Switching From Octo Browser to JustBrowser: 7-Step Migration Guide (2026)

Switching from Octo Browser to JustBrowser doesn't have to trigger account bans or verification loops. Last Tuesday I got a DM from someone running thirty-eight Octo Browser profiles across affiliate networks. Their complaint: Octo's per-profile pricing had crept past $180/month for their setup, and they couldn't justify the math anymore.

The profile count wasn't even growing. The bill was.

Look, I've heard this story maybe a dozen times in the past six months. Octo Browser works fine — solid fingerprint engine, decent detection pass rates. But the per-profile pricing model punishes anyone who scales horizontally. Add ten accounts for a new campaign, watch the invoice climb. Not a bug. The business model.

I migrated away from Octo Browser earlier this year. Thirty-one profiles, mostly Amazon seller accounts and some TikTok Shop storefronts. Every one of them made it to JustBrowser without a ban, without a verification prompt, without drama.

Here's exactly how I did it.

What You'll Have at the End

A repeatable migration workflow. Cookies exported from Octo Browser. Proxies rebound in JustBrowser. Fingerprints validated on CreepJS and Pixelscan before you touch anything that generates revenue.

Budget 15-20 minutes per high-value profile. Not instant. But you only do it once, and honestly? The flat pricing on the other side makes it worth the afternoon of careful work. (I say this as someone who'd rather be doing literally anything else.)

Prerequisites

Before starting your Octo Browser to JustBrowser migration:

Octo Browser installed with active profiles you're migrating
JustBrowser downloaded — 7-day trial gives 5 profiles for testing (see the full JustBrowser blog for setup guides)
Cookie export extension installed in Octo (EditThisCookie or Cookie-Editor)
Proxy credentials documented — host, port, username, password for each profile
60-90 minutes for your first batch of 3-5 profiles

Moving more than 10 profiles? Grab JustBrowser Pro ($9.99/mo for unlimited profiles) before you start. Running the trial clock out mid-migration is annoying.

Step 1: Document Everything in Octo Browser First

You want to jump straight to exporting cookies. I get it. Don't.

Open Octo Browser and build a migration spreadsheet. For each profile:

Profile Name	Platform	Proxy Type	Proxy Host	Timezone	Last Active	Priority
AMZ-Seller-03	Amazon Seller	ISP	iproyal.com:30555	America/Chicago	2026-07-08	Critical
TT-Shop-Main	TikTok Shop	Residential	us.oxylabs.io:10001	America/Los_Angeles	2026-07-09	High
TEST-EU-01	General	Datacenter	185.xxx.xxx.xxx:8080	Europe/Berlin	2026-06-28	Low

Why the boring spreadsheet? Because proxy IP consistency matters more than anything else.

If your Amazon seller account has logged in from the same IPRoyal ISP proxy in Chicago for nine months, and you accidentally configure a different provider or region in JustBrowser — you've created a location anomaly. Our timezone and geolocation guide covers what detection systems actually flag.

The tedious documentation saves you from the expensive mistake. I learned this after spending two hours debugging a "suspicious activity" warning that turned out to be a fat-fingered port number. Not fun.

Step 2: Export Cookies from Octo Browser

Octo Browser doesn't have a universal "export all cookies" button. You'll extract per-profile. Yeah, it's tedious.

Method A: Browser extension (recommended for most people)

Open the Octo Browser profile you're migrating
Navigate to the platform — Amazon, TikTok, Facebook, wherever
Confirm you're logged in. Stale sessions export worthless cookies.
Click EditThisCookie → Export → Netscape format or JSON
Save the file: amz-seller-03-cookies.json

Method B: Octo Browser's local API

Octo runs a local API. If you're comfortable with curl (and honestly, if you're not, Method A is fine — I'm not gatekeeping here):

# Start browser with specific profile
curl "http://localhost:50325/api/profiles/{profile_id}/start"

# Connect via CDP to extract cookies programmatically

The API approach is faster for bulk migrations but requires scripting. Most people just use the extension.

Critical part: Export cookies while actively logged in. If your last session was two weeks ago, open the profile, verify you're authenticated, then export. Server-side sessions expire. Old cookie files are useless.

For each profile you should now have: a cookie file + proxy credentials + documented settings.

Step 3: Create Matching Profiles in JustBrowser

Open JustBrowser. Create a new profile. This is where precision matters.

Settings that MUST match your Octo Browser profile:

Operating System: Windows 11 in Octo → Windows 11 in JustBrowser. macOS stays macOS.
Timezone: Must match proxy location. Chicago proxy = America/Chicago. Period.
Language: Must match proxy location. US proxy = en-US primary.
Screen Resolution: Match exactly. 1920x1080 → 1920x1080.

Settings that can differ:

Canvas hash — different engines produce different hashes. Expected.
WebGL renderer — will regenerate. Fine.
Audio fingerprint — same deal.

Here's my honest take — and plenty of people disagree: fingerprint paranoia is mostly overblown during migration. Most people stress over canvas hashes when they should be triple-checking proxy configs. I've probably lost hours of my life arguing about this in Telegram groups.

Platforms weight IP + timezone consistency far more heavily than hardware fingerprint values. Browsers legitimately change fingerprints when users update, reinstall, or switch machines. What doesn't change is your network location pattern.

(I've argued this in too many Discord threads to count. Still my hill.)

Proxy configuration:

Enter your existing proxy credentials exactly. Same host, same port, same auth.

JustBrowser has a built-in proxy tester. Use it. If the returned IP or country differs from what you expect — stop. Debug before continuing.

I watched someone type a port number wrong and burn a $30K/year Amazon seller account. One wrong digit. Check every field, then check again. Annoying? Absolutely. But cheaper than explaining to a client why their account got suspended. (Ask me how I know.)

In JustBrowser's profile settings, find the cookie import option. Paste JSON directly or upload the Netscape format file.

After importing: launch the profile, navigate to the platform, check if you're logged in.

Logged in? Move to fingerprint validation.

Logged out? Something broke. Common causes:

Expired cookies — Session died server-side. You'll need to log back in.
Format mismatch — Strip to essential fields: name, value, domain, path, expiration. Some Octo exports include extra metadata that breaks import.
Domain mismatch — Cookies for .amazon.com don't work on amazon.de.

Re-logging isn't catastrophic. IP and timezone match your historical pattern? One "new device" login looks like... a new device. Normal human behavior. Have 2FA recovery codes ready. The cookie isolation guide covers session handling in more detail.

Step 5: Validate Fingerprints on CreepJS Before Production Use

Do not skip this.

I skipped it once on a "low priority" test profile. Turned out that profile had a linked PayPal business account. The fingerprint inconsistency triggered a manual review. Lesson learned — I still cringe thinking about it.

Before using any migrated profile on an account that generates revenue:

Launch the profile in JustBrowser
Navigate to CreepJS
Wait for the full report (10-15 seconds)
Check the Lies section — should be empty or minimal
Note the Trust Score — aim for 80%+

What you're looking for:

Lies section: Empty is ideal. Red entries = detectable inconsistencies between spoofed values.
Trust Score: 80%+ is solid. Below 65% = misconfigured profile.
Consistency: Run the test twice. Same hashes both times? Good. Values changing randomly = stability issue.

Also run Pixelscan and BrowserLeaks. The CreepJS walkthrough explains what each metric means.

If something fails: check timezone vs proxy location first (causes 60% of issues), then language settings, then OS/browser consistency.

Step 6: Warm Up the Migrated Profile

Your cookies carry session state. But account-age signals extend beyond cookies.

JustBrowser includes a cookie warm-up engine that visits 127 curated sites to build browsing history. Run it on migrated profiles — takes maybe five minutes and reinforces the profile's age signals.

For the first 48-72 hours post-migration:

Keep activity patterns consistent with previous behavior
Don't suddenly run 10x more actions than usual
Avoid heavy automation until you've confirmed stability

If you're using Playwright or Puppeteer for automation, the antidetect REST API guide covers programmatic profile launch.

Step 7: Migrate in Batches, Not All at Once

Don't migrate your most valuable profile first.

I've told maybe forty people this. At least fifteen of them ignored me. Guess which ones regretted it.

Pick 2-3 profiles that matter but aren't critical. Run them in JustBrowser for a full week with normal activity. Watch for:

Unusual CAPTCHA frequency
Verification prompts you didn't get before
Session instability

No issues after a week? Migrate the rest. Problems? Debug before touching high-value accounts.

Common Errors and Fixes

Cookies imported but session is gone

Cause: Cookies expired server-side, or you exported while logged out.

Fix: Log back into the account from the JustBrowser profile. As long as IP + timezone match your historical pattern, one new-device login is normal. Have 2FA recovery codes ready.

Proxy connection fails

Cause: Credentials wrong, or your proxy provider requires IP whitelisting.

Fix: Double-check every field. Some providers (Bright Data, Oxylabs, IPRoyal) require you to whitelist your machine's IP. If you're on a different machine than you used with Octo Browser, add the new machine's IP to your provider's allowlist. The ISP proxy tutorial covers provider-specific setup.

CreepJS trust score dropped vs Octo Browser

Cause: Fingerprint settings don't match proxy location, or there's an OS/language inconsistency.

Fix: Verify timezone = proxy timezone, language = proxy country language, OS = consistent with profile history. Disable all browser extensions during testing — some extensions modify fingerprint APIs in detectable ways.

Profile performance feels sluggish

Cause: Usually proxy latency, not the browser.

Fix: Test proxy speed independently. Slow proxy = your provider's problem, not JustBrowser's. Check hardware acceleration settings if local rendering feels off.

The Pricing Math

Let me be direct: JustBrowser isn't always cheaper than Octo Browser's entry tier.

Octo Browser's Starter plan charges per profile. Their pricing scales with how many profiles you run. JustBrowser Pro is $9.99/mo (or $99.99/year) for unlimited profiles.

Here's what shifts the math:

Under 10 profiles: Octo's entry tier might be cheaper. Do the comparison.
20+ profiles: JustBrowser usually wins. Flat $9.99/mo regardless of count.
50+ profiles: JustBrowser wins hard. No per-profile scaling.

JustBrowser offers a 7-day trial — unlimited profiles, card required, nothing withheld — so you can test migration before committing. That's how I started. Migrated two throwaway profiles, ran them for ten days, then upgraded.

Run the numbers for your situation. I'm obviously biased, but the spreadsheet doesn't lie.

Next Steps

Once your test profiles run clean for a week:

Batch migrate remaining profiles — Gets faster with practice. 5-10 profiles per hour is realistic.
Run parallel for a month — Keep Octo Browser active until you're confident. Don't rage-cancel.
Set up ongoing fingerprint checks — Detection tools evolve. Monthly CreepJS runs keep you ahead.

For click fraud protection on ad accounts running through your migrated profiles, ClickzProtect monitors for fraudulent clicks — their click fraud detection guide explains what signals to watch. For privacy-respecting analytics across profiles, JustAnalytics handles conversion tracking without third-party cookies. Running outbound sales campaigns through these profiles? VeloCalls integrates call tracking that respects your multi-profile setup.

Migration is tedious. Boring work that requires attention to detail exactly when you want to rush. Nobody enjoys this — I certainly didn't. My first batch took way longer than it should have because I kept second-guessing myself.

But if the per-profile pricing math stopped working for you, and you want local-first profile storage with optional unlimited cloud sync, the switch is worth the afternoon. Take your time. Validate everything.

And seriously — don't migrate your most valuable profile first. I will keep saying this until people stop ignoring me.

Frequently Asked Questions

Can I export Octo Browser profiles directly into JustBrowser?

No direct import path exists. Octo Browser profiles use a proprietary format that doesn't translate. You'll export cookies via browser extension, document proxy credentials separately, then recreate profiles in JustBrowser with matching timezone, language, and proxy settings. Plan 15-20 minutes per profile that matters.

Will switching from Octo Browser to JustBrowser trigger account bans?

Not if you keep IP and timezone consistent. Detection systems weight network-level signals far more than browser fingerprint parameters. Same proxy IP, same timezone, same language — fingerprint changes look like normal browser updates. The danger points: changing IPs, timezone mismatches, or lost cookies forcing re-authentication.

How does JustBrowser pricing compare to Octo Browser's per-profile model?

Octo Browser charges per profile on their Starter tier. JustBrowser Pro is $9.99/month for unlimited profiles — or $99.99/year. If you're running 20+ profiles, JustBrowser usually wins on cost. Run the math for your specific count.

What happens to my automation scripts that use Octo Browser's local API?

JustBrowser exposes a REST API plus CDP endpoints for Playwright, Puppeteer, and Selenium. Your automation logic transfers, but you'll update connection strings and endpoint URLs. The API documentation covers the migration path.
