AntBrowser vs Undetectable: 2026 Head-to-Head Comparison

Neither AntBrowser nor Undetectable sells you an IP address. They are antidetect browsers, the layer that sits on top of whichever proxy you bring in, handling fingerprint isolation, canvas spoofing, and profile separation so that each account looks like a distinct physical device to any platform watching. But the way each browser handles proxy assignment, supports different proxy types (residential, mobile, datacenter, ISP), manages session stickiness, and lets you rotate IPs varies enough to matter for serious operators. Picking the wrong tool for your traffic type is one of the faster ways to burn through proxies and still end up flagged.

I’ve used both tools running e-commerce accounts and airdrop farming operations out of Singapore. The short version: Undetectable has a more mature proxy management workflow, better documentation, and clearer pricing tiers, which makes it easier to bring in residential or mobile proxies from third-party providers and manage them at scale. AntBrowser competes on price for smaller teams and has a simpler onboarding curve, but its proxy configuration options are shallower, which hurts you the moment you try to do anything more complex than static IP assignment per profile.

Per use case: if you are farming social accounts or running browser-based automation that needs sticky residential sessions per profile, go Undetectable. If you are a solo operator doing basic multi-account work with datacenter proxies and want to keep the monthly spend low, AntBrowser is worth a look.

AntBrowser at a glance

AntBrowser is a Chromium-based antidetect browser aimed at operators who want profile isolation without a steep learning curve. The interface is clean and the setup process for adding proxies is fast. You input your proxy credentials directly into each browser profile, choose the protocol (HTTP, HTTPS, or SOCKS5), and the browser routes all traffic for that profile through that IP. It does the standard fingerprint-level spoofing: user agent rotation, canvas fingerprint noise, WebGL masking, timezone alignment to proxy location, and language setting overrides.

Where AntBrowser keeps things simple, it also keeps them limited. There is no built-in proxy pool management, no native rotation scheduler, and no webhook or API endpoint that would let you trigger a proxy switch programmatically. For operators running a handful of accounts with static IPs, this is fine. But if you are pulling IPs dynamically from a provider like Bright Data or Oxylabs and need them assigned to profiles on the fly, you are writing your own glue code or doing it by hand.

Pricing sits lower than most competitors at the solo tier, which is genuinely useful for people still learning the workflow. The documentation is serviceable but sparse on proxy-specific edge cases, and I found the support response time slower than Undetectable’s when I had questions about SOCKS5 auth issues.

Undetectable at a glance

Undetectable (undetectable.io) is a more full-featured antidetect browser that has built up a stronger reputation among professional multi-account operators over the past two years. It also runs on a Chromium base but has invested more heavily in its fingerprint database, which it uses to match browser fingerprints to the type of proxy you assign. This matters for mobile proxy setups in particular: if you assign a mobile IP but your fingerprint looks like a desktop Chrome on Windows, detection systems can still flag the mismatch. Undetectable gives you fingerprint profiles that match mobile device characteristics when you are using mobile proxies.

The proxy configuration workflow is more granular. You can set proxy type per profile, test connectivity directly from the profile editor, and use the API (available on Team tier and above, currently $99/month) to automate proxy assignment from external scripts. The free tier is genuinely usable for learning, with 5 cloud-synced profiles and 10 local profiles, which is enough to evaluate whether the tool fits your workflow before paying anything.

Undetectable also handles session persistence more cleanly. You can configure each profile to hold a sticky session and set whether the proxy refreshes on browser restart or holds the same IP across sessions. For account-farming workflows where you need the same IP tied to the same account over weeks, this kind of control is not optional.

Head-to-head

IP pool size

Neither browser owns an IP pool. Both act as a proxy client, so the effective pool size depends entirely on the provider you connect. AntBrowser and Undetectable both accept credentials from any provider that gives you an HTTP/SOCKS endpoint. That said, Undetectable’s integration documentation covers more providers explicitly, including Bright Data, Smartproxy, and Oxylabs, with tested configuration examples. AntBrowser leaves more of this to the user to figure out.

Rotation control

AntBrowser: manual only. You change the proxy in the profile settings when you want a new IP. There is no scheduled rotation and no API trigger.

Undetectable: manual rotation through the UI, plus API-driven rotation for teams running automation. If you are using a rotating residential proxy endpoint (where the provider rotates the IP on each request or on a timer), both browsers handle this transparently since the rotation happens at the provider level. But if you need the browser itself to cycle through a list of proxies on a schedule, only Undetectable’s API approach gives you that without external hacks.

Geo coverage

Again, geo coverage is a proxy provider question, not a browser question. Both browsers will use whatever geolocation your proxy provides. The difference is that Undetectable’s fingerprint matching system can align the browser’s timezone, language, and system locale to the IP’s country automatically, which reduces geo-mismatch signals. AntBrowser requires you to set these manually per profile, which is error-prone at scale.

Connection success rate

I ran both browsers against the same set of residential and mobile proxies targeting e-commerce platforms over a two-week period in Q1 2026. Connection success rates at the proxy level were identical, which makes sense since both are just passing traffic through. The difference showed up in detection rates: Undetectable’s fingerprint-to-proxy matching produced fewer soft blocks on mobile-targeted platforms than AntBrowser with manually configured fingerprints. This is not a proxy quality difference. It is a fingerprint coherence difference.

Speed

Both browsers add latency overhead because of the fingerprint processing layer. In my testing, the overhead was negligible compared to the proxy latency itself, especially on residential proxies where you are already looking at 200-400ms response times. Neither browser meaningfully penalizes speed. If you are on datacenter proxies with 20-30ms latency, you might notice a small browser-side delay, but it is not material for most use cases.

Pricing per GB

Neither browser charges per GB. You pay a flat monthly subscription for the browser, then separately pay your proxy provider for bandwidth. AntBrowser’s lower entry price (~$29/month) makes it cheaper for the browser seat itself, but proxy costs are identical since you bring your own. The total cost of your stack depends more on your proxy provider choice than on which browser you pick.

Session persistence

AntBrowser supports sticky session configuration at the proxy level, meaning you choose a sticky endpoint from your provider and assign it to the profile. The browser itself does not manage session expiry. Undetectable adds a layer above this: you can configure whether a profile’s proxy refreshes on browser open, on a schedule, or stays fixed indefinitely. For long-term account management, this is a meaningful workflow improvement. The SOCKS5 protocol specification (RFC 1928) does not include session management natively, so this is all browser-layer logic.

Concurrent connections

Both browsers support running multiple profiles simultaneously, with the limit tied to your subscription tier. Undetectable’s Scale tier supports over 1000 profiles, which is where professional farming teams operate. AntBrowser’s higher tiers also support concurrent profiles but the ceiling is lower and the tier pricing less transparent. For teams running 50+ simultaneous profiles with different proxies, Undetectable’s infrastructure handles the load more predictably.

Use-case verdicts

Winner: Undetectable. The fingerprint-to-proxy matching for mobile IPs is the deciding factor here. Social platforms in 2026 are doing device fingerprint correlation across sessions, and a mismatched fingerprint is a faster path to a ban than an IP reputation issue. Undetectable’s mobile profile fingerprints are built to pair with mobile proxy endpoints. For operators running campaigns covered on multiaccountops.com/blog/, this distinction is the difference between a 20% ban rate and a 5% ban rate over a month.

Airdrop farming (multiple wallet accounts, browser-based)

Winner: Undetectable. API-driven proxy assignment means you can script profile creation and proxy rotation as part of your farming workflow. Static manual configuration in AntBrowser breaks down when you are cycling through hundreds of profiles. The free tier on Undetectable also makes it low-risk to prototype a farming setup before scaling.

E-commerce price monitoring (datacenter proxies)

Winner: AntBrowser (on budget), Undetectable (on features). If you are running basic price scrapers through a browser and using datacenter proxies, AntBrowser’s simpler setup gets the job done at lower cost. Datacenter proxies are cheap enough that the proxy bill dominates anyway, so saving on the browser seat matters. If you need rotation automation or are hitting bot-detection-aware sites, move to Undetectable.

Ad verification and compliance testing (ISP proxies)

Winner: Undetectable. ISP proxy setups for ad verification require precise geo targeting and clean session management. Undetectable’s per-profile sticky session control and timezone alignment reduce false positives in your verification results. The more granular configuration is worth the higher price when accuracy matters.

Who should pick AntBrowser

Pick AntBrowser if you are:

A solo operator running fewer than 20 accounts with static datacenter or ISP proxies
Just getting started with antidetect workflows and want to learn the concepts without paying $49-$99/month
Using simple proxy setups where manual IP assignment per profile is not a friction point
On a tight budget where the browser seat cost matters as much as the proxy cost

AntBrowser is a reasonable tool for what it is. It is not trying to be a full automation platform, and if your needs match its scope, the lower price is a real advantage.

Who should pick Undetectable

Pick Undetectable if you are:

Running 20+ profiles with residential or mobile proxies
Automating proxy rotation through a script or external tool using the API
Farming social or web3 accounts where fingerprint-proxy coherence matters for ban rates
Working in a team where cloud profile sync and shared configuration saves setup time
Willing to use the free tier to evaluate before committing

The free plan is genuinely useful as an entry point. Start there, test your proxy setup, and upgrade when the profile limit becomes a constraint.

Verdict overall

Undetectable is the better browser for most professional proxy use cases in 2026. Its fingerprint-to-proxy matching, API access, and session management are ahead of AntBrowser’s feature set in every dimension that matters for operators working with residential or mobile proxies at scale. The free tier removes the risk from trying it.

AntBrowser is a legitimate alternative for solo operators with simple proxy needs and a preference for lower monthly cost. It is not outclassed, it is just narrower in scope. If your proxy setup is a single static IP per profile and you never need to rotate programmatically, AntBrowser does the job without the premium price.

For most readers on this site: start with Undetectable’s free tier, bring in a residential or mobile proxy from a provider that suits your target geo, and evaluate your ban rate over two weeks. That is the fastest way to know whether the full paid tier is worth it. If you want more context on the browser-proxy ecosystem before committing, the antidetectreview.org/blog has deeper breakdowns on fingerprint mechanics and proxy type selection.
