# Mosaic — the local-first anti-detect browser > A local-first anti-detect browser: its own Chromium, fingerprints from real hardware, a proxy exit per profile. One price, infinite profiles. Source: https://mosaicbrowser.com/ ## Every account gets a browser of its own. Run every account you are entitled to side by side, and keep the browser from tying them together: each profile has a fingerprint drawn from a real machine, its own proxy exit and its own cookie jar, checked before it opens. **Start with 3 free profiles, no card. Pro is $49 a month for any number.** Mosaic is a desktop app Email yourself the link and open it on your computer. ![The Mosaic profiles table: names, coloured tags, proxy locations and a Start button on each row](https://mosaicbrowser.com/shots/profiles-list.png) Illustration: one profile, as its values fit together. ## A profile is three things that agree with each other. A site links two accounts by something they share, a cookie or an address, and spots a made-up one by values that contradict each other, like a Windows browser reporting a Mac’s GPU. So a Mosaic profile is a fingerprint, a proxy and a cookie jar, and the whole product is keeping those three in step on your computer. ### A fingerprint Drawn whole from one real machine (GPU, screen, CPU, fonts, canvas and audio), so the parts agree. Set in C++ inside Mosaic’s own Chromium, never painted on with JavaScript a page can catch. ### A proxy exit Each profile browses through its own address. Mosaic measures where the proxy really comes out and sets the timezone, languages and location to match it: a Berlin exit gets a Berlin clock. ### A cookie jar Logins, cookies and 2FA codes live with that profile and nothing else. Encrypted on disk, kept on your computer, carried by no cloud and shared with no other profile. ## Numbers you can check, because nobody can promise “undetectable”. ## Change the proxy and the place changes with it. A Berlin address with a Texas clock is how accounts get linked. Mosaic measures where each proxy really comes out and sets the timezone, languages and location from there. The machine stays the machine; only the place moves. [How exit matching works](https://mosaicbrowser.com/features/exit-matching) Proxy exit The placefollows the exit The machinestays put Exit measured in Berlin, DE. Clock, languages and location drawn from it. ## Paste one gateway line. Get a different country for every profile. A residential seller hands you one gateway line with a session id inside it, and changing that id by hand for every account is your job. Paste the line into Mosaic once instead. It is kept as a template, each profile mints a session id of its own, and the country goes in using the word that seller’s line format has for it. - **One session id per profile.** Two profiles end up on the same exit only if you put them there, never because a line was copied. - **Country, state and city, where the seller has a word for them.** Ask for a city at a seller with no city key and Mosaic refuses it by name rather than dropping it. - **A dead session costs a new one.** Mosaic does not try the same token three times. A session you pinned stays pinned. [How minting works](https://mosaicbrowser.com/features/proxy-providers) Illustration. Mosaic reads each seller’s own format off the line you paste: 40 sellers in the table, 6 of them captured from real lines. ![A proxy provider in Mosaic: one gateway line that mints a separate session for every profile](https://mosaicbrowser.com/shots/provider-mint.png) *The provider in the app: one line, a session per profile.* ## 29 features, all of them on your computer.

Free holds 3 profiles with no card; Pro is 14 days free if you want everything at once. ### Install and sign in Drag Mosaic into Applications and sign in. It downloads its own browser once and checks it before unpacking. ### Bring your accounts Paste a proxy or one gateway line from your seller, or import exports from GoLogin, Dolphin Anty, AdsPower, Octo Browser or Multilogin. ## One price for all of them. Free for 14 days. Free for 14 days, then $49 a month. A card starts the trial, we email you 3 days before the first charge, and if you cancel before day 14 you pay nothing. The thousandth profile costs the same as the first. Or $490 a year: ten months' price, 2 months free. - **Infinite** profiles, creations and projects - The REST API and the MCP server - Every engine feature, on the same browser Free runs - Profiles open offline for up to 24 hours Or stay on **Free**: 3 profiles and 10 creations, no card, the same engine. ## The four we priced bill by how many profiles you keep. We don’t. Your profiles live on your disk and browse through proxies you pay for, so one more costs us nothing. At 300 profiles, the monthly bill comes to this. What 300 profiles cost a month, read 2 November 2026 Monthly billing, the cheapest plan that holds that many profiles, read on each vendor’s own pricing page on 2 November 2026: [Multilogin](https://multilogin.com/pricing/), [GoLogin](https://gologin.com/pricing/), [AdsPower](https://www.adspower.com/pricing), [Dolphin Anty](https://dolphin-anty.com/pricing/). Yearly billing is cheaper at all four. GoLogin: shown in euros to a European address, with the same figures. Prices change; check the vendor before you decide. [Try your own number](https://mosaicbrowser.com/pricing#calculator) ## Six things to settle before you install. ### Will my accounts get banned? Nobody can promise that, because a ban is the platform’s decision. What Mosaic does control is whether each profile’s fingerprint, exit, clock and cookies agree. They are checked before every launch, and you can run the profile against 49 public detectors and read the verdicts yourself. ### Does it run on Windows? Not yet. Tesseract Chrome, the Chromium every profile runs on, has no Windows build, so there is nothing for a PC to install yet. On a Mac, everything on this page works today. ### Can my Mac make Windows profiles? Yes, and the editor warns you first. A Windows profile gets a Windows GPU, screen and thread count, but its fonts, their metrics and the way text is drawn still come from your Mac, where no setting reaches them. On one Mac, IPHey scored a macOS profile 100 and a Windows one 80, so macOS stays the strongest match. ### Where do my profiles live? In a folder on your computer, encrypted on disk. Our server knows your plan, your computers and when a profile opens, by a random id. Never its name, cookies, proxy or browsing. [Exactly what it receives](https://mosaicbrowser.com/privacy#app). ### I use another anti-detect browser. Mosaic opens exports from GoLogin, Dolphin Anty, AdsPower, Octo Browser and Multilogin, tells which one made the file from its layout, and carries names, notes, proxies, start pages and cookies across. [How importing works](https://mosaicbrowser.com/features/import). ### Can my team share profiles? No. Mosaic has no seats and no shared workspace, because a profile lives on the computer that made it and both plans run on one computer at a time. If your team needs to share profiles today, a cloud-based tool will suit you better. ## How fingerprints, proxies and accounts work                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 [AI agent with multiple browser profiles: how to set it up](https://mosaicbrowser.com/guides/ai-agent-with-multiple-browser-profiles): An AI agent with multiple browser profiles keeps one persistent profile per account, so its cookies, exit and fingerprint never mix.
