Nstbrowser Alternative: Kameleo vs Send.win Compared

Why Look for an Nstbrowser Alternative?

The right nstbrowser alternative depends on what you actually run. If you scrape headlessly at volume, Nstbrowser’s pay-per-launch cloud model still holds up. If you keep a fixed set of seller, ad or social accounts alive, per-launch metering is the wrong cost structure: Kameleo bills by concurrent browser, and Send.win charges a flat monthly fee with residential proxies included and no launch cap on local profiles. This comparison covers the features, the strengths and the line items most lists skip.

Nstbrowser vs Kameleo vs Send.win at a Glance

Read the row that matches your workload, not the largest profile number. Nstbrowser meters usage, Kameleo meters simultaneous browsers, and Send.win sells plan tiers with proxy traffic attached.

One clarification before the numbers: stored profiles are library entries, not concurrent sessions. Nstbrowser’s 500,000 profiles on Scale matter if you maintain a huge archive. They do not mean 500,000 browsers running at once.

What Nstbrowser Gets Right

Separate the two products first. Nstbrowser ships a desktop anti-detect browser for profile management and a headless cloud automation service for scraping. Many alternative roundups compare only the first and then price the second, which is how one tool gets described as both cheap and expensive.

Two Products, Two Price Tags

The cloud scraping stack sits in the $299–$599 per month bracket according to a July 2026 review — roughly ten times a desktop-only plan — because you rent remote browsers and orchestration rather than seats. The $29.9 Starter tier and that bracket are both real. They pay for different halves of the platform.

Standard and Once Profiles Fit Real Workflows

Standard profiles keep cookies, login sessions, fingerprints and local data across launches. Once profiles wipe everything at session end, which is what you want for one-off scraping runs. You can point a scraper at a Once profile without disturbing the fingerprint history of an account you sell from.

A Cookie Collector That Saves Rework

The built-in cookie collector captures, categorizes and validates session, persistent, secure and third-party cookies, stores them encrypted and syncs them per profile. When you rebuild sessions after a migration, that is the feature you notice missing first.

Support Depth and a Self-Hosted Path

Nstbrowser advertises a 150+ person technical support operation running 24/7, which matters when scraping is production work. The platform is closed source, but you can self-host the runtime through Docker alongside the hosted API and desktop client. Self-hosting changes where the browser runs, not what you can inspect — the fingerprinting engine stays proprietary.

What Nstbrowser does best is raw stored profile counts, from 500 on the free tier to 500,000 on Scale. That is why it keeps appearing in roundups of browsers with unlimited profiles — but a stored profile you never launch costs nothing and earns nothing either.

Where Nstbrowser’s Billing Model Starts to Hurt

Daily Launch Caps Are the Real Ceiling

The free tier allows 30 standard launches a day. Paid tiers list 3,000, 20,000 and 50,000 launches on Starter, Growth and Scale. Open 40 profiles four times a day and you need 160 launches daily, so the free tier is out before lunch and Starter’s allowance becomes the number you plan around.

Overage Is On by Default

You are not stopped at the quota; you are billed. Standard launches cost $0.015 each on Free and $0.008–$0.01 on paid tiers, while Once-profile launches run $0.004–$0.008. A runaway automation loop at Growth rates becomes a four-figure line item before anyone checks the billing page.

CAPTCHA Solving and Proxy Traffic Bill Separately

Every plan bundles only 1–2 GB per month across residential, IPv6 and datacenter traffic. Beyond that, residential overage runs $1.5–$1.8 per GB and static ISP is $2.5 per IP. CAPTCHA solving is billed per 1,000 requests across reCAPTCHA v2/v3, Enterprise, Text, AWS and Cloudflare Turnstile — around $1 per 1,000 at the highest volume tier and $1.60–$3.80 per 1,000 on Free. None of it sits inside the plan price.

Public Pricing Numbers Conflict

One June 2026 review corrected the widely circulated $29/month figure as a typo for a $299 Professional tier, while the official page currently lists Starter at $29.9 — so treat third-party tables as indicative only. A July 2026 review also noted that several cells in Nstbrowser’s public pricing table render as placeholders, which means per-tier figures copied from blogs may not match checkout. Verify the tier on the day you subscribe.

Fingerprint Consistency: What Public Tests Show

Detection tests are a snapshot, not a verdict, but they are the only public evidence. In an October 2026 retest run by a competing browser vendor across Pixelscan, Iphey and CreepJS, NstBrowser launched with a median 4.7 seconds on Chrome 149 and passed Pixelscan, then scored 30 — “Unreliable” — on Iphey. Across the field, 7 of the 11 browsers that launched failed Iphey; only Gologin, Octo Browser and Hidemium passed all three checkers. Kameleo did not start on the test machine and went untested in that round.

Treat those results as directional: one machine, one day, one Chrome build. Several reviewers publishing such tables sell an alternative browser, which makes the framing suspect even when the numbers hold. If you want to understand how a checker decides a profile looks automated rather than chase a score, read up on Fingerprint.com detection tests — coherence between canvas, WebGL, fonts and hardware matters more than any single value.

Feature by Feature: Profiles, Proxies, Teamwork, Mobile

Profile model and where data lives

Nstbrowser keeps fingerprints and cookies on its side and syncs them per profile — the cookie collector is explicitly encrypted and cloud-stored. Sendwin Browser keeps your profiles on your machine, with optional cloud sync that follows you across devices: 20 profiles on Pro and 100 on Team. That distinction matters when two people work the same accounts from different laptops.

Proxy handling

Nstbrowser sells its own IPs from $0.4/GB for IPv6 across residential, IPv6, datacenter and ISP, assignable per profile inside the platform, and bring-your-own still works. Kameleo bundles no traffic, so your proxy bill sits outside both the subscription and its UI. Send.win includes residential proxies on every plan and pins timezone, locale, WebRTC and geolocation to the exit IP automatically, so a profile never claims Frankfurt time while exiting through Dallas. That coherence is also what keeps you clear of how sites flag a proxy IP.

Teamwork and seats

Nstbrowser gives the free tier 3 members and scales to 100 on Scale, yet a June 2026 review scored its team collaboration 5/10 against 8/10 for automation. Seat count and shared workflow are different things. Send.win hands a paid teammate a shared profile that opens already signed in — no password changes hands — supports live cloud sessions for up to 20 paid members on Pro and 50 on Team, and includes 6 and 16 team seats respectively. On Team you can also block or redirect pages inside shared sessions.

Mobile fingerprints

Nstbrowser is Chrome-only with no mobile profile type. Kameleo covers Android emulation through a mobile app, Gologin ships a native Android app synced to the desktop, Octo Browser has iOS and Android apps, and Hidemyacc offers mobile fingerprints. If your accounts live in mobile-only apps, that single gap decides the switch.

Automation: Porting Puppeteer, Playwright or Selenium Scripts

Nstbrowser works with Puppeteer, Playwright and Selenium and handles Cloudflare and Turnstile challenges, but it returns no parsed data — selectors, pagination and retries stay your problem. Kameleo exposes a REST API with published rate limits of 60 to 1,200 requests per minute depending on tier.

Moving to a local anti-detect browser is mostly a connection-layer change. Keep your selectors and page logic; swap how the driver attaches. With Playwright, you connect over CDP to the profile’s own endpoint:

from playwright.sync_api import sync_playwright

# Copy this URL from the profile's automation settings in Sendwin Browser.
# Each profile exposes its own local endpoint - never guess the port.
CDP_URL = "http://127.0.0.1:PORT"  # copy it from the profile's automation settings

with sync_playwright() as p:
    browser = p.chromium.connect_over_cdp(CDP_URL)

    # Reuse the profile's existing context when one exists
    context = browser.contexts[0] if browser.contexts else browser.new_context()
    page = context.pages[0] if context.pages else context.new_page()

    page.goto("https://example.com/login", wait_until="domcontentloaded")
    print(page.title())

    browser.close()  # disconnects automation; the profile keeps its cookies

Puppeteer and Selenium attach the same way through their CDP options, and everything above the connection line stays as it is. One constraint to budget for: the local Automation API is a Team feature on Send.win — it is not available on Free or Pro — so plan for $49/month if scripting is core to your workflow.

What You Pay Each Month, by Workload

The two metered models behave very differently at the same workload. Below is list-price arithmetic for four common shapes, before proxy traffic and CAPTCHA solving.

Add-ons sit on top for two of the three. Nstbrowser charges per extra launch, per 1,000 CAPTCHA solves and per GB of proxy overage; Send.win charges $6 per extra GB and $0.05 per extra profile, with 5 GB included on Pro and 20 GB on Team. Kameleo’s add-on is simply the next concurrency tier.

The wider field, priced

If you want more options: Multilogin is enterprise-grade with 5 free profiles, 200 MB of proxy and 30 mobile minutes, and its Pro plan listed at $149/year. Gologin starts free with 3 profiles and paid plans from $9/month, or $4.50/month billed yearly for 10 profiles. Hidemyacc gives a 7-day trial with 30 profiles and monthly plans from $10. Incogniton offers 10 free profiles for two months, then 3, at $13.99/month billed every six months. Dolphin Anty gives 5 free profiles and $10/month for 20. Octo Browser has no free tier — just a 2-day trial — then EUR 10/month or EUR 7/month yearly for 3 profiles.

Whichever you shortlist, per-GB proxy math is where budgets quietly break, and it is worth comparing residential proxy prices before you sign a twelve-month term.

Which Alternative Should You Pick?

• Headless scraping at volume: stay on Nstbrowser or move to another cloud automation service. You are paying for remote execution, CAPTCHA handling and rate, so cap your automation loops and check the billing page weekly for the first month.
• 50–500 accounts that stay logged in: flat pricing wins. Send.win Pro covers 150 profiles, 20 residential proxies and 5 GB for $19/month with no launch metering, and Team adds 500 profiles, 20 GB and the local automation API.
• Agencies with teammates: compare collaboration, not seat counts. Nstbrowser scales to 100 members but scored 5/10 on collaboration, while Send.win sharing is paid-to-paid and opens a profile already signed in.
• Mobile-only accounts: Nstbrowser cannot serve you. Look at Kameleo, Gologin, Octo Browser or Hidemyacc, and accept that a mobile workflow usually sits beside your desktop one.

Pros and Cons

Nstbrowser

• Pro: Automation is its strongest area — 8/10 for API work in a June 2026 review — with a self-hosted Docker option.
• Pro: Standard and Once profile types, plus a cookie collector that validates and encrypts sessions per profile.
• Con: Per-launch, per-CAPTCHA and per-GB charges stack on top of a plan you already pay for, and overage is on by default.
• Con: No downgrades, auto-renewal on a linked card, Chrome-only, and public pricing that contradicts itself on both price and launch caps.

Kameleo

• Pro: Concurrency pricing is predictable if you know your peak simultaneous load, and it bills nothing per launch.
• Pro: Android emulation through a mobile app covers a gap Nstbrowser leaves open.
• Con: No bundled proxy traffic, so you source and manage IPs yourself.
• Con: EUR 59 for 10 concurrent browsers costs more than Nstbrowser Starter before proxies, and it failed to start in the October 2026 test round.

Send.win

• Pro: Flat pricing with residential proxies on every plan, no launch metering and no concurrency cap on local profiles.
• Pro: Fingerprints spoofed at the engine level and kept coherent, with timezone, locale and WebRTC following the proxy exit IP automatically.
• Con: The local Automation API is Team-only, so automation-first buyers pay $49/month rather than $19.
• Con: 150 profiles on Pro is less headroom than Nstbrowser’s stored-profile counts, and extras cost $0.05 each.

Frequently Asked Questions

Is Nstbrowser free, and how many profiles does it include?

The free tier includes 500 stored profiles, 30 standard launches per day and 3 team members. The launch cap is the real limit — profile storage is generous, but 30 launches a day covers only a handful of active accounts. Nstbrowser’s homepage advertises up to 1,000 daily launches, which conflicts with its own pricing page.

What is the best Nstbrowser alternative for multi-account management?

For keeping accounts logged in, Send.win fits best because pricing is flat and proxies are included from the trial. For concurrency-heavy parallel work, Kameleo’s tiers are easy to budget. For pure headless scraping, staying on Nstbrowser or moving to a cloud automation service makes more sense than switching to a desktop browser.

Does Nstbrowser include proxies, or do I need to buy them separately?

Paid plans bundle 1–2 GB per month across residential, IPv6 and datacenter traffic, and built-in proxies sell from $0.4/GB for IPv6, assignable per profile. Once the allowance runs out you pay overage, around $1.5–$1.8 per GB for residential and $2.5 per static ISP IP. Bring-your-own proxies are still supported.

Can I automate Nstbrowser with Puppeteer or Playwright?

Yes. Nstbrowser works with Puppeteer, Playwright and Selenium and handles Cloudflare and Turnstile challenges, but it returns no parsed data, so you keep writing selectors and extraction logic. If you move to Send.win, the same scripts attach over CDP, though the local Automation API requires the Team plan.

How does Nstbrowser’s launch-quota pricing compare to Kameleo?

They measure different things, so a direct comparison misleads. Nstbrowser charges $0.004–$0.015 per launch beyond your allowance, on top of stored profiles. Kameleo charges per concurrent browser regardless of how often you launch — EUR 59 for 10 at once, EUR 299 for 100. High launch volume favours Nstbrowser; long sessions favour Kameleo.

Is Nstbrowser open source, and can I self-host it?

It is closed source, but a self-hosted Docker deployment runs alongside the hosted cloud API and desktop client. Self-hosting changes where the browser runs, not what you can inspect — the fingerprinting engine stays proprietary either way. If source auditing is a requirement, most commercial anti-detect browsers will not satisfy it.

Can I downgrade my Nstbrowser plan mid-cycle?

No. Upgrades are supported — you pay the difference and the change applies immediately — but downgrades are not offered. Auto-renewal runs off a linked card unless you disable it under Billing → Current Period, and unpaid invoices block service. Plan for peak load, then reduce launches rather than the tier.

How much does CAPTCHA solving add to an Nstbrowser bill?

It is billed per 1,000 requests on top of the plan, covering reCAPTCHA v2, v3, Enterprise, Text, AWS and Cloudflare Turnstile. Listed rates run from roughly $1 per 1,000 at the highest volume tier up to $1.60–$3.80 per 1,000 on Free. At 20,000 solves a month, that is $20–$76 added to your plan at those rates.
