Requirements and Install Tips
Which is the official URL? How do I confirm it is not a phishing fake?
BitBrowser only has the official bitantidetect.com; the main site, client entry, and docs are all under this domain.
To confirm it is not a fake, type the URL by hand, do not enter from a search ad slot or an unknown link, and beware lookalike domains such as *.com.cn, bitbrowser.ltd, bitsbrowser, and bi-tbrowser. The company has named bt1.xiaowu.group, chrome.bitsbrowser.cn, bt1.juyu.ltd, and bite1.ahpldw.cn as dangerous counterfeit sites; browsers also flag them red, so close them immediately.
Where can I download the genuine official version without viruses?
Only downloading the client from the official bitantidetect.com is genuine; it is the only safe download source.
Many search results calling themselves official site or official download, such as *.com.cn, bitbrowser.ltd, xiaowu.group, and bitsbrowser.cn, are mostly SEO mirrors or counterfeit sites whose installers may be tampered with or bundled with trojans. The safe approach: type the URL to enter the official site, do not click search ad slots, and if antivirus flags the download, first confirm it really came from the official site before acting. Packages from fake sites are the real high-risk source of malware and account theft.
Is the official download free? Do I have to pay first?
The official BitBrowser download is completely free; no upfront payment is needed.
Downloading and installing the client and registering an account cost nothing, and after signup you directly receive 10 permanent free profiles, enough for beginner testing and small-scale use. You only need to buy a plan (from about 50 RMB per month) when you want more profiles, bulk proxies, RPA automation, or team collaboration. So download free from the official bitantidetect.com with confidence and avoid paid download on copycat sites.
Can Hong Kong access the official site to download directly? Is a VPN needed?
BitBrowser is a mainland product but not region-locked; whether Hong Kong can access the site directly depends on your local network. The company does not require a VPN for Hong Kong, so test it yourself.
We suggest typing the official bitantidetect.com by hand to access the download; if loading is slow or fails, it is usually a local network issue, so change network or node and retry. Distinguish two things: downloading or logging in to the client is one matter, and using a profile to access platforms abroad is another, where you must configure a proxy IP for the profile.
The official site will not open in Taiwan; is it blocked or do I need a proxy?
There is no official information that the site is blocked in Taiwan; failure to open is more likely a local network or DNS issue, so confirm by testing.
First confirm you typed the official bitantidetect.com and not a fake, then try changing network, changing DNS, or switching proxy nodes and retry. BitBrowser has no built-in proxy, so a dead network shows up as not opening. If only the page loads dynamically slowly, refresh more or try another browser.
Downloading the official site in Singapore is slow; is there a mirror or accelerated link?
BitBrowser strongly advises against hunting for mirror download links; those *.com.cn, bitbrowser.ltd, and xiaowu.group in search are unsafe.
The right approach for slow downloads in Singapore: stick to the official bitantidetect.com, change network or proxy nodes, avoid peak hours, and use a multi-threaded download tool to speed up. Safety always outweighs a little speed.
Frequently Asked Questions
How do I download BitBrowser in Malaysia? Can the official site be accessed normally there?
Malaysian users simply type the official bitantidetect.com to download the client; the product is not region-locked, so choose the Windows or Mac version per your system. Whether the site is accessible in Malaysia depends on the local network, with no official statement, so test it; if loading is slow or fails, it is usually a network issue, so change network or node and retry. Be sure to download from the official site and avoid counterfeit mirrors such as *.com.cn and bitbrowser.ltd in search results, to avoid getting a malware-laden package.
Are the BitBrowser official site and BitBrowser fingerprint browser the same? How do I avoid a copycat?
They are the same product; BitBrowser is the BitBrowser fingerprint browser. The only official site is bitantidetect.com, with the main site, client download entry, and docs all under this domain. Many search results such as *.com.cn, bitbrowser.ltd, bi-tbrowser, and bitbrowers calling themselves official site or official download are counterfeit or mirror sites. The most reliable approach is to type bitantidetect.com directly and not click search ad slots. The company has named several dangerous counterfeit sites, so look for the official mark before downloading.
How do I verify a downloaded BitBrowser installer is not tampered with (MD5 or digital signature)?
The most critical step is the correct source: only download from the official bitantidetect.com. The company has named counterfeit sites such as bt1.xiaowu.group and chrome.bitsbrowser.cn, and packages from them are the most likely to be tampered with and bundled. For verification, on Windows right-click the installer, choose Properties, then the Digital Signatures tab, and check whether the signer is BitBrowser official and the signature is valid; you can also note whether the official package file size looks abnormal. The official page provides no public MD5 value, so bit-by-bit comparison is not possible; rely on the official source plus digital signature verification.
Full BitBrowser download and install guide: how do I install step by step the first time?
Step one: type the official site bitantidetect.com by hand to reach the official download page, choose the Windows or Mac version per your system, and do not download from a search ad slot or a mirror such as *.com.cn. Step two: install after downloading, preferably using the default directory, avoiding Chinese paths, and running as administrator if needed; if antivirus wrongly deletes it, restore from quarantine and add to the whitelist. Step three: open the client and register on the home page, entering username, password, phone (for the code), WeChat or QQ, and email, with the invite code optional, and tick the agreement; signup grants 10 permanent free profiles. After installing, create a profile, set the proxy, then access the target platform.
BitBrowser stalls or errors mid-install; is the installer corrupt and should I redownload?
Do not rush to conclude the installer is corrupt. The most common root cause is downloading a tampered or bundled installer from a search ad slot or counterfeit mirror; the company has named dangerous counterfeit sites such as bt1.xiaowu.group, chrome.bitsbrowser.cn, bt1.juyu.ltd, and bite1.ahpldw.cn. The right approach is to type the official entry bitantidetect.com and redownload a clean installer. When installing, run as administrator, use the default directory, and avoid paths with Chinese or special characters; antivirus false deletion can also cause mid-install errors, so temporarily whitelist the official install directory and reinstall (provided you confirmed the official download).
BitBrowser shows Cannot verify publisher or is blocked by SmartScreen; how do I continue installing?
Fingerprint browser tools like this change the device fingerprint and are often blocked by Windows SmartScreen or antivirus heuristics. Provided you downloaded from the official entry bitantidetect.com, in the SmartScreen prompt click More info then Run anyway to continue; if Defender quarantines it, go to Windows Security, Virus and threat protection, Protection history or quarantined items to restore, and add the official install directory to Exclusions. Remember: whitelisting must be premised on the genuine official version, otherwise you let a real trojan through; never allow an installer from a counterfeit mirror.
BitBrowser uninstalls incompletely and reinstall still shows the old error; how do I fully clean and reinstall?
When a reinstall still shows the old error, leftover files or processes are usually not cleaned. First end all BitBrowser-related processes in Task Manager (the company once fixed a residual issue where the process could not exit after a window closed), then uninstall properly and manually delete leftover files in the install directory. To reinstall, download the latest version from the official bitantidetect.com, run as administrator, use the default directory, and avoid Chinese or special-character paths. If antivirus earlier deleted some files, remember to whitelist the official directory in the antivirus exclusions. The source material gives no official full-cleanup steps, and deep cleanup such as the registry is general knowledge to confirm by testing.
Is it better to install BitBrowser on the C drive or another drive? Can I change the install path?
BitBrowser usually allows a custom install path, and we suggest a non-system drive (such as D) to ease C drive usage, while avoiding directories with Chinese or special characters, because such paths may cause some Windows programs to start abnormally. Reserve at least 2GB of free disk at install, the default directory is fine, and running as administrator is more stable. Be sure to download the installer from the official bitantidetect.com. Whether the install wizard offers a path-change option refers to the actual interface; confirm by testing.
To use BitBrowser across a team, how do I download and deploy to several computers at once?
To use BitBrowser across a team, each computer downloads and installs the same official client from bitantidetect.com, then the team sub-account and member collaboration feature in a paid plan lets everyone log in with their own sub-account, sharing profiles via cloud sync. The free plan supports only one user; multi-user collaboration and cloud sync are paid features, so first activate a plan with enough members in the client Billing Center (such as 50 windows with 2 staff or 100 windows with 4 staff). Be sure each machine downloads from the official site and does not use a copycat package distributed uniformly.
What are the BitBrowser system requirements? Will my old computer run it?
Per community-aggregated figures: Windows 7 or above, 64-bit (Win10 or 11 recommended), 4GB or more memory suggested, at least 2GB free disk; Mac needs macOS 10.14 (Mojave) or above, choosing the Apple Silicon or Intel version by chip. Note these hard numbers appear mainly on third-party aggregation pages and are not confirmed by official pages, so treat them as reference. The bottleneck is often how many windows you open at once rather than whether it installs; some users report clear lag opening more than 30 windows. An old computer running a few profiles is usually fine, but bulk windows eat memory and performance.
Can BitBrowser still install on Windows 7, or only Win10 and Win11?
Yes, it can install. The system requirement aggregated by mirror sites is Windows 7 or above, 64-bit, with Win10 or 11 recommended; 4GB or more memory and at least 2GB free disk are suggested. Note that these specific numbers appear mainly in third-party or mirror figures, are not directly verified on official pages, and should be treated as reference rather than a hard spec (confirm by testing). In practice it runs more stably and smoothly on Win10 or 11, while an old Win7 machine struggles with multiple windows. Be sure to download from the official entry bitantidetect.com and avoid a bundled installer from search ads or counterfeit mirrors.
What is the BitBrowser minimum memory? Will 8GB freeze when opening multiple profiles?
The suggestion aggregated by mirror sites is 4GB or more memory (this number comes from third-party figures, is not officially confirmed, and is reference only). In practice each browser profile is an independent Chromium instance and is memory-hungry, so an 8GB machine opening multiple profiles may indeed lag. The company has a specific record: opening more than 30 windows at once lags for 5 to 10 seconds, and a queue window-opening parameter was added (interval up to 1 second) to ease concurrency; some users also report severe lag after opening more than 30 windows. We suggest an 8GB machine open only a few profiles at once and close them when done, and upgrade to the latest version over the old one if it lags.
Does BitBrowser have disk and CPU requirements? How many windows can a laptop run smoothly?
The requirement aggregated by mirror sites is at least 2GB free disk and 4GB or more memory (these numbers are third-party figures, not confirmed by official pages, and reference only). There is no clear official CPU threshold, but each profile is an independent Chromium instance that consumes memory and CPU, so more windows mean more load. The official record shows opening over 30 windows lags for 5 to 10 seconds. An ordinary laptop should run only a few windows at once and close them when done; how many you can open depends on your memory and CPU, so a small-memory, few-core machine should open fewer. If it lags, upgrade to the latest version over the old one and use the queue parameter to open windows in line and ease concurrency.
My old Mac is Intel with a low macOS version; which BitBrowser version can I still install?
The Mac version comes in Apple Silicon and Intel editions by chip, so an old Intel machine should download the Intel version. For the system, mirror sites aggregate that it needs macOS 10.14 (Mojave) or above (this number is not confirmed on official pages; confirm by testing). If your system is too old to install, try an earlier client version on the official download page, or upgrade the system to a supported version. After installing, a Damaged or Cannot open prompt is the Gatekeeper mechanism; right-click and choose Open, or in Privacy and Security click Open anyway.
Windows Defender deleted BitBrowser as a virus; how do I restore and whitelist it?
Fingerprint browsers change the device fingerprint and are often flagged by antivirus heuristics, a common trait of such tools. Recovery steps: open Windows Security, Virus and threat protection, Protection history or quarantined items, find the quarantined BitBrowser file and click Restore; then go to Exclusions to whitelist the install directory and avoid deletion again; if needed, temporarily turn off real-time protection and re-enable it after installing. The key premise: you must confirm the installer came from the official bitantidetect.com, because if it was a tampered package from a copycat site or search ad, whitelisting lets a real trojan through.
BitBrowser was blocked and deleted by 360, Huorong, or Tencent Manager; how do I allow it?
Fingerprint browsers modify the device fingerprint and are very often flagged by domestic security software heuristics. General allow method: enter that software quarantine or virus-removal log, find the deleted BitBrowser file and click Restore or Trust, then add the whole BitBrowser install directory to the Trust zone or whitelist to avoid repeated blocking; during install you may temporarily turn off protection and re-enable it after. Key premise: first confirm the installer is from the official bitantidetect.com, because a bundled or tampered package from a counterfeit site or search ad means whitelisting lets the real malware through. (Each security software menu name refers to its actual interface; confirm by testing.)
BitBrowser was falsely reported as a trojan on VirusTotal and flagged red by several engines; is it really infected?
Fingerprint browsers like this change the device fingerprint and are often falsely flagged by antivirus heuristics, so multiple red flags do not mean real infection, provided you downloaded the genuine version from the official bitantidetect.com. The real danger is a tampered, backdoor-bundled installer from search ads, mirror sites, or copycat domains. When quarantined, go to Windows Security, Virus and threat protection, Protection history, restore the file, and add the install directory to the Exclusions whitelist. But if the source is not the official site, take the red flag seriously and do not whitelist rashly (confirm toxicity by testing).
After whitelisting BitBrowser, the next update is deleted by antivirus again; how do I allow it permanently?
Fingerprint browsers change the device fingerprint and are often falsely flagged by antivirus heuristics. Allowing only one version means the changed file after an update is deleted again. It is more stable to whitelist the whole BitBrowser install directory (the folder) in Windows Security, Virus and threat protection, Exclusions, rather than only a single exe, so new files after an update are also whitelisted. The premise must be confirming the software is the genuine version from bitantidetect.com, otherwise whitelisting lets a real trojan through.
Does BitBrowser have a Mac version? Where on the official site do I download the Apple edition?
Yes, BitBrowser has a Mac version. The official download page offers both Windows and Mac versions, so go to the official bitantidetect.com and choose the Mac version by operating system. After installing, if it prompts Damaged or From an unidentified developer and will not open, this is the macOS Gatekeeper security mechanism; hold Control and right-click the icon to choose Open, or go to System Settings, Privacy and Security, and click Open anyway. It is not a problem with the software itself.
Does the BitBrowser Mac version support M1, M2, and M3 chips, or only Intel?
The Mac version usually distinguishes Apple Silicon and Intel editions at download, so choose the one matching your machine (M-series chips choose Apple Silicon). However, the official page does not list details such as exactly which of M1, M2, or M3 is supported or the minimum macOS version; these mostly come from mirror aggregation, so refer to the actual options on the official download page and your own machine testing. We suggest going to the official bitantidetect.com to see the currently offered version options.
