What Is Octo Browser
Octo Browser, often written as OctoBrowser, creates isolated browser profiles, each with its own fingerprint, cookies, storage, and proxy. To a website, two profiles look like two unrelated devices. It runs on Octium, an in-house Chromium fork updated promptly after each Chromium release.
The company behind it is Blackbird Secure Browsing Ltd in London. Desktop builds cover Windows, macOS, and Linux, despite one ranking review listing only the first two.
How Octo Browser Fingerprinting Works
The keyword here is real device fingerprints. Octo draws from fingerprints collected on real hardware, so canvas, WebGL, audio, fonts, and CPU values stay consistent with each other. Mismatched combinations are what anti-fraud systems flag first, so this matters more than it sounds.
You can set over 50 parameters per profile or let Octo derive timezone, language, and geolocation from the proxy IP. Desktop profiles can simulate Android devices. Native mobile apps arrived in 2026, iOS in May and the Android app on August 10, with 100 free profiles during open testing. Reviews claiming Octo has no mobile app are outdated.
Octo Browser Pricing and Plans
Octo has five tiers, billed in euros before VAT. Lite is €10 per month for 3 profiles. Starter is €29 for 10, expandable to 30. Base is €79 for 100 profiles and the first tier with API access. Team is €169 for 350 profiles and 3 seats. Advanced is €329 for 1,200 profiles, 8 seats, and the highest API limits. Prepaying 12 months takes 30 percent off.
The two gates that matter are API at Base and team seats at Team. One review puts team sharing on Base, which is wrong. There is no free desktop plan or trial.
Proxy Support in Octo Browser
No plan includes proxy traffic, though there is a built-in proxy shop. Octo accepts HTTP, HTTPS, SOCKS5, and SSH proxies plus IPv6, and UDP support arrived in 2026 so WebRTC routes through the proxy instead of leaking your real IP. Paste host:port:login:password into the host field and Octo parses it. If your provider uses a different layout, a proxy formatter converts it.
Each profile needs its own sticky IP matching its location. Residential proxies are the default choice, since platforms flag datacenter ranges on sight, and Proxyon lets you set custom session lengths for exactly this.

Octo Browser API and Automation
The API has two parts. The cloud API is REST with an X-Octo-Api-Token header and handles profiles, proxies, tags, and team management. The local API runs inside the desktop app on localhost:58888, unauthenticated, and starts or stops profiles on that machine. Starting a profile with debug_port enabled returns a ws_endpoint, a standard Chrome DevTools address you hand to Playwright, Puppeteer, or Selenium. The full reference is in the official API documentation repo.
import requests
from playwright.sync_api import sync_playwright
LOCAL = "http://localhost:58888"
UUID = "YOUR_PROFILE_UUID"
start = requests.post(f"{LOCAL}/api/profiles/start", json={
"uuid": UUID,
"headless": True,
"debug_port": True,
}).json()
with sync_playwright() as p:
browser = p.chromium.connect_over_cdp(start["ws_endpoint"])
page = browser.contexts[0].pages[0]
page.goto("https://example.com")
print(page.title())
requests.post(f"{LOCAL}/api/profiles/stop", json={"uuid": UUID})Rate limits run from 50 to 1,000 requests per minute by plan, and local start and stop calls count against that budget. One-time profiles launch a throwaway profile in one request, which suits scraping. A headless Docker image runs profiles on servers.

FAQ Section
Is Octo Browser safe?
Profile data is stored encrypted in Octo's cloud, accounts support two-factor authentication, and you can add a separate password to individual profiles. The company states it has had no data leaks in its history. Safety on the platforms you use it on depends on your proxies and your behavior, not the browser alone.
Can I use Octo Browser for free?
Not on desktop. The cheapest plan is Lite at €10 per month for 3 profiles, and there is no trial. The iOS and Android apps are free during their open testing phase, with 100 free profiles for new users.
Does Octo Browser include proxies?
No plan includes proxy traffic. There is a built-in proxy shop where you buy bandwidth separately, or you can add proxies from any provider that supports HTTP, HTTPS, SOCKS5, or SSH.
Does Octo Browser run on Linux?
Yes. There is a native Linux build alongside Windows, macOS for Intel, and macOS for Apple Silicon. Docker images also exist for headless use on servers.
Which automation libraries work with Octo Browser?
Anything that speaks the Chrome DevTools Protocol. The official documentation covers Playwright, Puppeteer, Pyppeteer, and Selenium, with examples in Node.js, Python, Java, and VB.NET. The API itself is language-agnostic REST.
What happens to my profiles if my subscription expires?
They stay in your account for 6 months. If you do not renew within that window, all profiles are deleted. Downgrading to a cheaper tier is only possible after the current subscription ends.
Final Thoughts
Octo Browser is the right call when fingerprint quality matters more than a low entry price, and when you need a real API rather than a no-code builder. It costs more than most alternatives and includes no proxy traffic, so budget for both. The browser handles the device layer and the proxy handles the network layer, and platforms link accounts by IP before they ever look at a fingerprint. Pair each profile with a sticky residential IP and the setup holds.
