Fingerprint Quality and Detection Bypass
The fingerprint engine is the most important component of any antidetect browser. It determines whether your profiles look like real users or get flagged as automated bots.
Undetectable Browser’s Fingerprint Engine
Undetectable Browser uses a Chromium-based engine with configuration-driven fingerprint generation. You select a target operating system and browser version, and the tool generates a matching set of fingerprint parameters — canvas hash, WebGL renderer, audio context, fonts, screen dimensions, and more. The approach relies on large databases of real device configurations to produce believable combinations.
The strength of this approach is variety: Undetectable claims access to millions of real device configs, so each profile gets a statistically plausible fingerprint rather than a randomized one. The weakness is that the base browser is still Chromium, which means Chromium-specific detection vectors (like certain WebGL rendering quirks or JavaScript engine behaviors) apply to every profile. For most platforms, this is not an issue, but high-security sites that specifically fingerprint the browser engine can sometimes distinguish a modified Chromium profile from a genuine Firefox or Safari session. Understanding how browser fingerprinting works at a technical level helps you evaluate these trade-offs.
Multilogin’s Mimic and Stealthfox Engines
Multilogin takes a different approach by maintaining two proprietary browser engines: Mimic (built on Chromium) and Stealthfox (built on Firefox). These are not just modified browsers with injected JavaScript — they are custom-compiled builds with fingerprint modifications made at the source-code level. This deeper integration makes the spoofing harder to detect because the modifications do not leave the telltale JavaScript injection artifacts that some detection systems look for.
Stealthfox gives Multilogin a genuine diversity advantage. Profiles running on a Firefox kernel produce fundamentally different fingerprints — different JavaScript engine behavior, different rendering paths, different default fonts — compared to Chromium profiles. For platforms that cross-reference browser engine consistency, having both kernel options available reduces detection risk.
The trade-off is cost and complexity. Maintaining two separate browser engines is expensive, and that cost passes through to users in Multilogin’s premium pricing.
Real-World Detection Rates
In community testing on sites like CreepJS, BrowserLeaks, and Pixelscan, Multilogin’s Stealthfox consistently achieves slightly higher pass rates than Undetectable’s Chromium-only profiles, particularly on tests that check for JavaScript injection artifacts. Mimic performs comparably to Undetectable’s engine on Chromium-specific tests. For everyday use cases — social media management, ad verification, e-commerce — both tools pass standard checks reliably. The difference shows up at the margins, on platforms with aggressive, multi-layered detection. If you operate on those platforms, learning how to bypass anti-bot detection at a deeper level will help you configure either tool more effectively.
Pricing and Value Analysis
Multilogin and Undetectable sit at opposite ends of the price spectrum for antidetect browsers. This section breaks down what you actually get at each price point.
Undetectable Browser Pricing
Undetectable offers a free plan with 5 cloud profiles and 10 local profiles — enough to test the tool but not enough for production use. Paid plans start at roughly $49/month for 50 cloud profiles with unlimited local profiles. The unlimited local profiles are a genuine differentiator: if you primarily work on a single machine and do not need cloud sync, you can store as many profiles as your hard drive allows without paying per profile.
The catch is that local profiles are tied to your machine. If your drive fails, those profiles are gone unless you manually back them up. Cloud profiles are limited and more expensive to scale. For managing multiple accounts across devices, the local-only approach becomes a bottleneck.
Multilogin Pricing
Multilogin positions itself as the premium option with pricing to match. Plans start at €99/month (approximately $108/month) for 100 cloud profiles. There is no free plan — only a limited demo. The higher-tier plans for teams with advanced role management and more profiles can exceed €200/month.
What justifies the price? Cloud-first storage means every profile is automatically encrypted and synced. You can access any profile from any machine without manual export/import. The proprietary browser engines (Mimic and Stealthfox) represent significant R&D investment. And the team features — granular role permissions, sub-team management, detailed activity logs — are the most mature in the antidetect browser market.
Whether that justification holds depends on your budget. A solo operator managing 50 profiles will find Multilogin’s pricing hard to justify when tools like Undetectable or Send.win offer comparable functionality for a fraction of the cost.
Send.win: The Middle Path
Send.win’s Pro plan costs $9.99/month ($6.99/month annually) and includes 150 profiles, 5 GB of proxy bandwidth, and the full Automation API. That is more profiles than both Undetectable’s and Multilogin’s entry plans at a lower price. The Team plan at $29.99/month ($20.99/month annual) scales to 500 profiles with 20 GB bandwidth and 16 team seats — still below Multilogin’s entry-level price.
Cloud vs Local: Where Your Profiles Live
Profile storage architecture affects everything from disaster recovery to team collaboration. Undetectable and Multilogin represent the two extremes of this spectrum.
Undetectable: Local-First
Undetectable’s design philosophy centres on local storage. Profiles are stored as encrypted files on your machine, with cloud profiles available as an add-on with strict limits. This approach has clear advantages: no dependency on external servers, no recurring cloud storage fees for local profiles, and full control over your data. It also means faster profile launch times since there is no network latency involved.
The disadvantages are equally clear. No automatic backup, no multi-device access for local profiles, and no team collaboration without manually transferring profile files. For regulated industries where data must remain on-premises, local storage is a feature. For everyone else, it is a limitation.
Multilogin: Cloud-First
Multilogin stores all profiles in encrypted cloud storage by default. Every profile syncs automatically across devices, team members access the same profile pool, and disaster recovery is handled by Multilogin’s infrastructure. The cloud architecture enables features like real-time profile sharing, instant handoff between team members, and centralized management dashboards.
The trade-offs: you depend on Multilogin’s servers being available, profiles take slightly longer to launch (a few seconds of download/sync time), and all your profile data resides on third-party infrastructure. For users handling sensitive accounts, this third-party dependency is a legitimate concern.
Send.win: Both Modes
Send.win offers the Sendwin Browser desktop app for local operation and cloud browser sessions for remote access. This dual approach means you can run profiles locally when you want speed and control, then switch to cloud sessions when you need access from a different device or a machine where installing software is not an option. Proxy browsers and cloud sessions complement each other — the desktop app handles high-volume automation while cloud sessions handle ad-hoc access and team collaboration.
Automation API Comparison
Automation is where these tools earn their keep for professional users. The API determines what frameworks you can use and how easily you can integrate profiles into existing workflows.
Undetectable Browser
Undetectable provides Selenium and Puppeteer API access on paid plans. You start a profile through the local API, receive a WebSocket debugging endpoint, and connect your automation script. The API is functional but straightforward — it handles profile launching and connection, while the actual automation logic lives in your scripts. There is no native Playwright support, which is increasingly a limitation as Playwright adoption grows in the automation community.
Multilogin
Multilogin supports Selenium, Puppeteer, and Playwright, making it one of the few antidetect browsers with comprehensive framework coverage. The API is well-documented and supports both local and cloud profile launches. For teams running complex automation stacks that span multiple frameworks, Multilogin’s broad compatibility is a genuine advantage.
Send.win
Send.win matches Multilogin’s framework support with Selenium, Puppeteer, and Playwright on both Pro and Team plans. The Automation API connects to the Sendwin Browser desktop app, giving you a local automation endpoint for each profile. For automation pipelines that need session isolation across hundreds of profiles, the combination of framework flexibility and affordable per-profile pricing makes Send.win competitive with Multilogin at a fraction of the cost.
Team Features and Collaboration
Team management capabilities vary significantly between these two tools.
Undetectable Browser
Undetectable’s team features are limited. Profile sharing is available on paid plans, but role-based access control is minimal. You can share profiles with team members, but you cannot define granular permissions — everyone with access can modify fingerprint settings, launch profiles, and change configurations. For small teams of trusted operators, this works. For agencies managing external contractors, the lack of permission granularity is a risk.
Multilogin
Multilogin offers the most mature team features in the antidetect browser space. Custom roles with granular permissions, sub-team structures, detailed activity and audit logs, and centralized billing. You can create read-only roles, restrict profile launching to specific team members, and track exactly who accessed which profile and when. For enterprise and agency use cases, these features justify part of the premium pricing.
Send.win
Send.win’s Team plan includes 16 seats with cloud-based profile sharing. Team members can access profiles through cloud browser sessions without installing the desktop app, which simplifies onboarding for contractors and freelancers. While Send.win’s role management is not as granular as Multilogin’s enterprise features, it covers the needs of most small-to-medium teams at a price point that is seven to ten times lower than Multilogin’s team plans.

Frequently Asked Questions
Is Undetectable Browser safe to use?
Yes, Undetectable Browser is a legitimate antidetect tool used by marketers, e-commerce sellers, and agencies worldwide. It stores profiles locally by default, which means your data stays on your machine. As with any antidetect browser, safety also depends on using clean proxies and maintaining consistent fingerprint configurations across sessions.
Why is Multilogin so expensive?
Multilogin’s pricing reflects its investment in two proprietary browser engines (Mimic and Stealthfox), cloud-first infrastructure, and enterprise-grade team management features. These are genuine engineering costs. Whether the premium is worth it depends on whether you need those specific capabilities — for many users, tools like Send.win deliver comparable results at a fraction of the price.
Does Undetectable Browser have a Firefox engine?
No, Undetectable Browser currently uses only a Chromium-based engine. Multilogin is one of the few antidetect browsers offering a Firefox-based engine (Stealthfox). If browser engine diversity is critical for your use case, this is a meaningful differentiator.
Can I use Playwright with Undetectable Browser?
Undetectable Browser does not natively support Playwright. It provides Selenium and Puppeteer API access. If you need Playwright support, Multilogin and Send.win both offer native Playwright integration. Send.win’s Automation API supports all three frameworks on both Pro and Team plans.
Which tool is better for large teams?
Multilogin has the most advanced team features with custom roles, sub-teams, and audit logs. However, its pricing for team plans exceeds €200/month. Send.win’s Team plan at $20.99/month (annual) includes 16 seats and 500 profiles — a more affordable option for small-to-medium teams that do not require Multilogin’s enterprise-level granularity.
Do I need to install software for Multilogin?
Yes, Multilogin requires its desktop application to launch and manage profiles, even though profiles are stored in the cloud. Send.win offers cloud browser sessions as an alternative — profiles run in the cloud and you access them through your regular browser with no local installation needed.
How does cloud storage differ between these tools?
Undetectable Browser stores profiles locally by default with limited cloud options. Multilogin stores all profiles in encrypted cloud storage with automatic sync. Send.win offers both approaches: the Sendwin Browser desktop app for local profiles and cloud browser sessions for remote access. This dual model gives you the speed of local storage and the flexibility of cloud access.
Which antidetect browser has the best fingerprint spoofing?
Multilogin’s Stealthfox engine provides the best fingerprint diversity thanks to its Firefox kernel, which produces fundamentally different fingerprints than Chromium-based tools. For Chromium-only comparisons, Undetectable and Send.win perform comparably on standard detection tests. The practical difference matters most on platforms with aggressive, multi-layered detection systems.
