Multilogin is a cloud phone platform built for social media marketers, agencies, and e-commerce operators managing multiple accounts. Instead of juggling separate tools for devices, browser profiles, and proxies, everything runs from one dashboard.

Each profile gets its own dedicated environment. For mobile-first platforms like TikTok, Instagram, Reddit, and Facebook, that means a real Android cloud phone โ€” a genuine, cloud-hosted device with real hardware identifiers, not an emulator. App data, cache, and login state persist between sessions, so accounts build history naturally. For web-first platforms like Google Ads and Amazon, that means an isolated browser profile managed from the same dashboard.

Built-in residential and mobile-grade proxies with automatic location matching are included on every plan, so there's no need to source proxies separately. Teams can assign profiles to members with granular permissions and scale from a few accounts to hundreds without switching tools.

Pricing:

Free: No time limit or credit card needed โ€” 5 cloud/browser profiles, 200 MB one-time proxy traffic, 1 mobile profile with 30 minutes of use. Pro: 10, 50, or 100 profiles at $7.08โ€“$26.67/month (annual) or $11โ€“$40/month (monthly). Adds monthly proxy/mobile-minute bonuses, quick cloning, bulk operations, and API access (team seats at the 100-profile tier). Business: 300โ€“10,000 profiles, starting around $57/month (annual) or $89/month (monthly). Includes unlimited team seats, custom API rate limits, advanced team management, and larger proxy/mobile allowances. Pay-as-you-go: $3.50/GB proxy traffic; ~$0.011/minute mobile time (up to 30% bulk discounts). Annual billing saves ~35% vs. monthly. Custom pricing available above 10,000 profiles.

Questions & Answers

As answered by people managing Diff Checker and Multilogin.

Who are some of the biggest customers of your product?

Multilogin's answer:

Multilogin's customer base spans agencies, SaaS platforms, and e-commerce brands managing multiple accounts at scale:

  • 411Locals - a digital marketing and SEO agency with offices across three continents, uses Multilogin to manage client accounts across social and search platforms.
  • InboxAlly - an email deliverability platform, relies on it for account separation in its own multi-account workflows.
  • Viva Naturals - an established supplement and wellness brand sold through Amazon and Walmart, uses it to keep e-commerce accounts isolated and organized.

Which are the primary technologies used for building your product?

Multilogin's answer:

Multilogin is built on Chromium and Firefox for browser profiles, with cloud-hosted Android devices (running Android versions 10 through 16) powering the Cloud Phones product. The platform supports automation through Selenium, Puppeteer, Playwright, and Postman, along with a dedicated API and full ADB access for teams running scripted workflows.

What makes your product unique?

Multilogin's answer:

Multilogin is built around two products working together: Cloud Phones, which are real Android devices hosted in the cloud, and browser profiles with isolated fingerprints. Most competitors offer one or the other, and having both under one dashboard means a team can run mobile-first platforms like TikTok and Instagram through genuine Android hardware, while managing web-first platforms through browser profiles with their own cookies, session, and IP. Everything stays organized in a single place, with proxies and mobile minutes included on every plan.

Why should a person choose your product over its competitors?

Multilogin's answer:

Multilogin covers both mobile and browser environments natively, so teams don't need to stitch together separate tools for app-based platforms and web-based ones. Built-in residential proxies across 150+ locations come with every plan, along with automation support through Selenium, Puppeteer, Playwright, and the Multilogin API. Pricing starts with a free plan offering 5 profiles, no credit card required and no time limit, which makes it easy to test the platform before committing to a paid tier.

How would you describe the primary audience of your product?

Multilogin's answer:

Multilogin serves agencies, social media marketers, e-commerce sellers, and media buyers who manage multiple accounts across social and e-commerce platforms. Teams running client accounts, multi-store operations, or large-scale content workflows use it to keep each account in its own separated environment while managing everything from a shared dashboard.

What's the story behind your product?

Multilogin's answer:

Multilogin started as a browser profile management tool and has grown into a broader cloud platform for teams running multiple accounts. As the product evolved, Cloud Phones were added to give users access to real Android devices for mobile-first platforms, expanding what started as a browser-based solution into a full multi-account management platform covering both web and mobile.

Multilogin Chrome Browser Alternative: Review In 2024
Hereโ€™s where we start to prove our claim Multilogin simply canโ€™t be called best in class anymore. The web app looks like good old Multilogin, only without the left side panel. Like many Multilogin alternatives, it has a clean and minimalist interface, but the cost of that is cut functionality.

  • How to convince someone lossless compression is possible?
    In what way did you show the file comparison? Did you use a diff like diffchecker.com ? If someone can see for themselves that every bit of data between two files is exactly the same, and still thinks they are different, IDK how you could get past that. x == x is pretty fundamental.

  • Advanced Diff Checker?
    How do I find the actual difference between two strings that appear equal to the naked eye? I used multiple tools and some show no differences, but some show differences. I got diffs on diffchecker.com, but it just shows me that they are different, but not how they differ. Is there a better tool for this? Source: over 3 years ago
  • Is there a library that allows to easily do diffchecks between two json?
