the device class
- OS-accurate font lists
- Navigator & platform configuration
- AudioContext isolation per profile
Complete data separation between sessions
Each browser profile runs in its own isolated environment with separate cookies, localStorage, IndexedDB, cache, saved passwords, and extension state. No data crosses between profiles, ever. Close a profile and re-open it days later -- everything is exactly where you left it.
- Persistent sessions across restarts
- Per-profile user data directories
- Independent extension installs
- Isolated cookie jars
Dedicated proxy per profile
Assign HTTP, HTTPS, SOCKS5, or residential proxies to individual profiles. Built-in health checks verify connectivity and measure latency before you launch. WebRTC protection keeps each profile's network identity consistent.
- HTTP / HTTPS / SOCKS5 support
- Works with rotating residential gateways
- One-click health checks with latency
- WebRTC protection built in
- Bulk assignment across profiles (round-robin or random)
curl -X POST http://127.0.0.1:36542/api/v1/profiles \
-H "Authorization: Bearer <token>" \
-H "Content-Type: application/json" \
-d '{
"name": "Campaign-US-01",
"os": "windows"
}'
# then attach a proxy
curl -X PUT http://127.0.0.1:36542/api/v1/profiles/<id>/proxy \
-H "Authorization: Bearer <token>" \
-H "Content-Type: application/json" \
-d '{"proxy_id": "<proxy_id>"}'Automate everything via API
Full REST API to create profiles, configure identities, assign proxies, and launch browser sessions programmatically. Integrate JustBrowser into your existing automation stack with a few lines of code.
- Profile CRUD operations
- Identity generation & configuration
- Headless browser launch via CDP
- Batch start & stop across many profiles
- OpenAPI documentation included
Mature profiles from day one
Every profile can route DNS through encrypted providers (Cloudflare, Google, Quad9). Combined with automated cookie warm-up, profile aging, and real-time health scoring, each profile looks like an established user account — not a freshly created one.
- DNS-over-HTTPS per profile (Cloudflare, Google, Quad9)
- Cookie warm-up across 127 curated sites
- Profile aging with realistic browsing history
- Real-time health score across 50+ checks
- Custom Chromium engine, rebuilt as upstream Chromium moves
- Built at the C++ level, not browser extensions
Who uses JustBrowser
Teams and individuals who need to operate multiple accounts, verify content across locations, or automate browser workflows at scale.
Social Media Management
Run dozens of social accounts from one place. Each profile gets its own fingerprint, cookies and storage, and you can assign it its own proxy, so each account runs from a separate identity and IP.
E-commerce & Dropshipping
Manage multiple seller accounts on Amazon, eBay, Shopify, and other marketplaces, each in its own isolated profile with a separate fingerprint, cookie jar and proxy.
Affiliate Marketing
Scale campaigns across networks and traffic sources. Each campaign runs through its own clean profile with a dedicated proxy.
Ad Verification
Check how ads render across geos, devices, and browsers. Verify placements, detect fraud, and audit competitors from any location.
Web Scraping
Give each scraping job its own profile and proxy. Every session runs with a distinct browser fingerprint and, with a proxy assigned, a distinct IP and location.
QA & Testing
Test web apps across different browser configurations, screen sizes, timezones, and locales without spinning up VMs.
One plan. Everything included.
No tiers, no per-profile pricing, no per-seat pricing. Start with a 7-day trial — cancel before it ends and you are not charged.
Billed monthly. Cancel any time.
$99.99 billed once a year
Both options start with the same 7-day trial and ask for a card up front, so nothing stops working the day it ends. Team seats are free: invite as many teammates as you like and each one can run the profiles you share with the team. Teammates need their own subscription to sync profiles of their own and to use the API.
How JustBrowser compares
Multilogin, GoLogin and AdsPower all charge more as you add profiles, and a team means seat fees or a higher tier. We don't — $9.99/month is the whole bill.

What 100 profiles and 3 teammates actually costs
Monthly billing, compared like for like — every vendor here also advertises a lower annual rate.
Unlimited profiles, unlimited teammates. The same bill at 10 profiles or 10,000.
Priced per profile in tiers — the bill grows with every profile, and each teammate is a separate charge.
Their entry plan cannot have team members at all — sharing work with anyone means their Business plan.
Priced by profile count across Pro and Business tiers; unlimited seats only once you are on Business.
Competitor figures read from each vendor's own pricing page on 20 September 2026: AdsPower, GoLogin, Multilogin. Prices change and promotions run constantly — check theirs before deciding. Ours is on this page and does not vary by usage.
