What Is Linken Sphere?

Linken Sphere is an antidetect browser for creating and managing isolated browser sessions, each with its own digital fingerprint, proxy connection, and cookies. It was created in 2017 and is operated by Legendary Software LTD. The app runs on 64-bit Windows 10 or later and on macOS 13 Ventura or later. There is no Linux, mobile, or web version.

Each session works as a separate browser profile. Fingerprint settings reach from the User-Agent down to Canvas, WebGL, and audio parameters. Hybrid 2.0 automatically builds a consistent fingerprint configuration, and Canvas 3.0 spoofs the Canvas fingerprint without distorting the image. WebRTC runs in an adaptive mode by default, which adjusts the spoofing to the connection type automatically. Linken Sphere claims its fingerprint spoofing passes the anti-bot systems of all popular platforms.

Configurations cover five browsers: Chrome, Brave, Opera, Edge, and Safari. From the Light plan up, mobile browser configurations add Android, iPhoneOS, and iPadOS profiles. The browser engine is clean Chromium, and Linken Sphere updates it within a couple of days of each official Chrome release.

Around the sessions, the app adds tools for daily work. These include tags and statuses, presets for mass session creation, cookie import and export, session warm-up, text input simulation, encrypted cloud sync, and a trash bin that keeps deleted sessions for 72 hours. Teams, action history, session backup, and a local REST API come with the higher plans.

For a proxy provider, the relevant point is that every Linken Sphere session takes its own proxy, set when the session or a preset is created. Proxies are not included in any Linken Sphere plan and are bought separately.

Key Use Cases

Managing many accounts from one computer.

Linken Sphere keeps each account in its own session with a separate fingerprint, cookies, and storage, so accounts on e-commerce and social platforms don't share one browser identity. The number of stored sessions depends on the plan, from 5 on the free plan to 1,000 on Premium. Giving each session its own proxy keeps the accounts from sharing one IP address as well.

Traffic arbitrage and ad accounts.

Media buyers use Linken Sphere to run advertising and affiliate accounts side by side and to test several creatives or offers at the same time. The Pro plan adds a Facebook manager, and mobile browser configurations cover campaigns that need an Android, iPhoneOS, or iPadOS browser profile.

Teamwork in agencies.

The Pro plan lets an owner create a team of up to 10 members, and Premium removes that limit. Roles cover owner, administrator, and member, and sessions can be passed between members with their cookies, fingerprint, and settings intact. Members work against the team owner's limits, so they can join even on a free license.

Browser automation and scraping.

On Pro and Premium, a local REST API creates, starts, and stops sessions, and each running session can be driven through the Chrome DevTools Protocol with Selenium, Playwright, or Puppeteer. Linken Sphere sets no request-rate limit on the API, so speed depends on the computer running it. Scripts that open many sessions in parallel need a proxy per session, which spreads the traffic across many IPs.

Mobile browser profiles.

From the Light plan up, mobile browser configurations build Android, iPhoneOS, and iPadOS browser profiles with their own mobile fingerprint, user agent, language, time zone, and geolocation. The emulation covers the mobile browser environment on a desktop computer. Linken Sphere lists crypto airdrop work, social media account management, and scraping of mobile sites among the uses for these profiles.

How Linken Sphere Works With CatProxies

Linken Sphere is a browser and does not include CatProxies proxies. CatProxies supplies the IP address each session connects through, and Linken Sphere handles the fingerprint, cookies, and profile isolation. The fingerprint separates the browser identity while the proxy separates the network identity, and a multi-account setup needs both.

There is no technical integration between the two products. A Linken Sphere user adds CatProxies proxies to a session or a preset. Neither product depends on the other to function.

Linken Sphere supports UDP on all plans, including Free. QUIC, HTTP/3, WebRTC, and WebTransport work through SOCKS5 proxies that support UDP, and a custom DNS can be set in the session settings. UDP traffic depends on the proxy as well, so it only goes through when the chosen CatProxies proxy supports UDP over SOCKS5.

Who This Is Best For

Linken Sphere suits media buyers, agencies, e-commerce sellers, and researchers who work with many accounts and want each one kept in its own browser profile. Pro and Premium fit teams that need roles, action history, backups, and API automation, while Free and Pure cover solo users with fewer sessions.

Residential and mobile proxies are a common choice for account work in an antidetect browser, because they present as ordinary subscriber-assigned IPs rather than datacenter ranges. The app needs 64-bit Windows 10 or later or macOS 13 or later, with at least 4 GB of RAM and 16 GB recommended for many sessions. It doesn't suit Linux users, and anyone handling a single account may not need an antidetect browser at all.

Pricing

Linken Sphere has a free plan with no time limit and four paid plans. Paying for 6 months at once takes 10% off, and paying for a full year takes 20% off. Payment is made by bank card or cryptocurrency, with more than 100 coins accepted, and EU customers can also pay by bank transfer.

On a yearly plan the monthly price drops to $24 for Pure, $72 for Light, $128 for Pro, and $240 for Premium. Proxies, accounts, and other resources are not included in any plan and are bought separately. Refunds are available within 14 days of purchase, except for proxy payments.

CatProxies partner offer: the promo code CATPROXIES gives 20% off the first purchase on Linken Sphere. The code goes in the Promo code field on the registration page. Linken Sphere's documentation states that promo codes work only for new accounts at first registration and can be combined with the 6-month and 1-year discounts. Prices are set by Linken Sphere and may change. Verify current pricing and terms on the Linken Sphere website before buying.

FAQ

Is Linken Sphere free?

Yes, there is a free plan with no time limit. It includes 5 sessions on one device, with sessions stored locally and no cloud sync, warm-up, or teamwork. Paid plans start at $30 per month for Pure, or $24 per month on a yearly plan.

What operating systems does Linken Sphere support?

Linken Sphere runs on 64-bit Windows 10 and 11, Windows Server 2016 to 2025, and macOS 13 Ventura or later, with separate downloads for Intel and Apple Silicon Macs. It doesn't run on Linux, mobile devices, or 32-bit systems. Minimum requirements are 4 GB of RAM and 40 GB of free disk space, and 16 GB of RAM with an SSD is recommended for many sessions.

Does Linken Sphere need proxies?

The browser runs without one. For multi-account work each session needs its own proxy, otherwise every profile appears from the same IP address however different the fingerprints are. Proxies are not included in Linken Sphere plans and are bought separately.

Which proxy types work with Linken Sphere?

CatProxies residential, mobile, ISP, datacenter, and IPv6 proxies can all be added to a Linken Sphere session. Each session takes its own proxy, so different accounts can run on different proxy types. Residential and mobile proxies are the usual choice for account work, and datacenter proxies fit scraping jobs where cost per IP matters more.

How does the CATPROXIES promo code work?

The code gives 20% off the first Linken Sphere purchase. Enter CATPROXIES in the Promo code field when registering a new account, since codes don't activate on accounts that already exist. The discount stacks with the 6-month and 1-year discounts.

Can a team work on the same sessions in Linken Sphere?

Yes. On Pro and Premium, the owner creates a team and sets each member's rights, from launching sessions only to creating, editing, and deleting them. A session sent to a colleague keeps its cookies, fingerprint, and settings, and every member works under the team owner's limits.

Is CatProxies part of Linken Sphere?

No. CatProxies and Linken Sphere are separate products with no technical integration. A Linken Sphere user adds CatProxies proxies to sessions independently, and neither product depends on the other to function.
