Choosing an antidetect browser

Every product in this category claims the same four things: unique fingerprints, isolated profiles, proxy per profile, automation. The claims are mostly true and mostly identical, which is why comparing feature lists tells you almost nothing. Here is what actually differs.

Cost per profile, not price per plan

Plan prices are not comparable because the plans hold different numbers of profiles. Divide the monthly price by the profile count and the products separate immediately — the same money buys three or four times as many profiles in one place as another, and the headline figures do not show it.

Watch the step between tiers too. A plan that looks cheap at ten profiles can cost more than a competitor's mid tier the moment you need fifty.

Coherence, not uniqueness

Any tool can randomise a fingerprint. Randomised values are what gets a profile flagged: a Windows user agent reporting a Mac GPU, a timezone that contradicts the proxy's country, a screen size no real device ships. Detection does not look for a fingerprint it has seen before; it looks for one that disagrees with itself.

So the question to ask is not "are the fingerprints unique" but "are they consistent". That is covered properly in browser fingerprinting explained.

Whether proxies are counted

Some products meter proxies separately from profiles, or sell bandwidth. Check whether binding a proxy to every profile costs extra, and whether the profile's timezone and locale follow the proxy automatically or have to be set by hand — getting that wrong by hand is one of the more common ways a profile gives itself away. See residential vs datacenter proxies for which type to bind.

Automation you can actually use

Two different things travel under this name. A no-code builder matters if you want to record a repetitive task and run it across many profiles. A local API matters if you already write Puppeteer or Playwright and want to drive a profile from your own code. Products differ on whether they offer one, both, or a token version of either — and on whether the API is included or gated behind the top tier. Ours is documented at the local automation API.

A third thing is starting to appear: letting an AI assistant drive a profile directly, rather than you writing the script. What matters there is whether the assistant gets the profile’s real session — its fingerprint, proxy and logins — or is handed a bare browser and left to manage credentials itself. Ours is documented at AI assistant (MCP).

Team access

If more than one person touches the accounts, look at how members are priced and how granular the permissions are. Two questions separate the serious implementations: can you grant access to some profiles rather than all of them, and does removing a person leave their work in place? See team members in Parallel for how we answer both.

What happens when you delete one

A profile is not a row in a spreadsheet. Its fingerprint cannot be regenerated — a new one is a different computer as far as every account it is signed into is concerned — and its cookies may be the only copy of a login in existence. So the question is not whether a tool has a delete button, it is what that button does.

Ask whether deleted profiles are recoverable, for how long, and whether that recovery is part of the paid plan. A recycle bin that only paying accounts get means a free user’s misclick is permanent, which is a strange thing to charge for. Ask too whether the browser data is really deleted when it is finally purged — several tools leave the profile folder on disk forever, so a machine slowly fills with the remains of profiles nobody has.

Whether the account itself is protected

Once profiles sync, your login to the tool is worth more than the tool. It holds the browser sessions for every account you run, which means one guessed password is not "somebody read my email" — it is every account you operate, at once.

Look for two-factor authentication that is available on every plan rather than sold as a business feature, an email when the account is opened from somewhere it has not been seen before, and a record of who changed what if more than one person has access. Then ask the less obvious question: are your saved passwords part of what syncs? They should not be. Ours are encrypted by the operating system’s own keychain and never leave the machine; session cookies do sync, encrypted with a key our servers never hold in plaintext.

Test it rather than trusting anyone

Every vendor on this subject, including us, has an interest in the answer. The free tiers exist precisely so you do not have to take anyone's word: create one profile, bind a proxy, and run it through our fingerprint test — which works on any browser, not just ours. If a tool's output contradicts itself there, no feature list matters.

Individual comparisons

• Parallel as an AdsPower alternative — price, profile counts, team seats, and when AdsPower is still the better choice.
• Parallel as a GoLogin alternative — where each one is cheaper, why team seats usually decide it, and the platform difference that settles it first.
