Switch On Stealth Mode For The Internet

Physical Browser Isolation

Browse from a physically isolated anonymous browser, within a disposable cloud session, so that the internet never touches your real device.

Custom Fingerprint Engine

Control how you're seen online by generating randomized or handcrafted fingerprints that mask your real hardware, identity and behavior.

Built In Proxy Control

Easily route browser traffic through your own or our built-in proxy networks to appear in any location, without revealing your real IP address.

Persona Profiles

Create, save, and launch anonymous browser personas, each with its own fingerprint, proxy, and behavior, for tailored identities online.

Multi-Session Stealth

Run multiple anonymous browser sessions in parallel, each in its own isolated container, with independent fingerprints, proxies, and storage.

Web Based Control

Access everything through a lightweight browser-based dashboard, no downloads, or installs required, just login and launch.

Isolated Anonymous Browsers

Our cloud-based browsers offer complete anonymity when browsing the internet, with enterprise-grade managed attribution to support customized personas.

Manage Multiple Online Personas

Avoid Detection & Fingerprinting

Anonymity is the last true freedom.

Questions & Answers

How are you different from Brave, Tor, or Mullvad Browsers?

Brave is a US company mixing privacy with ads and crypto clutter. Tor offers extreme anonymity but painfully slow speeds and functionality issues. Mullvad Browser is ultra-private but barebones, and needs a VPN to shine. Tiger404 is different, it’s fast enough for everyday browsing, gives you total control over how you appear online and where you appear from, logs absolutely nothing, and it never interrupts you with ads. It’s privacy and anonymity without the compromises.

What makes you different from other privacy services?

Tiger404 is based in Uruguay, a privacy-first jurisdiction with no mandatory data retention laws, ourside of the major intelligence sharing networks. We log nothing. Ever. And unlike other services, we combine anonymity, speed, and ease of use, so you can browse freely, pay anonymously, and access our services anonymously.

Tiger404 is built on a foundation no privacy browser can match, we use a hardware, software, and network isolation model that physically air-gaps you from online threats and isolates every part of our infrastructure from every other part. Our browsers are completely non-persistent, no data is saved between sessions, so malware has nowhere to hide and no way to compromise either your browser or our systems. This non-persistent physical isolation is unique to Tiger404, making us architecturally closer to a cybersecurity company than a privacy browser provider.

This means our platform — and your browsing activity — are highly resilient to cyberattacks, and better able to protect your anonymity against cyber threats.

Where others promise 'privacy', Tiger404 gives you security and anonymity.

How is it different from anti-detect browsers?

Anti-detect browsers run on your device, meaning your real hardware is still exposed and you need to manage the setup yourself. Tiger404 runs in a physically isolated cloud container, the internet never touches your real device. Every session has a unique fingerprint, leaves no trace, and is destroyed when you’re done. You get full-stack privacy without the hassleof downloading and installing someones software.

Do you log anything behind the scenes?

No. We don’t log IP addresses, visited sites, timestamps, or any session data, nothing that could identify you. We are based where logging isn’t legally required, so even if someone asked, we have nothing to give. Your activity belongs to you alone.

How do you spoof my fingerprint ?

Each Tiger404 session launches with a unique, configurable fingerprint, a digital disguise for your browser. This prevents websites from recognizing you across visits or linking your activity. You can randomize everything (user agent, fonts, time zone, screen size, location) or set your own. When combined with our customizable proxy service, your true identity, location, and device are completely masked.

Can I run multiple personas or sessions at the same time?

Yes. You can run multiple isolated cloud browsers at once, each with its own fingerprint, IP address, and persona profile. It’s perfect for separating work, personal, and anonymous browsing without leaks or mix-ups. Each session is completely independent, only your saved profiles are persistent between sessions.

Is Tiger404 legal to use?

Yes. Many people use Tiger404 to manage separate accounts on social media, e-commerce, and other platforms without being flagged for “suspicious” activity. It’s completely legal in most countries you’re simply using privacy technology to separate your online identities. We stand for privacy, not crime, our mission is to empower law-abiding people to browse freely and stay in control online.

Tiger404 was the moment I took my privacy back. No more leaking data, no more silent profiling. I stopped being a target and started moving on my own terms.
