About Nstbrowser

Nstbrowser is an antidetect browser for Windows and macOS with a cloud browser and Docker images for automation, run by NST LABS TECH LTD; the site doesn't state the company's country. Profiles run on nstchrome, the company's own Chromium kernel, with fingerprints based on real users' fingerprints, the company states. The desktop kernel version isn't published and the release notes page on the site stops in October 2024; the official Docker image shipped nstchrome 153 on October 14, 2026.

Plans limit launches a day rather than profiles. The free plan has 500 profiles, 30 launches a day and 3 team members with the API and AI agent included, and extra launches cost $0.01 each. Starter costs $29.90 a month for 20,000 profiles, 3,000 launches a day and 20 members, Growth $49.90 and Scale $89.90 raise those limits, and annual billing takes 40% off, so Starter costs $17.93 a month. Developer plans for cloud and Docker use start at $89.90. Subscriptions are paid by card or PayPal.

Automation runs through a REST API with Node.js and Python SDKs for Puppeteer, Playwright and Selenium, an RPA module with a marketplace, an AI agent and Browserless cloud sessions. Teams use custom permission groups by menu and profile group. Older documentation describes Android and iOS emulation in profiles; there are no cloud phones or mobile apps. Nstbrowser's affiliate program pays 15% of referred subscriptions for 24 months.

Nstbrowser: our review

Nstbrowser gives 500 free profiles but caps them at 30 launches a day; 3,000 launches cost $29.90 a month. The API and an AI agent come free. The catch: it doesn't publish its desktop kernel, its Docker image runs Chromium 153, and its terms ban fake accounts.

Nstbrowser has the biggest free plan among antidetect browsers: 500 profiles, 3 team members, and the API and an AI agent included. The number that matters is a different one: 30 launches a day. Nstbrowser prices its plans by how often you open profiles, not by how many you keep, so the free plan fits 30 accounts opened once a day, and 3,000 launches a day cost $29.90 a month.

This review is built on what Nstbrowser publishes: its pricing page, documentation, terms, download page, its Docker images and its GitHub, all checked on October 22 and 23, 2026. For how its engine situation compares with Dolphin, AdsPower, Octo and GoLogin, see Antidetect Browsers for Media Buyers 2026: Real Differences.

What is Nstbrowser, and who makes it?

An antidetect browser and a cloud browser for developers in one product. The desktop client runs on 64-bit Windows 10 and later and on macOS, Intel and Apple Silicon; the download page lists version 1.23.2. There's no Linux desktop client. On Linux, Nstbrowser runs only as a headless agent for Ubuntu 22.04 and 24.04 servers, managed from the command line.

The company is hard to pin down. The site footer says NST LABS TECH LTD, the terms are written for Nstbrowser LLC under United States law, and neither page gives a country of registration or an address.

The site sells scraping first. The home page leads with web scraping, Cloudflare bypass, a web unblocker and CAPTCHA solving, and only then with multi-account management. That tells you who the paid plans are designed for, and it explains the pricing model below.

Launches, not profiles: how Nstbrowser plans work

Every plan counts profile launches a day. A Standard Profile is the usual antidetect profile: it keeps cookies, logins, the fingerprint and local data between launches. A Once Profile is a fresh browser for one session that wipes everything when it closes, which suits scraping, not accounts.

For accounts, the free plan means 30 opens a day. That's 30 accounts opened once, or 10 accounts opened 3 times. Above the limit you don't get blocked: each extra Standard launch costs $0.01 and goes to an invoice, paid from prepaid credits at $1 per credit.

Run the math before you stay free. A buyer with 100 accounts who opens each one 3 times a day makes 300 launches. On the free plan that's 270 extra launches, $2.70 a day or about $81 a month. Starter costs $29.90 for 3,000 launches a day, or $17.93 a month on yearly billing, so past about 100 extra launches a day the paid plan is cheaper.

One quirk: extra launches cost $0.015 on Starter, more than the $0.01 on Free, falling to $0.008 on Scale. Starter's 3,000 launches a day cover most solo buyers, so few will hit it.

Ignore the home page's free plan. It still promises an "unlimited-time Free Professional subscription" with up to 1,000 launches a day and unlimited profiles and members. The pricing page, which is what you get, says 500 profiles, 30 launches and 3 members.

Which kernel is Nstbrowser running?

Nstbrowser runs its own Chromium build called nstchrome, and doesn't say which version the desktop client ships. The release notes page on the site stops at version 1.12.0 from October 23, 2024; the last kernel it names is nstchrome 128, from August 2024. Releases continued: Nstbrowser's agent on GitHub reached 1.23.2 on September 28, 2026, the same number the download page lists, but the releases say nothing about the kernel. The documentation says the client shows the kernel version in Settings, under Account and Version.

The only public number is the Docker image. Nstbrowser's official browserless image moved to nstchrome 153 on October 14, 2026, when Chrome 155 had been out for a week. Chrome 156 came out on October 20, so the image is now 3 versions behind. Its history shows the pace: 140 in September 2025, 143 in December, 146 in March 2026, 149 in June and 153 in October. That's a new kernel about every 3 months, while Chrome ships every 2 weeks.

Why it matters. A profile that claims an old Chrome stands out to the sites you log into. The desktop client may run a newer kernel than the Docker image, but nobody publishes it, so open Settings in the client and compare the number with the current Chrome version before you move accounts in.

How Nstbrowser handles fingerprints and profiles

It doesn't explain the method. Nstbrowser says it creates "authentic browser fingerprints based on users' real fingerprints." We found no published analysis of its fingerprints by a detection company or researchers, so judge it on your own checks.

Desktop profiles may be Windows only. The documentation says desktop profiles emulate only Windows and mobile ones Android and iOS. The page is undated and other parts of the docs are clearly old, so check in the client whether macOS profiles have appeared since.

The profile tools are practical: cookie import and export in JSON, launch logs and proxy logs for each profile, and up to 10 saved snapshots of a profile you can restore, if you turn on history sync for its group. Your account password is used as the key that encrypts cookies and session data, so pick a strong one and keep it.

Automation, cloud browsers and AI agents

This is where Nstbrowser is strongest, and most of it is free. The API and the AI agent are ticked on every plan, including Free. Scripts connect through the local API with Node.js and Python SDKs, and Puppeteer, Playwright and Selenium drive profiles. A no-code RPA module comes with a marketplace of ready scripts, and a synchronizer repeats your actions across browser windows.

AI Agent Skills let an AI agent drive profiles. Each skill is a folder with instructions the agent loads; Nstbrowser names OpenClaw as the agent runtime and publishes examples for X, Facebook, YouTube and TikTok. Its open-source command-line agent is on GitHub under the Apache 2.0 license. We found no official MCP server.

For developers there's a separate track: Developer plans billed by Once Profile launches, cloud browsers, dedicated servers and a Docker image you can host yourself. Most media buyers won't need it.

Built-in proxies and a CAPTCHA solver

Proxies are sold inside the client. Residential traffic costs $1.80 per GB on Free down to $1.50 on Scale, IPv6 $0.30 to $0.40, datacenter $0.60 to $0.80, and a static ISP address $2.50 per IP. Paid plans include 1 to 2 GB a month of each type. Nstbrowser doesn't name the network behind them, so test the IPs before you trust them with ad accounts.

The CAPTCHA solver is pay per use. The pricing page lists 7 types, priced per 1,000 requests: reCAPTCHA v2 costs $1.60 on Free and $1 on Scale, Cloudflare Turnstile $2 and $1.40. It's built for scraping; for ad accounts it's a detail.

Team work: members included, no per-seat price

Members come with the plan: 3 on Free, 20 on Starter, 50 on Growth and 100 on Scale. There's no price for an extra seat, because the limits are high enough that you don't need one.

Permissions are flexible. The owner builds permission groups with add, read, write and delete rights for each section of the client, and gives members access to specific profile groups. Profiles can be transferred or shared with another team. What we didn't find is a team activity log: the logs are per profile, launches and proxies, not a record of who did what.

Terms that matter for media buyers

Read them before you farm accounts. Nstbrowser's terms list "any form of creating fake accounts or content" and "any form of advertising fraud or click fraud" among prohibited uses. They also allow Nstbrowser to block an account or delete it with all its data, with no compensation, and the same terms rule out refunds.

No refunds, in any form. The terms say so in those words. You can cancel auto-renewal in the dashboard and keep access until the period ends. Upgrades take effect at once for the price difference; downgrades only take effect at the next renewal.

Start on the free plan. Sign up through our link. We have no promo code for Nstbrowser, so there's nothing to enter at checkout.

Payment is by card (Visa, Mastercard, AMEX) through Stripe or by PayPal. Credits pay only for usage over the limits, not for subscriptions. Quarterly billing takes 10% off and yearly 40%.

If you want to refer people yourself, Nstbrowser's affiliate program pays 15% of referred subscriptions for 24 months.

Nstbrowser vs other antidetect browsers

How it compares at about 100 profiles, on monthly billing, October 22, 2026:

  • Nstbrowser. 100 profiles: $0 up to 30 launches a day, then $29.90. 3 people, about 100 profiles: $0 or $29.90. On the free plan: 500 profiles, API, AI agent. Mobile: Android and iOS profiles in the docs. Chromium kernel on October 22: 153 in Docker, desktop not published.
  • AdsPower. 100 profiles: $36. 3 people, about 100 profiles: $46. On the free plan: synchronizer, no API. Mobile: iOS app. Chromium kernel on October 22: 155.
  • MoreLogin. 100 profiles: $35. 3 people, about 100 profiles: $40. On the free plan: API, RPA, synchronizer. Mobile: cloud Android phones. Chromium kernel on October 22: 148 (last published, June).
  • GoLogin. 100 profiles: $39. 3 people, about 100 profiles: $109 (Business). On the free plan: no API. Mobile: Android and iOS apps, Cloud Android. Chromium kernel on October 22: Orbita 153.
  • Multilogin. 100 profiles: $40 (Business). 3 people, about 100 profiles: $40 (unlimited seats). On the free plan: no API. Mobile: cloud Android on real devices. Chromium kernel on October 22: Mimic 155.
  • Dolphin{anty}. 100 profiles: $89. 3 people, about 100 profiles: $109. On the free plan: no API. Mobile: none yet. Chromium kernel on October 22: 155.

Nstbrowser vs AdsPower and MoreLogin. All 3 put a lot on cheap plans, and all 3 cost about $30 to $36 for a working setup. Nstbrowser wins on profiles and seats, which it barely limits; AdsPower publishes a current kernel, Chrome 155; MoreLogin has cloud Android phones. If you open accounts a few times a day, Nstbrowser's Starter is the cheapest of the 3. See our AdsPower review and MoreLogin review.

Nstbrowser vs Dolphin{anty} is price against track record: Dolphin costs 3 times as much for 100 profiles but runs Chromium 155 and is built around ad accounts, not scraping. Our Dolphin{anty} review has the details. For the whole field, see the antidetect browser pricing comparison and the best free antidetect browsers.

Checklist: what to do

Questions about Nstbrowser

Is Nstbrowser free?

Yes. The free plan has 500 profiles, 3 team members, the API and the AI agent, with 30 profile launches a day. Extra launches cost $0.01 each.

How much does Nstbrowser cost?

Starter costs $29.90 a month for 20,000 profiles, 3,000 launches a day and 20 members; Growth $49.90 and Scale $89.90 raise the limits. Yearly billing takes 40% off, so Starter costs $17.93 a month. Developer plans start at $89.90.

Which Chrome version does Nstbrowser use?

Nstbrowser runs nstchrome, its own Chromium build, and doesn't publish the desktop version. Its official Docker image moved to nstchrome 153 on October 14, 2026; Chrome 156 came out on October 20. Check the version in the client's settings.

Is Nstbrowser safe?

We found no reported breaches. The concerns are transparency: the desktop kernel isn't published, the release notes stopped in 2024, the company's country isn't stated, and there's no outside analysis of its fingerprints. The terms also ban fake accounts and rule out refunds.

What is the difference between a Once Profile and a Standard Profile?

A Standard Profile keeps cookies, logins, the fingerprint and local data between launches; that's the one for accounts. A Once Profile is a fresh browser that wipes everything after the session, for scraping and one-off tasks. Once launches are cheaper.

Nstbrowser or AdsPower: which is better?

For many profiles and seats on little money, Nstbrowser: its free plan holds 500 profiles, and $29.90 covers 3,000 launches a day. For a published, current kernel and a product built around ad accounts, AdsPower: 100 profiles for $36 on Chrome 155.

Compare Nstbrowser with other antidetect browsers

—editors’ score / 5

Our verdict on Nstbrowser

A strong free or cheap tool for automation and large profile counts, but check its engine and its terms before you trust it with ad accounts.

Nstbrowser is built for developers and scrapers, and it shows in the good parts: the API, the AI agent, RPA and a synchronizer on the free plan, hundreds of profiles and dozens of seats for $29.90. The pricing by launches is fair once you count your opens. What holds it back for media buyers is transparency: the desktop kernel isn't published, the public changelog stopped in 2024, the only public kernel number is 3 versions behind Chrome, and the terms forbid the fake accounts that account farming produces.

My advice: sign up free through our link, check the nstchrome version in Settings, and run a couple of cheap accounts with your own proxies for a few weeks. If the kernel is current and your accounts hold, Starter is one of the cheapest setups on the market; if it isn't, AdsPower or MoreLogin cost a few dollars more.

Nstbrowser reviews around the web

Public reviews from Trustpilot and G2. Their ratings count toward the users’ score with less weight than member reviews.

  • Branislav Bjelic
    Good anti-detect browser I've had a positive experience with NST Browser so far. The free version is more than enough to test all the core features and determine whether it fits your workflow. One of the biggest advantages is that NST provides a free API key, which is a great benefit for users who want to automate tasks without immediately upgrading to a paid plan. The browser is easy to set up, stable, and offers a solid fingerprint management system. The only downside is the limitation of 30 profile launches in the free plan. For small projects and testing, this is perfectly acceptable, but users managing larger operations will likely need to upgrade to one of the premium plans. Overall, NST Browser offers excellent value for anyone looking to evaluate an anti-detect browser before committing to a paid subscription.

    they don't help they don't help, their services ar crap, don't use them, it's a lot of bugs, you risks your accounts to get banned
  • Ketmani P.
    Profile Management Made Easy, Needs Better Update Automation I like Nstbrowser because it has a generous free plan where I can create as many profiles as I want and launch up to 10 per day. This feature is great because I need many different profiles for the most popular countries that visit us, and it helps me test how localization looks. Additionally, having a bunch of prepared profiles that I can launch with one click is really convenient. It asks too often to refresh the interface to update it (like at least once in a week). I think they can automate it and do it by themselves. The initial setup took a bit of time. It didn't work at first, and after asking support, it turned out I needed to download Chrome core at first to launch it. Nstbrowser lets me create different browser profiles with one click, solving the issue of quickly testing UI in various languages and resolutions.
