We make Mosaic, the local-first anti-detect browser. We tried to be fair about the prices below; corrections to hello@mosaicbrowser.com.
Undetectable.io prices by how many profiles you keep, so the bill grows with the library. Mosaic Pro is one price, $49 a month, for any number of profiles. Here is what each costs, read on 2 November 2026.
The prices side by side
| Undetectable.io plan | Price (USD, monthly) |
|---|---|
| Base | $34/mo |
| Professional | $69/mo |
| Custom (200 to 10,200 cloud) | $139/mo |
| Mosaic Pro, any number | $49/mo |
Figures are USD, billed monthly, from Undetectable.io's pricing page on 2 November 2026; 30% off yearly. Undetectable.io meters cloud profiles and seats; local profiles are unlimited on paid plans. Undetectable.io's free plan is 5 cloud profiles, 50 creations a month. Undetectable.io has no free trial.
Mosaic does not have a tier for ten profiles or a tier for a thousand. Pro is $49 a month and the thousandth profile costs the same as the first, because a profile is a folder on your own computer rather than a row in our cloud. That is cheaper than Undetectable.io once the count passes a few hundred, and more expensive at the small end; if you run a handful of profiles, Undetectable.io's entry plan or a free plan will cost less than ours.

How it works: Provider minting
Where Undetectable.io fits better
Undetectable.io gives you unlimited local profiles on paid plans and cloud storage. Mosaic has none of those: no team seats, no cloud copy of profiles, and no Firefox engine. Tesseract Chrome, our engine, is built for Apple-silicon Macs so far, with no Windows engine yet. If any of that is a requirement, Undetectable.io is the better buy whatever the price.
Where Mosaic is different
Every profile in Mosaic is a fingerprint, a proxy exit and a cookie jar that agree with each other, and all of it stays on your computer. The fingerprint values change in C++ inside the engine rather than in injected JavaScript, so a page reading its own functions finds stock Chrome code. A provider saved from one gateway line mints a separate session per profile, so a cheap proxy plan still gives each account its own exit.
When to pick which
Pick Undetectable.io if you run a small library, need unlimited local profiles on paid plans and cloud storage, or want a product on Windows or Linux today. Pick Mosaic if you run hundreds or thousands of profiles alone on a Mac and want one predictable bill. The counts and the full field are in what a cheap anti-detect browser really costs and the browsers with unlimited profiles. Mosaic Pro is $49 a month for any number of profiles, with the first 14 days free; Free holds 3 profiles and 10 profile creations.
